Q. I wish to paint an outside concrete area that has had a solvent sealer on it. Present colour is charcoal and I would like the finish colour medium brown. It is subject to foot traffic and the surface looks excellent when wet but when dry looks as if there is dirt/dust on it. What steps would I need from start to finish to achieve this?

A. We recommend moving to a solid paint finish such as Resene Non-Skid Deck and Path. If the existing sealer is based on an acrylic resin and sound then you should be able to apply two coats of the Resene Non-Skid Deck & Path over the cleaned surface.

Q. I am building a large partly covered external deck. I am considering two treatments for the 'floor' – either treated pine - I'd like to make it look white washed or if I used recycled timbers (like railway sleepers) for a deck - what paint treatment could I use so that it meets building code slip resistance levels?

A. The only stain effect you could achieve would be to use one of the Resene Woodsman Wood Oil colours. We have no trafficable exterior white blond effect for this application. There is also no way to produce a slip resistant finish with semi-transparent stains such as Resene Woodsman.

Railway sleepers are made from very hard dense timbers and are difficult timbers to stain. We would recommend Resene Woodsman Wood Oil, but this cannot give a slip resistant finish. Slip resistant finishes can only be achieved with film forming solid paint finishes, not stains.

Q. Am I able to paint a Formica shelf? If so, what preparation do I need to do?

A. Clean down with an abrasive cleaner such as Jif and then wipe clean and allow to dry. Prime with Resene Waterborne Smooth Surface Sealer, undercoat with Resene Quick Dry Waterborne Primer Undercoat and then apply two coats of any Resene waterborne enamel finish. We recommend Resene Lustacryl semi-gloss will give the best balance of gloss and wear. The paint system will take up to 5 days to fully harden and develop adhesion. Please note that the painted Formica will not have the same wear properties as the uncoated Formica.

Q. I’m looking at painting my floor tiles in shower/toilet/foyer. My shower is a ‘wet room'. What would you recommend for sealer and topcoats, preferably a non skid finish?

A. Painting of the tiles in this situation is a risky as paint delamination may occur. There are some applications where tiles are the best option and this is one of those.

September 2013

Q. I am having a new house built clad in fingerjointed treated pine weatherboards. Because the house is between two existing houses that have black stained weatherboards, we were hoping to have a dark charcoal colour for our paint but have been advised that this would cause unacceptable movement in the weatherboards. Can you advise what is the darkest grey/charcoal colour we could safely use on wooden weatherboards? - I believe your CoolColour™ range might provide more flexibility in this respect.

A. Suppliers of finger jointed pine weatherboards usually give an LRV (light reflectance value) that the paint colour must meet in order to get a guarantee. The LRV values are usually high and this does limit colour selection, however we can use Resene CoolColour technology to extend the colour range towards darker colours. If you can obtain the LRV cut-off that is the best starting point. The issue with painting timber cladding with dark colours is heat induced dimensional changes of the cladding, that is warping or cupping. The darker the colour the greater the tendency for dimensional changes to occur, usually more so on the northern elevation that receives the most sun exposure. Resene CoolColours reflect more heat and therefore assist in reducing the potential for dimensional changes to occur.

Q. We would like to paint the bare concrete block walls of a workshop beneath a car deck. It has two subterranean walls but they have good tanking. There has been some leaking down one of the block walls from a crack in the car deck above but this is currently being repaired and is the only water ingress issue. What sort of preparation do the walls need, and what paint would you recommend?

A. For a decorative paint finish and assuming the walls are now waterproof, seal with Resene Sureseal and then apply two coats of any Resene interior acrylic paint, such as Resene Lustacryl semi-gloss waterborne enamel or Resene SpaceCote Low Sheen waterborne enamel to give the hardest wearing finish.

September 2013

Q. Can I apply waterborne Resene Woodsman to an existing oil based stain on roughsawn cladding? What is the best primer for painting anodised aluminium window frames?

A. If the oil based stain is Resene, then yes you can apply Resene Waterborne Woodsman over it provided the oil based stain has weathered for at least six months. To prepare anodised aluminium window frames, scrub down with Resene Paint Prep and Housewash, rinse off with clean water allow to dry and then prime with Resene Vinyl Etch.

September 2013

Q. To minimise flaws on the cladding of a house what paint and colour is best, i.e. light or dark - have a dark roof (Karaka).

A. It really depends upon the ‘flaws’. In general the visual impact of minor surface defects is best dealt with by applying a low gloss paint and in a light colour. What is the cladding material and level/extent of the flaws?

September 2013

Q. Is there a timber decking polyurethane that has anti-slip qualities?

A. We do not recommend using clear polyurethane type coatings for exterior timber. An aggregate additive would need to be added to the clear to achieve slip resistance and this results in an unacceptable finish as the aggregate remains visible in the clear.

September 2013

Q. I have an older villa with past coats of paint over wallpaper. I wish to repaint but do not want to remove all paint and paper. I have removed much and have plastered and sanded but not perfectly. Is there an embossed paint or a rough textured paint that I can put on that will partly disguise the bumpy surface and make it look acceptable?

A. If you hang lining paper first over bare plasterboard, then texture in Resene Sandtex applied in a crows foot technique you would be able to remove it when it was time to change. The other way would be to sand with 80 grit sandpaper and hang paint on paper over the lot then paint in your chosen Resene colour.

September 2013

Q. Many years ago I bought a Resene roof paint which gave a rather rusty roof many years more life. It had metallic flecks in it. What is the new equivalent?

A. If it was a waterborne paint then it probably was Resene Hi-Glo Metallic which has now been replaced with Resene Summit Roof Metallic. The product contains a pigment known as micaceous iron oxide (MIOX) which lays down like overlapping fish scales in the paint film; the pigment reduces the moisture vapour transmission of the coating and thus improves corrosion resistance. However application of an appropriate priming system to bare galvanising/Zincalume is the key determinate of corrosion resistance. The topcoat is usually considered to be more decorative than functional.

September 2013

Q. I have specified a wallpaper to go under a kitchen bench. Is there a clear spray or paint I can use to protect it and make it wipeable?

A. Many years back a clear acrylic sealer was recommended for this but with the advent of modern vinyl based papers this should no longer be a requirement.

October 2013

Q. I am painting a cement wall in Resene Bright Red. I have been told to use a grey undercoat. Is this the right thing to do?

A. The new plaster will need to be sealed with Resene LimeLock before application of finishing systems. The use of a grey undercoat of the correct shade can facilitate coverage of some topcoat reds where the opacity of the red is below what is usually found with whites and other tinted colours that achieve full opacity with two coats of topcoat colour.

October 2013

Q. I'd like to confirm that it would be suitable for previously stained cedar cladding (exterior) to be washed and sealed (with Resene Sureseal) before painting to successfully cover the existing dark brown stain. The existing stain is waterborne.

A. Assuming the existing waterborne stain is weathered then scrub down with Resene Deck and Timber Wash (treat with Resene Moss & Mould Killer first if mould/algae is present), rinse off with fresh water and allow to dry then apply Resene Sureseal. Apply Resene Quick Dry Waterborne Primer Undercoat as the undercoat then apply two coats of Resene Enamacryl gloss or Resene Lustacryl semi-gloss waterborne enamel finish. If using a dark colour use the Resene CoolColour™ version of the colour.

October 2013

Q. Do you have a paint that I can use to paint over a bare aluminium window (approx. 70s)?

A. Scrub it down using Resene Roof and Metal Wash, rinse clean with water and allow to dry. Prime with Resene Galvo-Prime, apply Resene Quick Dry Waterborne Primer Undercoat as the undercoat then apply two coats of Resene Enamacryl gloss waterborne enamel or Resene Lustacryl semi-gloss waterborne enamel in your selected colour (use the CoolColour™ version of your chosen colour if available).

October 2013

Q. I have stripped off old wallpaper from plasterboard (possibly papered in the 80s). In some places it has pulled the outer layer of protective paper covering off the plasterboard. I can sand it back but what product do I need to seal it before I paint it? It is a but fluffy where I sand, and it is only one part of a wall that has come away. I don't really want to put another wallpaper up. It is only the toilet so not a huge area. Hoping you have an easy solution!

A. If you look at the data sheet for Resene Broadwall Surface Prep and Seal, the second page has recommendations for painting after removal of wallpaper. If the removal of the paper face has left a deep depression then you can resurface using Gib® stopping compound, sand smooth then seal off the entire wall with Resene Sureseal.

October 2013

Q. We are painting our building and the painters have found that the heat of the sun is causing the weatherboard/paint to shrink back in the parapet area above the verandah. Can you please advise if there are any CoolColour or paint preparation options that will allow us to use the colour we have or do we need to choose a lighter colour?

A. We have CoolColour™ versions of a wide range of Resene colours. CoolColours have increased heat reflection (higher TSR, total solar reflection) compared to the standard versions and this will assist in reducing but not eliminating heat related stress on the cladding. CoolColours need to be applied over a white basecoat for optimum effect.

October 2013

Q. I am on the hunt for a chalkboard paint that would be suitable to use on porcelain/china mugs.

A. Our best system would be Resene Waterborne Smooth Surface Sealer then Resene Blackboard Paint. The Resene Waterborne Smooth Surface Sealer is designed for excellent adhesion so will help hold the topcoat onto the cup.

October 2013

Q. How do we prepare and paint tyres to make them into an ottoman?

A. Wash down with Resene Paint Prep and Housewash to remove dirt and road grime with scrubbing and rinse off with fresh water. Allow to dry then prime with Resene Roofing Membrane Primer followed by 2-3 coats of Resene Hi-Glo gloss waterborne paint tinted to the required colour. Usually you will require two coats but some bright colours will require a third coat to achieve colour uniformity. To avoid runs care is needed to ensure that there is not an excessive build-up of wet paint in the tread detail.

October 2013

Q. Can you please tell me if it is possible to use a roller to apply Resene Crescent (from your metallics range) instead of spraying and still get the effect of the mica sheen?

A. Spray application of any metallic paint will always will give the best uniformity of finish, however the Resene range of Enamacryl Metallics have been formulated to facilitate application with the recommended roller sleeve and if correctly applied can give a uniform finish which is not to dissimilar to a spray finish.

October 2013

Q. We are about to paint our new swimming pool. We want a finished (when pool if filled) colour that is between an aquamarine and turquoise. What is the base colour we should use?

A. Resene Swimming Pool paint only is available in the standard factory colour, other colours can made in Resene Armourchlor HBF but are subject to a disclaimer re performance.

October 2013

Q. I am looking at specifying Resene Foundry CoolColour™ over Linea weatherboard cladding for a residential coastal project. Could you please provide your recommended specification for the paint system and any advice would be appreciated?

A. Our standard system for Linea is Resene Concrete Primer followed by two coats of Resene Lumbersider (low sheen) or Resene Sonyx 101 (semi-gloss). To achieve maximum CoolColour benefit you will need to apply a white basecoat prior to applying the CoolColour topcoats; in this case the white basecoat is Resene Quick Dry Waterborne Primer Undercoat (this is an additional coat applied over the Resene Concrete Primer).

October 2013

Q. The suppliers of the timber cladding for our new house require a paint surface with an LRV over 40% for guarantee purposes. Can you please advise what is the darkest colours in the grey/charcoal/black spectrum that would meet these requirements in either standard or your CoolColour ranges?

A. The LRV of a standard and CoolColour version of a colour are the same, what differs is the total solar reflectance. While there is no direct relationship between the LRV of a colour and the TSR (total solar reflectance) of a colour, we do have a numerical way of calculating if a colour with an LRV of less than 40 can be used when the colour version is applied. Any grey colour lighter than Resene Stack should meet the requirements.

October 2013

Q. Do you guarantee against colour fading?

A. Fading of a paint colour is an inevitable consequence of weathering, the degree of fading is mainly a function of the pigments used to produce a colour. There are two main types of pigments, inorganic and organic, the latter are more prone to colour fade upon exterior exposure. If the colour is based on inorganic pigments then the colour will give the best resistance to colour fade. As colour fade occurs due the weathering (UV exposure) the degree of colour fade will be higher on elevations that receive the most direct weathering.

Resene has offered for many years an ultra violet stabilised clear for application over a pigmented base colour where the base colour has reduced resistance to colour fade due to the makeup of the colour.

October 2013

Q. I have previously used a waterborne enamel in 'white' to paint both interior and exterior of cedar window and door joinery. In order to get a decent white coverage we needed to use four topcoats. Joiners that I have spoken to have said that an oil based topcoat should be used to get better coverage and better performance.

A. Coverage has nothing to do with the paint type, it is about the application rate of the paint. For cedar you will need to prime with solventborne Resene Wood Primer and then I suggest that you undercoat with Resene Quick Dry Waterborne Primer Undercoat and then you should only need to apply two coats of a white topcoat to get coverage.

October 2013

Q. We have a dining table which is chipboard wood veneer dark brown. We're wanting to paint it a charcoal or black. I was just hoping you could assist in giving a guideline in how to best prepare and paint the table (lightly sand, prime, etc.)?

A. If the table has been polished you will need to remove any polish residues by wiping with RALI Wax and Grease Remover, changing cloths at least every three wipes. Sand with 220 grit sandpaper but avoid heavy sanding as this may cut through the veneer layer and then apply two coats of Resene Lusta-Glo (semi-gloss) tinted to your required colour. Leave the table in an area with good ventilation to allow the solvents to be released. The Resene Lusta-Glo may appear glossy when first applied but the gloss settles down to a semi-gloss finish over 7 days.

October 2013

Q. We have an exterior wall that I wish to repaint. There are cracks which have seeped a white substance. Before I repaint the wall, I am seeking some advice as to what type of sealer I should use to prevent the seepage in the future. I think the wall is block rendered with cement..

A. The white seepage is efflorescence and is caused by water moving through the walls bringing dissolved concrete salts to the surface and when the water evaporates it leaves the dissolved salts on the surface. You will need to expose the crack areas and repair using Rockcote Multistop, then spot prime the repairs with Resene Sureseal and reapply the topcoat system of Resene Lumbersider. Check the back has been waterproofed otherwise the problem may continue with water coming through from one side to the other.

October 2013

Q. How do you remove old paint off varnished wood?

A. It’s best to sand or use a paint stripper.

October 2013

Q. Do we need to use a particular type of paint on the kitchen walls? Also, we have a piece of wood that runs behind the sink and oven, assume this would be painted the same as the doors/skirtings? Does this need to be a high gloss seeing as it is in contact with water? Normally do you use the same colour as the doors/skirtings for the ceiling too? Or is that normally a different tone/colour? Is there special ceiling paint too?

A. Generally service rooms – kitchens (and bathrooms and laundries) require an enamel paint as the rooms are jeopardised with steam, food born stains, soap and cleaning products and often require 'tough' paint films to withstand all of that. These days most people favour a less shiny paint finish so all the rooms in the house have a similar type of paint finish. Resene SpaceCote Low Sheen waterborne enamel - Kitchen & Bathroom formula with extra silver fungicidal protection is the most popular. However, some people need a bit more sheen and prefer Resene Lustacryl Kitchen & Bathroom (semi-gloss) waterborne enamel. I usually recommend a mix of both – Resene SpaceCote Low Sheen Kitchen & Bathroom formula for walls, Resene SpaceCote Flat Kitchen & Bathroom on ceilings and Resene Lustacryl Kitchen & Bathroom for all skirting boards, door frames, doors and window frames and sills.

For people who adore the rich wet looking sheen of a full gloss there is Resene Enamacryl (gloss waterborne enamel) which can be used for all woodwork instead of Resene Lustacryl. That strip of wood between the sink and oven needs a paint that will take hard cleaning and be able to withstand everything - but the choice of sheen level is up to you - either Resene Lustacryl semi-gloss or Resene Enamacryl gloss.

Solventborne (turps based) enamels are still available but they take longer to dry.

Often ceilings and woodwork are the same colour - but not always - in this particular case you need to decide whether to do either the same as walls for the ceilings or highlight the ceiling more with the lighter colour.

The paint that is often seen in 10 litre pails and is called Resene Ceiling Paint is recommended in rooms other than wet areas. Resene SpaceCote Flat is a waterborne enamel that can be used on ceilings and is washable - one version of this product has a fly deterrent in it and another has extra mould additive in it as well as anti-bacterial silver protection.

October 2013

Q. Can you please advise what the difference is between Resene Woodsman and Wood-X when used on cedar? Is Wood-X a water or solventborne product?

A. Wood-X is a mineral oil (with a small amount of solvent, fungicide and resin - to help hold any colour pigments to the timber) also commonly known as a 'wood oil'. These types of oil treatments for timber never dry as opposed to vegetable/plant based oil types, which do dry, though slowly, due to the oxidation process. The mineral oil type products (Wood-X) penetrate into the cell structure of the timber and thereby reduces the potential for cellular space water uptake providing some dimensional stability to the timber. It also continues to move in the timber and as more is added it fills the air voids in the cells of the timber. It can migrate out if dark colours or sun exposure is high on a wall area. This is not seen as normal for wood-oils. Wood-X could be classified as a ‘solventborne product', though it is NOT classified as Flammable under Class 3.

Resene Woodsman stain comes in solventborne and waterborne options and is a stain. Stains, though based on many different types, are generally based on vegetable/plant based oils that do dry over time. The advantage of these stain type materials is that they are very easy to recoat and if in the future you decide that you want to paint your boards, once suitably prepared you can, as opposed to if your timber had been coated with a ‘mineral oil’ which never dries and therefore can not be painted over due to the potential of it to migrate and lift off any paint coatings that have been applied.

Both are semi-transparent finishes that aim to give the timber a coloured natural look and are both easy to recoat as they break down by weathering.

It comes down to the owner to which ‘look’ they like best, an oil or stain, and each differs only very slightly. So then it is how easy to recoat (both are similar) and whether they may change their mind in the future and want to paint.

Mineral oils have been around for decades, and have been mainly used by architects to give a natural finish and better dimensional stability to the timber.

One is not better than the other, it is purely an informed choice that the homeowner or building owner needs to make.

October 2013

Q. I want to paint old exterior wooden fencing - it is in very weather worn condition and I am after a single product that I can use to prime, seal and repaint it. The finish need not be brilliant as it is only a fence but there is a lot of it and I am hoping to avoid too much mucking about beforehand - what product would you suggest?

A. Treat the fence with Resene Moss & Mould Killer, leave for 48 hours then low pressure water wash. Allow to dry then apply two coats of Resene Lumbersider. Normally we would recommend priming with our solventborne Resene Wood Primer before applying the Resene Lumbersider for the optimum decision.

October 2013

Q. I have a bathroom area with a large glass skylight allowing a lot of U.V. light and summer heat to contact the painted Villa board. What paint will not ‘yellow and peel’ for this area? I am planning to use Resene Quarter Thorndon Cream.

A. The best system would be to prime the substrate with Resene Sureseal, lightly sand to de nib then applyResene Quick Dry Waterborne Primer Undercoat followed by two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom. Allow the paint system to dry with good ventilation for at least 48 hours before subjecting the painted areas to steam or condensation.

October 2013

Q. I need to paint some doors that have been polyurethaned. What sort of sealer would I need to use?

A. We recommend Resene Waterborne Smooth Surface Sealer. This product is designed as an adhesion promoter to help the rest of the paint system to stick to the surface. Please note that the product is not designed to give a high film build or have high opacity.

November 2013

Q. How long do I need to leave the primer paint on before I put on the topcoat?

A. Primers should always be overcoated as soon as possible, but depending upon the primer type most can be left for up to a maximum of a month before topcoating. Wash down prior to topcoating and check if the exposed primer has undergone chalking (white deposit can be rubbed off the primer surface). If there is chalking you will need to wash down with Resene Paint Prep and Housewash, lightly sand and re-apply the primer.

November 2013

Q. The paint on my roof has oxidised, white powder on fingers etc and I wish to repaint. I can waterblast but would prefer a less aggressive wash if possible. Do you have a product for this cleansing?

A. Application of Resene Paint Prep and Housewash, while wet scrub down and then wash off using fresh water is our recommendation for removal of surface chalking. Care needs to be exercised as the surface can become slippery. Also if you are using the roof for collection of drinking water you will need to disconnect downpipes to the collection tanks during preparation and for a few showers of rain after painting.

November 2013

Q. A question - can 'Bug Juice' be used as a spray around the house? We live in a rural area and summer brings cockroaches. If so please provide detail for application.

A. Bug Juice can only be added to a waterborne paint, and when added to paint the paint cannot be sprayed, so unfortunately it would be unsuitable for the spraying you wish to do.

November 2013

Q. I have a cedar home that was stained 4 years ago. I want to know how to best identify when/whether it needs restaining. Are there any visible signs I should look for? It has been stained a greyish colour and on the North and Western walls the stain is definitely fading and it almost has a whitish chalky appearance.

A. Usual triggers for restaining are stain erosion, appearance of areas of bare or greyed timber particularly on elevations that receive the highest exposure to weathering, north and northwest elevations. Most manufacturers of semi-transparent stains do have a recommendation for application to maintain the stain and this is an average time. It is not prudent to wait until the stain is at or close to stain failure. Resene Woodsman stains are designed to erode upon weathering and on average will need a maintenance coat every third summer but this is subject to exposure conditions and does vary with elevation.

The appearance is consistent with breakdown of the stain. Before restaining, scrub down the existing stain using Resene Paint Prep and Housewash, rinse off with fresh water and allow to dry then check that the prepared surface is chalk free and sound. If not repeat the wash down procedure then apply two coats of Resene Woodsman stain.

If there is mould/moss/algae present treat these with Resene Moss & Mould Killer.

November 2013

Q. I am wanting a high quality waterborne tint that contains no glycols.

A. The term glycols covers a large range of chemical entities. As a general class glycols are used in many colourant formulations to ensure that the colourant does not dry out and thus can be dispensed at point of sale. All Resene machine colourants are non VOC (contain no formulation component that has a boiling point less than 250 degrees celsium) and are ethylene and propylene glycol free.contains no glycols I want to paint our roof with Resene Rustic Red roof paint and I also want to paint the window trims in the same colour. When I test it on the window frames I get a colour that is much brighter than the colour chart. Can you help me understand what is happening?

A. The difference may be due to gloss level and possibly the size of the chip versus a larger area. Resene colour charts and testpots are low sheen finish. Resene Hi-Glo is a gloss finish. Higher sheen finishes will look cleaner and brighter. Lower sheen and flat finishes look duller and muddier.contains no glycols Can you provide guidance for painting over an oil based paint (internal windows) with a waterborne paint?

A. Assuming the existing paint system is sound, wash down with Resene Paint Prep and Housewash and wipe down with a cloth and cleam water. Allow to dry then sand the old enamel to a dull finish using 180 or 220 grit sandpaper, dust off and apply c followed by two coats of any Resene waterborne enamel topcoat.

November 2013

Q. How do we treat vinyl wallpaper prior to repainting as the wallpaper seems too difficult to remove?

A. Apply Resene Vinyl Wallpaper Sealer to the vinyl wallcoverings and then you can apply any Resene waterborne paint system.

November 2013

Q. I'm wanting to know what Resene products are suitable for painting over a butynol deck? The deck is weathered, and there is a slight fall on the deck to drain water, although it pools slightly in places before evaporating.

A. Scrub down using Resene Paint Prep and Housewash and rinse clean with water then allow to dry. Prime with Resene Membrane Roofing Primer and then apply two coats of Resene Lumbersider.

If you select a dark colour then apply Resene Quick Dry Waterborne Primer Undercoat white over the primed surface as a basecot and use the CoolColour™ version of the Resene Lumbersider colour. This will not make the surface cool to touch but will give a painted surface that reflects more heat than the same colour made using conventional colour pigments.

November 2013

Q. What type of paint can be used on either plaster or cement surrounding a fireplace?

A. If you can maintain hand contact when the fire is burning then it can be painted. If not and it is too hot to maintain hand contact then it should not be painted. The best system is to use Resene Sureseal then Resene Lusta-Glo solventborne semi-gloss paint. Solventborne enamels give the best heat resistance but there may be yellowing of the colour over time.

November 2013

Q. I have plaster revealed window sills in the bathroom and kitchen that may be exposed to a small amount of water flicking onto them. I need an undercoat/sealant that will act as a barrier to prevent the water from penetrating into the plaster.

A. Use Resene Solventborne Aquapel, apply until the plaster surface will not accept any more liquid.

November 2013

Q. What can I use for a baby’s cot?

A. You can use Environmental Choice approved Resene waterborne enamels, such as Resene Lustacryl semi-gloss waterborne enamel; however do not use the Kitchen and Bathroom versions for this application. After painting leave the cot to cure in a well-ventilated area for at least two weeks and prior to use wipe down the surface with warm water and a cloth.

November 2013

Q. I have an old villa with acrylic topcoat on weatherboards. I will fill and spot prime with Resene Quick Dry. Can I then apply Resene Sonyx 101 semi-gloss over the old paint system or does it all need a coat of Resene Quick Dry primer first. It will be washed, deglossed and sanded.

A. Resene exterior acrylic paints such as Resene Sonyx 101 can be applied to prepared sound/clean existing acrylic painted weatherboards. The only word of caution is if you are looking to apply a dark colour over many layers of existing light coloured paint. The heat associated with the darker colour will stress the existing paint and can cause an old layer of paint to fail which is seen as blistering. It is always wise to assess the integrity of the existing paint by adhesion testing (Resene ColorShop staff can advise methodology) prior to repainting with the new colour. If you choose a dark colour then use the CoolColour™ version of the colour as this will offer better heat reflection compared to the same colour made using standard colorants.

November 2013

Q. How do I remove waterbased paint overspray from a Perspex skylight?

A. Meths will usually soften and sometimes dissolve waterborne paints to allow their removal form a surface. In your case the adhesion of the paint to the Perspex may be such that removal may require multiple treatments with a rag soaked in meths. Suggest that you check first on an inconspicuous area that the meths does not react with the Perspex and cause it to become cloudy as this can happen.

November 2013

Q. Can you recommend a paint to go on existing and new tiles on an outside deck? A grey colour would be good to get the new glazed tiles to match with existing. There is an outside patio below the deck.

A. We recommend using Resene Waterborne Smooth Surface Sealer as the adhesion primer for glazed tiles. The tiled area will need to be clean and free or all contaminates. As a precaution I would advise treating the area with Resene Moss & Mould Killer as a prep step (per label directions), rinse well with fresh water and then leave to dry before applying the Resene Waterborne Smooth Surface Sealer. Please be aware that the Resene Waterborne Smooth Surface Sealer is not designed to achieve any significant film build or opacity, only a thin dry film is required. Leave the Resene Waterborne Smooth Surface Sealer to cure for 48 hours before applying two coats of a Resene exterior acrylic such as Resene Lumbersider for colour.

November 2013

Q. Is there a fire test result for 12mm thick 'A' grade plywood? Or would it be under same group number as 9mm?

A. The same Group rating applies for any thickness of a given substrate greater than the thickness reported in the test report. So the Group rating stated for 9mm will be the same for 12mm ply.

November 2013

Q. I have downloaded Resene Paint Systems Fire Ratings Sheet. This gives me the information on the wall and ceiling only. Can you please give me the Group number for Concrete Floor with Resene Aquapoxy topcoat?

A. There is no Group rating required for flooring; however the coated floor must meet a critical radiant flux (CRF) value. Flooring products on non-combustible flooring (concrete) can be treated as having a CRF of >4.5 Kw/m2, given this we have not considered it a requirement to have the CRF value determined experimentally. (Refer to DBH Codewords Issue 57 August 2013).

November 2013

Q. We have recently moved into a two year old house with painted internal walls. The walls have marks on them and I would like to know how to clean them off without having to repaint the entire house. Can you suggest a product to use that will not damage the surface?

A. We recommend you try Resene Interior Paintwork Cleaner, available as a concentrate or pre diluted. Click here to view our advice on caring for your paint finish.

November 2013

Q. I have an old printed concrete sloping driveway towards the house. Can I restain or paint over in something that's not slippery? I can acid wash the sealer/paint off and it looks like bare concrete underneath. I would like charcoal or something dark.

A. Suggest Resene Non-Skid Deck & Path. Remove the existing coating then you can acid etch. Ensure that when the acid is applied to the concrete that it bubbles and then wash down well with copious amounts of fresh water and allow to dry before priming with Resene Sureseal. Then apply two coats of Resene Non-Skid Deck & Path in your selected colour.

Q. Can I paint the canvas seat and back cover on my director’s chair? I presume a particular paint is required? Is it easier to spray paint or hand paint the wooden part of the directors chair - do I need a special sort of paint?

A. We do not have a dedicated paint for this purpose but you could try a thinned down version of a Resene Lumbersider colour, the potential issue will be cracking of the applied paint film onto the flexible canvas. We suggest brush painting of the wooden sections. If there is moss and mould that will need to be treated prior to painting.

November 2013

Q. I have a situation where I was planning to install a stained glass creation, but have been told that in this situation I can only install safety glass. Because I wish to have a coloured design on this glass door, I am researching the possibility of having an artist paint a mural type artwork on the glass, allowing clear spaces on the top half of the mural whilst creating opacity on the bottom half, more or less.

A. The only paint we sell for glass is a two component paint that must be spray applied and given these two features it is really not suitable for mural painting. Solventborne gloss enamel paint such as Resene Super Gloss does have good adhesion to a cleaned glass surface and this may be a better option for you to consider.

November 2013

Q. Do you supply paint that does not need undercoat please?

A. You can use Resene Summit Roof for painting galvanised and Zincalume roofing and the like as long as the substrate has not undergone more than 6 months weathering; for timber (sound, no deterioration due to weathering) use Resene Lumbersider. The performance of paints are dependent upon the substrate condition and the use of direct to substrate topcoats over marginal surfaces will always end up in a reduction of the paint life. A good option for indoor furniture would be to prime with Resene Quick Dry Waterborne Primer Undercoat then apply two coats of a Resene waterborne enamel finish such as Resene Lustacryl. The waterborne enamels are not self-priming, but are a harder finish with better wear resistance than Resene Lumbersider.

November 2013

Q. We have cedar weatherboard finished with a weatherboard and fencing stain. After four years it is already deteriorating. Do you have product that would last longer, or am I best to resort to painting? In either case, would I need to strip back the existing film of the stain?

A. All semi-transparent stains are high maintenance compared to a solid paint finish. Resene Woodsman stains are non-film forming which makes re coating simple as there is no issue with flaking or loss of adhesion of the coating. On average a timber substrate painted with either of the Resene Woodsman stain versions - waterbornne or solventborne - will require a maintenance coat every third summer. The frequency of recoating is determined by exposure conditions and elevation - north and west elevations are more exposed to weathering and coating breakdown.The Resene Woodsman stains cannot be applied over a film forming stain. A paint finish will require painting less frequently, though generally it takes a lot more time to prep a painted surface prior to repainting than it does for a stained surface.

November 2013

Q. I have a mobile trailer unit of toilet cubicles which are lined with Seratone on the walls, and some kind of fibreglass membrane over plywood on the floors. I want to paint the whole thing with something that can be hosed down easily enough but also will not crack under the pressure of the unit being towed/used. What is the best way to go about this?

A. We can recommend paint systems for both substrates but cannot give any guarantee re the ability of the paint to resist cracking due to substrate flexing, which is what I assume happens when the unit is mobile. Ensure there are no soap residues on the surface then sand down to a dull finish and apply Resene Armourcote 221 epoxy primer followed by two coats of tinted Resene Uracryl 402. Ensure ventilation is maintained during application and allow the paint to cure for five days with good ventilation before exposing the painted surfaces to water.

November 2013

Q. What type of paint do we need for our fascia?

A. You can use any Resene exterior acrylic finish for painting prepared and primed fascia boards, the most commonly used is Resene Sonyx 101, which is a semi-gloss finish. If planning to use a dark colour then recommend using the CoolColour™ version of the colour. If the fascia boards have been painted with a light coloured finish over many years you will need to check the soundness of the existing paint if changing to a much darker colour as the heat on the surface associated with the darker colour can cause an older layer of paint to fail and blister. CoolColours assist by increasing the reflection of heat from a dark colour but cannot be guaranteed to do so in a manner that will overcome any adhesion weakness of older paint layers.

November 2013

Q. We have painted cork tiles for our kitchen with white water based prep coat-sealer-primer and wish to coat with a clear lacquer that doesn't yellow or appear yellow over the white (checkerboard of black and white tiles). Which is the best gloss finish to use?

A. Resene Aquaclear does dry clear but the dry film does have a slight yellow cast to the film which will alter the whiteness of the white. The degree of yellowness in the dry film of Resene Aquaclear is small compared to traditional solventborne varnishes.

November 2013

Q. I have a property with satin polyurethane finished interior rimu window reveals. We are redecorating using your products and have decided we would like to paint them as the timber has faded and in some cases discoloured. What is the correct preparation and undercoat to use?

A. If the existing polyurethane clear is sound and clean then lightly sand with 220 grit sandpaper and apply the following system: Resene Waterborne Smooth Surface Sealer, Resene Quick Dry Waterborne Primer Undercoat and then 2 coats of Resene Lustacryl. The system will need a minimum of 5 days to develop final adhesion.

November 2013

Q. We have an outdoor precast concrete fire which we want to paint black. Obviously it gets hot although not real hot. What can we use?

A. If the surfaces to be painted can withstand hand contact when the fire is at full heat then it can be painted. If this is the case then seal the concrete with Resene ConcreteSeal 3in1 and follow this with 2 coats of Resene Uracryl 402 Black.

November 2013

Q. I am in the process of rewallpapering. I have stripped the very old wallpaper but it has torn shallow depressions in the old plasterboard, and there are a few really old mould stains that were starting to come through all the layers of old paper. Can I use the Resene Moss & Mould Killer on this old plasterboard effectively, and if not how can I remove them, and stop them from coming through the new paper?

A. Yes you can use Resene Moss & Mould Killer to treat the areas of mould. The appearance of mould can suggest the area is prone to dampness so it would be sensible to see if there is a water ingress issue where the mould is present.

November 2013

Q. I have recently built a bird house and was just wondering what I could put on it in order to make it waterproof? I was thinking of using craft paints.

A. Normally for a bird house you could paint it with standard exterior house paints – e.g. Resene Lumbersider (which comes in Testpots) or similar. The only time that wouldn’t be recommended is if it is immersed in water (e.g. a bird bath). House paints aren’t designed for water immersion – for that you would need a Swimming Pool Paint or similar. We generally wouldn’t recommend craft paints as they don’t tend to have the kind of exterior durability required.

November 2013

Q. I am planning to paint Resene Summit over asphalt tile roofs – what preparation will I need to do?

A. Prepare with Resene Deep Clean, then leave for at least 2 weeks then waterblast. Apply 1 coat of Resene Membrane Roofing Primer over the bare asphalt the 2 coats of Resene Summit Roof.

For simply restoring colour, Resene Summit Roof works well. A thorough clean-down and removal of moss and lichen is required before coating (old chip tiles are often covered in organic matter, especially south-facing surfaces). Whether a primer is required really depends on the amount of chip remaining on the roof and the condition of the roof. Resene Summit won’t be suitable for re-chipping. For most people the work would require a professional painter.

November 2013

Q. We are looking for a product to apply over plasterboard to give a sandy textured finish.

A. Resene Sandtex is effectively a paint style coating that has a grit texture in it, which can be either sprayed for a uniform grit finish or applied in a criss cross pattern for a more visually interesting effect. Available in a huge range of Resene colours.

November 2013

Q. We have tiles in a splashback area and are wanting to alter colour. We know you can paint tiles in Resene Waterborne Smooth Surface Sealer and then what else would we need to meet the fire rating requirements for a kitchen behind a stove etc?

A. We don’t recommend paint being applied on top of splashbacks next to stoves or similar, due to the direct exposure of the painted surface to heat, oils/fats and cooking splashes. You would be best to get a new splashback backpainted in your chosen Resene colour, even if you just install it over the existing one (depending on the space available), or if limited room then remove the old and replace with a new one.

December 2013

Q. What would you recommend for repainting a kitchen counter in our home?

A. If we are dealing with Formica and similar and a pigmented system is required then the topcoats will be a waterborne enamel then best to use Resene Waterborne Smooth Surface Sealer as an adhesion primer, then Resene Quick Dry as an undercoat and topcoat in your choice of Resene Enamacryl gloss waterborne enamel or Resene Lustacryl semi-gloss waterborne enamel.

November 2013

Q. We are going to paint our kitchen and lounge ceilings. We live on a farm so we have a bit of a fly problem. Which product would best to use – Fly Deterrent or Bug Juice?

A. Bug Juice is most effective against crawling insects as opposed to flies who tend to land and then depart relatively quickly. The insect needs to be in contact with the painted surface for sufficient time to absorb the active material and the amount required to kill is also a function of body weight. On both requirements flies are less likely to suffer mortality than ants or other crawling insects.

The Fly Deterrent additive is not designed to kill on contact or uptake of the active agent but to repel flies and discourage them from sitting on the surface. The less they sit on the surface the fewer the fly spots. The repellence is only there close to the surface so using the product will not deter flies from entering or remaining in the room air space.

Of the two products, Bug Juice would be better of the two for you, but in a rural situation with a major fly issue the most effective control may be to use time release spray units as these generate airborne insecticide that will have a greater effect on the fly population.

November 2013

Q. Is the paint in your testpots, real paint, the same quality we would get in the large tin. I was worried it is a cheaper composition just to help select colour?

A. The paint in Resene Testpots is mainly Resene Lumbersider, so yes the same paint as you would get in the Resene Lumbersider paint cans. Some of the testpot paints are Resene Enamacryl Metallic (for the metallic paints), Resene Waterborne Woodsman (for the exterior wood stains) and Resene Colorwood (for the interior wood stains). They are all the same formulations as you would find in the larger pack sizes for those products.

November 2013

Q. How do I turn a mid-dark brown oil-based paint to black?

A. It is unlikely that you can change the colour to a true black. Black is achieved by addition of a black tinter to a base containing no other pigments and in your case this requirement cannot be achieved.

November 2013

Q. What is the recommended white paint to use for ceilings in residential homes?

A. The most popular product that retail customers use in areas like lounges is Resene Ceiling Paint, which is available in 10L pails. It's not suitable for wet areas. If they want a colour then the most popular choice is Resene Alabaster, which is just off white. This can be tinted into a range of Resene ceiling paints.

Resene SpaceCote Flat is our best ceiling paint option as it is wipable so that fly spots etc can be wiped off, it can be used in all areas - including lounges and wet areas such as bathrooms and kitchens and tints true to the colour chart (whereas the Resene Ceiling Paint colours tend to have a slight variation from the chart due to the nature of the product).

If cost isn't an issue then Resene SpaceCote Flat is the best performing ceiling paint option for most areas. For wet areas we recommend Resene SpaceCote Flat Kitchen & Bathroom with anti-bacterial silver and Resene MoulDefender.

December 2013

Q. I need to repaint a COLORBOND® roof and I want to know if your paint system will reduce the heat inside the house.

A. If the roof has weathered for at least a month you can apply Resene Summit Roof to the washed roof (use Resene Roof and Metal Wash to clean it down first). If you use the CoolColour™ version of the colour you select this will reflect more heat than the same colour produced with conventional colour pigments. The effect this may have an effect on the interior temperature wich will vary from project to project.

December 2013

Q. How to I deal with mould on wallpaper?

A. If the wallpaper is washable, use warm soapy water and a sponge or wallpaper cleaner. Always wash according to the level of washability of the wallcovering and test a small inconspicuous area that you are washing first to make sure it’s not going to discolour.

Different wallpapers have different washable properties and will be affected differently by mould.

December 2013

Q. I'm after a deck finish for Purple Heart. I believe I need to use a transparent penetrating oil based sealer with UV inhibitors in a trans-oxide pigmented ‘cedar tone’ to keep the colour.

A. The colour of purple heart timber does fade out relatively quickly upon exterior exposure. The timber is also very dense and staining when new is a challenge. We would recommend letting the timber weather for a couple of months then apply two coats of tinted Resene Woodsman Wood Oil Stain in a colour to suit.

December 2013

Q. I am currently looking to repaint the front of my house. It is subject to high sun and wind and there are now a number of bare wood areas after washing down.

A. What you describe can only be attributable to failure of the factory applied primer, which is why you have ended up with bare patches as the original factory applied primer has failed and has taken the remaining paint system with it.

December 2013

Q. We have just moved into an A-frame house which features a tongue and groove ceiling panel that is polyurethaned. We'd like to paint out the ceiling similar to the same panels on the walls which have been painted in the past. Would like to know what type of paint to use - we have been told an etch primer? We know we will need to sand the surface back to a dull finish. We are not after an immaculate finish, because the timber is quite knotty. We won't be doing much by the way of filling etc. We would like a solid white like colour - have considered a blonde wash, but would like a more solid colour look.

A. You will need to ensure that the ceiling is free of dirt, dust, soot etc then apply Resene Waterborne Smooth Surface Sealer as the adhesion primer, leave for 48 hours then apply two coats of either Resene Ceiling Flat or Resene SpaceCote Flat. Ensure good ventilation during drying. The advantage of the Resene SpaceCote Flat is that it can be cleaned without damage to the flat finish of the paint.

December 2013

Q. How do I treat moss and mould?

A. Moss and mould problems:
On painted surfaces, mould looks like dirt, and frequently the two cannot be visually distinguished.

The most common species are black, but others can be brown or green. By wetting the surface and rubbing, mould will show up as slime.

Mould is a major cause of paint disfigurement. It destroys the paint's fresh clean appearance, and if left unchecked it shortens the life of the paint film. Unless removed within a few months of its appearance, mould penetrates the body of the existing film and once firmly established, will grow through subsequent paint coatings, impairing adhesion and ruining the appearance of the paint work.

What to do:
Thoroughly clean down to remove all loosely adhered material. Treat areas of moss or mould infestation with Resene Moss & Mould Killer, correctly diluted (see pack) with clean water. As soon as the mould has been completely de-colourised (which indicates it has been killed) wash thoroughly with clean water to remove residues.

Once the moss and mould is completely removed and the surfaces have been correctly prepared, proceed with the Resene recommended paint system.

Mould is likely to occur in humid areas, such as bathrooms. Always make sure areas like these have adequate ventilation otherwise the mould is likely to reoccur.

Resene has a range of Kitchen & Bathroom products formulated with anti-bacterial silver and Resene MoulDefender to help inhibit bacteria and mould growth.

December 2013

Q. What paint could I use to paint the top bench surface and sink on a resin bathroom vanity unit? We don't like the pink and want to make it white.

A. The only possible system would be to apply Resene Armourcote 221 as the primer then apply two coats of Resene Uracryl 402 or 403 in your chosen colour.

January 2014

Q. Our 3 bedroom house build in the 1970s has a Summerhill stone block/brick exterior painted in white. It was last painted in 1994 by the previous owners. I have waterblasted the exterior, sealed the mortar between some of the blocks I had replaced and am trying to decide which finishing product would be best, Resene Sonyx 101 or Resene Lumbersider.

A. In principle being a semi-gloss finish Resene Sonyx 101 will have a longer time to the onset of chalking compared to Resene Lumbersider (low sheen); however low sheen finishes are often preferred for painting substrates with texture. The decision is really based on personal preference but the higher gloss level will be easier to wash down and clean.

January 2014

Q. Can I paint directly over Resene Timber Surface Prep or do I need to put an undercoat/primer on before the topcoat?

A. You need to coat the Resene Timber Surface Prep with a coat of Resene Quick Dry waterborne primer undercoat prior to application of acrylic topcoats.

January 2014

Q. I am painting wooden weatherboards which I am stepping back to bare timber as original paint layers are badly cracked and flaking off. Where the bare timber has been exposed to weather for some time can I use Resene Wood Primer as I will be using this to prime the rest of the weatherboards I am stepping back to bare timber? Or if I need to pretreat these affected areas with Resene TimberLock can this be used for the rest of the weatherboards instead of Resene Wood Primer - or is it necessary to use both paints?

A. Greyed areas of timber are due to the timber being exposed to weathering for an extended length of time. You would need to thoroughly get back to the original timber colour if you were to use Resene Wood Primer. Alternatively we recommend application of Resene TimberLock as the prep treatment for severely weathered timber, light sanding to remove loss timber fibres is required. Prepare and treat greyed areas with Resene TimberLock then apply the Resene Wood Primer.

January 2014

Q. I have varnished resin bathroom vanity unit. I've been told to that you have a sealant/undercoat product that is perfect for going over these, allowing me to just give them a light sand without having to remove all trace of the varnish. Can you tell me which product I should use?

A. The product is Resene Waterborne Smooth Surface Sealer.

January 2014

Q. Can we spray 10 year old (waterblasted clean) wooden fences with an airless gun to apply Resene Waterborne Woodsman stain? The quantity would obviously increase but we are not sure if an airless gun is possible?

A. Yes using a FFT414 spray tip and low pressure. Have someone on the opposite side holding a large dropsheet to control overspra, and a piece of cardboard at the bottom is also a good idea. Anything you don't want stained should be covered or masked.

January 2014

Q. I am looking for a clear lacquer/varnish to go over bricks surrounding a 1920s fireplace. Ideally I would like to add a pigment to modify the colour of the bricks. Do you have a product suitable for this application that is ok with high temperature?

A. If you can maintain hand contact on the surfaces to be coated when the fire is in use then painting is possible.

January 2014

Q. I have painted some shelves with white Resene Lustacryl three months ago. There is a mark on it so I want to do another coat. Will the paint adhere or should I sand with 220 grit or less?

A. Sand with 220 grit sandpaper and undercoat with Resene Quick Dry waterborne primer undercoat then apply the two coats of Resene Lustacryl.

January 2014

Q. I have white gloss drawers - can I just sand to remove the gloss then paint with Resene Lustacryl?

A. Sand with 220 grit sandpaper before re application of Resene Lustacryl.

January 2014

Q. Can we paint the exterior of our house and fence after 5pm in the summer?

A. I would not recommend undertaking exterior painting using waterborne paints that late in the day even over summer. Waterborne paints need to dry to the point where they are resistant to moisture. When you apply paint late in the day there is always the possibility of condensation from dew forming on the paint before the paint has achieved sufficient cure to resist damage from water.

January 2014

Q. Have you got a product that seals hand painted china/ceramic cups? The paint keeps rubbing off. It would obviously need to be clear and safe for drinking from after curing time.

A. The underlying problem is the adhesion of the paint used to the glazed pottery, not sure what type of paint was used but I am not aware of a sealer that can be used to 'glue' the applied paint to the pottery surface.

Resene Waterborne Smooth Surface Sealer can be used as the adhesion primer for waterborne paints onto glazed pottery but pottery painted with this system will not survive cleaning in hot water or dishwashing.

January 2014

Q. Our windowsills get very hot and crack. I understand there is a sealant that I can use to put on first, leave to cure and then paint with under coat and paint. Can you tell me the name of this product? Also I am told you have to remove all the paint. What would I use to do that? Heat gun or paint stripper or scraping?

A. The existing paint will need to be removed back to bare timber and the timber thoroughly sanded. For small areas such as sills a heat gun and a scraper is the best way to remove the paint. How old is the current paint system? If the property is old and there have been many layers of paint applied there may be lead based paint present. If this is the case then ensure that the heat gun operates at a temperature of less than 400°C, place a drop sheet on the ground to collect all paint flakes and bag in a sealed plastic bag for disposal. Make sure that you wear a dust mask during removal of lead based paint. Fill cracks with the Repaircare system. When applying the Repaircare epoxy smooth to level during application as the product is difficult to sand smooth when cured. Prime the sill with Resene Quick Dry primer undercoat then apply two coats of a Resene waterborne enamel, such as Resene Lustacryl (semi-gloss) or Resene Enamacryl (gloss).

January 2014

Q. How do we remove old paint from windows and doors?

A. Paint can be removed from timber doors and windows using a heat gun and a scraper or with a paint stripper such as Sea to Sky. If the old paint contains lead you will need to ensure that the heat gun operates at a temperature less than 400 degrees celsius to ensure that the lead in the paint does not become volatile and present a health hazard to the person removing the paint. Lead base paint flakes should be bagged for disposal and care taken not to contaminate the ground or other areas with lead based paint residues. Always wear a mask when removed lead based paints. Testing kits for lead based paint can be purchased from Resene ColorShops.

January 2014

Q. I need to repaint a roof which has shingle tiles (the kind with granules on them). Some of the granules have worn off in some areas. What are the best products for cleaning then repainting such a roof? I will be spraying the roof and preferably waterblasting to remove lichen etc. Will waterblasing cause problems for the existing surface?

A. Apply Resene Moss & Mould Killer to the roof taking particular care to saturate lichen growth. Leave the roof to weather for at least two weeks then waterblast to remove lichen growth. Waterblasting may remove a quantity of the original chip so we suggest that you disconnect your downpipes during waterblasting and for the duration of time after the Resene Moss & Mould Killer treatment. Prime any bare areas of base metal or bitumen with Resene Galvo One then apply two coats of Resene Summit Roof.

January 2014

Q. Can I use Resene Lumbersider as an undercoat under Resene Sonyx 101 or Resene Hi-Glo instead of a tintable acrylic undercoat over good condition previously painted timber?

A. As long as the timber is correctly primed and if there is an existing paint system that is sound and correctly prepared then yes. However you cannot use Resene Sonyx 101 or Resene Lumbersider if you are topcoating with a solventborne enamel or two component polyurethane.

January 2014

Q. I've just built a new (H3 treated) pine deck. I want to protect it. What is the difference between using a Deck Oil as opposed to a Deck Stain, is it just the colour, or are there other differences?

A. Clear coats offer significantly reduced UV protection to the underlying timber.

January 2014

Q. We have some outdoor furniture which has a dark brown stain. The furniture was purchased about four years ago and the paint finish is badly weathered. We don't know whether the stain is water based or oil based. How can we determine this?

A. The test for a standard acrylic paint is to see if the paint is softened or removed with meths.

January 2014

Q. I’m building a house. I am having a feature wall with wallpaper. Do I mount the TV before I hang the wallpaper or after and why?

A. It is usual to paper the whole wall then fix appliances. The only situation I can see any benefit in wallpapering after fixing the unit is if the TV is to be placed in a wall recess.

January 2014

Q. Can you please advise what I can mix into acrylic paint to make it thicker? I am wanting to paint on canvas and have a lot of texture in the paint to make it three dimensional.

A. We do not recommend trying to thicken our paints. If you are wanting to achieve a texture then use Resene Thixalon. However as you apply thicker paint films there will be a tendency for the paint to crack if the canvas is flexed. When using Resene Thixalon as the paint you cannot roll the canvas up.

January 2014

Q. I need your advice to use Resene Sandtex and Resitex texture product. What sort of spray machine can I use?

A. You will need to use a hopper gun set up. Details are on the product data sheets.

January 2014

Q. I'm wanting to paint an exterior brick wall with a smooth surface. I've tried a test spot with Resene Lumbersider and seems okay so far. Can you recommend if a primer is needed first and if the paint I'm using is okay for smooth brick?

A. Bricks must be clean and free of any applied waterproofing treatment. If the bricks are unglazed use Resene Sureseal as the sealer; if glazed then use Resene ConcreteSeal 3 in 1.

January 2014

Q. We have a building that heats up to over 40°C. There are ten 10 metre lengths of skylight which add to the heat. Is there a UV blocking paint we could use to reduce the heat coming through but not block the light in the winter?

A. The reduction we achieve with Resene CoolColour™ technology does require a total light block. I am not aware of any light transparent coating that achieves what you want.

January 2014

Q. We are building a new house and are cladding the exterior in rough-sawn plywood with battens. We are currently staining them prior to putting them up. We are using Resene Woodsman waterborne stain. Can we do both coats on the pieces of plywood prior to putting them up? Or do you recommend leaving the second coat until the cladding is up?

A. Standard practice is to apply one coat prior to installation and then a second coat after installation of the weatherboards.

January 2014

Q. Is there any special primer for painting kwila timber, not with a stain but a white paint? If so which primer and which paint for the topcoats?

A. New Kwila contains a water soluble stain which can discolour acrylic paint systems. The other issue with Kwila can be adhesion due to the dense surface that is to be painted. Out best recommendation is to wash the timber down using Resene Timber and Deck Wash - this will remove the water soluble material and open up the surface to paint. Allow to dry then prime with Resene Wood Primer. Then apply Resene Lumbersider if a standard acrylic finish is required or Resene Non Skid Deck and Path if a non-skid finish is required.

January 2014

Q. Can I paint over wood previously finished with one coat of boiled linseed oil? I wish to use a wood stain/varnish over the top.

A. The linseed oil should develop into a hard film. However the wood will be sealed and this will make application of a wood stain difficult as the stain cannot penetrate into the timber. You can apply clear varnishes (solventborne such as Resene Qristal Polyurethanes) to the oiled timber after giving the timber a light sand.

January 2014

Q. How can I paint acrylic over plastic?

A. If you are using standard decorative acrylic paints then it depends upon the plastic type, acrylic paint (waterborne) will adhere to uPVC and acrylic sheeting such as Perspex. However poor adhesion occurs when these acrylics are applied to polyethylene and polypropylene plastic materials.

January 2014

Q. I want to paint a reproduction Queen Anne table with 4 chairs and 2 carver seats. How do I strip the varnish off this old mahogany furniture? Dip stripping is not an option... too expensive.

A.You can strip the existing coating with Sea to Sky paint stripper which is available from Resene ColorShops.

February 2014

Q. Have Resene considered reducing the amount of thinners and replacing it with more solids in their solventborne products to reduce the odour?

A. The answer is yes. Our approach has been two fold. The development of low VOC paints has been at the forefront of Resene R&D for the last 30 years. Our policy has been to replace solventborne paints with a reduced VOC version but only if the performance characteristics of the lower odour version meets or exceeds that of the paint being replaced. Our list of Environmental Choice Approved products is extensive. The odour of the majority of decorative solventborne paints is due to the aromatic content of the solvents used to formulate the paints. We have introduced versions of a number of shelf line enamel primers, undercoats and top coats which are formulated using solvents with less than 1% aromatic content. These are sold as lower odour versions and while the total VOC has not changed, they are lower odour compared to enamel formulations using traditional solvents such as white spirits and mineral turps.

February 2014

Q. As property managers we are always having to deal with scuff marks on painted walls! Abrasive cleaners leave marks and dull the paint. Please advise an effective method for our tenants to use.

A. Removal of scuff marks is a function of the material causing the marking and the resistance/toughness of the paint finish. Unfortunately there is no single non-abrasive cleaner that will remove all marking without causing a level of damage to the paint finish.

The Resene waterborne enamel wall paints are more resistant to damage during cleaning than paints formulated on conventional acrylic resins. As a general rule the higher the paint gloss level the easier cleaning is; current preference for many is to use low or flat paints as the wall finish. For details on how to clean the surface see the Resene Caring for your paint finish brochure available on this website.

February 2014

Q. I have a plaster home previously whitewashed which is chalking badly. It’s being chemwashed and Resene X-200 is to be applied. Do I need to coat with Resene Limelock or other primer first?

A. The sealer to use post chem washing is Resene Sureseal, you need a sealer that will bind any residual chalking and Resene Sureseal is recommended for this.

February 2014

Q. I have used the same paint roller and sleeve with Resene Zylone Sheen low sheen paint on several rooms, several weeks apart, and have just wrapped the sleeve in plastic bags between rooms without cleaning. This system has worked well until now. This last room smells very bad and I have traced this to the roller and sleeve. I think it's ‘gone off’ and the smell is offensive and doesn't appear to be abating. It has been suggested that I wash the walls with white vinegar although I believe that I should probably recoat with Resene Sureseal (to hopefully block/remove the smell) and then topcoat again with Resene Zylone Sheen low sheen. Your advice/recommendation would be appreciated please.

A. The issue could be due to bacterial contamination from the roller sleeve used. Would suggest wiping the walls down with a 1-2% hypochlorite solution, leave for 24 hours then wipe down with copious quantities of water and a cloth to remove any bleach residues or byproducts. If the painted wall paint has been contaminated with bacteria this should kill the bacteria on the surface of the paint and the smell may not be present. Leave for a couple days and if the smell has gone then you can apply another coat of the wall paint.

Q. We have concrete/plaster finish planters where the soil dampness causes discoloration of the plaster. Could we use Resene Sureseal inside the containers? If used outside we then would like to paint them a colour using Resene Lumbersider.

A. In theory yes, however Resene Sureseal will not necessarily give a barrier to the passage of water. I suggest that you first treat the interior and exterior surfaces of the planters with Resene Solventborne Aquapel then apply the Resene Sureseal. Resene Aquapel is a water repellent which will add to the barrier properties of the painted areas.

February 2014

Q. I work at a gallery and we repaint our walls about 6 times per year. What paint would you recommend? We are looking for white, low sheen, something that doesn’t protest too much to touch-ups.

A. I would recommend Resene SpaceCote Flat or Resene Zylone Sheen VOC Free. Both products have been assessed using the Oddy test method.

February 2014

Q. I have a dresser that I stripped and oiled with linseed oil about 8 years ago; I'd now like to paint it. Could you please recommend primer/paint, and should I sand it first?

A. Assuming that the oil used previously has dried to a hard finish the following applies: degrease using Resene Interior Paintwork Cleaner and then lightly sand to provide a mechanical key for the new paint. Prime with Resene Enamel Undercoat then apply two coats of either a solvent or waterborne enamel topcoat, such as Resene Lustacryl semi-gloss waterborne enamel.

February 2014

Q. Can you make up non Resene paint colours or other colours?

A. If you have a sample of what you want matched just bring it into a Resene ColorShop. They can either match it in store or send to our Colour Lab for matching.

February 2014

Q. I have outdoor polyprop chairs that are faded and look ghastly. Could you advise how to paint these please?

A. Sorry but polypropylene is one plastic that we cannot provide a paint system for (paint does not adhere well to the plastic).

February 2014

Q. What do I prime plywood with before applying the Resene Magnetic Magic paint?

A. Resene Quick Dry waterborne primer undercoat.

February 2014

Q. I recently purchased a house which, after a week and some rain, old water stains and paint blistering appeared on the ceiling. The roof was leaking. We replaced the old tiles with a new roof. The blisters, prior to the roof replacement seemed to disappear when the weather was fine and reappear when it rained. This is still occurring in the same places, despite the new roof. Is the roof still leaking? Or are the bubbles from the initial leaking? I am really worried that the new roof has been a complete waste of money.

A. Blistering paint on ceilings is usually associated with water on the reverse side of the painted ceilings. There is a possibilty that the blisters can re-appear with increased humidity associated with rainfall but it’s not that common. When the blister re-appears next time cut one to see if the blister contains water, this should give a definitive answer to the leak origins. Also check if there is any ceiling water piping that runs on top of the affected area.

February 2014

Q. I have wooden kitchen cupboards that were painted blue, and I want to paint them white. What sort of paint should I use?

A. Sand to a smooth dull finish and apply Resene Quick Dry waterborne primer undercoat then apply two coats of a Resene waterborne enamel such as Resene Lustacryl (semi-gloss) or Resene Enamacryl (gloss).

February 2014

Q. I have a new home repaint job and the plasterboard stopper recommended the homeowner use pigmented sealer on all the wall and ceilings. Do I need to?

A. New stopped plasterboard must be sealed before application of topcoats; for wet areas the Resene product is Resene Sureseal; for all other areas, Resene Broadwall Waterborne Wallboard Sealer.

February 2014

Q. We have put up a new paling fence (1.8 m high and and around 25 m long). What stain would be recommend? How much would we need? How do we protect it from graffiti?

A. For staining you can use Resene Waterborne Woodsman or Resene Woodsman Wood Oil Stain. However you cannot overcoat a stain with a coating from which graffiti can be removed. For this system you will need to apply two coats of a solid colour in Resene Lumbersider then overcoat with two coats of Resene Uracryl GraffitiShield.

February 2014

Q. We are going to reclad our house with cedar wood and have a Resene testpot called Woodsman Treehouse. We are comparing it with oil based stains. What is the difference between oil based and water based stains in terms of appearance, maintenance, heat, etc? What is a cold stain and how can we achieve this? We understand putting cedar in a dark stain attracts heat and this ultimately makes the wood age/appear scruffy faster?

A. Resene has two versions of Woodsman – Resene Woodsman Wood Oil Stain is a solventborne and Resene Waterborne Woodsman which is waterbone. There is no difference in the recommended recoat times of either version. The waterborne version is available in CoolColour™ formulations, which reflect more heat (the difference is relative) than the same colour made using non CoolColour technology. The increased heat reflectance of the CoolColour technology does reduce the risk of dimensional changes in the boards which is an added benefit.

February 2014

Q. I have a cedar clad home which has weathered over about 25 years. My wife wants me to paint it with your CoolColour black but my concern is that it will cause the cedar to buckle. Your advise would be appreciated.

A. Within the range of timbers used for cladding, cedar is the most dimensionally stable. Application of Resene CoolColour™ Black finish to appropriately prepared and primed cedar is the best way to reduce the risk of dimensional changes occurring due to the selection of black as a colour.

We use TSR (total solar reflectance) as the measure of heat reflection for colours, the TSR of black made using a conventional black pigment is 4.5% increasing to 25.2% for the CoolColour™ version (both are measured over a white basecoat, this gives the maximum cool colour effect). The CoolColour will still be warm to touch but reflect significantly more heat than the conventional colour. There is no known relationship between dimensional change of a timber and TSR but the benefit of using a CoolColour topcoat can be substantiated. Alternatively you could select a lighter colour, closer to the natural timber colour.

February 2014

Q. A major job needed on the (exterior) windows and sills of this 1980 house. I have sanded away part of a sill, but with the passage of time cannot be sure what kind of timber it is. I want the best paint solution. Am prepared to sand all back if needed.

A. The ID of timber can be problematic, Totara is usually distinguishable by the dark colour of the timber, cedar/redwood has a characteristic odour when sanded. Not so easy for other native timbers such as Rimu and Kauri, although Rimu can be a dark orange brown colour but it depends upon where the timber was cut from. If the property was constructed in the early 80s it is unlikely to have native timbers used for joinery, more likely to be redwood or cedar.

I would endorse total removal of existing paint. Given the difficulty in determining the timber you may have to carry out a test area. If the timber is redwood/cedar the primer will be Resene Wood Primer. (The other timber primer is Resene Quick Dry waterborne primer undercoat; this primer is for all timbers but specifically for priming Totara and Matai, if applied to Redwood/Cedar there will be tannin bleed which will continue to come through a waterborne paint system). Repair cracked putties using RepairCare DrySeal in accordance with the manufacturer's instructions (available from Resene ColorShops). Once the appropriate primer is selected then the following paint system is recommended - undercoat Resene Quick Dry waterborne primer undercoat, topcoat Resene Enamacryl CoolColour™ version of the colour if available.

February 2014

Q. My hallway ceiling has some cigarette staining from the previous owner - what is the best way to clean this and do I need to seal it before I paint it?

A. Wash down using Resene Paint Prep and Housewash in accordance with label directions, wipe down with clean water, allow to dry and apply Resene Sureseal. Then you can apply two coats of Resene topcoat. Generally Resene SpaceCote Flat or Resene Ceiling Paint is recommended.

February 2014

Q. My hallway walls are covered with textured wallpaper that has been painted. I plan to paint over the paper because I believe the walls are uneven underneath. How should I prepare the walls before painting?

A. The walls need to be clean, you can use Resene Interior Paintwork Cleaner to clean them down. Given we do not know the brand or type of the existing paint I would recommend applying a coat of Resene Quick Dry waterborne primer undercoat and then apply two coats of Resene SpaceCote Low Sheen. Resene SpaceCote Low Sheen is a waterborne enamel paint and when cured will provide a more durable finish for hallways than paints like Resene Zylone Sheen which are formulated using conventional acrylic resin technology.

February 2014

Q. Can Resene Non-Skid Deck & Path be applied to a fibreglass type substrate?

A. Degrease the fibreglass and lightly sand taking care not to unduly scratch the surface then apply Resene Quick Dry waterborne primer undercoat and then follow with two coats of Resene Non-Skid Deck and Path. The aggregate is a marble type of a selected size range and if the substrate is sufficiently hard to resist impact damage when the coating is pressed then the aggregate will have no effect.

February 2014

Q. Do you have a marine grade clear coat for use on a galv raiing substrate?

A. The specification of clear coats over exterior galvanising is not recommend as corrosion of the galvanising can still occur and this has can cause the clear film to delaminate and there will be white corrosion salts visible at the clear/galvanising interface. For the protection of exterior galvanising with pigmented coatings, see Resene specification sheet 23.

February 2014

Q. Can anyone please tell me the best product/s to use to waterproof and seal a 6 x 4 metre wooden cabin?

A. Assuming this is a habitable cabin then the structure should inherently be weathertight and not rely on the applied paint to achieve weather tightness. The paint or stain then protects the surface, not waterproofs the entire structure. You could either stain the timber in Resene Waterborne Woodsman or if a painted finish is preferred then prime and then topcoat in Resene Lumbersider waterborne low sheen or Resene Sonyx 101 semi-gloss waterborne paint.

February 2014

Q. I have a 70s weatherboard home. The weatherboards are finished in Resene Lumbersider Ebony Clay tint. I wish to go to a semi-gloss white. How should I ensure that there is no bleed through of the dark colour so that the white topcoat is true white?

A. You should achieve hiding with two coats applied at the recommended spreading rate but if you have concerns then apply a coat of Resene Quick Dry waterborne primer undercoat prior to the two coats of Resene Sonyx 101 white.

February 2014

Q. I want to repaint my room white. However the existing colour is pink. From what I know this will make the white look pink. Is there anything I can do about this? The pink is a medium shade.

A. Application of two coats of white at the correct spreading rates should achieve total opacity but if you want a belts and braces system then apply a coat of Resene Quick Dry waterborne primer undercoat before applying the two coats of white topcoat.

February 2014

Q. Is there any clear coating to go on a Totara outside table. I was recommended Resene Uracryl 403, three coats.

A. We do not recommend any of our clear systems for the coating of exterior timber exposed to full weathering. While we can add U.V. absorbers to the clear there will be inevitably U.V. passage through the clear film and this will degrade the timber surface and result in peeling of the clear from the timber.

February 2014

Q. I have a painted grey steel staircase and want to repaint it. What type of paint should I use (Resene Uracryl) and what colours can I paint it?

Also I have varnished wall panels, and want to repaint in a colour - what prep and paint type do I need to use here?

A. Do you know what the existing paint on the steel staircase is? If not can you check if the existing paint is softened or dissolves when subject to meths? This will tell us if the paint is a conventional acrylic paint. With the varnished areas you can apply Resene Waterborne Smooth Surface Sealer as an adhesion primer then overcoat with a range of paint systems.

February 2014

Q. We are getting quotes for painting the factory floor and would like some information on what to use, the process and cure time.

A. Our system for painting the floor would most likely be Resene Aquapoxy for Flooring applied with Resene ArmourBond used as a sealer. Resene Aquapoxy is available in a selected range of tinted colours and in two gloss levels, gloss or semi-gloss. The Resene Aquapoxyfor Flooring system does give slip resistance to a floor. If a smooth finish is required the SRG Additive is not added to the second coat. Diamond grinding of the floor is the standard floor prep prior to application of the Resene Aquapoxy system.

February 2014

Q.We're building a new home with new, probably pine, weatherboards and fibrolite soffit that I'm painting myself. How many coats required and what for each coat?

A. Factory applied primers can be of questionable quality even when new. Weathering any primer for any period of time is not beneficial. Resene strongly recommend that all factory primed timber and weathered quality primer primed timber is thoroughly sanded back to a sound substrate and re-primed with a full coat of Resene Wood Primer. The only exception is if the primer used was Resene True-Prime. This primer does not require re-priming before painting, for up to 6 weeks.

Preparation for painting: Treat areas of moss or mould infestation with Resene Moss & Mould Killer, diluted at the rate of 200 grams to 1 litre of clean water. Leave for up to 48 hours to achieve full kill. For heavy infestations more applications may be needed. Thoroughly wash down with a 25% solution of Resene Paint Prep and Housewash and water to remove all dirt, dust, grease, moss and mould residue, chalk, cobwebs and other contaminants. Rinse thoroughly with clean water. Allow to dry. Thoroughly sand (using P180 grit paper) to produce a smooth, sound surface and to reduce any sharp arrisses to a rounded profile. Wipe surface with a damp rag to remove dust. Apply a full primer coat of Resene Wood Primer. Take care to apply primer well into nail holes. Fill all nail holes, damaged or split timber with Resene EzyFill or similar product applied in accordance with the manufacturer’s instructions. Spot prime filler (after 24-hour dry) with Resene Wood Primer.

Painting: Apply two full coats of Resene Sonyx 101. A Legend 63-88mm brush is recommended. Allow to dry between coats.

For new Villaboard® HardiGroove™ fibrous cement sheet soffits - New fibre cement soffits should be installed as per the board manufacturer’s specifications. Where gaps between boards require filling Villastop, or a similar exterior grade plaster should be used in accordance with the manufacturer’s directions to achieve a uniform surface for painting over.

Preparation for painting: Thoroughly wet sand to remove any sharp edges on profile. Scrub down with a stiff brush to remove all loosely bound material and any contaminants. Allow to dry. Any cement based stopping should be sealed as soon as possible using Resene Limelock. Ensure all nail heads are flush with the surface. Spot prime nail heads with Resene Galvo Prime.

Painting: Apply a full coat of Resene Quick Dry waterborne primer undercoat. Apply two full coats of Resene Sonyx 101. Apply to dry between coats.

February 2014

Q. We want to paint our concrete roof tiles. Do you have a paint for this job?

A. Assuming the tiles are clean and sound the recommended system would be to saturate the tiles with Resene Sureseal then apply two coats of Resene Summit Roof. The success is wholly dependent upon the initial cleaning of the roof. From experience we woud also recommend that the cleaning includes a treatment for moss, mould and algae as well as lichen.

February 2014

Q. I am about to start painting a mural on a toilet block close to the sea. It is in the open so I need to know exactly which paint to use for a lasting result.

A. For the base colours use Resene Lumbersider, allow to dry for 48 hours then wash down with fresh water and allow to dry then apply three coats of Uracryl 402 UVS Clear. The Uracryl UVS Clear is an anti-graffiti coating which also provides extra weather and U.V. protection to the mural colours.

February 2014

Q. We want to paint our new pine weatherboards a dark colour (i.e. Resene Foundry). We are sanding the factory primer off and re-priming with a CoolColour™ primer. I have been told that 45% LVR is the limit for pine boards but does this change if we use CoolColours? Can you tell us/forward the LVR for colours like Resene Foundry and if we can use them?

A. The LRV (light reflectance value) of a hot and cool version of a colour is the same as LRV has no relationship to heat reflected from a coloured surface. We use TSR (Total Solar Reflectance) measurements to show the increase in heat reflection of a CoolColour compared to the same colour made using non CoolColour technology. The advent of instrumentation to measure TSR is relatively recent and for this reason the timber weatherboard suppliers have used the LRV of colours to ensure that dark colours are not used for painting timber weatherboards. Dark colours reflect less heat (infra-red radiation) and can cause dimensional changes to the boards. The colour Resene Foundry has an LRV of 8, the TSR of the hot (non CoolColour) is 7.4 increasing to 26.4 for the CoolColour version of the colour (TSR is measured on panels with two coats of the colour applied over a white basecoat). We can establish a relationship between LRV and TSR and have used this to obtain a supplier concession to use CoolColours when the LRV has been less than the value they state for guarantee purposes. However for an LRV cut-off of 45% the TSR of the Resene Foundry CoolColour must be equal to or greater than 40%. Unfortunately, although the CoolColour version of the colour does reflect significantly more heat, the TSR value is still below the 40% requirement.

February 2014

Q. Please advise on the best way to apply your Resene Enamacryl Metallic Aluminium.

A. Spray application of metallic will always give the best finish. See the back of the Resene Metallics chart for recommendations.

February 2014

Q. Can Resene Lumbersider be painted on H3.2 treated timber?

A. Yes, but if the timber is treated prime first with Resene Wood Primer to seal off the migration of treatment salts in the timber.

February 2014

Q. I have a quantity of Resene Summit Roof paint left over. Can I use this on 4mm marine plywood, without undercoating?

A. Resene Summit Roof is only self-priming to new galvanising and Zincalume; it can be used as a topcoat on primed timber.

February 2014

Q. Do you have any ‘reflective paints’ at all. I want to paint an outside brick wall so that it reflects maximum light onto the plants in front of it.

A. White paint with reflective road marking glass spheres would give the best outcome but application of the beads to a vertical surface is virtually impossible.

February 2014

Q. Do you need to use an undercoat or sealer when using the CoolColour system?

A. Resene CoolColour™ technology will give some CoolColour benefits without the need to use CoolColour primers/undercoats. However to achieve the maximum CoolColour benefit application over a CoolColour primer or white undercoat is recommended.

February 2014

Q. What is the best product for rusty steel deck supports?

A. Maintenance of the integrity of the deck structure is a key safety issue and our first recommendation would be to seek advice from a professional engineer before looking to undertake painting to address corrosion.

February 2014

Q. I am looking to finish a pressed tin product with a powdercoat to make it resemble the attached image for a kitchen backsplash.

A. We do not supply powders to powder coating operations. Powdercoating requires a bake step and specialised powder application equipment. However if you want to paint the product then ensure the metal is degreased and apply a coat of Resene Armourcote 221 followed by two coats of a Resene Uracryl 400 Series topcoat. We can match the Resene Uracryl finish to Resene colours (with the exception of metallics).

February 2014

Q. Which Resene product would be most suitable for re-staining interior Douglas fir ceiling beams? I've been told that the existing stain on the beams might be shellac. I'm hoping to darken the colour from the existing reddish brown to more of a blackbean colour.

A. Shellac is a film forming varnish and seals the timber surface which rules out staining unless the shellac is completely removed. If you are looking to darken the existing shellac varnish surface an alternative would be to clean down the beams using Resene Interior Paintwork Cleaner, sand lightly to profile then apply Resene Aquaclear with added Resene Colorwood Enhance.

February 2014

Q. If using magnetic paint, does it need to be away from where a child’s head is? Thinking of magnetic underlays and such, that anything with a magnetic field may have an effect on health?

A. There is no known health issue with low strength magnetic fields and the materials used in Resene Magnetic Magic are a mixture of iron metal (to attract magnets) and natural magnetite. At the level used in our product the magnetic field is only operating over several millimetres. Beyond that sort of distance the natural background magnetism is stronger so there is no need to be concerned.

February 2014

Q. Has there been some kind of ruling now that elastomeric (e.g. Resene X-200) paint is required on some or all plaster houses?

A. There is nothing new but to achieve masonry wall weather tightness to meet the requirements of CCANZ CP01:2014 a pigmented standard (Resene X-200) or elastomeric (Resene Flexicover) acrylic must be applied to achieve a minimum dry film thickness of 180 microns.

February 2014

Q. I am about to paint our corrugated iron roof. It is in reasonable condition and was last painted about 12 years ago in green. Part has faded and part is newer in green COLORSTEEL®. I want to paint it all in mid grey. Is it ok to spot prime or do I need to apply a full coat of Resene Galvo-One primer? If I don’t need to apply a full coating of primer can I use Resene Hi-Glo CoolColour™ on top of the existing surface?

A. Scrub down using Resene Paint Prep and Housewash, prepare flaked areas back to a sound edge using a 3M Rust and Paint Removal Disc then spot prime these areas with Resene Galvo-One primer and follow this with two coats of Resene Summit Roof CoolColour™ version of the colour.

February 2014

Q. We have a house that has a big purpose built wooden deck going into the house from a concrete driveway. Because of the gradient the concrete could not be taken to the garage. Over the years the deck has become slippery when driving from the deck to the start of the concrete drive. We spray it on a regular basis so there is no mould. What’s a good product to use? Is there a rubber like paint, or adhesive we can apply?

A. The only option we have to increase wet slip resistance would be to apply Resene Non-Skid Deck & Path. We have no non slip clear for exterior application to timber surfaces. Before making any recommendation for painting the deck we would need to establish what the deck timber is and its condition.

February 2014

Q. I want to stain a bare basewood guitar body. Is the Resene Colorwood range suitable for this? Will I need a pre-stain, stain and polyurethane coating?

A. Solventbased non grain raising stains are usually used for staining instruments. Resene Colorwood could be used but the water based formulation may affect the structure of the guitar body.

February 2014

Q. Does Resene Moss & Mould Killer affect Butynol roofing?

A. At the usual dilution rates for the product there are no known effects upon Butynol. There will be a white residue left if the product dries on the surface but this should rinse off with water.

March 2014

Q. I am wondering if you have any paint that I could use to paint over ceramic tiles on a fireplace that does not get used - it is there for cosmetic reasons - but just really ugly?

A. Ensure the tiles are clean and free from grease/oil and then apply Resene Waterborne Smooth Surface Sealer and leave to cure for 48 hours then apply a coat of Resene Quick Dry waterborne primer undercoat and follow this with two coats of a Resene waterborne enamel topcoat. The system will take at least five days to develop adhesion.

March 2014

Q. We have a house which was built in 1960s. We have stripped wallpaper from a bedroom and were left with walls that were pretty unsightly - marks and dents etc. We have filled, sanded, and put a coat of Resene Broadwall Surface Prep & Seal. The question we have is, do we now need to apply a layer of pigmented sealer before we paint? One person has told us this is absolutely necessary as the paint will 'soak' into the broadwall. One person said paint on top of the broadwall is fine.

A. For non-wet areas you can apply a Resene wall paint directly to the Resene Broadwall Surface Prep & Seal.

March 2014

Q. When painting our bathroom I was advised to use an oil based enamel paint to protect against moisture. There seems to be very little oil based products available. What are the advantages in using an oil based enamel paint to using a waterborne enamel paint please?

A. Traditional solventborne enamels do have a lower moisture vapour transmission value than waterborne enamels and this is possibly why the recommendation to use these was given to you. However waterborne enamels (not conventional waterborne paints) are routinely used for painting bathrooms and kitchens as long as they are applied over a suitably prepared and primed substrate. Waterborne enamels if not fully cured before exposure to steam can have surfactant leaching (this can be overcome by leaving the new waterborne enamel to cure with good ventilation and heat) and this may also be a reason why you were advised to use a solventborne enamel. Resene has a full range of solventborne enamels: Resene Super Gloss (full gloss), Resene Lusta-Glo (semi-gloss), Resene Room Velvet (low sheen) and Resene Celling Velvet (flat). There are colour limitations for the last two products. Resene also has a full range of waterborne enamels.

March 2014

Q. What is the difference between water proof and water resistant paint?

A. The terms are often used loosely. However, from the CCANZ CP 01 2014 the following definitions are given: Waterproof the complete and total resistance of a building membrane to the ingress of any water in either the liquid or vapour state. Waterproof Membrane A membrane impervious to water which is placed to prevent the passage of water and water vapour through a concrete or concrete masonry element. Weather tightness: Term used to describe the resistance of a building to the weather. Weather tightness is a state where water is prevented from entering and accumulating behind the cladding in amounts that can cause undue dampness or damage to the building elements. Weather tight coating: A multi coat applied coating system applied to exterior walls to make them weather tight.

March 2014

Q. I have an outdoor pizza oven and the paint over the dome (concrete) is bubbling and peeling – must be due to expansion and contraction – what paint should I be using? Is there such a thing as stretchy paint?

A. The issue is not necessarily the paint type used but it will be the heat resistance of the paint - that is the surface temperatures are above what the paint can accommodate.

The best system that I have found for this application is Resene Armourcote 221 and two coats of Resene Uracryl. If the surface is too hot to have hand contact when in full use then it cannot be painted. If it is cool enough for hand contact and you decide to reprint, then all of the existing paint will have to be completely removed first.polyurethaned rimu I'm wanting to paint timber stairs that are polyurethaned rimu. Should I use a sealer before painting?

A. In this situation you would need to ensure that the old varnish was clean and then thoroughly sanded as a start point. Sanding does not need to be back to bare timber but the varnish but needs to be sanded to give a profile for the new paint.

March 2014

Q. I have managed to rip a hole on my wall while trying to remove one of those stick on hooks. The paper has come away from the plasterboard. The wall is lined with lining paper and then painted with Resene Double Ash.

A. It is best to repair this with a stopping compound like Plus 4. Apply this to the damaged areas with a broad flat spatula allow to dry then sand smooth, hopefully you will need only a single application. Then seal the sanded area with Resene Sureseal and you can then apply standard Resene wall paints.

March 2014

Q. I have external concrete blocks to paint and am unsure if the existing paint is water or oil based. Can I put water based acrylic on top?

A. Best to test the existing paint with meths and a cloth. Wash down a small area, allow to dry then, with a cloth soaked in meths, rub the cleaned area and see if the paint softens or dissolves. This will indicate a waterborne paint.

March 2014

Q. I have a new house with concrete block walls. These will be bare (unplastered) on the exterior. We will paint these for waterproofing, so are looking at Resene X-200 for this. My question is whether there is any need to use Resene Limelock or any other product as a basecoat. Two specific considerations - (1) there is some lime staining visible on the wall at present, (2) some of the lower part of the wall runs below floor slab level, so has hardfill and soil behind it.

A. Resene X-200 is only suitable for use above ground level, in your case apply a coat of Resene Sureseal before applying the three coats of Resene X-200.

March 2014

Q. I have a question for your experts about old homes and white paint. Why does it change to an off white over the years? If you want a lasting white shade, which white could you suggest? Please also state if it is available in enamel as I prefer to enamel door, window frames and architraves.

A. The yellowing of alkyd paints occurs as a result of photochemical reaction of the natural vegetable oils that are used to produce the alkyd resins that are used to produce the paints. The yellowing occurs in darkened areas such as the inside of cupboards and pocket doors (doors that slide into a wall cavity). Yellowing also occurs when the paint films are cleaned with ammonia based cleaners. Waterborne enamel paints are not prone to film yellowing. Most customers now use waterborne enamels such as Resene Lustacryl on their doors and trim.

March 2014

Q. We are wanting to paint our new pine weatherboards a dark colour – Resene Foundry. We are sanding the factory primer off and repriming with a white primer. I have been told that 45% LVR is the limit for pine boards but does this change if we use CoolColour™?

A. The LRV (light reflectance value) of a hot and cool version of a colour is the same as the LRV has no relationship to heat reflected from a coloured surface. We use TSR (Total Solar Reflectance) measurements to show the increase in heat reflection of a CoolColour compared to the same colour made using non CoolColour technology.

The advent of instrumentation to measure TSR is relatively recent and for this reason the timber weatherboard suppliers have used the LRV of colours to ensure that dark colours are not used for painting timber weatherboards. Dark colours reflect less heat (infra-red radiation) and can cause dimensional changes to the boards. The colour Resene Foundry has an LRV of 8, the TSR of the hot (non cool colour) is 7.4 increasing to 26.4 for the cooler version of the colour (TSR is measured on panels with 2 coats of the colour applied over a white basecoat). We can establish a relationship between LRV and TSR and have used this to obtain a supplier concession to use CoolColours for many colours.

However for an LRV cut-off of 45% the TSR of the Resene Foundry CoolColour must equal to or greater than a colour with a LRV of 45%.

March 2014

Q. How do I find out the LRV (light reflectance value) for wood stains?

A. Wood stains don’t have LRV as they are semi-transparent. LRV is only used for solid finishes.

March 2014

Q. Can you use Resene Magnetic Magic under Resene Blackboard Paint?

A. Yes you can use Resene Magnetic Magic under Resene Blackboard Paint. The main thing is to make sure the Resene Magnetic Magic is applied in nice thick coats and check it is working well with your magnets before topcoating.

March 2014

Q. I have a shed which has a plywood roof and walls. I want to waterproof the plywood roof. Have you suggestions on which paint I could use?

A. Prime with two coats of Resene Quick Dry waterborne primer undercoat then apply coats of Resene Sonyx 101 in your selected colour. This system will give weather proofing but not waterproofing.

Q. Do you have a paint I can use on a 650g/M2 blackout PVC-coated polyester textile, basically on an outside marquee wall?

A. Our standard exterior acrylics have excellent adhesion to uPVC, however you can experience two issues. The first is that the acrylics don’t have block resistance when means that if two painted surfaces touch then they will fuse. Secondly given the use of the material the PVC may well have plasticisers at a high level and if present these will migrate into the paint and this will make the paint permanently tacky.

April 2014

Q. Is it acceptable to paint over wallpaper? If so, what sealer is recommended please?

A. Wallpaper can be painted over; the paper may need to be sealed first before applying a waterborne paint finish. Resene Vinyl Wallpaper Sealer is required when painting over a vinyl paper or Resene Sureseal if painting over a paper that has yellowed or has a metal flake in the paper.

You can test the need for a sealer by painting a small area with a Resene testpot, leave for 48 hours and check the paint for tackiness. If there is no surface tack then you may be able to apply the waterborne paints directly without sealing the paper first. Some surface tackiness may take longer to show.

April 2014

Q. What would you recommend doing with wallpaper corners that are lifting slightly please?

A. We sell Wallpaper Stick Down Adhesive for re-attaching detached areas.

April 2014

Q. I have chosen Resene Glitterbug metallic for a feature Gyprock® column in an office. Painter is requesting application method.

A. There are application details on the Metallics colour chart; for non flat surfaces we would definitely recommend spray application to achieve a uniform finish.

April 2014

Q. I need some general advice on preparation for painting interior walls – where’s the best place to look for it?

A. The Resene popular paint systems brochure covers off the most common surfaces. You might find this online information about paintinginterior walls helpful.

It covers off various interior areas in more detail. If you find you still need information it’s best to talk through your project with our Resene ColorShop staff who can discuss all the steps you need to follow or you can email any specific questions to our Technical Expert to reply to – you can email them via our online form.

April 2014

Q. What is the difference between waterbased and solventbased paint? Advantages and disadvantages.

A. The main differences between waterborne and solventborne are covered on our website – click here to view.

April 2014

Q. We are painting a new bedroom in Resene Half Tea and wonder whether we use the same flat acrylic paint on the door and wardrobe doors or should we use the semi-gloss waterborne enamel. Skirtings and architraves are in white.

A. Normally walls are finished in a low sheen or flat finish (such as Resene Zylone Sheen or Resene SpaceCote Low Sheen or Flat) and generally we recommend doors, trim and joinery are finished in semi-gloss - like Resene Lustacryl. The semi-gloss finish is easier to wipe clean than a lower sheen finish.

April 2014

Q. I am trying to figure out what colour my garage door is painted, as I am looking to repaint it. I have no idea of the colour or brand of paint used.

A. All paints will fade when painted outside so it may be that the original colour was darker than it is now. If you want an exact colour match to the current colour the best idea is to bring in a piece of the colour (scrape off a piece of colour) and bring it into a Resene ColorShop and they can colour match it for you.

April 2014

Q. Our house is painted with Resene paints and unfortunately I placed an automatic fly spray too close to the ceiling resulting in a stain on the ceiling. Any suggestions on how to remove it prior to repainting?

A. The affected area will need to be wiped down with a rag wetted with mineral turps, repeat this with a new rag at least three times. Allow the area to dry then seal off with two coats of Resene Sureseal before repainting.

April 2014

Q. I have a can of Resene X-200 acrylic weathertight membrane which I have just opened and stirred. The paint appears very grainy? Is this normal?

A. X-200 does contain a fibre reinforcement and this may be what you are interpreting as grainy.

April 2014

Q. Please tell me the correct undercoat/sealer to use in a new bathroom. I am painting over new freshly plastered villa board and plasterboard.

A. Resene Sureseal is the recommended sealer for sealing new stopped plasterboard in wet areas.

April 2014

Q. Is it possible to paint ceramic floor tiles? They are on the base a freestanding wood fire is on.

A. It is possible but if embers or the like fall onto the paint the paint will immediately be damaged.

April 2014

Q. What’s the best paint for a fence? I don’t want a fence paint that doesn’t last.

A. If you are talking about new fencing then for timber fencing Resene Lumbersider is the product to use. For best performance it is best applied over a primed surface and opt for the Resene CoolColour™ version of the colour if available.

April 2014

Q. Can you please advise me if there is a paint that is best to use when painting over wallpaper? One which may have a thicker consistency to hide imperfections perhaps.

A. There is no easy answer to your question, it really depends upon the imperfections that you are trying to hide. Two coats of Resene Broadwall Surface Prep and Seal will fill minor surface imperfections and then you can overcoat with a wall paint such as Resene Zylone Sheen. Would advise that you fill the most obvious imperfections first.

April 2014

Q. Do you paint the top surface of doors?

A. The standard for painting does state that the top and bottom edges of doors are to be painted as this reduces moisture uptake from these edges. It used to be standard trade practice but seems to have become less common.

April 2014

Q. I need to repaint granite headstones with White and Gold lettering - what paint do you recommend?

A. Remove all dirt and loose material from the lettering areas to be coated. Use Resene Lumbersider White and Resene Enamacryl Metallic Gold.

April 2014

Q. I am painting wooden cladding on the outside of a house. It was only painted last year and a lot of the paint has bubbled. I am using barn paint - why does it keep bubbling?

A. Here we do not sell paint branded as barn paint but I would assume that the paint you have is more than likely waterborne. We have a general rule when dealing with blistering paint. Does the blister contain liquid? Also cut a blister open and check the colour on the reverse of the blister - if this is the same as the topcoat colour then the issue is intercoat adhesion of the new to old paint and this is normally due to surface preparation prior to application of the new paint. If the reverse colour is different then this is due to failure of an underlying paint layer and arises most often when multiple coats of paint have been applied over many years. Paint will always fail at the weakest point.

April 2014

Q. We have a new concrete block and timber palling fence. Is there a paint product that can be used on both surfaces? The contractor will be using a sprayer, I think.

A. Resene Lumbersider can be used as the topcoat for both substrates. Concrete will have to be free of form oils/release agents/dirt/ dust and other contaminants, likewise for the timber palings. For best results we would suggest priming the concrete with Resene Concrete Primer and the timber with Resene Quick Dry waterborne primer undercoat.

April 2014

Q. Can you please confirm which clear coating (polyurethane) product I can use in a wet area that will comply with AS/NZS 4858 or has an equivalent BRANZ appraisal? I am using a timber flooring product in wet area zones and the timber product requires that this condition is met. I have read through some of your data sheets but have not found this information.

A. We have no test data for a Resene clear for this application but we have for many years specified four coats of Resene Polythane for application to timber in wet areas.

April 2014

Q. I want to spray Resene Uracryl 402 on custom wood furniture. What primer and undercoat is recommended? I am told the primer needs to be a cross linking acrylic primer - which of your products is that?

A. In this case you can spray apply Resene Armourcote 220 as the basecoat. While it is a metal primer it can be used for your application.

April 2014

Q. A house I have been asked to look at has had its interior door and window frames sealed with waterborne enamel and topcoated with two coats of oil so no sealer/undercoats have been used. It was painted about 6 months ago. What can I do to fix or will it be ok? What will happen to these surfaces in the longer term because of this?

A. I assume by oil you mean an oil based enamel topcoat. There should be no real issue of adhesion of the oil based topcoat to the waterborne enamel basecoat as long as there was only a short interval between the applications. For internal timber we recommend application of a dedicated wood primer or enamel undercoat before top coating. It’s difficult to make any comments on long term issues without more detail on where the substrates are located within the house, the specific products used and whether it was a repaint or new work.

April 2014

Q. Can acrylic water based paint be used over old epoxy oil based paint on a swimming pool deck?

A. Scrub down with Resene Paint Prep and Hosusewash, rinse off and allow to dry then thoroughly sand with 120 grit sandpaper, dust off and prime with Resene Quick Dry waterborne primer undercoat. Then apply two coats of Resene Lumbersider. If you want to achieve extra slip resistance add Resene SRG Grit (added at 500 grams per litre) to the first coat of Resene Lumbersider.

April 2014

Q. Do you have a paint that stops plastiser migration from PVC?

A. We use our water borne exterior acrylic paints to paint uPVC without any issues arising due to plasticiser migration.

April 2014

Q. I am adding a bedroom to an existing (4 year old) cedar home. The current building is waterbased stained and has faded quite a lot and needs restaining. Should I use prestained cedar cladding on the new extension and then stain the rest of the house, or is it better to wait until the new timber has gone silver/grey and then stain the lot?

A. Allowing cedar to weather will allow mould growth to occur, this is avoided if the cedar to stained as soon as possible after installation. There may always be a colour difference between the old and new sections even if they are stained unless you are using dark coloured stains.

April 2014

Q. I have stripped the top layer of vinyl wallpaper off and found that underneath the wallpaper is a layer of paint and then another layer of wallpaper. Is it possible to just paint over the paper backing of the first layer of wallpaper? If so, what should I do to prepare the wall? If not, what is the best way to remove all the layers?

A. You can paint over the backing layer but you first need to seal it with Resene Sureseal then apply a coat of Resene Boardwall Surface Prep and Seal.

April 2014

Q. We have bought a house with concrete water tanks and are on tank water. Can we paint the outside of these tanks as they look horrible coming up our driveway?

A. Yes, as long as there is no seepage or leaks.

April 2014

Q. Our house exterior was painted with Resene X-200 about six weeks ago and we are now seeing what appear to be bubbles on the exterior surface. We have advised the painters who did the work and they are coming back soon to have a look. Is this a fixable thing?

A. This is not the norm following application of Resene X-200. We suggest that you cut a blister and see if it contains liquid and check the colour on the underside of the blister. If the underside colour is the same as the top then this usually suggests an issue with prep. If the colour on the back is different from the top this may indicate failure of a paint layer associated with a previous repaint.

April 2014

Q. We had some mould on our 'cottage cheese'/textured plaster sleeping room ceiling. Three weeks ago our landlord sent somebody to clean the ceiling with a ‘secret chemical’ and since then there is a persistent odour in the sleeping room that made us sleep in the lounge. We would now like to do some DIY and seal the ceiling surface with something that also blocks odour.

A. I am not aware of any paint coating that could be used to seal in the odour, especiailly as you cannot identify what the chemical that was used. I suggest getting as much ventilation into the room as possible and washing the ceiling down with water and detergent.

May 2014

Q. I am presently renovating my house. Our downstairs bathroom has terracotta floor tiles and white wall tiles. The top wall tile has a ‘dated’ pattern incorporated on it which I would like to change. For a tiler to remove the top tile right around the bathroom is costly And could damage the plasterboard. Could you recommend a suitable paint that we could use over the listello glazed tile which is only about 45mm in height and something that would give a nice modern effect?

A. The only system we would suggest is that you apply Resene Waterborne Smooth Surface Sealer to the degreased tiles and leave to cure for 48 hours, then undercoat with Resene Quick Dry waterborne primer undercoat and finish with two coats of a Resene waterborne enamel such as Resene Lustacryl Kitchen & Bathroom. Ensure that the new paint is not subject to steam or water contact for at least 48 hours after completion of painting.

May 2014

Q. We are planning to paint our new pine weatherboards with Resene Double Napa exterior water based paint. Are there any changes to the paint likely due to weather and/or sun? What life can we expect if we use sealer undercoat and two topcoats?

A. If the weatherboards are primed they will need to be thoroughly sanded and reprimed with Resene Wood Primer before application of the topcoats. Given the colour you are planning to use I would strongly suggest that you use the CoolColour™ version of the colour. The LRV of your colour is 30% which is well below the LRV cut off of 40% that most weatherboard suppliers place on colour to get their guarantee.

May 2014

Q. What kind of paint finish do I use on interior walls, i.e. low sheen etc?

A. The finish most used is low sheen. Resene has two interior low sheen wall finishes, Resene Zylone Sheen and Resene SpaceCote Low Sheen. The Resene SpaceCote Low Sheen is a tougher finish and is best used for areas subject to extra wear.

May 2014

Q. I want to paint our COLORSTEEL® a light colour to give it some slight texture. Should I use Resene AquaShield or something else?

A. COLORSTEEL® that has been exposed to direct weathering for at least 4 weeks and is sound can be overcoated with Resene Hi-Glo or Resene Summit Roof Paint. Scrub down with Resene Paint Prep and Housewash, rinse clean with water allow to dry and apply two coats of either of the products. For a textured effect, apply Resene Galvo One then spray apply Resene Resitex.

May 2014

Q. I wish to paint the back of a glass lazy susan that I have mosaiced to stop the glue showing through. I need a permanent glass paint. Which would you recommend?

A. For this you could use two coats of Resene Super Gloss enamel.

May 2014

Q. Can Resene Blacktop be applied to a near new concrete drive - there is a hairline crack approx 1mm wide needs covering?

A. Resene Blacktop has been formulated for application to a bituminous substrate. It has been used with varying degrees of success over a concrete substrate. In your case the concrete cracking and size of the cracks may be made worse by application of the coating as the black colour will attract more heat.

May 2014

Q. A small part of my house is monolithic. It is the end of the house (an extension). The three sides of the monolithic extension face south, south east and west. I noticed on your website that monolithic cladding should be painted light colours to avoid contraction and expansion in the heat and therefore weathertightness issues. You state a LRV of at least 40. We have selected Resene Half Pravda as the colour for the rest of the house. This has an LRV of 39. Do you think that is ok?

A. The LRV of 39 is very similar to the 40 cut-off and I would say that the application of the colour should not create issues; however to give an increased level of confidence I would recommend you use the CoolColour™ version of the colour.

May 2014

Q. Our painter accidentally splashed some white Resene Lustacryl paint onto some brand new shiny black plastic electrical insulation that sheaths the mains electricity wires coming into our house. The paint has now dried. What solvent can we use to remove it, or if it can't be removed, what type of black paint should we apply to cover it up?

A. Meths is the usual solvent for softening waterborne paints but this needs to be done within 24 hours to be really effective. You can try using a cloth wet with meths and rub the paint and see if it can be removed. If not then you can use any Resene waterborne paint to paint over the white, you can purchase a Resene testpot of black if you only have small areas to overcoat.

May 2014

Q. Is there any product that would remove burn marks in spotted gum decking caused by sparks from an angle grinder being used overhead? Something that might bleach them out as opposed to sanding.

A. Sorry not aware of any magical potion other than sanding.

May 2014

Q. I have Resene oil-based soft sheen on the wooden doors in my house. Have now painted them with Resene SpaceCote Low Sheen waterborne enamel. Big problem is that paint is just scratching off with my fingernail after 3 days.

A. To ensure adhesion of a new coating over old or well cured enamels, the surface needs to be thoroughly sanded before recoating and then undercoated with Resene Quick Dry waterborne primer undercoat before application of the Resene waterborne enamel finish.

Most doors are generally finished in a semi-gloss finish.

May 2014

Q. We have a pink slightly embossed pattern laminate (Seratone) lined shower. It is in good condition with the only issue being the colour. I have heard indirectly it is possible to paint this but I am concerned about the durability of the paint and the possible gloss level achievable to allow future ease of cleaning. Is it possible to successfully paint this type of surface in such a demanding application?

A. The Seratone can be painted but the painted surface will not replicate the properties of the original lining. There will always be the chance of paint delamination as well. Unfortunately we cannot guarantee adhesion for this situation.

May 2014

Always make sure you read the product label and data sheet prior to application. If in doubt about any aspect of your project, please ask our Technical Expert for help or come in and see our staff at your local Resene ColorShop or Reseller.
