Q. I have a 28 year old COLORSTEEL® roof with puzzling blistering on the third from right flat part of profile. This is only on a few sheets all the rest are ok. However advice on how to treat this, also rest of roof and which of your products to use would be appreciated to paint whole roof. The roof is original COLORSTEEL® Karaka, never been painted or chemically cleaned and we are many miles from the ocean. There is no overhanging vegetation, and the area affected us well away from our chimney.  The entire sheet is affected.

A. It is unusual to see only a few sheets affected on a particular location. Given the age of the roof the original coating system has performed well. Is there any fallout form a chimney that may explain the blistering or over hanging vegetation?

The zinc present on galvanised or Zincalume roofing is sacrificial, the zinc oxidises and this electro-chemical reaction protects the underlying in steel from corrosion. White rust is the by-product of the zinc reacting with the atmosphere eventually the zinc is totally consumed and then the steel begins to rust and red rusting is seen. The rate of reaction is determined by the atmospheric conditions and salt that falls onto the roofing.

While the white material you see on the one roof section may well be white corrosion it is not usually confined to such a well-defined section of the roofing.

Suggest that you look to undertake a total strip of the affected section to see if there is under film corrosion present. If this is the case then you can apply a paint system to extend the life of the base material.

White rust forms when zinc is in an environment with hydrogen and oxygen. Most frequently, it occurs when a freshly galvanised material is placed into contact with water. White rust is especially likely to form on newly galvanised material. This is because the new zinc coating has not yet had the chance to form the stable oxides, and the hydrogen and the oxygen bond with the pure zinc which forms zinc hydroxide. White rust can be common on galvanised sheet that is being stored, as condensation can become trapped between the individual sheets, leading to the formation of white rust.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.    

All paint that is flaking or unsound must be removed by using mechanical methods (3M Rust and Paint Removal Disc), chemical stripper or high pressure waterblasting taking care not to damage either the substrate or the surrounding areas.

For the stripped section, after stripping remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note:  The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

Prime bare substrates with two coats of Resene GP Metal Primer then apply two coats of Resene Summit Roof.

Q. I want to repaint my 6yr old townhouse which has Linea® boards painted in Ironsand.  The north facing side has faded quite a lot and has a matt finish to it.  I am unsure of what has been used previously.  I would like to paint as much of it as I can myself and have seen that you recommend Resene Sonyx 101 for Linea® board but when I went to the Resene ColorShop I was not sure of whether to get that or the Resene Lumbersider paint (which I used on the fence).  Are you able to advise and is the Resene Sonyx 101 easy to paint with (similar to the Resene Lumbersider paint)?  I do also have a few joins in the Linea® boards that show at the moment as well.

A. Resene Sonyx 101 is a semi-gloss finish whereas Resene Lumbersider is a low sheen finish, both waterborne exterior paints. Both products are easy to apply.

While Resene Sonyx 101 will give a longer time to the onset of chalking the higher gloss level does highlight surface imperfections more than a lower sheen finish and for this reason many choose to use Resene Lumbersider.

The existing dark colour will cause filled joints to expand and contract with changes in sun intensity. While application of the Resene CoolColour™ version of a dark colour will increase heat reflection the CoolColour does not result in a surface cool to touch so joint expansion will still occur.

Q. I am looking to revive the outside of a stucco clad house. After making some repairs I'm looking for a very thick paint which will hide any minor flaws as well as be good future protection. Do you have such paint?

A. We recommend Resene X-200.

September 2019

Q. What paint do I need to use to paint my concrete garage floor and what do I need to do to prepare it to obtain a lasting paint job?

A. Degrease using Resene Heavy Duty Paint Cleaner and Oil Remover diluted and used to label instructions. Diamond grind to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

Apply a seal coat of Resene ArmourBond and finish with the Resene Aquapoxy for Flooring system.

September 2019

Q. I am looking for a child-safe stain for wooden blocks in brilliant colours.

A. We recommend Resene Colorwood.

September 2019

Q. I wish to waterproof the exterior cladding on my garden shed, which is clad with cement board. I'm after a clear finish; otherwise I would just paint it. I'm looking at your Resene Aquapel. Does this fit the bill?

A. Resene Aquapel is a water repellent treatment only, will not render the surface watertight. It would be better to paint with a solid paint system such as Resene X-200.

September 2019

Q. I want to paint my weatherboard house and I want to prep it correctly. It currently has primer and two acrylic topcoats, which are flaking off to bare wood (done 25 years ago!). I plan to scrape the paint off, but understand it is best not to electric sand acrylic off as the acrylic heats and balls. How do I remove the paint once the scraper has done its job (I wish to avoid mapping)?

A. It may be time to consider a total strip; areas that appear sound may also flake when more paint is applied.

Wet sanding is used to avoid balling up of waterborne paint. To address mapping you can use Resene Timber Surface Prep.

September 2019

Q. We have removed wallpaper that was directly glued to the GIB®. It has been removed quite well but we need to do some repairs with GIB® Tradeset compound. Do we use the compound first, directly onto the GIB® and then seal with Resene Broadwall Surface Prep and Seal or after and then spot seal again with the Resene Broadwall?

A. You can do the plastering direct to bare GIB®, and then apply the Resene Broadwall Surface Prep & Seal.

September 2019

Q. We have rebuilt a house from the studs up. We want to paint all the ceilings, windows and doors white, and the walls and trims in a concrete colour. Everything will need sealing/priming first. What paint products do you suggest? Is there one product that will do everything? Children will be living in the house once completed, so finishes need to be hard wearing and cleanable.

A. We recommend Resene SpaceCote Low Sheen and for wet areas, Resene SpaceCote Low Sheen Kitchen & Bathroom applied over the appropriate substrate priming system.

September 2019

Q. I need to seal a particle board floor, prior to carpet being laid.  Information about your product, Resene Particle Board Sealer, indicates that this product must be overcoated - is this still a requirement if the floor is to be carpeted?

A. Resene Particle Board sealer has been replaced with Resene AquaLAQ Quick Dry Sealer. If the sealed surface is to be carpet covered, then it should not need to be overcoated. I would stay away from carpet glue however, as we have not looked at this application for the product.

September 2019

Q. Can Resene Enamacryl be mixed with Resene Lustacryl?

A. Sorry but no, as the products are based on different resin systems.

September 2019

Q. I have a new fence which is made from treated timber and I wish to paint it off-white. Would Resene Lumbersider be the right choice for this job? Will yellowing from knots in the wood show through?

A. Resene Lumbersider can be used direct to new timber; resin exudation is the main issue with fence palings. It is usually less likely to be an issue with white but can still occur.

Application of a coat of Resene Wood Primer will assist with this and also block any treatment staining. However, it is difficult to predict what the outcome of not using the primer would be.

September 2019

Q. I want to re-purpose a stained, solid wood set of drawers to go into a bathroom. What prep and undercoat do I use to waterproof them before I paint and, what topcoat would be best?

A. Using Resene Interior Paintwork Cleaner, ensure the surfaces to be painted are clean and free from grease, and pay particular attention to hand contact areas and then thoroughly sand to profile for painting. Dust off and apply a full coat of Resene Quick Dry primer undercoat and finish with two coats of Resene Lustacryl.

We cannot guarantee that there will be no colour bleed from the existing stain, if you see bleed after applying the Resene Quick Dry; apply a seal coat of Resene StainLock before topcoating.

September 2019

Q. My engineer letter states to use an inorganic Zinc Silicate Primer to a dry film thickness of 75 microns as per AS/NZS2312:2002. This is for paint for my steel brackets on my deck. Do you have a paint that conforms?

A. Yes, we recommend Resene Zincilate 11.

Note that the primer must be applied over steel abrasive, blasted to near white metal and before the blast level is lost. It's not recommended for a DIY project.

September 2019

Q. We have interior concrete floors that have been painted a multitude of colours over quite a few years, before we moved here.  One load of paint is epoxy covered, with a vinyl paint in some places that peels off when it gets wet. Some parts are bare.

Tomorrow we are getting a concrete grinder in to remove all the paint so we can start afresh. What do you recommend we use to repaint? It is garaging for two cars which go in and out reasonably frequently.

A. We recommend Resene Aquapoxy for Flooring.

September 2019

Q. Is it okay to do exterior painting at this time of year? I have heard in the past that it can be too cold and affects the quality and durability of the finish.

A. There are three factors that affect the drying of waterborne paint, air temperature, humidity and air flow.

While it can be difficult to easily assess, if painting is possible we have recently launched Resene Wintergrade Additive which extends the possible painting window to achieve application over the colder months of the year.

September 2019

Q. I have moved into a new house and the painter hasn't sealed the MDF board in the bathroom and water has got into the board. I am going to replace it and we have leftover paint from the build. What should I use in the bathroom on the door and skirting? It will get wet from time to time from water under the shower door.

A. Prime the bare MDF with two coats of Resene Quick Dry then apply two coats of Resene Lustacryl topcoat.

September 2019

Q. I am a glass artist who cuts glass and makes collage glass wall hangings. I would like to know how to colour glass (like on a splashback), not onto toughened glass but normal glass so I can cut it with a glass cutter. I don't know how to spray, but if I could paint it on, in different colours that would be awesome. Colour would also need to last a long time and not fade.

A. When painting the reverse side of glass as is the case for splashbacks, the glass must be low iron. If you look side on at a piece of cut glass, you will see that is has a distinct green colour. This sees the colour viewed through the glass being very different from the back face colour.

Given that the colour is being applied to the reverse side of the glass, there should be no reason why the paint colour cannot be brushed with thinning.

September 2019

Q. I have a Honda 4X4 quad bike at the beach. It has light surface rust on the underside of the frame. I would like to try and give the bike a few more years of service life. It is a personal use of the bike, not commercial. Could you recommend a base coat and topcoat please? I am not really worried about how the final surface looks and prefer black.

A. Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure water-blasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish. Wet sand the sound paint, using 400 grit wet and dry to profile for re-coating.

Note: The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

Then prime bare areas with Resene Armourcote 221 and apply a full coat of the primer and finish with two coats of Resene Uracryl 403.

September 2019

Q. I have an open plan lounge, dining and kitchen area. The ceiling is currently painted with a flat white paint and is in need of refreshing. The ceiling is in very good condition as the house is only 10 years old. However, the log burner has caused the ceiling to go quite black with soot/smoke. I have tried washing it off but it just smudges it further. What ceiling paint would you recommend I use and would I need to put some kind of undercoat on to cover the black first?

A. Apply Resene Sureseal to areas of smoke damage, then apply waterborne ceiling paint, such as Resene SpaceCote Flat or Resene Ceiling Paint.

September 2019

Q. We had our home painted in 2008 and we need some touch up paint - the colour was Resene Double Blanc - do you still have anything like this or can you help?

A. Yes, the colour formulation still exists.  However, when touching up the gloss level of the original paint it is just as important as the colour. If this is an exterior touch up, there will be significant reduction in gloss loss level and (possible colour change due to the action of weathering). This often makes a seamless touch up not possible.

September 2019

Q. I like Resene Nocturnal and Resene Alabaster. Can these go outside or can you help with what we can use?

A. Yes, we do not have separate interior/exterior colours. If using Resene Nocturnal for exterior painting, we recommend using the Resene CoolColour™ version not the standard colour.

The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

September 2019

Q. I am about to paint a new house. The weatherboards are 50x25 H3.2 radiata pine from KLC/South Pacific Timber. What is the best undercoat for these?

A. Sand any sharp edges on timber profiles to a rounded edge. This particularly applies to scalloped weatherboards.

Ensure all surfaces are clean and free from contamination before painting. Thoroughly sand the factory primer and then apply a full coat of Resene Wood Primer followed by two coats of Resene Sonyx 101 topcoat. If selecting dark colours use the Resene CoolColour™ version of the topcoat colour.

The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

September 2019

Q. I am looking at staining some wooden toys and just wonder whether the wood interior stains would be appropriate. They are toys not designed to go in the mouth but with kids you never know.

A. Resene Colorwood is an Resene Environment Choice Approved product and will be suitable for staining wooden toys.  The stained timber is usually protected by application of Resene Aquaclear, which is also Environmental Choice approved.

September 2019

Q. I have replaced some cement panels on the exterior of our house - on the triangular end sections below the soffit above the weatherboards, what sealer/undercoat/finish products do you recommend?

A. Prime the new fibre cement with Resene Concrete Primer then apply two coats of Resene Sonyx 101 or Resene Lumbersider.

September 2019

Q. Can I seal a concrete floor and also put carpet down? If it's sealed and the carpet fitters glue down the underlay, will this affect the sealing?

A. Check using the water splash test, for the presence of a curing membrane, water splashed onto the concrete should immediately darken the concrete and be absorbed. If the water is not immediately absorbed and the wet concrete does not darken, then this indicates the presence of a curing membrane. If there is curing membrane present then diamond grind, to remove the curing membrane to achieve a uniform surface profile similar to 180 grit sand paper. Ensure all grinding dust is removed, this may require wet mopping.

Apply two coats of Resene HydraBlock epoxy coating at 10 square metres per litre per coat.

September 2019

Q. If I have got a musty smell out of my drawers, can I paint them to stop it coming back and if so, what paint do I use?

A. The musty smell is usually indicative of bacteria or mould being present.

Wipe the surfaces down with Resene Moss & Mould Killer diluted and used to label directions, then apply a full coat of Resene Quick Dry primer undercoat and finish with two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom.

September 2019

Q. I have a large Totalspan COLORSTEEL® shed 480 sq m which is about 15 years old. Is it possible to paint over the COLORSTEEL® to change the colour?

A. Wash down with Resene Roof and Metal Wash diluted and used to label directions to achieve a clean, chalk free surface. Then apply a full coat of Resene Pre-Coated Steel Primer and finish with two coats of Resene Summit Roof.

September 2019

Q. We have a conservatory area with polyurethane finished douglas fir rafters that have become water stained. What would be the best way to renovate these rafters so that the water stains are no longer visible? We would like to retain the natural timber finish if possible.

A. The only way is to strip the clear varnish back to bare timber then thoroughly sand to remove the water staining, or treat the bare stained areas with a 5% solution of oxalic acid, then sand.

However if you reapply a clear, the staining may reappear unless the water source that is generating the staining can be identified and blocked.

September 2019

Q. We have plastic glossy walls in our bathroom. Are there any paints in the Resene range that we could paint over this with?

A. The existing paint is probably solventborne enamel paint. To recoat these paints they require a clean and thorough sand to profile for recoating. Then apply a full coat of Resene Quick Dry primer undercoat. Then apply two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom.

Ensure good ventilation during painting and allow the new paint system to cure for at least three days with good ventilation before recommissioning the bathroom.

September 2019

Q. My bed has left a mark on the wall, which I then tried to scrub off but had no luck, so I tried to paint over it trying to match paint, also didn't work, so I tried to scrub that off and I've scrubbed off too much paint in areas and basically just made a mess of it.

I need some help with either matching paint to the wall or if worst comes to worst then repainting the room.

A. Assuming the existing wall paint is waterborne, lightly sand the area to be repaired with 240 grit sandpaper, dust off and spot prime with Resene Quick Dry then apply two coats of colour in the same gloss level as the existing paint (thin the portion of touch up paint with 10% water). Feather out to blend into the existing paint. If touching up using a different application tool to what was originally used then this can make the touch up more obvious.

September 2019

Q. Can you add Resene MoulDefender to decking stains?

A. There should be no need to, as the decking stain formulations contain mould inhibition additives. Resene MoulDefender is primarily focused for interior use.

September 2019

Q. Could you advise of the best materials/paints to prepare and paint an internal brick wall/wood burner surround?

A. Our criteria for painting in this situation is that you must be able to maintain hand contact on the areas to be painted when the fire is at full heat.

If this is the case then apply a seal coat of Resene Sureseal followed by two coats of Resene Lusta-Glo enamel.

Over time, light topcoat colours will yellow. There is no waterborne system for this application. In the early stages of using the fire there may be a solvent odour released as the paint becomes hotter but this will dissipate. It's best to allow ventilation during early use.

September 2019

Q. I need to specify paint for a footbridge walking surface.  Would you recommend a product. I am most concerned about coefficient of friction and durability - is it acceptable to paint only the top surface and what conditions does this need to be completed in?

The substrate is rough-sawn timber in an external environment on the West Coast, exposed to rain and approx. 500m from the coastline. The bridge is reasonably used with all kinds of footwear.

A. The only system we could offer would be to prime the decking with Resene Wood Primer and then apply two coats of Resene Non-Skid Deck & Path.

September 2019

Q. After two coats of Resene Lustacryl on interior French windows, when it is safe to blade back the glass? In other words how many days after the second coat? 

A. You'd be safe to do this after a few days, although if you can wait a week or two it allows the paint to cure. Ensure that you take care around areas you don't want to remove of course. Use a Stanley knife for nice straight lines.

September 2019

Q. I have white Resene Lumbersider spilled over my new concrete driveway, I tried to wash it off but it's still there and it's been about 3 months now.

A. You could use Resene Graffiti Cleaner to remove the paint. It will really depend on if it has penetrated into the concrete, as to whether you can remove it completely. You could also try waterblasting.

September 2019

Q. We have recently moved a glasshouse to our property and wondered what you recommend to paint the glass with, to protect the sun sensitive plants.

A. Often shade cloths etc. are a good and cost effective option to protect plants against UV as once the glass is painted you can't remove it.

However, to paint out glass we recommend (following a good clean down of the glass) applying an adhesion coat of Resene Waterborne Smooth Surface Sealer - allow to dry for 2-3 days as this will aid adhesion to the glass then topcoat with two coats of Resene Lumbersider.

Select a lighter colour, as dark colours could cause heat stress on the glass. White is best to deflect heat.

September 2019

Q. Can you tell me please what makes Resene AquaShield a good product to put on exterior stucco cement plaster and what does Resene product description mean when it says that it gives a 'Mediterranean look'?

A. Resene AquaShield is a flat mineral effect type coating which gives it that ‘Mediterranean' look i.e. that type of coating/look you commonly see on older buildings in Italy, France etc. It is a great match for the look of stucco houses.

It has a hydrophobic nature to it, so water will bead up and roll off the surface more than a standard paint coating. This means that you will get less dust and grime build up on the surface.

It also has the best level of Moisture Vapour Transfer in our range therefore is our most breathable coating.

September 2019

Q. We have an issue with efflorescence and slight water leakage on the internal concrete wall of our garage. There is no access to the external face of the wall as it is below ground level, Is/are there any Resene product/s that will seal the concrete from the inside/internal wall and prevent the issue we are facing. The house was built in the mid-1970s.

A. Thoroughly wire brush to remove any remaining efflorescence. Apply a saturation coat of Resene Solventborne Aquapel to bare concrete and leave to cure for at least 48 hours with ventilation, to allow for solvent removal from the room. Then apply two full coats of Resene HydraBlock.

September 2019

Q. My bedroom wardrobe was painted with foul smelling old paint that had gone off (I'll never know why). The smell is very strong and horrible and it's all through the house. Is there a product I can use to seal in the smell? I'm due to have new carpet laid in 4 days. 

A. If the paint was a waterborne paint, it may have been contaminated with bacteria. If this is the case then wipe the areas down using a bleach solution such as Resene Moss & Mould Killer diluted and used to label directions. Wipe down with water and a cloth after this treatment then allow to dry.  Then apply two coats of Resene Quick Dry primer undercoat. As long as the mould treatment is effective, Resene Quick Dry has a package to inhibit future mould growth. If you want a specific colour overcoat, paint the primed areas with two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom.

September 2019

Q. We live on a cliff right above the sea and we have had a new deck built. A steel frame consisting of two pillars and a large cross beam have been installed. This was manufactured in three sections, galvanised and epoxy painted. This was then erected using large bolts that my magnet sticks to very well suggesting that they are not stainless steel.

A couple of small scuffs and scratches were made during installation.

I need an external primer or sealer that will seal this steel to prevent any rust forming. I then need to paint them with a waterborne paint that I have used to paint all the timber pillars around the house.

A. Wash down the areas to be repaired using Resene Roof and Metal Wash diluted and used to label directions. Sand the existing epoxy coating to profile for recoating and feather off to a sound edge then spot off prime all bare prepared steel areas only, with Resene ArmourZinc 120 to achieve a dry film thickness of 75 microns. Ensure an overlap of 10mm onto sound existing painted surface. Then apply at least two coats of Resene Armourcote 221 epoxy primer over areas primed with Resene ArmourZinc 120.

Epoxy based cession systems are normally overcoated with a two pack polyurethane topcoat to give a weatherable topcoat. Resene exterior waterborne topcoats can be used but these do not achieve the same level of adhesion as a two pack polyurethane.

When applying topcoats to existing epoxy coating, ensure the existing coating is scrubbed down using Resene Roof and Metal Wash diluted and used to label directions to be chalk free then sand to profile for recoating.

September 2019

Q. I want to paint my 1950s weatherboard house. I'm pretty sure the weatherboards and windows are hardwood. I'm not sure exactly what wood. I'm planning on sanding the flaking areas of paint and spot priming before painting. Can you suggest the best way to prime/paint the hardwood?

A. Full preparation information is below for you. For paint products use:

  1. Spot prime with Resene Quick Dry
  2. Two topcoats of Resene Sonyx 101
  3. Spec Sheet 2:1/3 - Previously Painted Exterior Timber, Weatherboards and Plywood

Generally, painted exterior timber will be in reasonable condition with some moss and mould on the surface as well as salt, dirt and other contaminants and detritus. The degree of failure of the previously applied coatings will ultimately determine the amount of time and cost spent on preparing the surface (see also the notes above).

Where the paint surface has badly deteriorated, more extensive preparation, including possibly complete removal of the coating, may be required.

Step 1:  Treat moss and mould with Resene Moss & Mould Killer diluted and used to label directions.  For heavy infestations an additional application(s) may be needed.

Step 2:  Thoroughly scrub down using a solution of Resene Paint Prep and Housewash and water to remove all surface chalking, dirt, detritus, moss and mould residue, cobwebs and other contaminants. Use as directed on the label.  

Step 3:  Thoroughly scrape and sand to remove all loose and flaking paint to provide a good key for subsequent coats. Sand any grey weathered bare timber back to a sound timber surface. Ensure all areas of flaked paint are thoroughly sanded to a feathered edge. Ensure any sharp edges are arrised to a rounded profile.

Note II:  Remove or punch in any rusty nails and replace with galvanised or stainless steel nails as is appropriate. Any exposed nail heads unable to be replaced should be punched and spot primed with Resene GP Metal Primer, if practicable, and fill with Linseed oil putty. Any rust stains should be spot primed using Resene Wood Primer.

Step 4:  Spot prime all bare timber (including nail holes) with the specified timber primer. 

Step 5: All nail holes or areas of damaged timber having first been primed in Step 4, require filling with Resene EzyFill GP or similar, in accordance with manufacturer's instructions. Sand smooth and spot prime the filled areas, with specified timber primer.

Note III:  Treat rotten and cracked timber as per Spec Sheet 2:1A/3.

Note IV:  Where paint coatings need to be stripped refer to Spec Sheet 2:1B/3.

Note V:  Before beginning any surface preparation, tests should be done to ensure the old paint does not contain lead. Paint flakes with layers older than 1970 are likely to have lead in them. If lead based paints are identified on this job, then the OSH Guidelines for the Management of Lead-based Paint must be read and followed. Where these guidelines are in conflict with any part of this specification, the guidelines must take precedence. Flakes of lead paints and any sanding dust need to be carefully managed and disposed of.

Note VI: Older timber weatherboard clad homes, especially those located close to a coastal location are likely to have rusting nails which are susceptible to bending and breakage when weather boards undergo dimensional change such as can occur when there is a colour change to dark colours. We recommend replacement of nails with new galvanised or stainless nails to ensure dimensional changes are minimised.

Q. I have a new treated pine deck being built at present and am looking at your Resene Woodsman Decking Oil Stain. I want a durable product for an area that will be in the shade and wet for a lot of the year, and since I don't want any tracking inside and the most mould-resistant option thought this might be the best product? Is the CoolColour optional or is it a standard additive? What effect will it have on durability, look etc. of the product? Also, looking at the chart it seems it is not indicated for outdoor furniture and walls. We want to stain (and maybe later paint) a new pine adjoining shiplap wall and we also have a hardwood bench.  I'm concerned the product is not indicated for this use, and want to know why please? Also, with regard to mould resistance, is this your best product (decking or furniture)?

A. A Resene CoolColour™ system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. The CoolColour system will reduce but not eliminate heat related stress on the substrate.

There is no benefit in applying a CoolColour paint to areas that are not subject to full weathering/sun exposure.

Resene stains are designed to erode upon weathering, the erosion may release pigments that can be foot tracked inside but washing during rain usually sees the pigments being washed off the surface. This is the reason why we would not recommend its use for furniture as pigment transfer to clothing is a possibility.

The stains will not kill existing mould/algae but will inhibit growth; if the stain maintenance is not undertaken on a regular basis then mould growth can occur. Once this occurs, treatment with Resene Moss & Mould Killer is required to address future mould growth.

With some products we have a more clearly defined area of use – e.g. Resene Woodsman Decking Oil Stain. Resene Woodsman Wood Oil Stain has a wider use and hence there is no specific reference to use. We define our exterior stains as non-film forming, this allows for easy restaining as there will be no peeling/flaking as occurs with film forming stains.

Q. We have a new Pinex ceiling which is very porous. Can you suggest an undercoat or suitable sealer?

A. Resene Sureseal would be our recommendation.

September 2019

Q. We are using Resene Black on James Hardie Stria and quadruple strength Resene Surrender on Axon exterior. What paint do you recommend and can we use low sheen with CoolColour?

A. The Resene CoolColour™ Black system would be recommended; apply a full coat of Resene Quick Dry white and then finish with two coats of Resene Lumbersider CoolColour Black. A Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

October 2019

Q. We built our house in 2002 and used Resene products throughout, however we have dressed macrocarpa external fascia and barge boards which were coated with a different wood oil stain. I have recoated the fascia and barge boards with this product every 2 years since 2002 to retain the protection and look of these timber features. In the last 3-4 years the stain has started to bubble and peel on areas of the barge boards which are most exposed to the sun and the problem is becoming worse. While I realise it is necessary to sand back to the original timber, I am reluctant to reapply the stain because there will be a mismatch between the colour of the re-stained barge boards and the fascia, as the multiple coats of stain over the years have made the timber a rich dark brown colour.

Do you have a suitable stain or other product which can be colour matched to the fascia which do not require recoating?

Alternatively, I am considering sanding back and painting the affected areas and note that your Resene Brown Pod colour is a close match. Would you recommend this and if so, which products and application would you suggest? Do you have any other recommendations?

A. We regard all stains as high maintenance, in most exposure conditions, a Resene exterior wood stain on average will require recoating every third summer.

When recoating stains, there will be a build-up of colour over time to the extent that the stain colour is no longer semi-transparent and resembles a solid colour. This is the issue you have been seeing.

A complete strip of the existing stain coating and application of a solid colour system is the only way to achieve a long term system that does not require regular maintenance.

Strip the existing stain and sand areas of weathered timber to restore the original timber colour. Apply a full coat of Resene Wood Primer and follow with a full coat of Resene Quick Dry primer. Undercoat then finish with two coats of Resene Sonyx 101 tinted to the Resene CoolColour™ version of the topcoat colour.

October 2019

Q. I've got an old concrete outdoor seat that I need to rejuvenate. Is there a matt paint formulated for concrete furniture/statues? I don't want a shiny painted look but something that looks like it's been there for years.

A. Ensure the concrete is clean and free from bio growth, if the latter is present, treat with Resene Moss & Mould Killer diluted and used to label directions. Then apply a saturation coat of Resene Sureseal and finish with two coats of Resene Walk-on.

October 2019

Q. We are having a kauri bench top in our bathroom. What would be a good clear coating for this? The Kauri benchtop is new and currently being made.

A. Our only recommendation is four coats of Resene Polythane and at least 1 of the coats as a full envelope seal.

October 2019

Q. What product would you recommend to use over old concrete pavers? These are approx. 200x200 in size and we need to rejuvenate them by either sealing or using a stain type product in similar colourways. They are variable light terracotta.

A. Apply a saturation coat of Resene Solventborne Aquapel and leave to cure for at least 48 hours then apply two coats of Resene Concrete Stain.

October 2019

Q. In the bathroom, I am undercoating Resene Sureseal onto GIB® Aqualine. However there is some cement board around the bath. Can I use the Resene Quick Dry primer (used for the wood skirting), on the cement board, or do I need to use something else?

A. I recommend sealing the Aqualine and fibre cement board with Resene Sureseal then apply a full coat of Resene Quick Dry to all substrates then topcoat.

While the Resene Sureseal can be topcoated without the Resene Quick Dry, experience has shown that for wet areas such as bathrooms, with possible restricted ventilation/steam removal, that the Resene Quick Dry does give a belt and braces solution when a waterborne enamel topcoat is being used.

October 2019

Q. We recently took possession of a new house. We notice that in the two bathrooms the walls have developed wet shiny looking run marks, probably triggered from condensation (both rooms have extractor fans that we use). I have read about surfactants leaching out, but these marks are not chalky, just shiny like there is a drip of water running down the wall. It's dry to the touch and can be removed by wiping the walls with a damp cloth; however this is not something we have seen with other bathrooms. What do you think might be the issue?

A. The phenomenon you see, is more than likely surfactant leaching and commonly arises when a waterborne paint is applied under what the industry refers to as marginal curing conditions, usually low temperatures/high humidities and with poor ventilation to the painted area.

If the rooms are bathrooms, we do not recommend application of standard waterborne wall paint, as in a wet area these paints are more prone to surfactant leaching as the paint film does not cross link to give resistance to steam. Therefore there exists the possibility that the wrong paint type was used in the areas showing surfactant issues. For wet areas, Resene recommends conventional solventborne paints or Resene waterborne enamels.

October 2019

Q. We're thinking about repainting our bathroom. We originally painted it Resene Half Spanish white. Do bathroom walls require a special type of paint due to the moisture?

A. The topcoats used for wet areas/bathrooms are either solvent or waterborne enamels. Standard waterborne topcoats used for other areas can't be used in these areas as they are permeable to steam or a combination of condensation and increased atmospheric temperatures that exist in bathrooms.

October 2019

Q. I need to paint an old (+/- 30yr old) decramastic type (sheet metal with grit) tiled roof. The grit coating has worn off in many places and a lot of bare metal is showing through. What is the best primer to use before coating with Resene Lumbersider?

A. Remove any loose corrosion using 3M Rust and Paint Removal Disc and prime bare metal with two coats of Resene Galvo-Prime before topcoating.

October 2019

Q. My house is partially clad with cedar and the last owner told me he used tung oil on the timber but the timber has a darker finish.  Can you add stain after tung oil has been added to cedar?

A. The application of the tung oil (and there may have been multiple applications) will cross link seal the timber to an extent which can compromise stain adhesion/penetration. The darkness may be due to mould growth so as a first suggestion wash down the oiled areas using Resene Moss & Mould Killer diluted and used to label directions.

October 2019

Q. What is the best paint to use on a door threshold? The entrance doesn't get a lot of traffic (it's from the bedroom onto a deck) but it's on the second floor and faces north so it's exposed and gets a lot of sun. The timber is native; it's certainly not radiata.

A. Best to strip the existing coatings, sand smooth and then prime with two coats of Resene Quick Dry primer undercoat and finish with two coats of Resene Lustacryl.

If using a dark top coat colour we recommend using the Resene CoolColour™ version of the colour. A Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. The CoolColour system will reduce but not eliminate heat related stress on the substrate.

October 2019

Q. What is the recommended coating system (paints or sealants) for exterior H3.2 glulam beams?

A. We recommend Resene Wood Primer topcoated with two coats of Resene Sonyx 101.  Use the Resene CoolColour™ version of the topcoat colour if selecting a dark colour.

October 2019

Q. We have siding weatherboard and in their specification they ask for a continuous waterproof coating system.

A. Under the accepted NZ definition of waterproof no waterborne paints will achieve a waterproof surface. What will be achieved is a weatherproof system; the difference is that a weatherproof system allows water vapour to flux through the film but not liquid water.

October 2019

Q. I have just had the exterior of my home plastered and the colour of the plaster matched the joinery. I'm keen to find a clear undercoat/sealer that does not require painting so that the concrete look/colour can remain. Please can you let me know what product you recommend?

A. We recommend Resene XC-700 system, which is a clear finish.  It's not a DIY application and it will not have the same gloss level to the finish as bare concrete.

October 2019

Q. Would you recommend use of Resene X-300 or Resene X-400 versus Resene Sonyx 101 for better protection and seal of previously painted fibrolite asbestos cladding?

A. The sealing/consolidation of the fibrolite asbestos cladding (FC) substrata is from the sealer applied and not the topcoat system. Resene X-300E and Resene X-400 are high build topcoat systems which really do not add to the encapsulation of the asbestos fibres in the FC substrate.

Resene Sonyx 101 is a low build equivalent to the other two products but the same would apply to Resene Sonyx 101 as regards encapsulation.

The Resene sealer for bare FC containing asbestos is Resene Sureseal  which can be topcoated with any Resene waterborne topcoat system.

October 2019

Q. I have recently bought a cedar clad house and I'm not sure which product has been used on the cedar previously, water/oil/Wood-x based. I understand that I need to use the same product as has been used previously. How do I tell which product it has previously been treated with?

A. It is a huge challenge to definitively differentiate between different stain types.

We see that there are three main stain types, non-film forming, film forming and mineral oil stains (Resene exterior stains are non-film forming). Often film forming stains will peel or flake as their failure mode and this can be used to come to a conclusion on stain type or at least differentiate between a non-film and film forming stain.

Mineral oil stains are the tricky one; they do have excellent penetration into timber and while non film forming they cannot be overcoated with either of the alternative stain types. Despite our best technical efforts we have been unable to develop a method to verify the presence of a mineral oil stain.

Given all of these challenges we have to rely on a can of stain remaining on site in the garage or shed to enable stain identification beyond reasonable doubt.

October 2019

Q. How do you paint tyres? I want to use them in the garden for potatoes and other plants.

A. Wash down using Resene Paint Prep and Housewash diluted and used to label direction. Apply a prime coat of Resene Membrane Primer and finish with two coats of Resene Lumbersider (also can use Resene testpot paints).

October 2019

Q. Can you paint over old and worn clear coated cork tile flooring? What would you recommend?

A. Degrease thoroughly and to profile for recoating. Apply a full coat of Resene Quick Dry then apply two coats of Resene Walk-on and finish with a seal coat of  Resene Concrete Wax.

October 2019

Q. How long until I can paint my house that has been solid plastered, with stucco. I understand the lime in cement mix is an issue.

A. You can apply Resene LimeLock as soon as the plaster is touch dry.

October 2019

Q. What do I use to paint grey concrete pavers? I would like to modernise them with a rough look (sort of stucco). They are the 500 x 500 pavers that were probably put down when the house was built in 2006. At present, they are laying on dirt with stones around them. They are a walkway to our patio, so needs to be able to withstand constant foot traffic and hot sun all day.

A. Suggested system is to apply a saturation coat of Resene Solventborne Aquapel to the clean pavers and allow curing for at least 48 hours, then apply a saturation coat of Resene Sureseal  and finish with two coats of Resene Non-Skid Deck & Path.

October 2019

Q. Because I have dogs and will be using Resene Qristal ClearFloor on stairs I was wondering if Resene Qristal ClearFloor 2K would give a more durable finish?

A. In principle the two pack version will be more resistant to wear, but dog claws have an inane ability to scratch even the most hardwearing floor coatings. The Resene Qristal ClearFloor 1K version is easier to touch up, so if it was me I would go with the 1K version.

October 2019

Q. Our house is clad in Onduline. It's 10 years old, in good condition but a little faded. We would like to paint it. What product do you recommend please?

A. Treat areas of mould/algae growth with Resene Moss & Mould Killer diluted and used to label directions. Then scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Then apply full coat of Resene Galvo-Prime and finish with two coats of Resene Lumbersider. If selecting a dark topcoat colour, we recommend using the Resene CoolColour™ version of the topcoat colour.  Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

October 2019

Q. We are working on a new project with an in-situ exterior concrete wall and concrete block wall. Are there any products we can apply to the surface to give it a nice finish?

A. We usually focus on achieving a weathertight paint system for exterior concrete/blockwork. Resene X-200 is used for this application.

Note that application of the Resene X-200 system (3 coats) does not fill the block pointing, so if the blockwork is adjacent to a solid concrete wall there will be a visual difference.

October 2019

Q. I have a slatted wooden outdoor table which has been stained. It needs a revamp, and I was wondering what preparation is needed and what product would I use?

A. If all the existing stain can be sanded off to bare timber then I suggest Resene Timber and Furniture Gel.

October 2019

Q. Do you have a paint that is suitable to use on a wooden toy I've made?  It's for a toddler who still sticks things in his mouth so I want to make sure what I paint the toy with won't hurt him.  Obviously if we see him do it we will stop him but you know what kids are like.

A. We recommend Resene Lumbersider or Resene testpot colours.

October 2019

Q. Can Resene Lustacryl waterborne enamel be used over oil based enamel on skirting, architraves and doors, after a clean and light sanding without problems in future?

A. Yes, but to achieve the best possible adhesion you will need to ensure the existing enamel paint is clean and sanded to profile for recoating. To give the best adhesion of the Resene Lustacryl topcoat, apply a coat of Resene Quick Dry to the sanded surface.

With skirting/architraves it is essential to install a system to give maximum adhesion to reduce the chance of chipping.

October 2019

Q. Can a Resene Woodsman solventborne stain be applied over a 5 year old Resene Waterborne Woodsman stain?

A. Yes, treat areas of mould/algae using Resene Moss & Mould Killer diluted and used to label directions. Then apply Resene Timber and Deck Wash again diluted and used to label directions and scrub down using a stiff nylon scrubbing brush or broom, then rinse clean.

Allow to dry then apply the new Resene Woodsman Wood Oil Stain.

October 2019

Q. What is the best Resene product for painting a brick fireplace surround? The fireplace has an insert wood heater with a door. Elastomeric latex, heat resistant and oil or water based paint? The brick surround gets warm in parts but not hot. The bricks are glazed.

A. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before overcoating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen or Resene Lustacryl (semi-gloss).

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the glazed bricks.

October 2019

Q. We have Shadowclad on our house. Is it better to use Resene Wood Primer or Resene TimberLock first? We will use Resene Lumbersider as the topcoat.

The Shadowclad was not primed and some was fitted 10 years ago and some 12 months ago. It's in good condition, some needs the green washed off but otherwise it's good and solid and has never been coated with anything.

A. The green is more than likely algal growth and must be treated with Resene Moss & Mould Killer diluted and used to label directions to kill the bio growth, if this is not done a return of the bio growth will occur.

Suggest that you also apply the same treatment to the sections that are 12 months old. Scrub down using Resene Timber and Deck Wash diluted and used to label directions and allow the substrate to dry.

Then apply a coat of Resene TimberLock (wipe off excess at time of application) and leave to dry for at least 48 hours before applying a full coat of Resene Wood Primer then finish with two coats of Resene Lumbersider tinted to your selected topcoat colour. If selecting a dark colour we recommend applying the Resene CoolColour™ version of the colour. Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology. Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a Resene CoolColour is selected in place of a standard colour. The CoolColour system will reduce but not eliminate heat related stress on the substrate.

Shadowclad, painted or unpainted undergoes surface checking upon weathering, but this is said to only affect the outer layer of the pine laminate.

October 2019

Q. I am doing an art project and want people to do for me, three A4 paintings on card using your testpots. I want them to then post their paintings back to me. Obviously I want to avoid the cards and paint all sticking together. So my questions are: How long should they leave the paintings to dry before stacking them? And what should I provide as an interweave sheet between the A4 cards to give it extra protection? Butter paper or perhaps tracing paper? I think some of your colour charts have a non-stick paper in them so hopefully you understand what I mean.

A. Resene testpot paints are made using a conventional waterborne resin system, the cured paint will never have what is referred to as block resistance (two painted surfaces will stick if in contact and under pressure).

When we send out Resene drawdown samples made using the same paint, we place a sheet of strong tissue paper between the drawdown sheets to avid the sticking together issue. Thin cardboard will be just as effective.

October 2019

Q. We are cladding our house with woodgrain effect fibre cement (BGC Stratum Woodgrain product) which we would like to stain in Heartwood or Light Oak colour to imitate timber. I understand that the best products are Resene Sureseal first, then using Resene Sonyx 101 and finally Resene Forester. I was not able to find Sonyx in either Heartwood or Light Oak colour. Would you please advise whether I am missing something?  Also will using this system cover off any surface imperfections of the fibre cement (i.e. marks, fillers, white prime coat marks, pencil marks etc.)?

A. There is a specific Resene Sonyx 101 base colour to be used in conjunction with the Resene Forester glaze coats to achieve the required topcoat colour effect.

If you apply the full Resene Forester system including the tinted basecoat colour, this should cover most of the defects you describe, however bare fibre cement and filled areas will need to be primed with Resene Concrete Primer before applying the Resene Forester basecoat colour.

October 2019

Q. I wish to paint the exterior of a two storey house, clad with Shadowclad grooved ply and originally coated with what I believe to be water based exterior wood stain. Can you please give advice on the different coat types and number of coats I will need? If it needs to be sealed, is that available in conjunction with an undercoat? I am thinking white for the top storey at this stage.

The stain is old and the timber definitely needs repainting. I would guess it was the original coating which would have been done mid to late 2002. There are no signs of mound or algae, just various sections exposed to the elements fading more than other sections. Apart from that, the cladding is in good condition and weatherproof.

A. Scrub down using Resene Paint Prep and Housewash diluted and used to label directions.

Apply a full coat of Resene Wood Primer and finish with two coats of Resene Lumbersider. If selecting a dark colour, we recommend application of the Resene CoolColour™ version of the topcoat colour. A Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. The CoolColour system will reduce but not eliminate heat related stress on the substrate.

October 2019
Q. I have rusty steel gate hinges on a plywood door, which is painted with Resene Lumbersider. I have scraped back the rust and applied some Resene Rust-Arrest primer. Can I now paint the hinge with Resene Lumbersider to blend in with the door or does there need to be something between the Resene Rust-Arrest and Resene Lumbersider?

A. For best results when painting rusted steel, the steel should be washed down using Resene Roof and Metal Wash diluted and used to label directions and loose corrosion products removed by wire brushing before priming.

Suggest you topcoat the cured Resene Rust-Arrest with a coat of Resene Galvo-Prime before applying the waterborne topcoats.

From experience, you can get rust staining from the metal that is in direct contact with the timber. There is no paint solution to control this scenario.

October 2019

Q. Can I paint Resene Lumbersider over the top of Resene Sonyx 101 paint?

A. Yes, as long as the base paint is sound and chalk free. Suggest you wash down using Resene Paint Prep and Housewash diluted and used to label directions first.

October 2019

Q. We have a timber floor garage on piles and two layers of structural plywood above it. Do you have any paint that is suitable for the garage floor and can keep joists away from water?

A. The only system we could offer would be to prime the plywood with two coats of Resene Quick Dry and allow the primer to dry for at least 48 hours after the last coat is applied. Then apply two coats of Resene Uracryl 402, leave to cure with ventilation for five days before driving onto the painted ply.

Not sure exactly what you mean by keep water away from joists but the paint system will stop liquid water ingress into the ply sheeting.

October 2019

Q. I am looking at painting my boat trailer with Resene Alumastic. Would it be okay to use water based rust converter first? That is unless you have a better product to paint the trailer with. 

A. If any areas of moss or mould infestation exist, then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations more applications may be needed.

Scrub down using  Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water, ensuring all salts are also removed.     

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure waterblasting, taking care not to damage either the substrate or the surrounding areas. 

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place, the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish. 

Note: The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

We do not recommend using rust converters, but you should prime areas of prepared corrosion using a coat of Resene Armourcote 221 before applying the Resene Alumastic. Resene Alumastic is a barrier coating and must be applied to achieve the dry film thickness on the data sheet. I would suggest that you apply a full coat of Resene Armourcote 221 as a priming system.

October 2019

Q. What is the Shadowclad painting process when new but has weathered over three months of winter? How do I clean it and what primer do I use? Is a low sheen required?

A. Treat any areas of mould/algae with Resene Moss & Mould Killer diluted and used to label directions follow this with a clean down with Resene Timber and Deck Wash again diluted and used to label directions. Allow to dry out and apply a full coat of Resene Wood Primer and finish with two coats of Resene Lumbersider tinted colour.

If choosing dark colours we recommend the Resene CoolColour™ version of the colour. A Resene CoolColour system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. The CoolColour system will reduce but not eliminate heat related stress on the substrate.

October 2019

Q. Could you please give advice for a clear concrete paint for facade and roof, to apply on concrete cement sheets - James Hardie Hardiflex™?

A. Apply a saturation coat of Resene Solventborne Aquapel and leave to cure for at least 48 hours then apply a coat of Resene Concrete Clear Gloss thinned 10% with water and finish with two coats of Resene Concrete Clear of any of the available gloss levels.

October 2019

Q. Our painter has put Resene Sonyx 101 semi-gloss black on our house and did three coats within 8 hours on Friday and it looks terrible. I see Resene Lumbersider low sheen is recommended by James Hardie, so obviously he's used the wrong paint and can you advise the minimum time between coats with this Resene Sonyx 101 paint?

You can see brush marks, in areas it looks thick and there are runs and it looks like cross over roller marks. What do we need to do before we put the low sheen on i.e. sand back to undercoat or just give semi-gloss light sand etc?

A. There is no technical reason why Resene Sonyx 101 could not be used as the topcoat, James Hardie recommend a low gloss topcoat as this assists with hiding substrate variations.

To get three coats on in one day is not what we would recommend for brush/roller application.

There should be no runs or sags in the applied film, as this can only occur of excessive paint thickness was applied per coat or the paint was over thinned.

Sanding of a waterborne paint such as Resene Sonyx 101 is not an easy undertaking as the heat created by sanding causes the paint to ball up rather than dust off. This is even worse when the paint is fresh. This is a feature common to all waterborne paints based on a conventional waterborne paint resin.

Wet sanding using wet and dry paper is the only way to attempt sanding to remove surface defects, the coarsest grade of wet and dry paper we sell is 150 grit and I suggest that this is the grade you start off with to remove gross imperfections then more to a finer grade to finish.

You may well have to reprime, if possible avoid sanding through the entire paint system to the base substrate.  Then recoat in two white coats to get complete coverage in white, then the Resene Lumbersider Black.

There will always be the potential for brush marking to occur when applying waterborne paint, even more so if a dark colour is applied in direct sun as the paint dries quickly and does not have sufficient time to flow and level. Resene does have Resene Hot Weather Additive to extend the open time of our waterborne paints, to allow for more time to get flow and levelling. Brush marking is always more visually obvious with darker colours.

October 2019

Q. I would like to apply stain to repair concrete – what do you recommend? 

A. Application of a stain to concrete that has repairs is a challenge to achieve a finish that does not highlight the concrete repairs, due to the fact that stains are semi-transparent. If the repair material is an exact match to the concrete colour then the differences are reduced.

October 2019

Q. How should I prep an oiled timber door ready to be painted?  The door was last oiled 10 plus years ago.  Can I use an acrylic paint or should I use an oil based paint to finish?  It is a sheltered exterior door, probably rimu. It last had any attention over 10 years ago. No weather damage or mould. It's in good condition we would just like to change the colour and paint it.

A. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, paying particular attention to hand contact areas. Then sand using 220 grit sandpaper to profile for recoating. Apply a coat of Resene Wood Primer and finish with two coats of Resene Lustacryl. The oil will need to be hard dry, if not then sanding will be difficult.

October 2019

Q. When using Resene X-200 paint system on previously painted 20 year old plaster house (in very sound condition) do I need to use a primer or is two topcoats of Resene X-200 enough?

A. Treat any areas of moss/mould/algae with Resene Moss & Mould Killer diluted and used to label directions then scrub down using Resene Paint Prep and Housewash diluted and used to label directions to achieve a sound chalk free surface. Then you can apply the Resene X-200 system without the need for priming.

October 2019

Q. We used the Resene Write-on Wall Paint on our daughter’s wall a couple of years ago and now wish to paint over it with standard Resene paint. Can you tell me the best way to either remove the Resene Write-on Wall Paint or the best method to paint over it? 

A. Wipe the coated area down with meths and a cloth to remove any residual marker residues then sand with 220 grit sandpaper to de-gloss (no need to fully sand off the Resene Write-On Wall Paint layer, just to profile for recoating.

Apply a full coat of Resene Quick Dry and finish with two coats of Resene Zylone Sheen or Resene SpaceCote Low Sheen.

October 2019

Q. I am painting the exterior of a small unit that has Summerhill stone cladding and looking for advice on how best to do so please.  The existing paint has been on there for well over 10 years, do I need to waterblast it off? Following that do I need to prime it or just paint two coats on top?  What is the recommended paint product for exterior Summerhill stone? Some people say elastomeric, Resene Lumbersider or premium acrylic.

A. Treat areas of mould/algae growth with Resene Moss & Mould Killer diluted and used to label directions then scrub down using Resene Paint Prep and Housewash again to label directions. Then assuming the existing paint system is sound apply any waterborne Resene exterior paint system.

If you are considering changing the topcoat colour to a dark colour, as the heat associated with a dark colour may well see failure of the existing paint system. A Resene CoolColour™ system will not render the painted surface cool to touch, but the Resene CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

October 2019

Q. I have a metal balustrade that has peeling paint and a little rust (not been painted in over a decade). It's not in a high corrosion environment, but the bottom of the balustrade can sometimes be submerged slightly when it rains and water ponds on the deck. Considering I don't know what type of metal the balustrade is, what is the best paint system to use? Yes, I can unscrew a section of the balustrade and remove the current paint and rust.

A. If any areas of moss or mould infestation exist then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations more applications may be needed.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure water-blasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note: The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

Apply Resene ArmourZinc 110 to achieve a dry film thickness of 75 microns followed by a full coat of Resene Galvo One and then finish with two coats of Resene Lustacryl topcoat.

Q. I'm a muralist using mostly Resene products I have a client wanting some paintwork on powder-coated aluminium downpipes.  Do I have any acrylic options or options apart from more of the same?

A. The issue here is to the topcoat but getting adhesion to the powder coated surface. For small areas carefully wet sand the powder coating using 400 wet and dry paper, wipe clean then apply a coat of Resene Galvo-Prime before applying two coats of a Resene external waterborne topcoat. You can use Resene Lumbersider or Resene Sonyx 101.

You can apply a coat of Resene Clearcoat UVS to achieve an increase in durability to U.V.

Q. Is there a paint suitable to cover splashback ceramic tiles in the kitchen? I'm looking for a cost effective way to change the colour of the tiles that is going to be durable and easily cleaned of kitchen residue.  If there is a product what would the preparation process be?

A. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before overcoating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the tile surface. The paint system will not give the same heat resistance as the tiled surface.

November 2019

Q. I am painting the interior of an old caravan which has a vinyl covering on the cupboards. Do I need to seal it and if so which sealer and then does it also need an undercoat before the topcoat?

A. Apply Resene Vinyl Wallpaper Sealer then two coats of Resene SpaceCote wall paint.

The sealer will dry very quickly, make sure that when you are applying the sealer that you establish good ventilation. Do not try to recover the roller sleeve or brush used to apply the sealer as the cleaning requires large volumes of solvent.

November 2019

Q. I am looking for a coating for the tanalised cedar shingle on my roof that will prevent the CCA treatment leaching into the tanks we rely on for our water supply. Any coating would have to be totally non-toxic, stable and not dissolve when exposed to rain and U.V for long periods.

Some shingles have been in place and weathering for a year, others will be entirely new.  I have been unable to source untanalised shingles and for various reasons alternative roofing materials are not practical.

A. A possible system is to apply a prime coat of Resene Wood Primer and then to apply 2 coats of Resene Summit Roof.

Disconnect roof downpipes until after the first shower of rain in order to flush away surplus non-toxic wetting agents before the surface is used for thecollection of drinking water. The paint system will only be effective on areas accessible to paint.

November 2019

Q. What paint do you recommend to paint beehives?  I'm about to buy some hives and boxes.

A. Resene Lumbersider is used for painting the exterior of bee hives. The product is Resene Environmental Choice Approved and contains no heavy metals or formaldehyde.

November 2019

Q. i have a mouldy ceiling I need to paint. Can i use the Resene Sureseal to cover it as the undercoat?

A. You will need to treat the mould areas using Resene Moss & Mould Killer diluted and used to label directions. Then apply a seal coat of Resene Sureseal followed by a coat of Resene Quick Dry before applying two coats of topcoat paint.

November 2019

Q. My kitchen/dining and bathroom have varnished cork tile over wooden floorboards. My options are to rip up the cork and redo the floorboards, or to paint over the cork. If I was to paint the cork, what do I need to do for prep and which products would I need to use? These are obviously high traffic areas with potential water spills. Is an overcoat needed also?

A. Ensure the existing clear is free of oil/grease then sand to profile (180 or 220 grit paper). Dust off then apply a coat of Resene Quick Dry waterborne primer undercoat followed by two coats of Resene Lustacryl. Leave the Resene Lustacryl to cure for at least 48 hours after application of the second coat then apply a seal coat of Resene Concrete Wax.

November 2019

Q. Is Resene Enamacryl suitable to repaint a garage roller door, or would you advise another type?

A. If the roller door rolls up to have painted surfaces touch then you will have to use a cross linked paint such as Resene Enamacryl.

The alternative for a flat garage door is to use a standard waterborne paint such as Resene Hi-Glo or Resene Sonyx 101, however if two painted surfaces are in contact the paint surfaces will fuse to form a single layer of paint.

November 2019

Q. I have a particle board floor in a mid-80s Lockwood house. I want to paint it a light colour to offset the pattern/colour of the wooden walls and cathedral ceilings. The floors are now carpeted but have been sealed sometime in the past. What would you recommend re sealing, paint application and polyurethane protection?

A. The polyurethane will need to be sanded to achieve a uniform smooth finish then apply a coat of Resene Quick Dry then apply two coats of Resene Lustacryl. If you want to increase the wear protection apply a coat of Resene Concrete Wax over the Resene Lustacryl.  Allow the Resene Lustacryl. to cure for at least 48 hours before clear coating.

November 2019

Q. Our painter quoted to spray our roof with two coats of Resene paint, however he has come back to us and said he wants to do one heavy coat instead.  He will be brush painting the edges butting up against the Gutter guard.  Is spraying two coats better than one heavy coat or vice versa?

A. Most roof coating undertaken by commercial trade painters is by spray application and a single spray application to achieve the wet film thickness of two coats is now becoming the norm.

November 2019

Q. It is time to paint external thin pine cladding that previously had linseed oil applied five years ago so it is well dried out and needing paint. I want to do a dark brown stain and am wondering which stains would be suited?  Also what pre-application preparation I might need to do?

A. Treat with Resene Moss & Mould Killer diluted and used to label directions then scrub down with Resene Timber and Deck Wash diluted and used to label directions.  Then apply two coats of Resene Waterborne Woodsman wood stain.

November 2019

Q. What is the best Resene paint to both protect and improve the look of a butynol covered, weather exposed deck?

A. Scrub the deck down using Resene Paint Prep and Housewash diluted and used to label directions. Then apply an adhesion coat of Resene Membrane Primer and finish with two coats of Resene Walk-on.

A Resene CoolColour™ system will not render the painted surface cool to touch, but the CoolColour system will reflect more heat than the same colour made on non-cool pigment technology.

November 2019

Q. I live in a 1970s 'townhouse' just around the corner from the beach. My son is going to be painting the exterior of my house.  This is the first time I haven't used a commercial painter and so I need to buy my own paint.

The walls of the house (Hardiplank on the bottom half and fibre cement sheeting on the top half and side walls) were previously painted in Resene Sonyx 101 waterborne semi-gloss, and the wooden window surrounds in Resene Lustacryl semi-gloss waterborne enamel.   As far as I can tell, Resene Quick Dry primer undercoat was used throughout.

The paint on the walls has lasted really well, whereas the enamel on the wooden window surrounds is cracked and peeling.

Should I go ahead and buy exactly the same paint this time?  Is there any advantage in painting the walls of the house in waterborne enamel (can I paint enamel over acrylic?) or the wooden window surrounds in oil-based enamel (I'm pretty old school!!!)?

Can I use up the old paint first (it's 8 years old), or should I dump it?

A. Resene Sonyx 101 is perfectly suitable as the topcoat for the cladding (walls). There is no need or benefit in changing this to a waterborne enamel paint.

I would suggest that the windows are stripped back to bare, prime the bare timber with Resene Quick Dry then apply two coats of Resene Lustacryl or Resene Enamacryl waterborne enamel. Resene Enamacryl gloss is not a high gloss finish but it will have a longer time to the onset of chalking compared to a solvent borne enamel such as Resene Super Gloss. Resene Lustacryl allows for a semi-gloss exterior topcoat.

Re the old paint, open the can and stir well to see if the paint can be re constituted to a homogenous mix, then carefully smell the paint odour.  If it smells 'off' (only way to describe this is socks that have been repeatedly worn without washing) then the paint has bacterial contamination and should not be used.

Your son will need to wash down using Resene Paint Prep and Housewash diluted and used to label directions before painting to achieve a clean chalk free surface.

November 2019

Q. We are going to put 7mm plywood as a flooring in our caravan. Which product (stain, varnish…) is best to use that can handle high traffic and is easy to wipe? Do we have to seal it before applying any paint/stain?

A. For single pack products our hardest wearing clear is Resene Polythane. If you did not want to use a solventborne system then the next best is Resene Aquaclear waterborne urethane. The higher the gloss level the better the wear. You can apply a Resene Colorwood stain colour prior to clear coating.

November 2019

Q. Will the Resene pool paint behave well going over an old two part epoxy?

A. Sorry, but a definite no to applying the Resene pool paint over an old epoxy pool paint.

November 2019

Q. I need to know the process of how to paint a concrete pool using your pool paint. Previously painted but now almost back to concrete. The pool was built in the 1980s and I don't think it has been touched since. Do I need a sealer? If so what? What Resene cleaners and paints should I use?

A. Resene Swimming Pool Paint can only be applied over the same paint in sound condition. Soda blasting is a good way to remove pool paint without the issues associated with sand blasting.

Salt water chlorination systems are particularly aggressive to the coating and a quick onset of surface chalking may result with this water treatment system compared to traditional hypochlorite tablets.

November 2019

Q. I have a 1980s house and the windows are aluminium powdercoated brown, do you know what the colour brown they used as standard for the windows?

A. Windows in Bronze or Lignite were the most popular.

November 2019

Q. I have just made three, small, two concrete block high spaces to fill with soil so I can grow vegetables in an area that is wet in winter but dry in summer. To counter the soil drying out quickly in summer, I thought I would paint the inside of the concrete blocks before the soil goes in. It wouldn't have to do the job perfectly, but I hate the thought of toxins leeching out of the paint and being taken up by the vegetables.

Could I use Resene Water Lockout or Resene Sonyx 101 or one of the products recommended for food producing factories or is it safest to just leave the naked concrete blocks? I see "Water Lockout" has, as one of its recommended uses...painting the lining of wooden planters...but is that intended for flower growing and not edible plants?

A. We recommend multiple coats of Resene Water Lockout until a smooth finish is achieved.

November 2019

Q. I am going to repaint two permanently sited caravans which have a mixture of mostly aluminium and some fibreglass. There is a small amount of exposed aluminium where the paint has faded. What do you suggest in terms of prep and topcoats?  I really want to keep it simple. it's not a flash project and there are only a couple of spots that are exposed metal.

A. The simplest system would be to prime bare aluminium with Resene Vinyl Etch, followed by a coat of Resene Galvo-Prime and then finish with two coats of Resene Lustacryl.

November 2019

Q. I have a 1960s rimu weatherboard house. I will be taking it back to bare wood by removing all previous layers of paint and undercoat and would like to know the best undercoat to use. I will be applying a light to mid grey colour. What would be the best paint type for this situation?

A. Suggest Resene Wood Primer is the most appropriate primer to apply to the stripped rimu. Are you sure that the timber is rimu?

It may be matai and if it is the Resene Wood Primer will not dry when applied to bare matai. Resene Quick Dry is the primer for matai. Resene Quick Dry can be used to prime rimu but my preference is to use Resene Wood Primer.

You may need to purchase a 500ml can of Resene Wood Primer and test drying over a bare section of the timber.

November 2019

Q. I want to paint some Lundia bookshelves which have previously been coated in clear solvent-based polyurethane. Can you please suggest the paint system and would you suggest using a solvent based paint on the shelves or will a waterbased paint such as Resene Lustacryl be OK?

A. Sand to profile using 220 grit sandpaper, taking care not to causes deep scratches,dust off and apply a full coat of Resene Quick Dry and finish with two coats of Resene Lustacryl.

November 2019

Q. Can you please advise what paint system you would use to paint an old concrete garage and laundry floor?   The floor while old is free from oil.   I would like a glossy, light colour like grey.

A. Resene Aquapoxy for Flooring would be our recommendation.

Check using the water splash test for the presence of a curing membrane, water splashed onto the concrete should immediately darken the concrete and be absorbed. If the water test indicates the presence of a curing membrane diamond grind to remove the existing curing membrane and to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

November 2019

Q. I am to build a privacy screen out of pine decking and want to know how and when to stain it and with what? I have been told it needs to be a recessive colour.

A. For vertical timber you can use Resene Waterborne Woodsman. A recessive colour usually means dark.

November 2019

Q. Can waterbased acrylic paint be used on a skyline cottage (COLORSTEEL®)?

A. Yes, but a coat of Resene Pre-Coated Steel Primer must be applied first.

November 2019

Q. I was on site today, and I observed some light white rust on an existing balustrade, which is part of a remediation project we are working on. Please can you indicate whether this requires further treatment, and if this is the case, please can you provide us rust treatment methodology?

The balustrade has had a new additional rail welded to the existing, the weld has been cold galvanised and the handrails have been primed with a zinc rich primer (white coloured on the top two rails).

The lower section is existing and is hot dipped galv and has been painted.

A. While the presence of white rust may be age related it is highly likely that there is under film corrosion present. Given this the existing paint system should be stripped, prior to stripping wash down using Resene Paint Prep and Housewash diluted and used to label directions to remove surface contaminants including salt. After stripping remove all areas of white corrosion material and as much red rust as is practicable using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas. Then apply the following paint system - Resene Armourzinc 120 (75 microns DFT), Resene Armourcote 221 (100 microns DFT) and finish with two coats of Resene Uracryl 403 (100 microns DFT). If the balustrades are not subject to regular rain washing increase the Resene Armourcote (DFT to 150 microns). For new hot dipped galv the same system applies but without the Resene Armourzinc 120.

November 2019

Q. I am in the process of finishing a mosaic picture that's mostly glass with a painted background. I'm looking for a sealant to protect the picture. There's a lot of little pieces of glass, some on top of each other as the main object is a tree.  I need to stop dirt and dust getting in as will be difficult to clean. It will then go on the wall.

A. We don't have a dedicated clear system, for this application, but I recommend a coat of Resene Imperite I.F 502 clear be applied as the adhesion coat, leave to cure for at least 48 hours then apply two coats of a Resene Uracryl 400 Series UVS Clear.

November 2019

Q. We are about to move into a 1978 house with very old carpet laid on a concrete slab. We are going to remove the carpet on day 1, but it may be some months before we finish renovations and get new carpet down. We were therefore considering painting the concrete slab to keep any dust down. Is that necessary? Could we use ordinary paint given that it is only an interior temporary solution? Would anything we put down have an adverse reaction with the new underlay and carpet?

A. My experience is that it shouldn't really be necessary however if there is a dust problem when the carpet comes up you could simply apply Resene Cemseal as a dust coat. This is easily applied by garden sprayer.

Keep in mind you should clean the surface of all dust and contamination before applying Resene Cemseal.

November 2019

Q. I have rimu bedroom furniture and wish to modernise it with whitewash.  What is the process?

A. If your furniture has a polyurethane finish on it, you could use Resene Colorwood Whitewash to change the appearance. You can get a Resene testpot from one of our Resene ColorShops to test it out first before undertaken the whole project. (Trial an area out of the way first to make sure it's the look you're after).

November 2019

Q. I am planning on painting my powder coated, wardrobe door frames. Do I need to have the powder coating removed first or what primer do I need to use?

A. The following can be used to paint interior powder coating:

Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, paying particular attention to hand contact areas. Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before overcoating. Then apply two coats of Resene SpaceCote Low Sheen or Resene Lustacryl semi-gloss.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

November 2019

Q. After cleaning down a veneer brick wall what product would you use to restore it to look like the original?

A. Resene Concrete Clear would be our only option for this. I'd recommend trialling an area first if possible to ensure you achieve the look you are after.

One thing to keep in mind is when you apply a clear coating over brick or concrete they can be affected by any moisture that is in or exiting the substrate. If moisture is present it will cause the clear coating to go cloudy/milky in that area. Any efflorescence occurring (white powder deposits where moisture is present) in the substrate will also create problems as it will continue.

November 2019

Q. I have just laid a new concrete pad for a dog run and kennel to go on top of. The concrete has to be sealed with a product to protect from water/urine penetration. The area will be hosed off daily. What product would you recommend and would it be safe for animals please?

A. If you want an easily applied product that doesn't change the natural look of the concrete an option would be to apply two saturation coats of Resene Aquapel (solventborne). It will penetrate and disappear but impart water repellency to the concrete. It will require recoating but this is an easy process as it's applied by way of garden sprayer.

If you were requiring a durable paint coating system we can provide this also however it will require full prep of the concrete (diamond grinding) and a 3-4 coat epoxy/urethane type system. We do have these types of systems in dog kennels at the Blind Foundation etc.

November 2019

Q. We wanted to do a quick paint over of our caravan as we have to leave it at a pal's place for a couple of weeks. Unfortunately we used interior paint. Any suggestions for a quick fix here?

A. Easy fix here as you could just apply a couple of coats of exterior acrylic paint over the Interior acrylic you've used (acrylic sticks to acrylic - interior or exterior). I'd recommend two coats of Resene Sonyx 101.

November 2019

Q. I need to purchase pale grey concrete paint for my steps and patio.  Is this something that Resene can help me with?

A. Yes, we recommend Resene Walk-on.

November 2019

Q. I want to have a pink fridge - but the only ones available are too expensive. Is there a way I can paint my current fridge and what do you suggest? I'm thinking Resene Waterborne Smooth Surface Sealer first (don't want to sand if possible) then what do I use - a gloss enamel? I really don't want to spray it. 

A. Yes you could use the Resene Waterborne Smooth Surface Sealer as the adhesion primer.

Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better.

The data sheet gives a shorter recoat time but the longer the sealer is left to cure the better. Apply a coat of Resene Enamel Undercoat before topcoating with Resene Super Gloss tinted to your desired colour.

November 2019

Q. I am going to do a project on picnic tables and am wondering what type of paint to use, i don't want to use a stain though. I also want to paint small designs on them, what type paint would be suitable for that too. Also what type of primer and finish do you recommend for these picnic tables?

A. If the timber has weathered sand to restore the original timber colour, dust off and apply a coat of Resene Quick Dry waterborne primer undercoat and finish with two coats of Resene Lumbersider colour. 

For the design you can also use a Resene testpot colour if only small areas are to be painted. For increased UV protection you can apply a coat of Resene Clearcoat UVS to the base Resene Lumbersider testpot paint.

November 2019

Q. I want to clear seal a sand/cement plastered concrete block wall. Should I use one coat Resene Solventborne Aquapel and two coats Resene XC-700?

A. The Resene XC-700 system was developed for concrete masonry walls.

This is not to say that it cannot be used for solid plaster, based on the analogy with Resene XC-700, two coats of Resene XC-700 applied over the plaster system to which Resene Solventborne Aquapel has been applied should be sufficient coating.

However I would apply a final coat (three coats of Resene XC-700) to be safe. Apply a saturation coat of Resene Solventborne Aquapel and leave to cure for at least 48 hours before overcoating.

November 2019

Q. We need to coat macrocarpa slabs to use as table tops in a bar.  The tables will be inside but subjected to sunlight coming through a large open door for about five hours each day.  We are after a finish that is scratch resistant and will not yellow from UV.  The slabs have already been sealed with a two part epoxy sealer that anything can be put over - resins, varnishes and even oils.  The sealer was applied by someone else and they are not willing to disclose the name of the product. Can you please recommend the best product to use as a coating?  I would prefer a low sheen finish.

A. Epoxies will yellow if exposed to light so there may already be a degree  of yellowing occurring.

Best recommendation is to sand the epoxy coating and apply two coats of Resene Uracryl 403 UVS Clear. The UVS version of the clear will give UV protection but will not correct existing UV induced yellowing.

November 2019

Q. How do I avoid getting an orange peel effect when using a roller to undercoat and gloss interior doors?

A. Roller texture, orange peel is always seen with roller application. The only way to reduce this is to brush lay off using a dry paint brush while the roiled coating is still wet. Roller sleeve selection can also influence roller texture.

November 2019

Q. Can I have a Resene Concrete Wax specification for a new concrete floor, please?

A. Check using the water splash test for the presence of a curing membrane. Water splashed onto the concrete should immediately darken the concrete and be absorbed. If the water is not immediately absorbed and the wet concrete does not darkens then this indicates the presence of a curing membrane.

If the splash test indicates the presence of a curing membrane then diamond grind to remove the existing curing membrane and to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

Then apply multiple coats of Resene Concrete Wax, following the data sheet information.

November 2019

Q. My home is a 1935 original which was extended, refurbished and modernised in 2016. The exterior is breaking down to varying degrees in multiple places and areas both on the old 1935 cedar and the new pine weatherboard section on the sunnier sides of the home.

A. The breakdown on the new pine is resin exudation from the timber, a common issue. The darker the colour the greater the potential for this to occur. Difficult to get 100% control of as I have seen resin exudation occur even with a white topcoat. 

Using a tungsten blade scraper scrape the areas showing exudation to remove the paint and surface resin deposits. Sand back to achieve a sound feathered edge, note that the resin may clog the paper which will require new paper be used. Prime the prepared areas with Resene Aluminium Wood Primer, then apply two coats of topcoat colour.

Areas showing breakdown on the old cedar need to be similarly prepared but change the primer for bare cedar to Resene Wood Primer.

November 2019

Q. I am looking at painting the interior of our concrete block garage white or off white as we are getting garage carpet installed. What do you recommend for paint and can you point me in the direction of where to look for colours and inspiration? Also do you recommend using roller or brushes?

A. The exterior wall faces will need to be made weathertight before painting the interior walls, Resene X-200 applied in three coats will achieve this.

Rolling is certainly the most efficient way to apply paint. For the interior the system would be a coat of Resene Concrete Primer and two coats of Resene SpaceCote Low Sheen.

November 2019

Q. I'm looking to paint my concrete roof tiles this summer.  The tiles are about 28 years old and are quite sandy (worn). Do you suggest anything for sealing, undercoating and topcoat for a terracotta coloured roof?

A. Weathered concrete/terracotta tile roofs are typically infested with mould, widespread lichen and moss growth. Removal of these are critical to achieving a successful long term decorative paint system.

Step 1: Rake out all joints and tile over laps to remove accumulated debris. Remove large clumps of moss using a scraper.

Step 2: Spot treat areas of heavy lichen infestation with Resene Moss & Mould Killer diluted 1:1 with water and leave for 48 hours before proceeding to Step 3.

Step 3: Treat areas of moss / lichen infestation a few weeks prior to the commencement of painting with a saturation coat of Resene Deep Clean diluted and used to label instructions. Resene Deep Clean is a slow release bio kill agent. Resene Deep Clean is best applied under overcast conditions to maximise wetting time.

Step 4: Water blast at the maximum pressure that will not damage tiles to remove all dirt, grease, moss and mould residue, dust, and other contaminants. Care is needed not to water-blast under the tiles. Allow the surface to dry thoroughly. Resene recommend that downpipes are disconnected during this process and that gutters are thoroughly cleaned out before reconnecting downpipes. Leave down pipes disconnected for the first few showers of rain to wash out surfactants from the top paint film.

The paint system is a full coat of Resene Sureseal and then two coats of Resene Summit Roof.

November 2019

Q. Among your numerous products are there any recommended products for painting intertenancy block walls?

A. The Resene X-200 system is our long standing system for exterior block walls – use three coats to achieve a weathertight system.

November 2019

Q. I want to use Resene Polythane to paint my hardwood kitchen countertops. Can you please advise if Resene Polythane is safe to use on countertops where food will be prepared?

A. No issues once the Resene Polythane system is fully cured.

November 2019

Q. On a new exterior timber (H3.2 or H4 cca treated timber) balustrade: Will a timber stain or a paint require less frequent maintenance? Specifically how often is painting or staining recommended?  Which is the cheaper option paint or stain?

A. Application of a solid paint system will achieve the longest maintenance interval typically 8 years +, staining is high maintenance with maintenance required on average every third summer. Depending upon the exposure conditions this may well be shorter particularly on a northerly elevation.

While the upfront cost of a solid colour system would be higher than a stain system the shorter maintenance time for stains may not give a long term cost saving.

November 2019

Q. We want to paint our aluminium double front doors from a white/cream to Resene Fuscous Grey. We also need to fill four screw holes in them. Can you advise what preparation we need to do and what paint to use?

A. Wet sand the existing coating using 220 grit sandpaper to profile for repainting. Wipe clean and then fill screw holes using RepairCare Dry Flex SF then apply a full coat of Resene Galvo-Prime and finish with two coats of Resene Lustacryl CoolColour of the topcoat colour.

November 2019

Q. We are about to re-stain the outside of our house and I was wondering if Resene has a specific cleaning product to wash the old stain? The water blaster is too rough on it.

A. We recommend Resene Timber and Deck Wash. Treat areas of mould/algae with Resene Moss & Mould Killer diluted and used to label directions.

November 2019

Q. I have purchased an 'arts and craft' house built in 1920s, which has a lounge with rimu panelling and battens. It has been coated with a lacquer/shellac, which has crazed.

I am wanting to have this removed as the wood area is dark. I have tried meths which does remove it however it takes a long time and is a big job. Can you suggest another treatment that will remove this lacquer easier and faster?

A. You could try a paint stripper or an orbital sanded fitted with 180 grit sandpaper.

November 2019

Q. What is the difference between ceiling paint and wall paint? I have some touch ups to do but seem to have only the ceiling paint in the cupboard.

A. Ceiling paints are formulated at a near flat gloss level and do not contain a high resin content, this means that these paints have very poor burnish resistance and some may be removed by wiping.

Wall paints are generally formulated at a higher gloss level and on a different resin system. The selection of resin and the higher gloss level does give the paint film better resistance to cleaning.

November 2019

Q. We are painting arrows to classes to help students get around the school without being lost. What type of paint would be best to use and how do we clean the concrete?

A. The concrete would need to be cleaned down using Resene Paint Prep and Housewash diluted and used to label directions.

Then you can paint the design using Resene Lumbersider or Resene testpot paint (2 coats). 

Do you think that the paint finish needs to be slip resistant?  If yes, then you could use SRG Grit in the paint or change to Resene Non-Skid Deck & Path.

Q. I have a few little runs where I applied a bit too much Resene Lustacryl on my window frames. How soon can I sand these off and touch up?

A. Wet sand with 220 wet and dry sandpaper, it is difficult to sand fresh waterborne paint. Then spot prime with Resene Quick Dry and re apply the Resene Lustacryl topcoats.

November 2019

Q. We have just painted our kitchen countertop with Resene Waterborne Smooth Surface Sealer, then Resene Acrylic Undercoat and topcoat in white. Once well dried we have spot dabbed Resene testpot paints in three colours. What is the best water-based clear to seal the countertop to a kitchen surface hard finish? We do have a tin of Resene Qristal ClearFloor 1K Waterborne Flooring Urethane, could that be used as the sealer?  Does it yellow?

A. I recommend Resene Concrete Wax.

Q. I have applied two coats of concrete stain to my pavers 10 days ago. In places they are shiny and feel sticky during the heat of the day. They were plain concrete and water blasted at 3,000psi prior to staining. It was an extremely hot day when I stained them. I have enough stain to apply a third coat on a cooler day if this will help?

A. Two coats of concrete stain should be sufficient. The ideal outcome is to have little or no stain sitting on top of the concrete, this may be why you are seeing stickiness, probably worse when the surface is heated by the sun.

I would not apply a third coat. Leave the stained surfaces to weather for a month or so to see if the stickiness dissipates.

Q. We have a footpath at about 1 in 8 to 1 in 12 slope.  It is a glazed paving brick and can get quite slippery.   Do you have a non-slip brush or roller applied coating?

A. Resene Non-Skid Deck & Path would be the coating we would recommend for foot traffic areas.

The challenge is to achieve adhesion to the glazed tile surface. The product we have is Resene Waterborne Smooth Surface Sealer.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene Non-Skid Deck & Path.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the tiles.

Q. We are in the process of painting our house. We have a COLORSTEEL® roof which is 15 years old, the screw heads are rusty, how do we treat these before painting? Or do we need to replace the screws with new ones before painting?

A. Rusty screws are a tricky one. Typically when we talk about painting over previously corroded surfaces we need the surface to be thoroughly prepared prior i.e. all corrosion removed before priming. With screws etc it's almost impossible to prep them sufficiently.

Often roofers or roof painters will just replace them as it's actually a lot quicker and easier to do this.

If you were to leave in place you'd want to ensure that all loose rust etc is removed as best you can. Then prime with two coats of Resene GP Metal Primer before painting your roof.

November 2019

Q. I'm looking for a polyurethane type coating for some indoor plywood cabinetry. I've used solventborne in the past, never used water based - not sure if waterbased is as tough, and up to the job?

A. Waterborne polyurethanes do provide a good level of protection and durability however typically the solventborne options are still a notch above when it comes to durability.

The benefits of waterborne coatings are that they are low odour, can be washed up in water, don't yellow the timber like solventborne products do, and they will still provide a good level of durability.  However, if durability is something that's top of mind for you, you may want to stay with a product like Resene Qristal Clear.

November 2019

Q. I need to paint the concrete floor of my food chiller. I have already degreased the floor but I need to know what type of paint to use.

A. The chiller would have to be brought up to and maintained at room temperature for paint application and curing.

For best results diamond grind to remove existing coating and to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping. Then apply a seal coat of Resene ArmourBond and finish with three coats of Resene Aquapoxy for Flooring.

The full system cure will require five days, maintain the chiller at room temperature and good ventilation for this time frame.

November 2019

Q. I would like to whitewash a wooden floor. It probably has been oiled some years ago (old shipping container).   Can I use your whitewash for interior and what prep would be needed?

A. Ensure the existing clear coating is grease free and thoroughly sand to profile for recoating. Ensure an even wet film thickness is applied to avoid overlapping marks.

Then apply Resene Colorwood Whitewash and over coat with two coats of Resene Aquaclear. Ensure an even wet film thickness of the Resene Colorwood Whitewash is applied to avoid overlapping marks.

November 2019

Q. Which product would you recommend for sealing an oldish concrete floor (in a barn conversion) prior to laying carpet, please? The floor was laid prior to waterproofing requirements.

A. Diamond grind to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping. Then apply three coats of Resene HydraBlock, thin the first coat 15% with water.

November 2019

Q. I have a small area that has a concrete floor. I would like to make it Food Safe as I need to manufacture in this room. What product would you recommend that are food safe?

A.  We recommend Resene Aquapoxy for Flooring. If wet slip resistance is not required omit the addition of the Resene SRG Additive to the second coat, This will also make cleaning easier.

Check using the water splash test for the presence of a curing membrane, water splashed onto the concrete should immediately darken the concrete and be absorbed. If the water is not immediately absorbed and the wet concrete does not darken then this indicates the presence of a curing membrane.

If the water splash test indicated the presence of a curing agent then diamond grind to remove the existing curing membrane and to achieve a uniform surface profile similar to 180 grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

Q. I want to line bathroom walls in grooved plywood with a semi-gloss paint finish. As I am trying to minimise interior toxins/VOCs I was hoping to use untreated plywood and seal it against moisture penetration. The plan was to envelope coat with Resene Quick Dry then finish the surface with two coats of Resene Lustacryl, however I see in the technical info that prepping with Resene TimberLock is recommended for this application. Given that Resene TimberLock has very high VOCs would I be better off going for a treated plywood in the first instance and then just priming with Resene Quick Dry? What is the healthiest option that will still withstand a bathroom application?

A. I would go with the treated ply option.

November 2019

Q. I need an external pine treatment for a commercial landscape job for a retirement village. We have some timber bollards, timber posts, and timber signs, pine. The signs are tall, so using Glulam posts.

What stain or oil or treatment would you recommend, that will give a nice rich natural timber colour to pine, in both Glulam and standard posts (125mmx125mm)? The concern is having the laminated posts look too different than the other posts, they should be the same colour, but I'm ok with highlighting the laminated parts as is only natural.

A. For a stain option Resene Waterborne Woodsman stain (two coats).

November 2019

Q. I am using waterbased undercoats and Resene Enamacryl on our outside wooden windows. My problem is that the paint is lifting off the glazing putty starting from the glass junction with the putty.

A. Unfortunately the adhesion of waterborne paints to glass is not as good as a solventborne system. Water collects at the gloss/putty interface and if this is like total immersion of the waterborne system and this causes the paint in contact with the gloss to lift. Once this occurs the process will continue.

The only way to overcome this is to ensure that a solventborne undercoat is used to paint over the putty/glass interface and then only topcoat the enamel undercoat with the waterborne paint, suggest a change to Resene Lustacryl for the topcoat may also be beneficial.

November 2019

Q. Just a question on Resene Swimming Pool paint, on the tin it says that the paint must be left for 1-2 weeks after application.  What would be the minimum number of days we could leave it before we start to fill our school swimming pool?

A. The delay in refilling after completion of painting is to ensure that all solvent has been released from the applied coating and then removed from the pool. The solvents we use in the product are heavier than air so they will sit on the lowest point in the pool.

When this happens the coating's cure is not only compromised if the pool is filled the solvents can become dissolved in the pool water, something to be avoided at all costs as this will pose a potential health issue to users.

Q. Can you recommend a transparent matt coating for Prime Panels American White Oak veneer?  This will not be subjected to UV or moisture.

A. We recommend Resene Aquaclear Natural.

November 2019

Q. I am wondering what paint would be best for our outdoor front fence that would last as long as possible. The fence is made from treated pine rails and untreated cypress posts. The fence will experience full sun and 40°C+ plus rain, hail, frost. We want to paint it black.

I have a pergola which has become weathered over the last 10 years or so. It had been painted white but now has moss and lichen growing on it. I intend to get it waterblasted, primed and painted. What type of paint would you recommend to address future moss and lichen problems?

A. Best long term system is a coat of Resene Wood Primer and two coats of Resene Lumbersider, use the Resene CoolColour™ version of the topcoat colour if selecting dark colours.

The Resene Cool Colour system will not render the painted surface cool to touch, but the cool colour system will reflect more heat than the same colour made on non-cool pigment technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. The cool colour system will reduce but not eliminate heat related stress on the substrate.

Q. I have a pergola which has become weathered over the last 10 years or so. It had been painted white but now has moss and lichen growing on it. I intend to get it waterblasted, primed and painted. What type of paint would you recommend to address future moss and lichen problems?

A. Paint will not control of bio growth. Suggest you apply Resene Deep Clean diluted and used to label instructions at the beginning spring each year, if growth is heavy may be a second application at the beginning of autumn as well.

Q. We have some outdoor signs laser cut from Grade 316 Stainless Steel Plates (finish: polished) that require site painting to a satin/slightly reflective black. The project is located in a geothermal area. Could you advise on appropriate products and specification for this use?

A. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, poor air-circulation or industrial contamination environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide which, because of the greater volume of the iron oxide, tends to flake and fall away. Stainless steels contain sufficient chromium and other rare metals to form a passive film of chromium oxide which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.

There are over 150 grades of stainless steel, of which 15 are most commonly used. There are a number of systems for grading stainless steel. The most commonly used grades are 304 and 316.

304 Stainless is a Cr-Ni general purpose stainless steel. Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 the molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

Where long term corrosion resistance is the prime requirement stainless steel is best left unpainted.

If damage to the protective oxide layer occurs stainless steel can show tea staining.

Tea staining can be described as: discolouration of the surface of stainless steel that does not affect the structural integrity or the longevity of the material. Visually it is a discolouration of the metal surface, which tends to follow the “grain” of any surface finish. Although unpleasant to look at, it is not a serious form of corrosion. Aesthetically it is unacceptable so the following information is designed to help you understand its causes and institute a maintenance plan to keep your stainless steel looking better for longer. Tea staining of stainless steels occurs most commonly in coastal areas and becomes progressively worse the closer you get to water (note that most of New Zealand is considered a coastal area). Other factors such as pollution, higher temperatures, surface finish, (the smoother the better and more highly polished) and humidity can also increase the tea staining effect.

Painting is usually undertaken for aesthetics only. The stainless steel surface needs to be abraded to produce a mechanical key for a paint system and this damages the protective oxide layer.

Step 1: Scrub down using Resene Roof and Metal Wash

Step 2: Lightly abrade the surface using a very fine sandpaper e.g. 320 girt sand paper or a red 3M poly pad. Care must be taken to minimise damage or scratching the surface as scratch marks may telegraph through the paint system.

The paint system to use is Resene Armourcote 220 applied to achieve a dry film thickness (DFT) of 75 microns, two coats of Resene Uracryl 402  Black applied to achieve a total DFT of 100 microns, and finish with a full coat of Resene Uracryl 402 UVS Clear to achieve a DFT of 50 microns.

Q. I want to polyurethane plywood furniture; what do you recommend? I understand waterbased stuff is available now, only ever used the smelly solvent stuff in the past.

A. Our waterborne polyurethane clear is Resene Aquaclear.

It is based on a self-cross linking resin system, cures to be a hard wearing finish, not as hard as a solventborne clear but certainly suitable as an alternative clear system.

November 2019

Q. I want to paint a Dominator (COLORSTEEL®) 4 panel garage door. The paint and door is in good condition (just faded). Changing colour from Terracotta to Off-White. What do you recommend please?

A. Wash down using Resene Paint Prep and Housewash diluted and used to label directions to achieve a chalk free surface. Apply a full coat of Resene Pre-Coated Steel Primer and finish with two coats of Resene Summit Roof or Resene Sonyx 101.

November 2019

Q. How can I achieve a glitter effect?

A. There are a few versions of this.  We have a range of metallic paints – Resene FX Metallic - and they are the main thing that customers use to get a 'glittering' metallic style effect. They come in a range of colours from precious metal type colours to bold metallic colours and some nature inspired ones.  You apply a basecoat of solid colour first then the Resene metallic over the top.

We also have Resene FX Pearl Shimmer which is a light pearlescent effect which you can add onto your painted finish and it gives a little sparkle - sort of like 'space dust'.

Another way we have seen a 'glitter effect' done in children's art is to apply a clear Resene finish or a paint finish and then sprinkle glitter into it.  As the paint dries the glitter will stick.  Usually this option is only used for children's art as it isn't that practical as an ongoing finish.

November 2019

Q. Can Resene Colorwood Whitewash be applied direct to polyurethaned timber flooring?

A. Resene Colorwood Whitewash can be applied over an interior existing clear varnish if the existing clear is sanded to profile.  Then you can coat it.

November 2019

Q. I am currently doing the design for a Firth brick veneer cladding house and it is advised that we clear seal the cladding, I was just wondering what product/system you would recommend?

A. We recommend Resene Concrete Clear as a clear seal coat option. The first coat must be the gloss.

November 2019

Q. Do you have an etch primer suitable for stainless steel and galvanised steel.  This will be topcoated with an acrylic exterior paint.

A. Yes Resene Vinyl Etch. Etch primers are developed to achieve adhesion and not long term corrosion so if you have galvanising we would recommend priming with Resene Galvo One, Resene Galvo-Prime or Resene GP Metal Primer.

November 2019

Q. I am looking for a stone textured style paint and think I will use Resene Sandtex which recommends applying by crows feet.  Please can you help me get this application right?

A. Apply a solid base coat colour of Resene Lumbersider then using a wide brush apply the Resene Sandtex in an X pattern with overlap of each X.  Continue this over the whole area.

November 2019
