How to stain weatherboards

Staining weatherboards with Resene Woodsman penetrating oil stain

Resene Woodsman is available in a waterborne and solventborne version and results to date show that Resene Waterborne Woodsman has better durability than its more traditional solventborne variant. It is also available in a greater range of colours and is the product used in the Resene Woodsman testpots.

Before starting

  1. With the exception of new weatherboards, treat moss and mould with Resene Mould & Moss Killer (see Data Sheet D80) – this is best applied using a knapsack garden sprayer. Care should be taken to avoid plants etc.

  2. Scrub old and/or weathered timber using Resene Timber and Deck Wash (see Data Sheet D813) and a hard bristled scrubbing brush to remove mould residue, detris and contaminants. If the timber is new wash it with Resene Timber and Deck Wash to condition. This will allow the stain to penetrate more easily as well as removing any surface contamination, fingermarks, dirt etc.
    Do not waterblast as this will gouge and damage the timber.

  3. Use a good quality brush, such as a PAL Legend, in a size that you are comfortable with. We recommend the use of painter’s gloves as Resene Woodsman can be surprisingly difficult to remove from skin.

  4. Ensure surfaces such as decks and window frames are protected using drop sheets and masking tape.

  5. Ensure the Resene Woodsman stain is stirred thoroughly before use and every 10-15 minutes during application.

  6. Decant from larger pails and cans into smaller more manageable containers, such as the Resene Paint pot.

  7. Please take the time to carefully read through the instructions on the label. More information including Data Sheets and Safety Data Sheet/s (SDS) can be found on the Resene website.


Start from the top of the weatherboards and work your way down the side of the house. Stain a single board at a time.

Depending on the size of the area to be stained either stain the underside first or stain both the underside and flat edge as you progress along.

Apply the stain evenly and liberally using the brush to work the stain into the timber.

End boards should be completed either at the beginning or end of each section. If staining vertical boards including fence pailings, work from the top down completing one board at a time.

The key to achieving the best finish is to maintain a wet edge because stains are semi-transparent and any overlapping of dried stain will be darker in colour than the surrounding areas and therefore noticeable. This is more obvious in lighter colours.

Once fully dry, usually after two or three hours, apply a second coat.

While not always necessary, particularly when restaining, a third coat will prolong the life of the stain and should be considered if your home has areas that are hard or costly to access.

Resene CoolColour™ technology is available in some of the darker Resene Waterborne Woodsman colours and the benefits are maximised by using three coats.
