Can you paint cca

The timeline for painting KDAT wood is considerably more condensed. Start with primer formulated for exteriors, and make sure that the manufacturer lists the coating as suitable for use on pressure-treated wood. Note that, while priming and painting pressure-treated wood may be easiest with a paint sprayer, opt for a brush or use both in combination if the job entails detail work. Having primed the wood—and having allowed sufficient time for the primer to dry it should take no more than a day —move on to applying your top coats.

You should expect to do two. Avoid using oil-based paint here; on pressure-treated wood, latex performs much better. Yet another option is to allow the wood to weather and become gray, and then to coat it with a protective sealant. Of course, sealant must also be reapplied, but many consider the job to be less demanding than repainting, which often entails scraping away parts of the old finish.

Due to the unstable nature of Wet, Unseasoned Treated Pine, there will likely be some movement in the timber during this air drying period. In some cases LOSP treated timbers will have already been pre-primed. Depending on the compatibility between your chosen Alkyd Oil Based Primer and the subsequent two top coats you may be able to use an Acrylic water based paint.

Test Report Mean coefficient of friction on wet surfaces 0. Stain finish systems will require a third coat after summers. Note that these products have not been tested for slip resistance and will not conform to the Building Code in accessways. Resene do not recommend clear finishes over exterior timber exposed to direct sunlight. Clears offer little UV protection of the timber surface. Early loss of adhesion will be caused due to UV breaking down the fibres on the timber surface.
