TRU-CORE® H3 Clear Azole treated wood and wood products can be painted or stained to meet any outdoor colour scheme without discoloration from the preservative. Kop-Coat Australia recommends the use of high quality oil and latex based paints, stains or water repellent UV protectant coatings, as is industry accepted with treated wood. The wood must be dry and clean prior to applying any finish coating.
If initial cleaning of the treated wood is needed, it is recommended that the project be cleaned with a deck cleaning product and allow to fully dry. At this time, a clear water repellent can be added to the project.
If applied, allow 8-weeks prior to the application of a semi-transparent stain or paint. In no water repellent is added, an oil based stain can be applied to the clean, dry wood in 15-30 days from treatment date.
A water based stain can be applied to the clean, dry wood in 30-50 days from treatment date.
If the wood is left uncoated and without UV protection, the typical colour of the treated wood will naturally weather to a gray color over long-term exposure to the sun.
Users must always conduct their own tests on coatings in inconspicuous areas of the project to determine acceptability of colour, adhesion and appearance. Always follow the manufacturer’s recommendations for proper application of finishes. A topical water repellent may be applied every one to two years.
