Colour and Surface Protection
As a matter of good practice, any exposed timber, preserved or not, should be protected from the weather. Enhanced weather protection can be obtained through the application a weather resistant finish. Application of a quality clear water repellent or semi-transparent stain is recommended. Alternatively, deck oil can be used to maintain a modern natural look. Always follow manufacturer's recommendations.
Preserved Wood Appearance
Celcurised Timber will initially have a green appearance that highlights the natural variations of the wood; this will weather to an attractive natural honey brown colour before finally fading to a driftwood grey after long term exposure to the sun. Celcure® treated wood products can be painted or stained to match any outdoor colour scheme. Always follow manufacturer's recommendations.
