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.
