Sadolin Extra Durable Clearcoat works with the wood by providing a flexible barrier that protects wood from the damaging effects of rain, moisture and sun/UV light. Behaving like a protective skin, Extra Durable Clearcoat will expand and contract with wood to help significantly prevent blistering and flaking.

Sadolin Extra Durable Clear Coat is an ideal on-going maintenance product.

General information



On light coloured woods, Sadolin Extra Durable Clear Coat will impart a light golden colour to the timber. As with all translucent coatings, the final colour and sheen are dependent on a number of factors, including the timber species, colour and cut, and the presence of any existing coating. A trial application is recommended prior to the commencement of work.
