Finishing & Protection

It is recommended that a finish is applied to all surfaces, including ends, before installation. The type of coating will be determined by the final finish and appearance desired.

Prefer the silver-grey look?

Sioo Impregnation quickly provides a clean wood surface with an attractive silvery-grey finish often desired but seldom achieved from new wood or damaged applications.

What is weathering?

There is a risk involved when leaving wood exposed to the elements. During the weathering process wood can appear unsightly as the material can blacken due to moisture getting into the fibres and pulling out tannins and extractives. Finish protects the wood from moisture absorption and UV degradation.
