Timber Types

Most timber species, be they hardwood or softwood can be coated but for the best results refer to the timber guide.

Avoid using green timbers that have not been seasoned or kiln dried. Green timber is more likely to warp and crack as it dries. Oil and Stains will not penetrate fully into green timber, which will reduce their lifespan.
