Abstract
A method of applying a coating, such as a substantially waterproof coating, to a wood surface using a collapsing foam coating material. The material is initially sprayed onto a recessed wood surface, whereupon the resin material foams and collapses over a relatively short period of time into a film coating or layer that penetrates and seals the wood surface. A delivery system for applying the coating is also disclosed.
