Abstract
An improved method of impregnating wood with a preservative is achieved by using halogenated solvents as carriers for the preservative or other wood treating chemicals and removing the carrier from the treated wood by treatment with steam. Benefits derived from this process include fewer steps, substantially complete removal of solvent, and the production of a natural appearing wood product having a surface suitable for painting.
