Abstract
A method of protecting wood through enhanced penetration of wood preservatives includes providing a solution including (a) at least one amine oxide, (b) at least one organic wood preservative and (c) a buffering agent. The solution preferably has a pH of about 7 to 10. The solution is applied to the surface of the wood after which, with or without intervening storage, the materials are activated to effect enhanced penetration of the organic wood preservative into the wood. One may effect application at a solution temperature of about 30 to 75° C. and preferably about 50 to 60° C. to effect activation at a higher temperature and high relative humidity. In a preferred practice, the wood may be heated before and/or after application of the solution. The solution is also disclosed as a product.
