Abstract
A method of treating wood to provide anti-stain and anti-decay waterproofing properties includes applying to the wood a water solution having about 1.3 to 2.75 weight percent of a quaternary ammonium compound, about 1 to 2 weight percent of a hydrated starch solution, about 2.5 to 5.0 weight percent of a slack wax water emulsion and about 90 to 95 weight percent water. The solution may be created by establishing a first mixture of hydrated starch solution, slack wax emulsion and water and subsequently admixing the quaternary ammonium compound with a first mixture. Preferred solid concentrations of the emulsions are provided. A wood waterproofing composition contains about 1.3 to 2.75 weight percent of a quaternary ammonium compound, about 1 to 2 weight percent of a hydrated starch solution, about 2.5 to 5.0 weight percent of a slack wax emulsion and about 93 to 97.5 weight percent water. The waterproofing composition concentrate, prior to admixture with the quaternary ammonium compound, contains the hydrated starch solution and slack wax emulsion. An adhesion promoter, such as an acrylic polymer, may be employed. Other additives may be employed.
