The present invention provides a waterproofing wood preservative system comprising a waterproofer selected from the group consisting of an alkyl amine oxide, an alkyl acetoacetate, and a waterproofing quaternary ammonium compound and a biocide comprising at least one biocidal quaternary ammonium compound wherein said waterproofing quaternary ammonium compound is a C12-C30 alkyl or C6-C20 aryl-substituted alkyl, C12-C30 alkyl quaternary ammonium composition and said biocidal quaternary ammonium compound is a C8-C12 alkyl or C6-C20 aryl-substituted alkyl, C8-C10 alkyl quaternary ammonium composition. Said wood preservative system offers protection against both biological and physical decomposition of wood, as for example, that occurring in long term-weathering. |
