The invention relates to coating compositions for use on wood. The coating compositions are specially formulated so that they can be applied to wood prior to the wood being treated with one or more wood preservatives. The coating compositions are sufficiently permeable so as to not hinder the penetration of the preservative(s) into the wood, so the wood will still meet required industry wood preservation standards. The coating compositions comprise at least one binder selected from the group consisting of resin polymer emulsions in an amount of about 30 - 70% by weight, one or more pigments, and one or more excipients selected from the group comprising antifoaming agents, antimould agents, dispersing agents, wetting agents, surfactants, thickening agents, fillers, UV blockers, stabilising agents, anti-tannin agents, and rheological additives. The invention also relates to a method of treating wood wherein the method comprises a first step of coating the surface of the wood with a coating composition of the invention, and a second subsequent step of treating the coated wood with one or more wood preservatives, such as a LOSP, which penetrates into the coated wood. |
