Abstract

A coating system, a method of coating a substrate, and a coated substrate (e.g., a coated cement fiberboard article) include one or more latex polymers, an aliphatic epoxy resin system, optionally a silicate additive, and optionally one or more olefinic compounds and an initiator. The coating system may be applied in one or more layers and may be applied to all the surfaces of the substrate (e.g., the front side, back side and edges of a board). The coated substrate may then be coated with other optional coatings, e.g., decorative or protective topcoats.
