    Abstract: A coated article is provided that includes a cement composite substrate; and a coating system applied to the substrate. The coating system includes a n epoxy-functional coating composition applied to the substrate, and a water -based coating composition, distinct from the epoxy-functional coating compo sition, applied to the epoxy-based coating, between the compositions. A meth od is also provided that includes the steps of: providing a cement composite substrate; applying an epoxy-functional coating composition to the substrat e; and applying a water-based coating composition, distinct from the epoxy-f unctional coating composition, to the epoxy-based coating. The water-based c oating composition used in this method preferably comprises a polymer having one or more functional groups that can react with the epoxy-based coating t o promote adhesion between the compositions.
