A cementitious composite article incorporating a powder coating on at least one surface is provided. The composite article includes a surface treatment adapted to facilitate application of the powder coating onto the article. The surface treatment can include modifications to surface porosity, surface, and/or application of a sealer to the surface so as to make the cementitious surface more conducive to powder coating. One method of manufacturing the cementitious composite article includes first applying a sealer coating to a surface of a fiber cement substrate, partially curing the substrate to a gel-like state, applying a powder coating to the article, processing the article to a curing device in which the powder coating and sealer coating are co-cured to form a hardened film.
What is claimed is: 1. A cementitious composite article, comprisinga cementitious substrate having a first surface;a powder coating layer including a plurality of a finely divided, heat fusible material; anda surface interface comprising a separate sealer coating applied thereon, wherein the surface
What is claimed is: 1. A cementitious composite article, comprisinga cementitious substrate having a first surface;a powder coating layer including a plurality of a finely divided, heat fusible material; anda surface interface comprising a separate sealer coating applied thereon, wherein the surface interface is interposed between the first surface and the powder coating layer, wherein the surface interface consists essentially of inorganic filler in the form of a slurry or powder mixture comprising a cementitious material for modifying the first surface porosity and facilities application of said powder coating layer to the substrate.
