摘要：
Disclosed is a composite building board construction. The board includes a set gypsum core and a fibrous mat that is pre-coated with a cementitious layer. A thermoplastic coating is then applied over the cementitious layer. Additives can be added to one or more of the layers to provide enhanced performance characteristics. Also discloses are various manufacturing techniques for applying a hot melt thermoplastic coating to cementitious layer.
