Abstract
Disclosed are composite building boards and associated manufacturing methods. The composite boards may include, for example, one or more slurry layers with embedded fibrous mats. An exterior plastic coating is mechanically adhered to the underlying slurry layer. The plastic layer chemically bonds and cross-links with polymer additives within the slurry layer. The result is an integrated polymer matrix with greatly improved durability and surface strength.
