Disclosed is a process for the manufacture of construction board utilizing a polymeric coating for protection. Particularly, the invention relates to the use of polyurea containing coating systems containing either pure polyurea or polyurea systems which include polyurethanes, polyols, polyacrylics, polyethers and the like. The polyurea coating system is to provide protection of construction board from environmental conditions, damage during transport, molds and insects. Moreover, the polyurea coating system can contain additional excipients to provide various properties including insulation, reflection and fire resistance. Additionally, the polyurea system coating system exhibits excellent formulation flexibility and can be incorporated into existing industrial manufacturing processes without slowing down the manufacturing process.
