Abstract
A building material having a durable exterior finish comprising a fiber cement substrate laminated with a fluorohydrocarbon protective film. The protective film provides the fiber cement substrate with resistance to weathering and maintains the surface texture of the underlying fiber cement substrate while providing an aesthetically pleasing and uniform pre-finish on the exterior surface. The protective film is bonded to the fiber cement substrate using an adhesive composition comprised of a one-component moisture cure polyurethane or polyurea adhesive composition having a reactive isocyanate compound or a two component polyurethane or polyurea composition.
