ABSTRACT:
A fiber-cement/plywood surface and method of providing a preformed surface material for flooring, decking, walkways and roadways, more particularly for use with marine dock structures. The method includes applying a coating of a catalized resin material over one surface of a sheet of plywood substructure so as to seal the substructure as the resin hardens, and also coating one surface of a fiber-cement sheet with a catalized resin material and allowing it to harden. A bonding agent, which comprises a catalized resin material mixed with a thickening agent such as mill fibers or finely chopped fiberglass strands, is applied between the two facing resin surfaces of the respective plywood sheet and the fiber-cement sheet, whereby the two sheets are bonded together so as to form a single, somewhat-resilient, weatherproof and wear-resistant structure or panel. An alternative arrangement is also provided wherein the substructure is a thick plastic foam core encased in a fiberglass and polyester resin.
