Abstract
A composite laminate system for indoor and outdoor applications, comprising a wood layer comprised of a thin plank or veneer. An aqueous, penetrating primer is applied in a first coating to all surfaces of the wood layer, and the primer is designed to prevent and resist decay from bio attack, insects and other intrinsic bacteria, featuring antibacterial and mold inhibiting properties, including a UV inhibitor. A first aqueous nano urethane acrylic coating is applied on all surfaces of the wood layer on top of the primer coating. At least a second aqueous nano urethane acrylic coating is applied to a top surface of the wood layer on top of the first aqueous nano urethane acrylic coating. A polyvinyl chloride (PVC) foam sheeting layer is glued to the wood layer with coatings using a resin adhesive glue layer interposed between the PVC foam sheeting and the wood layer.
