Abstract: An inventive method for producing a laminated molded countertop includes the steps of placing the surface laminate material into a mold, applying a layer of polyurethane foam to an interior side of the laminate material, applying a reinforcing member, if necessary, on top of the layer of polyurethane foam, applying a second layer of polyurethane foam over the reinforcing member and closing the mold. A resultant molded article has an exterior surface laminated thereto due only to the forces generated by the polyurethane foam during the time when it is expanding and solidifying.
