Abstract:
1. A surface covering consisting of: a multilayered composite material, wherein the multilayered composite material further includes a plurality of vertical perforated lines and a plurality of horizontal perforated lines, the vertical and horizontal perforated lines forming a grid, the structure of said multilayered composite material facilitating the convenient hand tearing of said surface covering through said grid; and further wherein the multilayer composite material further comprises (1) a top facing layer of polymeric film, wherein the top facing layer comprises single or multiple layers of a thermoplastic film and (2) a non-slip, non-adhesive bottom layer of unsupported polyvinyl chloride foam, wherein said top facing layer reinforces the dimensional stability of the unsupported foam and further still has sufficient tensile and tear strength to inhibit failure of said surface covering during tearing and the unsupported polyvinyl chloride foam is configured to tear, along with the polymeric film, along the vertical and horizontal perforated lines.
