Abstract
This invention is directed to a method of coating to make a resilient, flexible surface covering that has a wear surface having stain, mar, scuff, and soil resistance. The improved resilient surface covering comprises (a) a resilient support surface; and (b) a resilient wear surface adhered to the resilient support surface, the resilient wear surface comprising an underlying wear layer base coat and an overlying wear layer top coat adhered to the wear layer base coat, the wear layer base coat comprising a flexible, thermoset, polymeric composition having a flexibility such that the wear layer base coat passes a 1 inch mandrel diameter face out mandrel bend test when applied at a nominal dry film thickness of 1.0 mil over a flexible 80 mil underlying substrate, the wear layer top coat comprising, a hard, thermoset, UV-curable blend of acrylic or acrylate monomers, the wear layer top coat having a glass transition temperature of greater than 50.degree. C. The present invention is also directed to a method of making a resilient surface covering that has a strengthening layer that provides strength, toughness, resistance to breakage, especially resistance to tearing, and resistance to deformation, especially resistance to indentation and sliding gouging. The strengthening layer resilient surface covering comprises (a) a resilient support surface comprising an unfoamed strengthening layer comprising a vinyl resin and a polymerized, cross-linked monomer, with the proviso that, the strengthening layer is not disposed between two foam layers; and (b) a resilient wear surface adhered to the resilient support surface.
