Abstract
A surface covering product is disclosed which includes a layer of fused embossed PVC material on a substrate and a layer of transparent or translucent thixotropic material substantially covering the fused PVC layer and filling the embossed area of depression in the PVC layer. The surface covering product is made by applying the thixotropic material to the embossed surface of the PVC material and wiping off at least a portion of the thixotropic material. In one embodiment, a film of thixotropic material of substantial or minimal thickness remains on the fused PVC material. In another embodiment, the thixotropic material is completely wiped off the undepressed area of the fused granular material. The PVC material is preferably a granular material such as a stencil vinyl fine material. In one embodiment, the thixotropic material is a layer of minimal thickness substantially covering the stencil vinyl fine material.
