Abstract
The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.

A method of manufacturing a floor or wall covering comprising the steps of
- (a) forming a substrate by
- (1) providing a non-woven polyester base layer;
- (2) applying a liquid vinyl acetate emulsion pre-coat to the base layer;
- (3) drying and curing the pre-coat layer on the base layer;
- (4) applying a first polyvinyl chloride layer to the vinyl acetate emulsion pre-coat layer;
- (5) applying a non-woven mat to the first polyvinyl chloride layer;
- and
- (6) applying a second polyvinyl chloride layer to the mat;
- (b) passing the substrate through an oven to cure the polyvinyl chloride layers;
- and
- (c) laminating a prestabilized woven polyvinyl chloride layer to the substrate to form a face layer for the covering.
