Abstract
A surface covering includes a base layer and a wear layer. The wear layer is laminated to the base layer. The wear layer comprises a polymeric binder system having wear resistant particles dispersed therein. The wear layer is formed by dispersing a plurality of wear resistant particles into a liquid to form a stable liquid dispersion, blending the stable liquid dispersion into a polymeric resin to form a mixture, and extruding the mixture to form the wear layer.
