ABSTRACT:
A flexible wall covering material and a process for manufacturing includes applying a thin foam layer to a flexible fiberglass fabric web. An adhesive is then applied to the foam layer to bond therewith, and the web is passed under hoppers which drop small aggregate and fine aggregate successively onto the adhesive layer. The web is then drawn through an oven which heats and cures the adhesive, securing the aggregate to the web. The web is passed under a vacuum hood which removes the loose aggregate, and a sealer is sprayed onto the aggregate surface of the composite. The sealer is dried by radiant heat to seal the stone material and emphasize its color, and the web composite is wound onto rolls for subsequent use as a wall covering, and especially an exterior wall covering.
