Abstract: A metal-stone floor or wall covering, more particularly a “hard surface” floor covering is created in plant by stamping large panels from sheet metal with an interlocking reversing notched edge. This allows each large panel to lock into additional panel sufficient to cover a floor area, whereupon the sheet metal in plant is covered with cross linking polymer cement mixed with crushed powdered stone and the resulting slurry is applied over the surface of the sheet metal in a thin layer and allowed to harden. Grout line grooves are carved into the mixed overlay and filled with a latex grout which is then allowed to harden after which, the tile is colorized, and then sealed with a clear coat, dried and shipped to site for bonding in place by beads of a foamed adhesive which allow some flexing of the floor as an integral structure.
