Abstract
An artificial stone building tile and method. Disclosed is an artificial stone building tile and a method of making the building tile. The building tile has a low density and significant flexibility, and is nailable without cracking. It is made by layers of cement formulations separated by layers of metal mesh. Color batches of cement are prepared and placed in the bottom of a mold, with the color batches becoming the visible face of the building tile.
Claims19
An artificial stone building slab comprising:
- a color layer made up of at least one colored cement mix, comprised of stone powder, cement, pigment and a glue, the color layer configured for placement on a vertical wall surface facing away from the vertical wall surface;
- a metal mesh layer embedded between the color layer and a backing layer;
- the backing layer adjacent to the metal mesh layer, configured for placement against the vertical wall and made up of a stone mix comprised of half stone powder and half stone pieces less than ⅛ inch in size;
- and
- with the artificial stone building slab having flexibility to allow at least 1¼ inches of flex in a 48-inch piece, and a density of approximately 4 pounds per square foot, and a hardness of greater than Mohs 3 to allow sanding of the slab, and the slab being sufficiently resilient to allow nailing without cracking.

An artificial stone comprising:
- a color layer comprising a stone powder, a cement, a pigment and a glue, the stone powder of the color layer having a particle size less than or equal to 200 mesh;
- one or more backing layers including a first backing layer, each of the one or more backing layers comprising stone pieces, a cement, and a glue;
- and
- one or more layers of metal mesh including a first metal mesh layer embedded between the color layer and the first backing layer,
