Cementitious veneer and laminate material
First Claim
1. A cementitious veneer structure comprising:
- a substrate to support a molded cementitious veneer layer, wherein the molded cementitious veneer layer is created by mixing;
a magnesium oxysulfate compound including magnesium sulfate, magnesium oxide, sodium hexametaphosphate, phosphoric acid, and water, anda cementitious composition mixed with the magnesium oxysulfate compound to form a cementitious veneer mixture, the cementitious composition including gypsum cement, filler, water, and a polyvinyl alcohol polymer mixture,and wherein the cementitious veneer layer is molded into a panel form and adhered to the substrate within a mold.

Abstract
A cementitious veneer and laminate composition is provided. The cementitious laminate composition includes a substrate, a primer layer applied to the substrate, the primer layer comprising a mixture of polyvinyl alcohol catalyst, Portland cement, and sand; and a cementitious veneer layer applied to the primer layer, the veneer layer comprising a mixture of magnesium sulfate, filler, magnesium oxide, gypsum cement, and polyvinyl alcohol catalyst. The polyvinyl alcohol catalyst comprises a mixture of polyvinyl alcohol fibers dissolved in water and mixed with butylene carbonate. The veneer layer is applied to the substrate and primer layer by means including spraying and manual spreading. The veneer layer can be ornamentally manipulated either before or after curing of the veneer layer. The veneer composition can be formed into laminated tiles or panels for use in building applications.
