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.

What is claimed is: 1. A cementitious veneer comprising: a magnesium oxysulfate compound including magnesium sulfate, magnesium oxide, sodium hexametaphosphate, phosphoric acid, and water; and a 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. 2. The cementitious veneer layer of claim 1 wherein the polyvinyl polymer mixture comprises polyvinyl alcohol fibers boiled in water with butylene carbonate. 3. The cementitious veneer layer of claim 2 wherein the water is distilled water. 4. The cementitious veneer layer of claim 2 wherein the water is microclustered water. 5. The cementitious veneer layer of claim 2 wherein the magnesium oxysulfate compound comprises approximately sixty volume percent of the cementitious veneer mixture. 6. The cementitious veneer layer of claim 1, wherein the magnesium oxysulfate compound consists of, by percentage of volume, 0.04% to 0.08% sodium hexametaphosphate, 0.06% to 0.17% phosphoric acid at a concentration of 75% to 85%, 40% to 46% magnesium sulfate, 30% to 35% magnesium oxide, 1.3% to 1.4% distilled water, 2.5% to 3.25% hollow granular fly ash spheres, and the cementitious composition consists of, by percentage of volume, 1.2% to 1.9% hollow granular fly ash spheres, 77% to 85% Calcium Sulfate Hemihydrate and Portland Cement, 13.5% to 14% distilled water, and 1.25% to 2.5% of the mixture of polyvinyl polymer and butylene carbonate.
