DETAILED DESCRIPTION One embodiment of the present invention is a synthetic stucco system that is waterproof and durable. The present invention includes a method of applying the synthetic stucco system of the present invention comprising the application of an elastomeric coating to a base substrate or insulation board and allowing the elastomeric coating to cross-link and fully react. A conventional finishing coat can then be applied to the elastomeric coating, thereby providing a pleasing and durable stucco appearance to the structure. The present invention also includes a composition comprising a base substrate or insulation board, a polymer coating on the base substrate or insulation board, and a finishing coat. Another embodiment of the present invention includes a method of applying a synthetic stucco system in a single step. This embodiment of the present invention includes adding to the polymer that is to be applied to the base substrate or insulation board, fillers and coloring agents that provide a texture and color to the applied polymer that is similar to stucco. Fillers and additives that can be used with the present invention include, but are not limited to, sand, glass, fibers, calcium carbonate, coal, granite, silica, clay, talc, mica, pigments, ceramics, flame retardants, (e. g. , phosphonic acid, methyl-,(5-ethyl-2-methyl-1,3,2-dioxaphosphorinan-5-yl)methyl methyl ester, phosphonic acid, methyl-,(5-ethyl-2-methyl-1,3,2-dioxaphosphorinan-5-yl)methyl ester, P,P'-oxide sold under the trademark ANTIBLAZE N, Phosphoric acid, 2,2 bis(chloromethyl)-1,3-propanediyl tetrakis(2-chloroethyl)ester, ethanol, 2 chlor-, phosphate (3:1) sold under the trademark ANTIBLAZE 100 and tris(monochloropropyl)phosphate sold under the trademark ANTIBLAZE 80 by Albright & Wilson, Glen Allen, Va. , albright-wilson. com), multicolored quartz, sea shells, recycled products, fiberglass. In this embodiment of the present invention, the polymer is applied to the base substrate or insulation board, preferably by spraying, at a thickness that provides the desired aesthetic qualities and strength characteristics
