  • Patent number: 5447752
    Abstract: A surface coating composition comprising generally cement, sand, a polymer binder, and water, and a method for applying the composition to a surface. The composition is used to apply an ornamental surface coating onto a pre-existing cementitious surface, or a surface to which a cementitious base layer has been applied. The surface is cleaned with a muriatic acid solution. A flexible plastic template is laid on the surface to define the desired pattern and a thin layer of the composition is applied. The template is removed after the composition is applied. After the composition starts to cure, the surface is wiped with a damp sponge to round off corners and open up surface pores. The surface is sealed after curing. Texturizing rollers may be used to provide a more realistic finish. The coating is tough and durable, and can withstand up to approximately 6,000 psi (about 400 kg/cm.sup.2) pressure.
