Cultured marble is an engineered composite used for sinks, countertops, windowsills and other kitchen and bath surfaces that are exposed to moisture. The material is particularly valued for countertops cast with integral sinks. Cultured marble is a blend primarily of crosslinked polyester resin and calcium carbonate filler, which is cast into a mold of the desired shape. The mold is sprayed with a gel coat soon before the mixture is poured in; the gel coat will give the product a glossy finish and seal the slab. A small amount of contrast pigment and resin is swirled onto the surface of the mixture before it is poured in to a mold and allowed to cure. Once removed from the mold, the swirled contrast pigment produces a visual effect resembling a marble surface. Cultured marble has a different composition and manufacturing process from engineered quartz. Contrasting pigments are not considered as part of this CP.
