Cultured Marble, Cultured Granite and Cultured Onyx, while man-made, have the look of genuine marble, granite or onyx. Products in this category are manufactured by spraying a “gel coat” on top of a mold that is contoured to the shape of the desired product. Once the “gel coat” has cured, a mixture of resin, pigment, and crushed calcium carbonate are cast on top of the “gel coat”. “Veigning” of the pigment is created by hand or by machine, creating the look of a natural stone.
Cultured marble, granite and onyx products easily meet nationally-recognized standards to resist water, heat, stains, burns, chemicals and everyday wear and tear. Cultured Marble is a Cultured marble, also referred to as engineered marble, is a type of fabricated surface that resembles marble. It is available in many colors. Cultured marble is a mixture of resin and ground marble or limestone. Though it is a less expensive alternative to natural marble, it can provide more tensile strength. Because cultured marble is made with a moulding process, it allows greater design flexibility than with stone. For instance, manufacturers of cultured marble can make a bathroom vanity with integrated bowl (or bowls). This eliminates grout lines around the bowl. The manufacturing process encompasses several steps. One step uses a non-porous gelcoat on the counters and sinks which seals the product and prevents mold and bacteria growth and staining. The process does not use hazardous material.
