Cultured marble is a blend of polyester resin, catalyst, fillers and pigments in precise amounts, mixed thoroughly. This mixture is cast into highly polished open molds that have been coated with a clear gel coat. This gel coat is formulated to achieve a tough, durable, waterproof, non-porous, and transparent surface, which is very resilient and easy to maintain. Depending on the finishing process used, the gelcoat also provides the glossy surface that adds luster to the final product.
Cultured marble countertops lead the way as one of the most popular materials for resurfacing bathroom vanities. Available in a host of different colors and at a much more reasonable price than real marble and granite, homeowners may even discover that the benefits of cultured marble countertops outweigh those of many other materials.
