Cultured Marble. This type of marble is a great option for those seeking the expensive look of marble at a more affordable price. Cultured Marble is an artificial surface created by combining fiberglass resin, cement and marble dust. This is a very durable and easy to clean surface because it is less absorbent than natural stone marble making it less prone to stains. Marble is a very hard surface (natural or man-made) and this creates a real safety concern because it is a very smooth surface, making it easy to slip and fall. It is very important to treat cultured marble to reduce this safety hazard.
