Cultured Marble Is Peeling

What Is Cultured Marble

• Cultured marble combines limestone and crushed marble to create a material that looks like real marble but at a lower cost. A gel coat finish on top of the cultured marble creates a waterproof seal, but this surface is susceptible to scratches and peeling. Pieces made with cultured marble often appear in places with frequent exposure to water, such as bathtub surrounds and kitchen counters.

What Causes Damage

• Physical shocks, especially with sharp objects, can cut through the delicate gel coat layer on top of cultured marble. Over time, daily rubbing against the surface material can wear away the gel coat and create scratches or pits in the surface. Scouring the cultured marble will also damage the gel coat. Excessive heat shocks the material, resulting in cracking.

Fixing the Damage

• To fix worn, damaged or peeling cultured marble, you will need to treat it like a waxed wood floor. Sand down the top with damp sandpaper. A buffer on low speed can gently buff the cultured marble. Finish the surface with a cultured marble polish or paste wax. This should be rubbed into the surface of the cultured marble with a soft cloth. If the damage extends below the surface of the cultured marble, you will need to replace the piece.

Preventing Damage

• Damage to cultured marble surfaces can be prevented through cautious use and care. Avoid using abrasive cleaners, like wire brushes or scouring powders. Soft cloths and gentle cleansers will help prevent damage while cleaning. Avoid splashing hot water on the marble to avoid thermal shock. Regular polishing with a protective coating designed for cultured marble will help keep the gel coat intact and prevent it from peeling or becoming scratched.
