Melamine Countertop Durability

Melamine

• Melamine countertops -- often called laminate countertops -- begin with a layer of wood pulp known as kraft, followed by a middle layer of decorative paper that contains the color and pattern of the countertop. These are topped by a clear top layer. The middle and top layers contain the clear resin melamine. The layers are pressed together under high temperatures and pressure to form sheets of laminate. This process makes the material stronger and more durable.

Durability

• Laminate countertops are long-wearing and strong. Depending on how well an owner takes care of the countertop, it can last for at least 20 years, according to the home improvement website Service Magic. Guarantees of up to 40 years are offered by some companies.

Potential Problems

• While laminate countertops are durable, they're far from indestructible. The surface can be sliced if a cutting board isn't used when chopping food. Scratches show more on dark counters because the melamine in the outer layer takes on a white appearance when cut, contrasting with the color beneath. The counter can also chip if a heavy or sharp object drops on it. Harsh chemicals, including oven cleaners and bleach, will also damage the counter. Unlike stone counters, laminate countertops are not susceptible to damage from acids such as lemon juice. Matte finishes will show fewer flaws than glossy ones.

Maintenance

• To avoid damage to a countertop containing melamine, don't cut directly on the surface or place a hot pan on it. Wash the counter with a gentle cleanser as needed. Don't use abrasive scrubbing cleaners. Scratches and chips on badly worn counters can be filled with a special plastic and sanded for smoothness. The entire counter is then resealed.
