How to reseal stone countertops

A quality sealer can prevent spills from soaking in, but the sealer must be reapplied every three to five years.

Marble, granite and other natural stones are popular countertop materials because they are beautiful and timeless.

But stone is porous, which makes it vulnerable to stains from oil, water or other liquids. A quality sealer can prevent spills from soaking in, but the sealer must be reapplied every three to five years.

Stone countertops can lose their durability over time. Chemical agitation from general-purpose cleaners can break down the sealer, and everyday use can cause the stone to become discolored or scratched. Resealing a stone countertop will help protect it, and make it more lustrous and easier to clean.

Before you reseal stone countertops, clean the surface thoroughly. If the countertop doesn’t have a glossy finish, sand off the old sealant. Then use tape to cover the surrounding areas that you don’t want sealed.
