How to Seal Stone Countertops
- 1). Test the surface of your countertop to see if it is sealed. Place a few drops of water onto the countertop. Wait approximately 15 minutes. Wipe off the water with a clean rag. If the surface darkened, it needs to be sealed. Allow the darkened area to dry completely.
- 2). Apply a liberal amount of water-based impregnating stone sealant to the surface of the countertop with a paint pad. Allow the sealer to sit on the surface of the countertop approximately five minutes.
- 3). Wipe off the excess sealant with clean rags. Allow the surface to dry before use.
