How to seal your granite countertop

Granite is porous so sealants are recommended to block liquids from seeping into the stone. A properly sealed countertop will cause liquids to bead on the surface.

Liquids with color — like grape juice and red wine — cooking oil ¬and fat can all discolor the countertop.

 

Generally, you should seal most kitchen granite countertops annually. To determine if it’s time to reseal a countertop, dribble some water onto the countertop. If it beads up, great. If the water soaks into the granite, it’s time to reseal.

 

Sealing is pretty straightforward. Get a good-quality granite countertop cleaner that’s designed to resist water and oil-based stains, and some clean rags. Follow the cleaner’s directions first, making sure the granite is dry before you start sealing. Some sealers, such as those with a solvent base, are good for several years [source: Marble Institute of America].

 

When sealing, work in small areas, allowing the sealer to absorb for the recommended amount of time before applying the second application. Then move to another area. Follow the sealer’s recommended amount of drying time (usually several hours or overnight) before using the countertops.
