Why Do I Need to Seal My Granite Countertops?

Protect Against Stains

Granite is natural stone that is porous, and therefore, prone to absorbing moisture and colors that can stain. Liquids like grape juice, wine, and even grease can leave discolored stains on your granite countertops. Granite seal, a thin film, will protect the natural stone from absorbing these stains and leave a smooth finish that is easy to clean.

Protect Against Damage or Chipping

Applying a protective sealant to your granite will also protect the natural stone from harmful chemicals and basic household products such as lemon juice, which can degrade the granite. It can also act as a barrier protector against chipping.

Protect Against Germs and Bacteria

Since granite is porous, it can absorb and harbor bacteria. Filling in the tiny, unseen gaps with a sealant makes a smooth, even surface that’s easier to clean and resistant to bacteria.

Resealing Granite

Recommended frequency to reseal granite varies from less than a year to every 5 years. You can do an easy water drip test to know whether or not it is time to reseal your granite counters. How often you use your countertops will affect how often you need to reseal your granite countertops. The more you deep clean, scrub, or use discouraged products on the granite surface, the more often you will need to reseal your granite. You cannot over-seal granite, so don’t be afraid to seal often. Higher quality and longer-lasting sealants are available, and can extend the life of the protectant seal.
