Granite is strong, durable and moisture resistant. And while you don’t have to seal it when it’s used as a countertop, it’s recommended.
Why Seal Granite?
Granite, like many natural stones, is porous. At least once every three years, a sealant should be applied to prevent staining from oils, water and other liquids. If your granite countertop is properly sealed, liquids and oils will bead on top of it rather than seep into the stone. Grease can stain granite as can colored liquids such as grape juice and wine.
Sealing granite can also prevent etching, caused by cleaners or acidic foods such as lemon juice.
The Benefits of Sealing Granite Countertops
Once your granite countertops are sealed, they will be easier to clean and you won’t need to use as many chemicals to clean them. Plus, you’ll have a more hygienic surface. Granite is porous and can harbor bacteria; sealing helps cut down on the cracks and crevices where bacteria can live.
While we don’t recommend using products with bleach, ammonia or acids to clean granite, you can clean surfaces with mild soap and water and natural stone cleaning products.
Not all pieces of granite have equal porosity, so you may have to seal some pieces more frequently than every three years. Dribble water on your countertop to test if it needs sealing. If the water beads, it’s fine; if it soaks in, you should seal it
