How To Seal Your Granite Countertop

Granite is a beautiful, hard material that looks gorgeous when used for flooring, back splashes and even countertops. The downside with granite is that, although hard, it is a porous material that needs to be sealed to prevent stains. See below for instructions on how to seal granite and how to tell when it need to be sealed.

When To Seal Your Granite

You can tell when your granite needs to be sealed by giving it a quick test with a few drops of water. Add a few drops of water on your countertop and watch to see how quickly it soaks into the granite. If it only takes a few minutes for the stone to become darker where the water was absorbed, it’s time to seal your granite.

How To Seal Your Granite

  1. ​Clean your granite countetop with a granite cleaner, which can be found at most hardware stores if you don’t already have some on hand. Follow the manufacturer instructions, then wipe it dry with a microfiber cloth (so no lint is left behind). 
  2. Allow the granite to dry thoroughly, at least 24 hours. You want the granite to be back to it’s original color before sealing it.
  3. Before applying the granite sealer, be sure to ventilate the area by opening up windows or doors. Also be sure to use rubber gloves to protect your hands.
  4. Test a small area with the granite sealer before applying it to the entire countertop. The sealer should not leave your countertop with a hazy or discolored look. If it does, look for a different sealer to use.
  5. Spray the sealer in small sections of your countertop evenly. It should only be slightly damp, not soaking wet. Allow it to soak into your countertop. Check the manufacturer directions to see how long you should allow it to set on your countertop. Buff it into your countertop using a microfiber cloth, then move onto the next section.
  6. Continue repeating this process until your entire countertop is finished, being sure to apply the sealer evenly all the way across your countertops.
  7. Allow the sealer to cure, which can be anywhere from 24-48 hours depending on the product you used. During this time, you should keep all items off of your countertop and avoid any water or moisture from coming in contact your countertop.

Applying sealer to your granite countertops should be done when needed to help prevent spills, oils and everyday use from staining your countertops. It will keep your counters looking like new and extends the life of your granite.
