Granite countertops are a luxurious addition to any home. When you install new granite countertops, it is important to make sure that your countertops are properly sealed. Granite sealer is designed to provide the surface of your granite with a layer that is impenetrable by liquids and stains. 

You can seal your granite on your own, but the results will not be permanent. If you’re interested in permanently sealing your granite, contact your local Seal Team One. Our professional sealing process will last a lifetime.

How to Seal Granite Countertops

Before you apply any sealer, be sure to test a small area to see if your granite countertop is in need of resealing. This test consists of dabbing some water on your hand and sprinkling it onto the countertop surface.

If the water droplets stay beaded up, the sealer is doing its job. If the droplets begin to spread and seep into the surface, that tells you your granite countertop is in need of resealing.

There are some steps you should take before applying the sealer. Take all items off of the countertop and wipe it clean of any stains or residue. If you granite counter has deep seated stains, contact a professional to help remove tough stains.

If using a DIY sealant, be sure to carefully read the application instructions on the packaging of the sealer.

Apply a generous coat of the sealer, completely covering the surface. The sealer should take about 15 minutes to absorb into the stone. Then, wipe dry with a clean cloth.

Make sure to not let the sealer dry completely on the surface, as it can leave a hazy residue that can be difficult to remove. But if it happens, apply more sealer and let it sit again for a few minutes before wiping up.
