Let’s look at how you can reseal your granite countertops and answer a few other pertinent questions below.

Sealing Granite Countertops

Granite is a beautiful stone that comes in a wide range of patterns and colors. It’s one of the most popular and asked for items in today’s kitchens. It’s easy to clean and durable, but is it a maintenance hassle?

Granite arrives at your kitchen already sealed. Over time, though, it will probably need a reseal. Some stones are more porous than others, and some seals are better than others, so this will factor in. It’s not difficult to seal, fortunately. We’ll talk about how often to seal it, how to know if it needs it, and what to seal it with below.

How Often Do You Need To Seal Granite Countertops?

This depends on how well your granite sealed the first go-round. There’s a handy water test you can do to see how often your granite needs sealing. If you put a 1/4 cup of water on the surface and it immediately absorbs, you need to reseal yearly. When it takes 5 minutes to absorb, then you’ll need to reseal every 3-5 years. If it takes 10 minutes, you may need one new coat of sealer, but then it may not need it again for many years. When the water takes more than 30 minutes to absorb, you don’t need to worry about it anytime soon.

Do Installers Seal Your New Granite Countertops?

Generally, the sealing isn’t done at the time of installation, though it might be done at the fabricators or wholesale distributor’s warehouse before installation. There is an easy way to check, however. Does water bead on its surface? If the answer is yes, then your countertop has been sealed.

What Happens If I Don’t Seal My Granite Countertop?

Because stone is porous, it will soak up spills. Light-colored granite discolors easily when darker liquids and semi-liquids spill on to it. Even water can cause staining and discoloration over time. Water often contains minerals and metals which can react with the properties in the stain. Sealing will prevent your stone from soaking up liquids.

How Do I Know If My Granite Is Sealed?

It’s easy to do a water test to check your granite’s seal. Simply pour a small amount, about 1/4 cup, onto the surface of the stone. Let it sit for 15 minutes, then wipe it away. You know the seal is good if your stone doesn’t discolor from the water.

What Do You Clean Granite With Before Sealing?

About 24 hrs before sealing, give your countertops a good cleaning. First, remove everything from the surface. Them mix up a teaspoon of dishwashing detergent, two tablespoons of isopropyl alcohol, and cool water in a pint spray bottle. Squirt the countertop and using a microfiber cloth, wipe in circular motions cleaning the surface well.
