How to Seal Granite Countertops

how to seal granite countertopsYour granite countertops are beautiful and when you properly maintain them, they will stay that way for a very long time. If you enjoy having beautiful granite in your kitchen, and don’t want to pay hundreds of dollars a year to maintain them, you should learn how to seal your granite countertops. There are many different types of granite. Each type has a varying degree of permeability to liquids, bacteria, and germs. If yours is porous, you need to learn how to seal granite the right way. This will help prevent stains and help keep germs out of your kitchen. Water based granite sealers are easy to use. They penetrate the surface of the stone quickly and can deliver long-lasting protection. We will explain how to seal granite countertops with an economical sealant and with a premium brand. That way you will know how to do it and what to expect with each method.

Do I need to Seal My Grout?

If your granite countertops absorb water, then they need sealing. This is most often done upon installation, and then once every 2-3 years. A simple test suggests you leave a wet rag on the countertop. After 10 to 15 minutes, and you see a slight discoloration in the granite, it has absorbed some of the water. (With sealed granite, water beads on the surface.) Sealing granite countertops in your kitchen is very important because this is where you prepare food. Learning how to seal your granite countertops will keep them free from germs and bacteria as well.

1. Clean your countertops – The first step is to simply clean your counter. Some websites suggest that you use a stone cleaner. In my opinion, a simple cleaning solution in a spray bottle (like vinegar, or a mild cleaning agent) will work great. When cleaning granite countertops, it is important to use a non abrasive cleaner. A bit of warm soapy water will also work great for cleaning and disinfecting your countertops. After your granite countertops are thoroughly cleaned, please allow them several hours dry. With a premium sealant, they suggest you wait up to 24 hours for the granite to cure before applying your granite sealer.

It is possible to apply your granite sealant with a brush, but for most types of granite a spray bottle will work just fine. I prefer to use a spray bottle because it is also easier. You don’t have to worry about scrubbing the sealant into your granite countertops. The Granite does the work for you. After 15 to 20 minutes, your first granite application gets absorbed. With Premium Granite Sealant: using a brush and a high quality stone sealer will allow you to seal your granite for up to five years. Carefully apply to the entire surface. Reapply regularly as-needed to prevent the granite sealer from drying, and to give you an even penetration over the entire surface. Allow up to 30 to 40 minutes for the granite sealer to absorb. Extra porous surface may need more application.

3. Multiple applications until your granite is no longer porous – All you need to do is simply spray it multiple times and allow 15 to 20 minutes between each application for the sealer to soak into the stone. Once you apply the granite sealer, and it no longer absorbs any of the sealer, then you know that the sealing process is complete.

4. Wipe off the excess residue – when the surface of the granite is no longer permeable, it should stay wet. When this happens, simply wipe off excess residue with a damp cloth. Premium: After the sealer dries, remove remaining granite sealer with a dry towel. Wait for at least 4 hours before touching the surface. This allows the sealant time to set up properly. ** Premium Granite sealers need 24 to 72 hours to fully cure.

Congratulations, you have learned how to seal granite countertops and can now do it on your own!.

Your granite countertops should be completely sealed. This will last you about 2-3 years, depending on how often you use your countertops, and the quality of the granite sealer that you used.

Below are Common Granite Sealing Questions People Have:

How often should you seal your Granite?

granite sealingOn average, sealing granite counter tops takes place once every 1-2 years if you are using an economic, spray-on brand. A premium brush-on brand should last you up to 5 years. If you have a marble countertop, you will want to re-seal it about once every six months. With a premium sealer, it should last 2-3 years. Resealing granite countertops lasts longer with a premium sealer.

How Much Does Sealing Granite Countertops Cost?

Most types of granite sealers are not expensive and can easily be applied. One quart of n granite sealer will cost around $40 and should give you enough sealant to cover around 300-400 square feet of granite countertop. **One quart of Premium Stone and Granite Sealer only covers 80 to 100 square feet.

Can I do it myself?

Absolutely. The process of sealing your granite is as easy as cleaning it. When you apply a granite sealer, you want as much of it as possible to soak into your countertop. The goal is to make the porous granite surface absorb as much of the granite sealant as possible. (This prevents other materials from soaking in later.)
