Everything You Need To Know About Sealing Granite Counters


Sealing granite counters is a process that will allow your granite countertops to shine like new and have a long-lasting life. Many homeowners take into consideration the maintenance granite tops require when weighing the different countertop material options. Although it does require some maintenance, granite is still very much worth it because the natural stone adds value and beauty to your home.

Granite countertops are made of different types of stone and quartzite. The many variations in the materials used to make granite make it ideal for use in a wide range of environments. Granite slabs are designed to be durable and strong. The material is also highly resistant to everyday stains and other scuffs. Keeping your granite countertops looking perfect all the time, however, takes more than just cleaning occasionally. But with the right resealing methods, you can keep them looking brand new for years to come.

Is Granite Porous?

Is granite porous? This is one of the top questions asked by homeowners looking for great quality countertops for their kitchen and bath. Kitchen remodeling can be a bit pricey so it is important to do your research and ask a professional natural stone expert all the questions you have prior to making your final decision on the kitchen counters you want. Granite is indeed a porous stone that requires sealing to prevent staining from liquids and harm from regular use. But how do you know whether it is time to reseal your granite countertops again? You can perform the water test on your counters to conclude whether you do in fact need to reseal them.

The Water Test To Determine Whether You Need To Seal Granite Countertops

If you are wondering whether your counters need to be sealed all you have to do is perform this easy and simple water test. Follow the steps below:

  • Take 1/4 of a cup of water and pour it on your granite countertop
  • Time the water from the moment it was poured till the moment it was absorbed
  • If the water did not absorb and it repelled instead then this means you do not need to seal
  • If the water absorbed and there is now a dark spot then this means you should seal granite counters

Granite Water Absorption

  • Instant water absorption means you should apply a few layers of granite sealant annually and wipe off spills quickly
  • 4 to 5 minute water absorption means you will need multiple layers of sealer but you will only have to reseal it every 3 to 5 years. Before you reapply the sealer make sure to use the water test
  • 10 minute water absorption means you will need to apply a layer of sealer and it may be many years until you will need to reapply
  • 30 minute water absorption or no water absorption at all means there is no need for sealer at this time

How To Seal Granite Countertops

Remember to always test the absorbency of your granite countertops before you seal them. If your counters are absorbing any oils or liquids then a sealer will help prevent any harsh damage to your tops. There is no sealer that is 100% stain proof. A quality sealer will give you enough time to wipe off liquid spills before they stain your countertops. It is important to know that countertop sealer will not make your tops shiny. This is a common misconception. Polishing is what makes your granite counters appear shinier.

Step 1: Perform The Water Test

Refer back to the top of this article to understand and learn how to perform the water test effectively in order to find out whether you will need to seal your granite countertops at this time.

Step 2: Natural Stone Sealer

You will want to search for a sealer made specifically for natural stone so that you will not harm your countertops. Products such as MORETM Surface Care has a great selection of stone-safe options such as the Stone & Quartz Cleaner + Protector. This cleaner can be purchased in any of the Cutting Edge Countertops Showrooms.

Step 3: Read The Sealer Instructions

Make sure to read through the instructions and warning labels just for your own knowing. Instructions change from sealer to sealer so be sure to follow them respectfully.

Step 4: Clean Granite Countertops

Cleaning granite countertops is a step you must take and not forget about before sealing them. Make sure to read the guide above on how to properly clean your granite countertops or visit our countertop care and maintenance page.

Step 5: Apply The Countertop Sealer Evenly

Take the spray bottle and spray a generous amount of sealer on the countertop and let the sealer absorb into the granite stone for about twenty minutes (check instructions on the bottle for a time amount).

Step 6: Wipe Off The Sealer

Sometime you may need to apply the sealer a second time. A second coat is necessary for certain sealers so make sure to read the bottle to get the appropriate information on this! Now grab a clean cloth that is lint-free and wipe off the sealer from your countertops.

Step 7: Do Not Use The Countertop For 48 Hours

After following all of the instructions in this guide and the requests made on the sealer bottle make sure you leave your countertops alone for 2 full days.
