How to Correctly Seal Your Granite Countertops
Granite countertops are made from natural stone materials, which means they will last a long time, but only if sealed correctly. If you know how to properly seal the surface of your countertops, they will be extremely heat and strain resistant and be very easy to clean. Although granite has so many benefits when it comes to kitchen counters, having to get a professional countertop sealer to come in every year can be expensive and annoying. We want to help you understand the 'why' and 'how' to stone countertop sealing so you may know everything you need to know to maintain your beautiful rock surfaces.
It all starts with using the right sealant. There are so many options and low-cost methods you can look into, but the fact is, it comes down to how deep the surface sealer penetrates the stone. The deeper the sealant goes, the better protected it will be from heat, stains, and bacteria. With a more effective sealant your countertop can go that much longer without another sealing job. This also makes your day to day job easier in the kitchen as you’ll only need to clean the granite with a mild detergent and a wet cloth.
What you want to look for in a sealant is one that falls into the class of “impregnating stone sealers”. Our stone countertop professionals not only know how to plan and install, but are great consultants on maintaining the granite or quartz as well. If you have questions on the best sealer to use for protecting your counters, feel free to ask one of them and they will be happy to show you the best ones we recommend. The one that is known for great sealing results is Tenax Hydrex Impregnating Stone Sealer. This is what many of us professionals use to seal the countertops and it’s proven to deter mold and bacteria for a long-lasting, healthy counter surface. If you find yourself worried about staining the counter with oil, this is definitely a product for your kitchen.
When doing further research on what sealant to use for your granite, quartz, or marble countertops, look for these features:
You want a sealant that will not only dry within 10 minutes but one that will dry invisible on the surface without altering look, and colour of the actual stone surface. Ensure that the product your buying has enough coverage for your countertop. A good coverage amount is 160 sq. ft. per quart of stone sealing product. As long as the product has these features and is meant to deter water-based liquids and oils, it will do the trick for you.
Now that you’ve figured out the product you need, let’s talk about how to correctly utilize it on your stone slabs…
Step 1: Make sure that you thoroughly clean the granite countertop with a mild countertop cleaner. Ensure that it dries before moving on to the next steps.
Step 2: Once you have verified that the counter surface is dry, get a dry cloth (preferably lint-free) to apply the sealer.
Step 3: Put the impregnating sealer onto the cloth and begin wiping the sealer onto the natural stone countertop surface. As you do this, be sure to evenly distribute the sealer along the entire counter, including corners and edges of the cut and installed granite.
Step 4: Allow the first coat to dry for about 10 minutes and then begin applying a second coat in the same manner.
Step 5: Now, you wait. It’s important that you don’t use your granite or quartz countertop to prepare food for 24 hours as it takes this long for the repelling effect to be accomplished on the stone surface.
When this is completed you can rest easy knowing that oil stains or heat marks will not be an issue moving forward. Be sure to test the sealant every few months with a few drops of water. If the water doesn’t bubble up, but seems to soak into the granite stone surface, be sure to apply a new sealing coating. Generally, once a year should do the trick.
Congrats! You now know how to protect and maintain the beauty of your granite. May you enjoy your stone countertops for decades to come!
