To seal granite countertops, follow these steps:
1. Clean the surface: Use a mild cleaner and a soft cloth to remove any dirt or stains from the countertops. Make sure they are completely dry before proceeding.
2. Choose the right sealer: Select a high-quality granite sealer that is specifically designed for countertops. Read the instructions on the product carefully.
3. Apply the sealer: Pour a small amount of sealer onto the countertop and spread it evenly using a clean cloth or sponge. Work in small sections to ensure complete coverage.
4. Let it absorb: Allow the sealer to absorb into the granite for the recommended time stated on the product. This will help protect the stone from stains and spills.
5. Wipe off excess: After the recommended time, wipe off any excess sealer from the surface using a clean, dry cloth. Make sure there are no streaks or residue left behind.
6. Repeat if necessary: Depending on the type of sealer used, you may need to repeat the process to achieve maximum protection. Follow the instructions on the product for any additional coats.
By following these steps, you can effectively seal your granite countertops and maintain their beauty and durability for years to come.
Granite countertops are a popular choice for their durability and low maintenance. However, to keep them stain-resistant, it’s important to periodically seal them.

Granite is an igneous rock made up of quartz, feldspar, mica, amphiboles, and other minerals. As the molten material cooled, tiny gaps formed between the individual crystals, creating pores in the rock. In its natural state, granite absorbs liquid through those pores.
While granite is relatively nonporous compared to other countertop materials, it still requires a sealer to make it stain-resistant. The sealer creates a barrier that prevents absorption of food and liquids.
How Often Should You Seal Granite?
Typically, granite countertops require sealer once a year. However, various factors can affect the frequency, such as the porosity of the granite, regular wear and cleaning routines, and the type of sealer used.
Professional-grade sealers may last up to ten years, while others may only provide protection for six months to three years. If you’re unsure which sealer to use, ask the installer or look for a product containing fluorocarbon aliphatic resin, which provides five to ten years of protection.
Performing the Water Test
To test if your granite needs to be sealed, pour one or two tablespoons of water on the surface in different areas. If the water beads up after three minutes, your granite is properly sealed. If it soaks into the pores and leaves a dark mark or ring after fifteen minutes, it’s time to reapply sealer.
Applying sealer too frequently won’t harm the granite, but it may create a hazy film.
How to Seal Granite in 4 Easy Steps
Step 1: Gather Materials
Before you begin, make sure you have all the necessary materials:
The materials needed for cleaning granite countertops include microfiber cloths or clean rags, granite cleaner (or a homemade solution of liquid dishwashing detergent and isopropyl alcohol in a one-pint spray bottle), granite sealer, rubber gloves, a flat utility knife (optional), extra fine steel wool (optional), and granite stain remover (optional).
To prepare the surface, start by checking for hard water deposits near the faucet. Use a flat utility knife to cut away any deposits and then rub off any remaining residue with extra fine steel wool. Next, check for stains and use a granite stain remover according to the manufacturer’s instructions. Clean the entire countertop with a granite cleaner or the homemade solution, removing all items from the surface and wiping it with a dry cloth. Allow the surface to dry for 24 hours before sealing.
To apply the sealer, start with a small test area and follow the instructions on the sealer label. Apply the sealer and rub it evenly on the surface with a clean cloth. Allow the sealer to dry for 15 to 20 minutes and then wipe off any excess sealer with a dry cloth. Apply a second coat if recommended by the manufacturer and allow the sealer to cure for 48 hours before using the countertop.
To maintain the countertop, wipe up spills as they occur with soapy water and dry the surface. Use the remaining granite cleaner on a monthly basis to keep the countertop looking new.
FAQ
1. What is the purpose of sealing granite countertops?
Sealing granite countertops is important because it helps protect the surface from stains, spills, and damage. Granite is a porous material, which means that it can absorb liquids and become stained if not properly sealed. Sealing creates a barrier on the surface of the granite, preventing liquids and stains from penetrating into the stone. It also helps to maintain the natural beauty and shine of the granite.
2. How often should granite countertops be sealed?
The frequency of sealing granite countertops depends on several factors, such as the type of granite, the level of usage, and the type of sealer used. In general, it is recommended to seal granite countertops every 1 to 3 years. However, some darker and denser granite may require less frequent sealing, while lighter and more porous granite may need to be sealed more often. It is best to follow the manufacturer’s recommendations and perform a water test to determine if resealing is necessary.
3. Can I seal granite countertops myself?
Yes, you can seal granite countertops yourself. There are many granite sealers available on the market that are designed for DIY application. Before sealing, make sure the countertop is clean and dry. Apply the sealer evenly using a clean cloth or brush, following the manufacturer’s instructions. Allow the sealer to penetrate the granite for the recommended time, then wipe off any excess. It is important to work in small sections and avoid overlapping to ensure an even application. Always test the sealer on a small, inconspicuous area before applying it to the entire countertop.
4. What should I avoid when sealing granite countertops?
When sealing granite countertops, it is important to avoid using harsh or acidic cleaners, as they can strip away the sealer and damage the surface of the granite. Avoid using products that contain bleach, ammonia, or vinegar, as these can dull the shine and cause discoloration. It is also important to avoid placing hot pots or pans directly on the countertop, as extreme heat can cause the sealer to break down. Instead, use trivets or hot pads to protect the surface.
5. How can I tell if my granite countertops need to be resealed?
You can perform a simple water test to determine if your granite countertops need to be resealed. Sprinkle a few drops of water on the surface and wait for about 15 minutes. If the water beads up and does not penetrate the granite, then the sealer is still effective. However, if the water absorbs into the granite and leaves a dark spot, it is an indication that the sealer has worn off and it is time to reseal the countertops. It is important to address any staining or damage promptly to prevent further issues.
