Granite makes a wonderful addition to any home. Granite effortlessly blends practicality with stunning beauty, making it a popular high-end countertop material in many households. Granite’s appeal and durability can increase a home’s value and resale ability.
While granite can practically last forever, sealing your granite countertops is necessary for its upkeep and longevity. Granite needs to be sealed, or it will lose some of its fortitude and shine.
Thankfully it is easy to seal a granite countertop. Sealing granite protects the stone from tough stains, scratches, and bacteria that can build on the surface of your countertops. It also protects it from deteriorating over time.
So, whether you’re a first-time granite countertop owner or a seasoned pro looking to seal your granite countertop, get ready to protect your investment with this quick and easy guide to sealing your granite countertop.
Why seal a granite countertop?
Granite is porous, meaning it has tiny, open spaces on its surface that can be permeated. Its porous material makes granite susceptible to bacteria and stains.
Sealants help to infiltrate into the stone, creating a protective layer and barrier against bacteria and dirt.
Even if you recently had a granite countertop installed and sealed, sealants are known to wear down over time, allowing liquid and food residue to permeate the granite’s surface.
If you avoid sealing your granite countertop, it can become more vulnerable to damage, making it harder to clean and maintain.
Therefore, sealing your granite is a necessary part of its upkeep.
Step-by-Step Guide on How to Seal a Granite Countertop
Supplies you’ll need
- Granite Sealant – I used the Aqua Mix Sealer’s Choice Gold
- Microfiber cloth or rag
- Dish soap
- XL Cleaning Sponge
Step 1 – Clean the granite surface
The first step is to remove all items from the countertop to prepare for cleaning. Clean the granite countertop’s surface with a damp cloth and dish soap to wipe away any dirt, grease, and food residue on the countertop.
Once you are done, allow the entire counter to dry. The entire surface must be dry to apply the sealant in the next step.
Step 2 – Apply the sealant
Apply the sealant to the countertop.
Use an XL grouting sponge to apply it liberally and generously to the granite, letting it penetrate and absorb onto the surface. Apply the sealant with the sponge in a circular motion. Make sure the sealer is evenly distributed, covering the entire granite surface.
Then give the sealant 5 minutes to work its magic on the granite surface. If the sealer does not penetrate the surface within 5 minutes, use absorbent paper or a cotton towel to remove the excess sealer.
Please note that not all sealers are created the same. If you use a different sealer than the one recommended above, read the manufacturer’s label before applying the sealant. Your sealer of choice may require a different way of applying.
Step 3 – Apply a second coat of sealant (optional)
If a second coat is needed, allow 30 minutes of drying time between the first coat before applying the second coat.
Step 4 – Test the Surface
Allow the Sealant to dry for 2 hours after the final coat. Check to see if the surface is completely sealed by pouring water droplets on the surface. If the water gets absorbed, then you should apply another coat.
Step 5 – Let the Sealant dry
Allow the sealer to dry completely before using your granite kitchen countertops. Give it 4-6 hours before using the clean granite counters.
Tips When Using Granite Sealer
- Open the windows to allow air circulation and proper ventilation when applying sealer.
- Try to test the absorbency of the countertop before applying the seal. If your counters absorb oils or liquids, a sealer is necessary.
- Make sure that your granite countertops are clean and free from any stubborn stains or dirt before sealing.
- Do not apply the sealer too thickly; ensure it is distributed evenly on the granite surface.
- Give the sealer time to dry before using your countertops.
- Always choose a high-quality sealer that is specifically designed for granite countertops.

However, having a handy commercial cleaner helps preserve the granite countertop best. Here are a few cleaners that are great for everyday use.

How often do you need to seal a granite countertop?
The frequency of sealing your granite countertops depends on several factors, such as the type of granite, how often you use the countertops, and the sealer you use. Generally, you should seal your granite countertops every one to three years.
Perform a granite water test every few months to see if your granite countertops need sealing. The simple water test requires you to leave a few drops of water on the countertop for 15 minutes. If the water beads up and doesn’t absorb into the stone, your granite countertops don’t need sealing. If a small amount of water starts to absorb into the stone, it’s time to seal your granite countertops.
