How to Refinish Granite Countertops

Refinishing granite countertops is a cost-effective way to restore their original luster and extend their lifespan. Over time, granite surfaces can become dull, scratched, or stained due to regular use and exposure to household chemicals. Fortunately, with the right tools and techniques, you can revitalize your countertops without the need for a full replacement.

This guide on how to refinish granite countertops will walk you through the steps to bring back the beauty and durability of your granite countertops, ensuring they remain a stunning centerpiece in your kitchen or bathroom.

Why Refinish Granite Countertops?

There are several reasons why you may need to refinish your granite countertops. As mentioned, regular wear and tear can lead to scratches, dullness, and staining. Additionally, exposure to heat or direct sunlight can cause the granite to fade over time.

Refinishing is also necessary if you want to change the color of your countertops. Instead of replacing them with new ones, refinishing offers a more budget-friendly option.

What You Will Need

Before starting the refinishing process, make sure you have all the necessary tools and materials on hand:

Cleaning Solution: 

A mild dish soap or granite cleaner will do the job. Avoid using harsh chemicals, as they can damage the surface.

Sandpaper:

Choose a fine-grit sandpaper (around 400-600 grit) to remove any scratches and imperfections from the surface of the granite.

Polishing Compound:

This is essential for restoring the shine to your countertops after sanding.

Sealer:

A high-quality sealer will protect your newly refinished countertops from stains and spills. Look for one specifically designed for use on granite surfaces.

Soft Cloth:

You will need a soft, lint-free cloth to apply the cleaning solution, polish, and sealant.

8 Step-by-step Guidelines on How to Refinish Granite Countertops

Step 1: Clear and Clean the Countertops

Start by removing all items from the countertops, including appliances, utensils, and decorations. Once the surface is completely cleared, use a soft cloth and a cleaning solution, such as a mild dish soap or granite cleaner, to thoroughly clean the granite. Gently scrub the surface to remove dirt, grease, and any residue.

Pay special attention to stained or sticky areas and ensure they are completely cleaned before moving to the next step. Rinse the countertop with clean water and dry it with a lint-free cloth to leave a spotless surface ready for refinishing.

Step 2: Repair Any Damage 

Inspect the countertop for any visible cracks, chips, or deep scratches that need to be addressed before refinishing. For small chips or cracks, use a granite repair kit or an epoxy resin designed for stone surfaces. Follow the instructions on the product to fill in the damaged areas, ensuring the surface is smooth and even. For deeper scratches, you may need to sand the area gently with fine-grit sandpaper until the scratch is no longer visible. 

Once the repairs are complete, allow time for the epoxy or repair material to cure fully according to the product instructions. Properly repairing damage at this stage ensures a seamless and durable finish during the refinishing process.

Step 3: Sand the Countertops

Using fine-grit sandpaper (around 400-600 grit), gently sand the entire surface of your countertops in a circular motion. This will help remove any scratches, stains, and dullness from the surface. Make sure to keep the sandpaper wet at all times to prevent it from clogging up and damaging the countertop.

Once you have sanded the entire surface, wipe it down with a damp cloth to remove any residue. Repeat this step as needed until the surface feels smooth and looks uniform.

Step 4: Apply Polishing Compound

After sanding, your countertops may look dull and lackluster. To restore their shine, apply a small amount of polishing compound onto the surface. Use a soft cloth to buff the entire countertop in circular motions, focusing on areas that need more attention.

Keep buffing until you achieve the desired level of shine. If needed, add more polishing compound and continue to buff until you are satisfied with the result.

Step 5: Clean Countertops Again 

Once the polishing is complete, it’s important to clean the countertops again to remove any leftover residue from the polishing compound. Use a soft, lint-free cloth and a mild cleaning solution or granite cleaner to wipe down the surface thoroughly.

Rinse with clean water to ensure no polish remains, as this could interfere with the sealing process. Dry the countertops completely with another lint-free cloth, leaving the surface pristine and ready for the next step.

Step 6: Seal the Countertops

Using a high-quality granite sealer, apply a thin layer onto your countertops with a soft cloth. Make sure to cover the entire surface evenly, including edges and corners.

Follow the product instructions for recommended drying time, and apply a second coat if necessary. This will ensure maximum protection against future stains and spills on your newly refinished countertops.

Step 7: Let the Countertops Cure 

After applying the sealer, it’s crucial to allow the countertops to cure properly to ensure long-lasting results. Follow the curing time recommended by the sealer manufacturer, which typically ranges from 24 to 48 hours. During this period, avoid placing items on the countertops or exposing them to water, heat, or heavy use.

Allowing adequate curing time helps the sealer bond effectively with the granite surface, providing optimal protection and enhancing the durability of your refinished countertops. Patience during this step ensures a flawless and resilient finish.

Step 8: Maintain Your Refinished Countertops

To keep your newly refinished countertops looking like new, it’s essential to follow proper maintenance practices. Regularly clean with a mild dish soap or granite cleaner, avoid harsh chemicals and abrasive cleaning tools, and wipe up spills immediately.

Additionally, reseal your countertops every 1-2 years to maintain their shine and protect against stains. With proper care and maintenance, your refinished granite countertops will continue to look stunning for many years to come.

Following these step-by-step guidelines on how to refinish granite countertops will help you successfully refinish your granite countertops and achieve a beautiful, like-new finish. With the right materials and techniques, you can transform your worn or damaged granite countertops into a focal point of your kitchen or bathroom once again. So don’t hesitate to try this cost-effective solution for restoring the beauty of your granite surfaces and enhancing the overall look of your space. Happy refinishing!
