How To Paint Granite Countertops White

Granite is a beautiful natural stone that is often used in countertops. However, over time, granite can become stained or discolored. If you are looking to update your granite countertops without replacing them, painting them white is a great option. Here is a step-by-step guide on how to paint granite countertops white:

Materials You'll Need:

TSP cleaner
Clean cloths
Sandpaper (120-grit and 220-grit)
Tack cloth
White primer
White paint (specifically designed for granite or stone surfaces)
Polyurethane sealer
Paintbrush or roller
Sanding sponge or sanding block

Step 1: Clean the Countertops

The first step is to clean the countertops thoroughly. This will remove any dirt, grime, or grease that could interfere with the paint's adhesion. To clean the countertops, mix 1/4 cup of TSP cleaner with 1 gallon of warm water. Use a clean cloth to apply the solution to the countertops, and then wipe them down with a clean, damp cloth. Allow the countertops to dry completely before proceeding.

Step 2: Sand the Countertops

Once the countertops are clean, you need to sand them to create a smooth surface for the paint to adhere to. Start by sanding the countertops with 120-grit sandpaper. Use a sanding sponge or sanding block to avoid scratching the countertops. Once you have sanded the countertops with 120-grit sandpaper, switch to 220-grit sandpaper and sand the countertops again. This will create a smooth, even surface for the paint.

Step 3: Wipe Down the Countertops

After sanding the countertops, use a tack cloth to wipe down the countertops and remove any dust or debris. This will help the primer and paint adhere better to the countertops.

Step 4: Apply Primer

The next step is to apply a coat of primer to the countertops. Primer helps the paint adhere to the countertops and prevents the paint from absorbing into the granite. Use a paintbrush or roller to apply a thin, even coat of primer to the countertops. Allow the primer to dry completely before proceeding.

Step 5: Paint the Countertops

Once the primer is dry, you can start painting the countertops. Use a paintbrush or roller to apply a thin, even coat of paint to the countertops. Allow the first coat of paint to dry completely before applying a second coat. You may need to apply multiple coats of paint to achieve the desired coverage.

Step 6: Seal the Countertops

Once the paint is dry, you need to seal the countertops to protect them from wear and tear. Use a polyurethane sealer specifically designed for granite or stone surfaces. Apply a thin, even coat of sealer to the countertops using a paintbrush or roller. Allow the sealer to dry completely before using the countertops.

Step 7: Enjoy Your New White Countertops

Once the sealer is dry, you can enjoy your new white countertops. With proper care and maintenance, your painted granite countertops will last for many years to come.
