Are Granite Worktops in the Kitchen Paintable? (What You Should know)

How to paint  granite worktops

My visitors keep on asking this many times whether they can paint over granite countertops in the kitchen.

Well, to be frank, granite comes with its own natural beauty and it is not easy to cover that with paint.

IMO, painting countertops is not a recommended method to change their look because it will only last for a short time before peeling off, and also the paint job will be very difficult to achieve a professional-looking finish.

But if you still insist, then you can go ahead but with a few conditions.

  • Firstly, the countertop must be well-sealed so that the paint can adhere to the surface better.
  • Secondly, you will need to use a high-quality primer and paint so that it can last longer.
  • Lastly, you should seal your freshly painted job with the right kind of sealer to protect the paint job and look shiny.

With that being said, below I will detail the step-by-step guide on how to paint granite countertops:

Painting Granite Countertops

Countertop painting is not an easy task, but it can be done if you really want to change the look of your kitchen.

Here are the steps you can follow:

Step 1) Clean

The first thing that you need to do is to clean the countertop thoroughly. You need to make sure that there is no grease or dirt on the surface before painting.

Start by cleaning the surface with a degreaser and scrubbing it well with a brush. Once you are done, rinse it off with water and let it dry completely.

Step 2) Sand the Worktop

After cleaning, the next step is to sand the granite countertop. This will help to rough up the surface so that the paint can adhere to it better.

You can use sandpaper with a grit of 120 to 150. Sand the surface in the same direction as the grain. This will make the finish look like marble.

Once you are done, wipe off the dust with a clean cloth.

Step 3) Apply Painters Tape

The next step is to apply painter’s tape around the edges of the kitchen countertop.

Be sure to use good quality tape so that the paint does not bleed through.

This will also help to create a clean line when you are painting.

Step 4) Apply the Primer

Once you have applied the painter’s tape, the next step is to apply a primer to the surface.

Kilz Adhesion primer worked very well for me and you can use the same for priming the glossy surfaces such as granite.

The good thing is you can even have it tinted to match the color of paint you are using.

This will help to reduce the number of coats you need to apply.

Apply the primer evenly on the surface with a brush or roller. Let it dry completely before moving on to the next step.

Step 5) Paint the Surface

After the primer has dried, the next step is to apply the paint to the surface.

Acrylic latex paint is a fantastic option because it can withstand heat and moisture, which are two of the features to consider when painting your granite worktop in the kitchen or bathroom.

If you want, you can alternatively use epoxy or acrylic paint that will have an in-built staying power for the future.

Just keep in mind that if your granite top is near a fireplace in the kitchen, always test the heat resistance of the paint you are using.

Once you are ready with the correct paint type, you are ready to paint the surface in long and even strokes as you have applied the primer.

Be aware that it will take a long time for the paint to dry fully before proceeding with the next step of the procedure.

Also, you may not be able to use your fireplace for a few days and your cooking time will also be restricted for a few days until the procedure is finished.

Step 6) Seal Up Your Paint Job

After the paint has dried, it is time to protect your new paint job with a sealer.

Keep in mind that ordinary wood sealers such as polyurethane, lacquer, etc. will not work for granite because they will not be able to stand up to the heat and moisture in the kitchen.

So, make sure you use a good quality granite sealer that’s designed specifically for stones, marbles, and granites.

Some of the best high-quality ones include:

  1. Weiman Granite Sealer
  2. Granite Gold Spray Sealer
  3. Black Diamond Stoneworks Sealer

Be sure to follow the instructions on the label carefully before applying it to the surface.

After you have applied the sealer, let it dry completely. Once it is dry, your newly painted granite countertop will be protected and you can use it as usual.

And that’s it!

Your granite worktop is now ready to take on anything your kitchen can throw at it.

Precautions and Tips

To keep yourself protected there are a few things you should keep in mind before starting the project. These include:

  • Work in a well-ventilated area because the fumes from the primer and paint can be dangerous.
  • It is also a good idea to wear gloves to protect your hands from the chemicals.
  • In addition, I would also recommend using a respirator or mask to avoid inhaling the fumes.

Using Granite Countertop Paint Kit – Is it Worth?

Granite countertops can be permanently sealed with a factory seal from a few businesses; other companies, on the other hand, provide kits that may permanently seal your granite counters.

If you want to achieve a professional-looking paint job, then using a do-it-yourself granite countertop paint kit is a good idea.

These kits are highly rated and include almost everything you need to complete the granite paint job.

Giani brand paint kit, for example, includes sponge cleaner, mineral paint, primer, topcoat, and more.

You can pick from the varied color options such as White Diamond, Bombay Black, and Slate.

Some of these kits even contain a video tutorial so that you can follow the instructions easily and paint your granite countertop like a pro.

The only drawback of these kits is they can be sometimes complicated to follow, and costly.

Also, not all of them are readily available through typical outlets, but with only specialty shops.

Overall, if you are looking for an easy and hassle-free way to paint your granite countertop, then using a kit is the way to go and get incredible results.

Make sure you get one from a reputable brand to avoid any issues.

How Often Should You Seal Your Granite Countertops?

It is recommended that you seal your granite countertops once in 2-3 years to keep them looking new and protected from stains.

If you live in an area with hard water, then you may need to seal them more frequently.

You can easily check if your countertop needs to be sealed or not by performing the water test.

To do this, simply pour a few drops of water on the surface and wait for 10 minutes.

If the water droplets darken the granite, then it means your countertop needs to be sealed.

On the other hand, if the water droplets simply sit on the surface without darkening it, then your countertop is already sealed and you don’t need to do anything.

Should Your Kitchen Worktop Match with Bathroom Countertops?

Matching countertops with your kitchen island or throughout the house is often a personal choice.

Some people like to have all their countertops in the same material to create a cohesive look.

Others like to mix and match different materials and colors to create a more unique and interesting look.

When recoloring, the good thing is you can even paint over existing granite countertops if the paint is in good condition.

However, it’s recommended to peel away and sand any existing paint nicely before painting over the granite.

This will ensure that the new paint job adheres properly and doesn’t chip or peel away.
