How to Repair a Crack in Your Granite Countertop

In addition to the beauty they bring to your kitchen, granite countertops are easy to care for. Normally, all you need to do is a little cleaning and preventive maintenance. As long as you wipe up spills as soon as they happen and don't place hot pans or pots directly on the surface, your granite countertop should stay in great shape for years to come.

Moreover, as long as a granite countertop is installed correctly, they are very unlikely to crack. On those rare occasions when they do, repairing them is not particularly difficult as long as the crack isn't too large. However, if it's a huge crack or you've actually chipped off a chunk of the material, it's probably time to call a professional such as Quality Stone Countertops.

What You'll Need to Make the Repair

  • Ammonia or Acetone
  • A Two-Part Granite Epoxy
  • Color Pigment for the Epoxy
  • Granite Sealer
  • Clean Cloths
  • Small Tool like a Foam Brush or Palette Knife

Step 1. Mix a quarter cup of warm water with a quarter cup of household ammonia or acetone. Dipping a clean cloth into this mixture, use it to thoroughly clean the crack and its surrounding surface. Use another cloth to dry the service completely. Don't use any products to clean the crack that might affect the granite's finish.

Step 2. Put on gloves before mixing the granite epoxy. Follow the manufacturer's instructions to mix the hardener with the epoxy. Only mix is much as you will be able to use in the following 10 minutes. Otherwise, it will just go to waste.

Step 3. Again using the manufacturer's instructions, mix your color pigment into the epoxy so as to try to match the color of the granite.

Step 4. Use a foam brush, palette knife or similar small tool to spread the epoxy into the crack in the granite. Use a cloth to quickly wipe away any mess or excess. If you allow the epoxy to harden before you do this, it will be very difficult or even impossible to remove it without starting all over again.

Step 5. Apply granite sealer to completely seal the crack. After you apply the sealer, allow it to sit and dry for at least 15 minutes. Then apply a second coat and let it dry as well. Finally, allow the crack repair you just completed to cure for another 24 hours.
