How to Repair a Cracked Countertop

If you have a small crack or fissure in your countertop, it can be repaired in a few easy steps. Instructions can vary depending on the material. In this article, we'll show you how to fix cracks in natural stone, engineered stone, solid surface and laminate.

Step 1: Assess the Damage
The first step is to determine the length and width of the crack and its position using tape. Damage from small hairline cracks and nicks less than 1/4-inch deep can be repaired by filling.

Step 2: Clean the Area
To prepare the surface for sealing the crack, wash with rubbing alcohol, acetone or a stone cleaner to remove grease, dirt and other debris. This will enable the epoxy to adhere to the surface. Let it dry.

Step 3: Fix the Crack
You'll need to use a two-part epoxy that matches the color of your countertop. Then apply the epoxy to the crack using a putty knife, smoothing out the epoxy until it's even with the rest of the countertop. Use a razor blade to scrape away any excess. Let the epoxy fully dry before moving on to the next step.

Step 4: Sand, Polish and Seal
Use a fine-grit sandpaper to create an even surface. To ensure that the repair blends in with the rest of the countertop, apply a polish specially formulated for natural stone. Finally, use a sealant suitable for natural stone countertops. It'll help prevent stains and additional cracking or chipping around the repaired area.

Step 1: Assess the Damage
The first step is to determine the severity of the crack. Small nicks and cracks can be repaired yourself. If it's a large crack, call the professionals.

Step 2: Clean the Area
Use acetone or a cleaner that's specially formulated for quartz countertops. Follow the manufacturer's directions for application. Let it dry completely before moving to the next step.

Step 3: Fix the Crack
Tape off the affected area. This will prevent the epoxy from spreading to the rest of the countertop. Select an epoxy that matches the color of your countertop. Apply thin, even layers of the epoxy to the crack and carefully spread it using a toothpick or small wooden stick. It may take 24 hours for the epoxy to dry. Follow the manufacturer's instructions for your particular product.

Step 4: Sand and Seal
Remove the tape and any excess epoxy. Use a fine-grit sandpaper to ensure that the filled crack matches the rest of the countertop. To restore the finish, use a polish. Finally, use a sealer to protect the surface.

Step 1: Clean the Area
Remove any debris from the crack in the solid surface countertop. Use acetone or rubbing alcohol to clean the area. Let it dry.

Step 2: Fix the Crack
There are two ways to fix a crack in a solid surface countertop: super glue or an epoxy filler. If you're using super glue, apply the glue to the crack and let it dry. The other method that can be used for cracks is an epoxy stick. You'll want to use one that matches the color of the countertop. Use the epoxy stick to fill in the crack and let it dry completely.

Step 3: Sand and Buff
Sand it with a fine-grit sandpaper, so that the surface is even with the rest of the countertop. Buff the area.

Step 1: Clean the Area
Use acetone or a cleaner that can be used on laminate. Let it dry.

Step 2: Fix the Crack
There are two ways to fix a crack in a laminate countertop: a paste or a putty. Ensure that the paste or putty is in the same color as your countertop, so that it will seamlessly blend in. Apply the paste or putty and smooth it out with a plastic scraper. Wipe off the excess and let it dry completely.

Step 3: Sand the Surface
Sand it gently with a fine-grit sandpaper, so that the repair blends in with the rest of the countertop.

To help prevent cracks in the future, follow these basic maintenance guidelines:

• Don't sit or stand on the countertops. Avoid placing heavy items on your countertop.
• Don't chop food directly on the countertop. Always use a cutting board.
• Cracks can occur from excessive heat. Use trivets for hot plates and dishes.
• It's important to seal natural stone countertops every six to twelve months. Excessive moisture can cause structural issues. A good sealant also prevents stains from setting and protects the surface from everyday wear and tear.

Sealing cracked countertops is important for maintaining the value of your home and restoring the countertop's aesthetic and usability. When it comes to countertop repair, quick action can prevent further damage. Depending on the type of filler used on the countertop’s surfaces, you can typically undertake simple repairs yourself. Larger cracks should be left to the professionals.
