How to Repair Cracks in Solid-Surface Countertops


Solid-surface countertops are made from molded epoxy resin. They are designed to repel moisture and chemicals. Solid-surface countertops will last a lifetime with the proper care. Installing a solid-surface countertop places it at risk for a crack if it is not handled with the utmost care. A crack in the surface will give food and germs a place to hide, creating a hazardous condition in your kitchen. To repair your cracked solid-surface countertop, you'll have to fill the damaged area with epoxy to bind the two halves of the counter back together.

Things You'll Need

  • Soft, clean rags
  • Bucket of wet, soapy water
  • Two-part epoxy
  • 1-inch plastic putty knife
  • Enamel paint (assorted colors)
  • Artist's paintbrush
  • Spray polyurethane
  • Rubber gloves
  • Safety glasses
  • Dust mask
  • Dip a clean, soft rag into a bucket of warm, soapy water. Wring out the rag and clean the crack inside and out. Dry the area with a clean rag.

  • Read the directions on the two-part epoxy. Mix the epoxy base and its hardener as directed by the manufacturer.

  • Dip the tip of the blade of a plastic 1-inch putty knife into the epoxy mixture and scoop out a 1/4-inch piece. Press the epoxy into the crack and repeat until the crack is filled.

  • Scrape the blade of the putty knife along the length of the crack to remove any excess epoxy. Let the epoxy cure overnight.

  • Dab enamel paint onto the hardened epoxy, using an artist's brush. Apply one color at a time, and let it dry completely before applying the next color. Add the colors you need to camouflage the repair so that it matches the rest of the countertop.

  • Spray polyurethane onto the painted patch to seal it and complete the repair. Let the polyurethane dry completely before using your countertop.

Tips & Warnings

  • Solid-surface countertops are generally heat-resistant. However, sudden heat application from appliances such as hot plates or coffee pots should be avoided. Always use a cutting board under heated appliances to protect your solid-surface countertop.
  • Rubber gloves, safety glasses and a dust mask are required when working with chemicals such as epoxy, paint and polyurethane.
