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.

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.
