DIY Guide: Repair a Cracked Corian Counter Top

When your Corian countertop cracks, it can be a little devastating. Thankfully, you can repair it yourself so that the Corian countertop is still in one piece and will be functional for years to come.

1. Put away the superglue and resin, and stop looking at DIY sites for your answer. Those items won’t fix the crack, which can travel over time. Often times someone posts a “miracle solution” to fixing your Corian counter top, but it won’t work. While you’re at it, come to the realization that your countertop won’t look the same after a home repair as when you first had it installed. This is the cost of doing it yourself.

2. Know your material. Corian is a product from DuPont developed in the 1960s that is made of acrylic polymer and alumina trihydrate. These materials create a strong, durable countertop that is easy to care for unless you break it.

3. Gather your supplies to repair your Corian countertop. To fix your countertop, you will need a screwdriver, piece of plywood, strong glue like Gorilla Glue, clamps, wood scraps, superglue, and a Scotch Brite pad.

3. Remove the portion of countertop by unscrewing it from the base. If your Corian countertop does not come off after you unscrew it, contact the installation company or hire one to fix the countertop. The only way to fix a Corian piece is to remove it, so if you can’t do that, you should have it fixed professionally to avoid further damage.

4. Cut a piece of plywood to fit most of the bottom of the removed piece of counter top. Make sure the plywood goes over the section that is cracked. Use a strong glue, such as Gorilla Glue, and dot it over one side of the plywood. Put the board onto the back of your counter top immediately, holding both sides down with clamps so that the wood is flush with your countertop. Let it dry.

5. Then glue a few small pieces of wood to the ends of the attached plywood to strengthen the structure before screwing the countertop back in.

6. Apply superglue to the crack. Let it sink into the crack for a moment, and then rub the excess glue away with a Scotch Brite pad. If you want to maintain the look of your countertop, rub the entire Corian section to make the crack blend in even better.

7. Know when to give up. If your Corian counter top doesn’t look so good after a DIY repair, you need to hire a counter top repair specialist so that it doesn’t crack further.
