How to Fix a Crack in Corian Countertops

Gather Your Supplies and Equipment

You need to make sure you have everything before you start. Stopping in the middle of the repair to get something may ruin the repair. You will need an epoxy seam sealer, cotton swabs, hairdryer, a bag of ice, hydrogen peroxide, paper towels, orbital sander, 220, 320 & 400-grit pieces of sandpaper, paper plate, craft stick.

Step-By-Step Process

Step 1 – Get the bag of ice from your freezer and place it over the crack. Let it sit there for 45 minutes cover the area up to 6 inches on either side. This will slightly widen the crack.

Step 2 – Mix liquid dishwashing soap with warm water and thoroughly clean the crack. Use the paper towels to dry the washed area.

Step 3 – Use a cotton swab or a Q-tip to dab some hydrogen peroxide inside the crack. This will kill any bacteria that may be growing there. Then wipe dry with paper towels.

Step 4 – Start with the 220-grit sandpaper, attach it to the sander and begin to sand. Use low speed and be delicate around the edges of the crack. When the edges are smooth and no material is raised stop sanding and remove the dust using a damp cloth or paper towels. Then dry the crack.

Step 5 – Now use your hairdryer to apply heat to the crack and the 6-inch surfaces on each side of the crack. This will help it contract slightly and do this for 20 minutes.

Step 6 – Take your paper plate and put it in position. You want to put the epoxy seam sealer on the plate and use the craft stick to mix them. You have to be careful and a little quick as the epoxy sealer starts to dry the moment the two ingredients are mixed together.

Step 7 – When the mixture is ready, use the craft stick to fill the crack. Keep going until the crack is completely filled. Then carefully wipe the sides of the craft stick along the edge of the crack to smooth out the sealer and remove the excess from the stick.

Step 8 – Wait for the epoxy sealer to dry. You can see how long it takes to dry by reading the label. Once dry, place the 320-grit sandpaper on the orbital sander and start to sand once again. Be gentle with the pressure as you only want the epoxy to be flush with the countertop.

Step 9 – When you are finished smoothing out the epoxy with the 320-grit sandpaper, replace it with the 400-grit piece. All you need to do to get a mirror-like finish is to run the orbiter sander over the filled crack a couple of times.

Step 10 – After everything is said and done, pack up your tools and supplies. Then clean the area around the crack and the repaired crack as well. Make sure it is sterilized and clean before you do any food prep.

Small chips and scratches can normally be sanded out when they appear on your Corian countertop. But as you can see, the cracks that can come take a little more effort to get rid of.
