Do It Yourself Corian Countertop Repair

Updated July 20, 2017

Corian is a synthetic material, made by DuPont, frequently used to create sinks and countertops in kitchens and bathrooms. It is a popular alternative to natural stone because it is non-porous and does not require sealing treatments. It is also stain and heat resistant and available in over 100 colours. Corian countertops are designed to be easily repaired.

Scratches

Most scratches occur from knives cutting into the corian, so always use a cutting board. To repair scratches, begin by sanding it with a fine grit sandpaper; depending on the severity of the scratch, you may need to use a heavier grit. Once you have sanded the scratch out, switch to a finer grit and blend the area with the rest of the countertop. Wipe the area with a moist cloth.

Blotchy Spots

If your corian has a blotchy appearance, use a light abrasive cleaner, such as Soft Scrub and a sponge. Rub the surface thoroughly with a circular motion. You may need to repeat the process, rubbing harder each time, until the blotchy patches are gone. This process can also be used to remove very fine scratches.

Burns and Stains

Because corian has a non-porous surface, stains are easy to remove and are not permanent. Corian is heat-resistant; however, placing hot pots directly on the surface can result in scorching. To remove stains or scorch marks, simply rub the surface in a circular motion with a grey Scotch-Brite pad and a mild cleaner. Wipe it with a damp cloth when the stain is gone. Don't use green Scotch-Brite pads; they are too abrasive for corian surfaces.

Daily Cleaning and Maintenance

Clean your corian surface with warm soapy or water or an ammonia-based cleaner. You may need to use a stronger cleaner for deeper stains. Always wipe the surface dry after cleaning; letting wet areas dry on their own will cause the surface to dull and lose its shine. If your corian has hard water marks, clean it with speciality cleaners, such as Lime-Away.
Corian is available in over 100 colours; darker colours are more vulnerable to show scratches and stains and will require more regular maintenance. Over time, your countertop will lose its shine and may need to be refurbished. Disinfect your corian surface regularly with a mild bleach and water mixture.
