Can a Corian-Like Countertop With a Molded Sink Be Covered?

Corian Advantages

• Corian countertops with built-in sinks are preferred by many builders due to the variety of shapes possible with the synthetic stone material. Countertop manufacturers create molds that include both the sink and the counter so they can both be made at once and fitted at the same time, saving on price and installation. Both the sink and the countertop are made from the same material simultaneously, so coatings can be used on both types.

Finishes

• Finishes are clear coatings used to protect Corian and other similar countertops. They act like sealants to keep moisture from damaging the surface over time and preserving the surface color. The finish will bond with the synthetic stone and protect it. There are three types of finishes available: matte, semi-gloss and high-gloss. The most common finish is matte, but you can use a gloss to change the counter's appearance.

Other Coverings

• Covering synthetic stone with additional materials can be risky, but some epoxies or similar resins may be able to bond properly to the counter surface. Always check the labels and manufacturer's instructions to see if the resin will work on synthetic stone. In many cases manufacturers will indicate if the resin or sealant can be used on Corian specifically. This makes it easier to completely change the color of your countertop without replacing it entirely.

Notes on Finishes

• Since you have a molded sink, you will need to carefully trace out the sink and apply resins around the sink instead of coating the sink itself, which can require detailed work. Also note that finishes, sealants and resins are not designed to bond with other sealants or caulks. You will need to thoroughly clean away all caulks and re-apply them when using a new sealant or covering.
