Prevent Heat Damage

Although Corian is an excellent material for heat resistance, it is still very important to minimize direct heat exposure to protect your Corian surface and investment.  

We recommend using heat trivets or hot pads with placing hot objects on your Corian countertop.  It is also recommended to allow cookware to cool before placing them in your Corian sink.

Although boiling water alone will not damage your Corian sink, we still recommend running your faucet while pouring boiling water into your sink

Preventing Other Damage

Help maintain the beauty of your countertops by:

  • Avoiding direct exposure to strong chemicals, such as paint removers, oven cleaners, etc. - if contact does occur, quickly flush the surface with water
  • Do not cut directly on your Corian countertops  

We'll provide you with a color matched Corian cutting board if you buy your countertops from us so you'll have something to cut on
