How to Fix a Crack in a Corian Countertop

Cracks ruin the finish of your Corian countertop. A crack can also allow water and other liquids an entry point in which to weather away at the interior of the counter and damage the plywood and cabinetry underneath. Cracks can be repaired with a joint sealant that is compatible for Corian countertops. These sealants come in a variety of colors; select the color that most closely resembles your countertop.
