Whether you’re installing a new countertop or giving your old one a facelift, you’ll need to know how to cut Corian countertops. Corian is a solid surface countertop material made by DuPont. It’s made of acrylic and alumina trihydrate, which gives it a nonporous, heat-resistant andrepairable surface. Corian comes in more than 100 colors and patterns and can be cut, shaped, drilled and routed like wood.

Here are the steps you’ll need to follow to cut Corian countertops:

1. Mark the cutting line on the back of the Corian sheet with a pencil. Use a straightedge to help make your line as accurate as possible.
2. Place the Corian sheet on a stable work surface, such as a sawhorse or table saw stand. Make sure the cutting line is facing up.
3. Score the cutting line with a utility knife fitted with a sharp blade. Apply steady pressure as you move the blade along the length of the line. The goal is to score just deep enough so that you can snap the sheet along the scored line later on.
4 Place one hand on each side of the scored line and gently flex the sheet until it snaps along the line. If necessary, use clamps to hold onto both sides of the sheet while you’re snapping it.
5 Finish cutting through any remaining material with a jigsaw fitted with an abrasive metal-cutting blade designed for use with nonferrous metals like aluminum or copper (do not use a standard wood-cutting blade). Clamp the jigsaw in place so that its baseplate is flush against one side of your cutline start the saw and guide it along the cutline, keeping firm pressure on both handles as you move forward


Because Corian is flexible, it’s best to use a straightedge and a utility knife to score it deeply. After you’ve scored the front and back of the Corian sheet, place it on a stable work surface. Using a saw with a fine-toothed blade, cut along the scored line. Next, use sandpaper to smooth any rough edges on your newly cut Corian countertop.
