Corian is a solid surface countertop material made by Dupont. It is durable, heat-resistant and comes in a variety of colors and patterns. Corian can be cut with a circular saw, but it produces a lot of dust. For a cleaner cut, use a router with a special Corian bit.

Cutting the Countertop

You will need to cut the countertop to size before you can install it. You will need a straight edge and a sharp knife to cut the countertop. It is best to cut the countertop on a level surface. You will need to measure the countertop and mark it with a pencil before you cut it.

Measuring and Marking the Countertop

It’s important to take accurate measurements of your countertop space and plan your cutouts accordingly. Use a tape measure to determine the dimensions of your sink or cooktop cutout, and use a pencil to mark the area on the countertop. For an extra-precise measurement, trace the outline of your sink or cooktop onto paper, then cut out the paper template and use it to mark the cutout on the countertop.

Cutting the Countertop

Corian is a solid surface countertop material made by DuPont. It is non-porous, stain-resistant and easy to clean. Corian comes in many colors and can be cut and shaped to fit your kitchen countertop. You can cut Corian with a router or a jigsaw, but you need to use the proper blades and take care not to damage the surface.

To cut Corian with a router, you will need a straight router bit and a template guide. Set the router bit depth to half the thickness of the countertop. Place the template guide on the countertop and rout around the perimeter of the template. Remove the template and rout along the inside edge of the cutline to smooth any rough edges.

To cut Corian with a jigsaw, use a fine-toothed blade designed for cutting laminate or solid surface materials. Draw your cutline on the countertop with a pencil or marking pen. Drill a hole at each end of the cutline, then insert the blade of the jigsaw into one of the holes. Cut along the line, steering clear of any curves or corners. Use sandpaper to smooth any rough edges.

Finishing the Edges

When you are looking at how to cut Corian countertop, you will want to make sure that you understand the process. This is not a difficult task, but it is one that you need to be careful with. You will need to use a saw that is designed for cutting Corian and you will need to use a straight edge.

Filing the Countertop

After the holes for the faucet and sink have been cut out, it’s time to file the countertop. Use a fine-toothed file to remove any sharp or uneven edges from the cutouts. For the rest of the countertop, use a fine-grit sandpaper to smooth out any rough spots.

Sanding the Countertop

After the cuts have been made and the countertop has been installed, you will need to sand the edges to create a smooth finish. The best way to do this is to use a power sander with medium-grit sandpaper. If you do not have a power sander, you can use a block sander or sand by hand, but it will take longer and the results may not be as smooth.

Once the edges have been sanded, you will need to apply a Corian edge banding strip to any exposed edges. Edge banding strips are available in most hardware stores and come in both solid and veneered varieties. Veneered edge banding strips are thinner and easier to apply, but they will not provide as much protection as solid strips.

Applying the edge banding strips is a simple process, but it is important to follow the instructions carefully so that the strips adhere properly. First, clean the surface of the countertop with a mild solvent such as denatured alcohol. Next, apply a bead of adhesive to the back of the edge banding strip. Carefully align the strip with the edge of the countertop and press it into place. Use a putty knife or similar tool to smooth out any bubbles or wrinkles.

Let the adhesive dry for at least 24 hours before using the countertop. Once the adhesive has dried, you can sand the edges of the countertop again if necessary.


We hope this guide has been helpful in teaching you how to cut Corian countertop for your kitchen. With a little practice, you should be able to get perfect cuts every time. Be sure to use the proper safety equipment when working with power tools and always follow the manufacturer’s instructions.
