Easy Way to Cut RV Corian Countertops

RV Corian countertops are a popular choice among recreational vehicle (RV) owners due to their durability, elegance, and ease of maintenance. However, there may come a time when you need to modify or replace a section of your RV Corian countertop. Cutting RV Corian countertops requires precision and care to ensure a clean and accurate cut. In this article, we will guide you through the step-by-step process of cutting RV Corian countertops, equipping you with the knowledge and techniques necessary to successfully complete this task.


Tools Required

Before you begin cutting your RV Corian countertop, it is essential to gather the necessary tools. Here’s a list of tools you’ll need for this project:

  • Safety gear:Safety glasses, dust mask, and work gloves to protect yourself during the cutting process.
  • Measuring tools:A tape measure and a straightedge ruler to ensure accurate measurements and straight cuts.
  • Marker: A pencil or marker to mark the cutting lines on the Corian surface.
  • Clamps: Heavy-duty clamps to secure the Corian countertop in place during cutting.
  • Jigsaw or circular saw: A jigsaw or circular saw with a fine-toothed, carbide-tipped bladeto cut through the Corian material.
  • Diamond saw blade:A diamond saw blade specifically designed for cutting hard materials like Corian. The recommended size is typically a 10-inch blade with a continuous rim for a smooth and clean cut. The type of diamond saw blade you should use is a laser welded diamond blade. These blades offer excellent durability and precision when cutting through hard materials like Corian.
  • Sandpaper:Various grits of sandpaper (from coarse to fine) for smoothing and finishing the edges of the cut Corian.


Step-by-Step Guide

After gathering the necessary tools, follow these steps to cut your RV Corian countertop:

  1. Measure and mark: Use a tape measure to determine the precise dimensions for the cut you need to make on the Corian countertop. Mark the cutting lines clearly using a pencil or marker. Double-check your measurements to avoid any errors.
  2. Secure the countertop: Place the Corian countertop on a stable work surface. Use heavy-duty clamps to secure it firmly, preventing any movement during the cutting process. Ensure that the area you’re cutting is overhanging the edge of the work surface to prevent damage to the underlying surface.
  3. Put on safety gear: Prioritize safety by wearing safety glasses, a dust mask, and work gloves to protect yourself from debris and airborne particles during the cutting and sanding processes.
  4. Choose the right saw: Depending on your preference and the complexity of the cut, you can use either a jigsaw or a circular saw. Both tools work well for cutting Corian, but a jigsaw provides more maneuverability for curved cuts, while a circular saw is ideal for straight cuts.
  5. Install the diamond saw blade: If you’re using a circular saw, remove the standard blade and replace it with a 10-inch diamond saw blade specifically designed for cutting hard materials like Corian. Follow the diamond tools manufacturer‘s instructions for installing the blade securely.
  6. Start cutting: Position the saw blade just outside the marked cutting line to prevent chipping of the Corian. Move the saw steadily along the cutting line, applying gentle pressure. Let the saw blade do the work, and avoid forcing it through the material, as this can lead to uneven cuts or damage the Corian surface.
  7. Cutting techniques: For straight cuts, use a straightedge ruler as a guide, ensuring the saw blade stays aligned with the marked line. For curved cuts, guide the jigsaw along the marked line, maintaining a steady and controlled motion.

  1. Sand and finish the edges:After making the desired cuts, you’ll notice rough edges on the Corian countertop. To smooth and finish the edges, use progressively finer grits of sandpaper. Start with coarse-grit sandpaper to remove any burrs or unevenness, then gradually work your way to finer grits until the edges are smooth and polished.
  2. Clean up: Remove the clamps and clean up any debris or dust created during the cutting and sanding processes. Wipe down the countertop with a clean, damp cloth to remove any remaining dust particles.



Cutting RV Corian countertops requires careful planning, accurate measurements, and the use of the right tools. By following the step-by-step guide outlined in this article, using a 10-inch diamond saw blade designed for cutting hard materials like Corian, you’ll be able to achieve clean and precise cuts on your Corian countertop. Remember to prioritize safety by wearing appropriate protective gear and take your time to ensure accurate measurements and cuts. With proper technique and the right tools, you can successfully modify or replace your RV’s Corian countertops to suit your needs.
