how to cut solid surface countertops

Use a tape measure to note the exact dimensions of your countertop space (account for overhangs, backsplashes, or cutouts for sinks/appliances).

Transfer measurements to the solid surface sheet using a pencil or a grease pencil (visible but easy to wipe off later). For straight lines, use a straightedge (aluminum or steel works best—avoid flexible rulers) and clamp it to the sheet to keep your mark steady.

For curved cuts (e.g., around a sink), trace a template made from cardboard or plywood onto the surface. This helps you visualize the shape and adjust before cutting.

Lay a waterproof drop cloth or plywood sheet on the floor or workbench to prevent scratches on the solid surface’s finish.

If cutting indoors, open windows or set up a fan to reduce dust (solid surface cutting produces fine particles). For better dust control, use a shop vacuum with a HEPA filter—attach it to your saw if possible.

Cover the area around the cut line with masking tape (low-tack, to avoid residue). This minimizes chipping along the edges, especially for glossy or light-colored solid surface.

Circular Saw: For straight cuts (the most common type for countertops). Use a carbide-tipped circular saw blade with 100+ teeth (the more teeth, the finer the cut). Avoid blades with fewer than 80 teeth—they can tear the material or cause melting.

Jigsaw: For curved cuts or small cutouts (e.g., for a faucet). Choose a bi-metal jigsaw blade (designed for plastic/acrylic) with 10–14 teeth per inch (TPI) to prevent splintering.

Router: Optional but recommended for smoothing edges after cutting. Use a flush-trim bit or round-over bit (carbide-tipped) to refine rough edges and match the countertop’s original finish.

Clamps: Use 2–4 bar clamps or C-clamps to secure the solid surface sheet to the workbench. This prevents movement during cutting, which can lead to uneven edges.

Safety Glasses: Protect your eyes from flying dust and small debris.

Dust Mask or Respirator: Solid surface dust is fine and can irritate lungs—use a N95 or higher respirator for prolonged cutting.

Work Gloves: Prevent cuts from sharp edges and reduce hand fatigue.

Hearing Protection: Circular saws and jigsaws are loud—earplugs or earmuffs will shield your hearing.

Sand the Cut Edge: Use a sanding block (not your hand—this ensures even pressure) with 120-grit sandpaper to smooth any rough spots. Move the block in circular motions, then switch to 220-grit sandpaper for a polished look. For curved edges, use a flexible sanding sponge.

Router the Edge (Optional): If you want a rounded or beveled edge, use a router with a carbide bit. Secure the countertop to the bench, turn on the router, and move it along the edge at a steady pace. Start with a light pass, then gradually deepen the cut until you reach the desired shape.

Clean Up: Wipe the countertop with a damp cloth to remove dust. Vacuum the workspace to clear leftover debris—avoid sweeping, as this spreads dust into the air.

Avoid Overheating: Solid surface melts if the blade gets too hot. Keep the saw moving at a steady pace—if you notice smoke or a burning smell, stop and let the blade cool down.

Don’t Re-Cut Edges: If a cut is uneven, sand it smooth instead of re-cutting. Re-cutting increases the risk of chipping or making the countertop too short.

Wear All Safety Gear: Even a small piece of debris can cause eye damage, and dust inhalation is harmful over time—never skip safety glasses or a respirator.

Chipped Edges: If the top surface chips, sand the area with 220-grit sandpaper. For deeper chips, use a solid surface repair kit (mix acrylic resin and pigment to match the countertop color, fill the chip, and sand smooth).

Uneven Cuts: This usually happens if the saw wasn’t held steady or the sheet wasn’t clamped properly. Sand the uneven area with a sanding block until it’s level.

Melting Blade: Slow down the saw’s speed (most circular saws have adjustable speeds—use a lower setting for solid surface) or switch to a sharper blade.
