How to Cut a Solid Surface Countertop By Jeremy Holloman
Step 1 Spread plastic on the driveway or flat surface where you plan to cut the countertop.
Step 2 Place the countertop on a pair of sawhorses on top of the plastic. Be sure to have someone else help you move the countertop.
Step 3 Mark the line of the cut on the countertop using a straight edge and a pencil.
Step 4 Clamp the straight edge to the countertop to guide the saw during cutting. If the edge that you are cutting will abut a wall and be covered by a backsplash, then you don't have to use the guide, as any imperfections in the cut will be covered.
Step 5 Cut the countertop using a circular saw and a new carbide-tipped blade, preferably one with 40 teeth to provide the smoothest cut possible. Move the saw slowly to prevent excessive heat buildup on the blade. Have a helper hold the nozzle of a Shop-Vac slightly behind the circular saw to capture most of the dust from the cut.
Step 6 Mark the next cut, if needed, and repeat the process.
**Don't use a cheap blade. Quality saw blades cost more but cut much better than the cheaper alternatives.
**Wear safety glasses and a respirator, because cutting a solid-surface countertop creates a lot of fine dust particles.
