Things You'll Need
Cutting a 45-degree angle in a laminate countertop will allow you to create a corner in your kitchen counter. It's not any different than cutting a 90-degree angle on a laminate countertop. A bit of extra measuring and the right equipment will enable you to make the cut, adding aesthetic appeal to your kitchen.
Measure the top of the kitchen cabinetry with a measuring tape. Since the laminate countertops will be cut to create a corner, measure the back edge of the cabinets along the wall. This will give you the proper length for the longest portion of the countertop.
Transfer the measurement from the back of the kitchen cabinets to the bottom of the laminate countertops with a pencil. Flip the laminate countertop over so you see the bottom of the countertop. Measure and mark the bottom of the countertop next to the backsplash.
Place a carpenter's square along the line you created on the bottom of the countertop. The square will allow you to measure and mark a 45-degree angle on the bottom of the countertop. Use a pencil to mark the angle. You will be making the cut in the countertop along this line.
Make a 45-degree-angle cut in the laminate countertop with a circular saw. With the countertop upside down, begin cutting the countertop along the line you previously made. When you reach the backsplash on the countertop, angle the circular saw downward to cut the entire countertop. Always cut the laminate countertop with the sawblade going through the wood side of the laminate countertop. This will help prevent the laminate countertop from chipping as it is cut.
Repeat this process with a second countertop. When put together, the two countertops cut at a 45-degree angle will create a 90-degree angle corner.
