If you just bought a countertop from Ikea and didn't have it cut to length, you can do it yourself at home with the right tools. Ikea sells two types of countertop -- laminate and butcher block, which are both cut to length the same way. Unlike many traditional laminate countertops, Ikea countertops do not have a backsplash, so you don't need a jig to cut them. For best results, use clamps to help hold the countertop in place during the cutting.
Turn the Ikea countertop over so the countertop is face down.
Measure the space where you're putting the countertop. Add 1/16 inch to the measurement. This is how long you need to cut the countertop.
Measure the countertop from the end to the length of the space. Use a level or a straightedge to draw a straight line across the countertop to mark it.
Place a strip of masking tape on the top of the counter where the blade will cut through to keep the laminate or wood from chipping.
Measure the depth of the countertop. Ikea countertops are typically 1 1/2 to 1 3/8 inches thick.
Cut the countertop to length using a circular saw. Use a thin-kerf carbide circular saw blade that will reach a depth of 1/8-inch more than the countertop thickness
Clean up any rough edges with a jigsaw, if needed.
Use a belt sander to sand the edge of the countertop smooth.
To cut out a hole for the sink, place the sink template where the sink should go. Trace the template and cut along the line with the jigsaw.
Always wear protective gear, such as safety glasses, when using power tools.
