Installing A Countertop Sink
Create a template. If the sink does not come with a template, create one bylaying the sink facedown on a sheet of cardboard and drawing a line around the edge. Lift off the sink and draw a second line 3/4 inch inside the first line. Cut along the inside line with scissors. Mark the center of the cabinet from below. Drill a hole large enough to fit a finishing nail.
Mark the center of the template. Push a nail through the center of the template into the hole. Center the template and square the edges so the rim will lie entirely on the surface. Trace the outline on the countertop. Remove the template and place tape along the edge. Replace the template and draw the outline of the sink on the tape. Remove the template.
Drill a 3/4 inch hole inside the cutout line. Use a power drill and spade bit to make a starter hole for the saber saw. Install braces beneath the countertop. The braces will support the section it from binding while cutting.
Cut out the opening. Use a saber saw with a blade design to cut countertops without chipping the surface. Remove the masking tape. Test-fit the sink and trace the rim lihtely on the countertop.
Apply a bead of silicone caulk inside the line. Apply a steady, continuous bead between the mark and the opening.
Place the sink in the opening. Press the sink firmly inthe the silicone caulking, then level and clean. Connect the faucets and the drains. Test for leakage. Clean away excess silicone. Trim silicone caulking with a plastic putty knife for that professional appearance.
