Shims and Other Leveling DevicesWhen assembling the countertop sections on the base cabinetry, you may discover that one piece sits slightly higher than the other, resulting in an unlevel surface. To ensure that adjacent slabs are flush and level, youll need to use wood or plastic shims to adjust for these minor height differences. Shims also hold the slabs in place until the adhesive used to mount the countertops to the cabinets sets. When installing an undermount sink, youll also need some tools to ensure a snug fit with the concrete countertop. Buying tips: Lloyd recommends using special lifting clamps that you can stick in the sinks drain hole to pull the sink up tightly (available at Granite City Tool). Proper shimming of the sink is also important. Lloyd uses a mounting system called Sink Undermounter, manufactured by Vance Industries. It consists of metal rails with 2-inch adjusting bolts that can be turned as necessary to raise and level the sink flush with the underside of the countertop. Be sure to seal between the countertop and sink with a clear acrylic kitchen and bath caulk, adds Girard.
