Undermount Bathroom Sink – Installing a mounting sink on a granite countertop requires precision, accuracy and proper mounting techniques. That is to prevent it from separating from the bottom of the countertop and falling into the cabinet below. In addition to the mounting elements that come with a retail undermount sink kit. The epoxy sealer is needed to solidly attach the sink to the granite. Properly installed, an undermount sink attaches to the underside of the deck, allowing the countertop surface to serve as sink lip and rationalizing the countertop surface. To install this right sink, assign an assistant to hold the sink while you attach the clips to it.
Measure the width of the hole and cut a length of 2 inches by 4 inches of slightly longer wood using a hand-held sink. Wipe the underside of the granite surface with a dry cloth to remove accumulated dirt. Apply a uniform layer of silicone sealant around the top edge or edge of the undermount sink. Pick up under the sink cover and lift with your caulked lip centered in the opening in the granite counter. Push the sink against the bottom of the countertop.
Place the 2-inch-by-4 inches of wood over the sink cutout on the top of the countertop, directly through the sink opening. Tighten the clamp partially so it holds the sink assembly in place. Prepare the two-part epoxy according to the instructions on its label. Tighten the screws that hold the clamps in place and allow the epoxy and putty to cure for the time specified in the label instructions.
