Fitting Undermount Sink To Granite

Installing an undermount sink to granite countertops can be a challenging project, but it is possible to achieve a professional-looking finish with careful planning and execution. Here is a guide to help you through the process.

Materials and Tools

* Undermount sink * Granite countertops * Sink template * Measuring tape * Level * Pencil * Jigsaw or circular saw * Router * Sandpaper * Caulking gun * Silicone caulk * Utility knife

Step 1: Measure and Mark the Cutout

* Place the sink template on the granite and trace around it with a pencil. * Use a measuring tape to ensure that the template is centered and evenly spaced from the edges of the countertop. * Check the level to ensure that the template is level.

Step 2: Cut the Granite

* Use a jigsaw or circular saw to cut out the hole for the sink. * Cut along the inside of the pencil line to create a slightly smaller hole than the template. This will allow for a small gap for the caulk. * Smooth the edges of the hole with sandpaper.

Step 3: Create a Scribe Line

* Place the sink in the hole and trace around the outside edge with a pencil. * This line will be used as a guide for cutting the granite to create a flush fit.

Step 4: Cut the Granite Scribe Line

* Use a router to cut a groove along the scribe line. * The groove should be about 1/8 inch deep and wide enough to accommodate the edge of the sink. * Sand the edges of the groove to smooth them out.

Step 5: Install the Sink

* Spread a bead of silicone caulk around the edge of the sink. * Carefully lift the sink into the hole and press it into place. * Use a level to ensure that the sink is level. * Secure the sink with clamps or weights.

Step 6: Caulk the Sink

* Allow the caulk to dry for several hours. * Use a utility knife to trim any excess caulk. * Apply a second bead of caulk around the outside edge of the sink where it meets the granite. * Smooth the caulk with your finger or a caulk tool.

Step 7: Clean the Counters

* Wipe the countertops with a damp cloth to remove any caulk residue. * Use a glass cleaner to clean the glass surface of the sink.

Tips

* Wear safety glasses and gloves when cutting the granite. * Test the fit of the sink in the hole before applying caulk. * Use a sharp blade when cutting the caulk. * Allow the caulk to dry completely before using the sink.
