Step-by-Step Guide: How to Install an Undermount Sink on Granite Learning how to install an undermount sink on granite requires patience and precision. Granite is a heavy, durable stone, and proper installation ensures both beauty and long-term function. Whether you’re working with granite countertops near Lowell, handling a fresh granite fabrication, or even doing a granite repair, these steps will guide you toward a successful undermount sink installation. Step 1: Measure and Cut the Opening Precision is key when working with granite. Use a sink template to outline your cutout on your countertop, so your sink fits seamlessly without gaps or misalignment. Step 2: Dry Fit the Sink Before applying adhesives, place the sink into its cutout to check its alignment with the cabinet below and ensure it sits evenly and in line. If faucet holes are required, mark them now to avoid mistakes later. Step 3: Apply Adhesive and Sealant Utilize an epoxy adhesive with silicone sealant and apply carefully around the cutout edges, providing both bonding strength and watertight sealing against moisture seepage. This step ensures proper adhesion of granite countertops over time. Step 4: Secure the Sink with Clips and Supports Attach undermount sink clips and support brackets to keep the sink securely in place while its adhesive sets, to prevent sagging – an especially crucial factor when installing heavy sinks under stone countertops. Step 5: Allow Adhesive to Cure Allow the adhesive to set according to its manufacturer’s recommended drying time. Delay connecting any plumbing until its bonds have completely set before proceeding with drain and faucet installations. After your sink has set properly, check its alignment and ensure it feels secure before moving forward with drain/faucet installations.
