To seal a kitchen sink, clean the sink and the surrounding countertop area thoroughly. Apply a bead of silicone caulk around the edge of the sink where it meets the countertop. Smooth the caulk with a caulking tool or your finger for a neat finish. Allow the caulk to cure for the recommended time before using the sink. This prevents leaks and water damage around the sink area.

Sealing a kitchen sink involves applying silicone caulk to prevent leaks and water damage. Benefits include a more watertight seal and reduced risk of damage. Challenges include ensuring a smooth and complete application. Proper sealing helps maintain the integrity of the sink and surrounding area.
