The kitchen sink gets a lot of wear and use out of it which can cause things to go wrong. If the kitchen sink isn't properly sealed it can become one of the worst messes you may have to clean up in your home. There is no need to hire a plumber to come out and fix the seal on a kitchen or to even install one from scratch. Save the money and do it yourself. The following article will walk you through the process of how to seal your kitchen sink.

Step 1 - The Water

The first thing that you need to do before actually getting to work is to be sure that the water is turned off. Under the kitchen sink you will find valves attached to pipes. Turn them to the right to shut them off. Make sure they are tight, but not too tight that you can't turn them when you're finished. When they are turned off you can turn the water on at the kitchen sink to make sure the water is actually turned off.

Step 2 - Preparing to Seal the Kitchen Sink

There will be water trapped in the pipes so place the bucket in the bottom of the kitchen sink under the pipes along with some towels. This will catch water from spilling all over the place and potentially causing water damage. You can now disconnect the hot and cold water from the faucet of the kitchen sink. Do not be alarmed as water will drain from these pipes. Remove the drain pipe from the kitchen sink as well. You can now lift the faucet out of the basin. You may need to remove caulk from under the sink or remove screws.

Step 3 - Removing the Kitchen Sink

Once all of the components are detached you can return to the surface to remove the kitchen sink from the counter. Use the utility knife and carefully cut around the edge of the kitchen sink. Be careful not to damage the counter. You are basically slicing through the silicone. When you are done you can grab the kitchen sink and pull straight up to remove it. Lay it upside down on a flat surface.

Step 4 - Sealing the Kitchen Sink

Before you can properly seal the kitchen sink you need to use the utility knife to scrape the old caulk off the sink as well as the counter. You can now use kitchen cleanser to thoroughly clean both surfaces. Apply the caulk to the underside of the kitchen sink around its edges in a thin bead. You do not need too much because it will spread when you replace the sink. Place the sink back in place and apply a bead of caulk along the edge where it meets the counter. Use a rag and wipe away any excess caulk. The caulk needs to set before you should use the sink. Replace the faucet, connect the drain and turn on the water.
