Kitchen Faucet Base Sealing: 3 Easy Steps

It is important to know whether you have selected a high-quality faucet. However, you must also take care to ensure that it is properly fitted. If the faucet is not properly placed, there will be leaking and your kitchen will become chaotic. 

No worries! We are here to help you find a solution to this situation. All you need to do is follow the instructions properly. Let’s get started!

Step 1: Select the Right Sealant 

To start the sealing process, first, turn off the water supply lines and remove the wax on the surface and make the base clean. Turn off the water at the faucet by reaching under the kitchen sink. 

Second, take the plates out of the sink and place a hand towel over the drain. You don’t want anything to go to waste, so keep everything in a safe place.

Finally, take the wrenches and rubber gloves tools. Next, detach and remove the base with the water supply lines turned off so there could be no possibility of some other squirt in the face.

And to choose the right kitchen faucet sealant, you can consider these two: silicone caulk and

plumber’s putty. Teflon tape could be useful in some situations as well, but it isn’t applicable here because there isn’t a pipe thread that has to be addressed.

Now, you could get a little confused about which one to choose between these three options. To help you out, here we can have a little discussion on the sealants.

 Each of these alternatives is simple to use and can effectively plug a faucet leak. The decision on which to utilize in your situation will be influenced in part by the magnitude of the project.

Silicone caulk will harden, but the plumber’s putty will always be soft. The former will require time to harden, whilst the latter does not require time to cure.

The plumber’s putty is not really glued. It’s a soft and malleable sealing material that plumbers and do-it-yourselfers use to create a waterproof seal around faucets, sink drains, basins just at countertop joints, and also other plumbing fittings.

The putty is inherently water-resistant and works best when a sealer is only needed in small spaces. The process is super easy unlike extending the faucet supply lines.

You can purchase your desired sealants from these recommended products below.

Step 2: Applying the Sealants

After deciding which sealant you want to go with, you have purchased the sealant from the market. Then you can follow the described way to apply it to your kitchen faucet. Each is simple to deal with and has a basic approach.

While applying the plumber’s putty, take a table tennis ball-sized piece of putty, roll it in between your two hands, then shape it into a round size of the leaking faucet base.

The base would then be inserted into the putty. It will make a good seal throughout and resecured. Remove any extra putty using your fingers, check sure the border of the base plate is tidy, and you’re done.

Larger tasks that will need a large amount of sealant will benefit from the use of a silicone caulk which will be dried. To finish it perfectly, it is recommended to remove the screw set of the faucet as well and then reinstall it.

Step 3: Drying

You’ve completed applying the appropriate sealant for the leak problem, as well as the kitchen faucet base has been reinstalled and fastened. There are only a few more steps to take:

In case you applied the plumber’s putty, you may reconnect the water supply because it does not need to dry. This time, it’s loosey-goosey.

Before turning on the water, observe the drying time recommendations on the package if you used silicone caulk.

Lastly, remove the towel that was covering the drain. And you are done when the water is finally turned on, you can use it again. 

Congratulations! You are done with the sealing process. Hopefully, this method will help you to get out of the leaking problem.

Answer: Replace the faucet base into the hole or holes in the sink or countertop. Return the nuts and gaskets to their original positions on each piece of the faucet.
