Apply Plumber’s Putty

Applying plumber’s putty is an important step in installing a new sink strainer. Plumber’s putty helps create a watertight seal between the sink and the strainer, preventing any water leakage. Follow these steps to apply plumber’s putty:

Start by preparing the plumber’s putty. Take a small amount of putty and roll it between your hands to soften it.
Once the putty is pliable, form a rope-like shape by rolling it into a thin and even strand. The length of the putty should be slightly longer than the circumference of the sink drain opening.
Place the putty strand around the underside of the new sink strainer. Ensure that the entire circumference of the strainer is covered by the putty.
Gently press the sink strainer with the plumber’s putty onto the sink drain opening. Apply even pressure to create a secure seal between the sink and the strainer.
Remove any excess putty that squeezes out from the edges using a clean cloth or your finger. The putty should form a smooth, continuous ring between the sink and the strainer.

It’s important to note that plumber’s putty should not be used with certain sink materials such as granite, marble, or other porous surfaces. In such cases, it’s recommended to use silicone caulk instead as it is safe for these materials.

Once you have applied the plumber’s putty and attached the sink strainer, you’re ready to move on to the next step: installing the new sink strainer.

Install the New Sink Strainer

Now that you’ve prepared the sink drain and applied plumber’s putty, it’s time to install the new sink strainer. Follow these steps for a proper and secure installation:
