## How to Seal Kitchen Sink Strainer
A kitchen sink strainer is a small device that fits over the drain hole in your sink. It helps to prevent food and other debris from clogging the drain. Over time, the strainer can become loose or damaged, which can allow water to leak out around the edges. This can lead to water damage to your cabinets and floor.
There are a few different ways to seal a kitchen sink strainer. The most common method is to use plumbers putty. Plumbers putty is a soft, pliable material that can be molded around the strainer to create a watertight seal.
**Materials you will need:**
* Plumbers putty
* Putty knife
* Rag
* Bucket
**Instructions:**
1. Clean the area around the strainer. Remove any old plumbers putty or debris.
2. Roll out a small piece of plumbers putty into a snake-like shape.
3. Place the putty around the base of the strainer.
4. Use your finger or a putty knife to smooth the putty out.
5. Wipe away any excess putty with a rag.
6. Fill the sink with water and check for leaks. If you see any leaks, add more putty until the leak is stopped.
**Tips:**
* If you don’t have plumbers putty, you can use silicone caulk instead.
* If the strainer is loose, you may need to tighten the screws that hold it in place.
* If the strainer is damaged, you may need to replace it.
## How to Seal Kitchen Sink Strainer with Silicone Caulk
Silicone caulk is a type of sealant that is often used in plumbing applications. It is a flexible material that can create a watertight seal around the strainer.
**Materials you will need:**
* Silicone caulk
* Caulk gun
* Rag
**Instructions:**
1. Clean the area around the strainer. Remove any old caulk or debris.
2. Apply a bead of caulk around the base of the strainer.
3. Use your finger or a rag to smooth out the caulk.
4. Wipe away any excess caulk with a rag.
5. Allow the caulk to dry for 24 hours before using the sink.
**Tips:**
* If you don’t have a caulk gun, you can use a small spoon or your finger to apply the caulk.
* If the caulk is too thick, you can add a little bit of water to thin it out.
* If the caulk is too thin, you can add a little bit of cornstarch to thicken it up.
