How To Caulk Under Bathroom Sink

How to Caulk Under a Bathroom Sink

It frequently happens that the area under the bathroom sink has caulking. Keeping water inside the sink and away from the cabinet and floor is the purpose of this caulking. Keeping regular caulking prevents mold and mildew from growing and causing damage. You can caulk under a bathroom sink in a few simple steps if you know how.

Things You'll Need

Caulk gun
Caulk
Putty knife
Paper towels
Safety glasses
Gloves

Step 1: Preparation

Put on gloves and safety glasses. Remove the old caulk from the joint between the sink and the countertop with a putty knife. To remove the old caulk, scrape it away carefully. To get rid of any leftover caulk or residue, wipe the area with a paper towel.

Step 2: Apply Painter’s Tape

Apply painter’s tape to the edges of the joint between the sink and the countertop. The tape will prevent the caulk from getting on the sink or countertop. Make sure the tape is pressed down firmly so that no caulk can leak underneath it.

Step 3: Apply the Caulk

Cut the tip of the caulk tube at a 45-degree angle. Place the caulk tube in the caulk gun and trigger the gun to release a small amount of caulk.

Apply a thin, even bead of caulk to the joint between the sink and the countertop. Work slowly and carefully, making sure to fill the entire joint. Don't apply too much caulk, as this can make it difficult to clean up.

Step 4: Remove the Painter's Tape

Remove the painter’s tape while the caulk is still wet. Be careful not to smudge the caulk. If you do smudge the caulk, use a wet paper towel to clean it up.

Step 5: Let the Caulk Dry

Allow the caulk to dry according to the manufacturer's instructions. This usually takes 24 to 48 hours. Once the caulk is dry, it will be hard and waterproof.

Additional Tips

If you are caulking a joint between two different materials, such as a ceramic sink and a laminate countertop, use a caulk that is specifically designed for that type of application.
If you are caulking a joint that is exposed to a lot of water, such as the joint between a shower and a bathtub, use a waterproof caulk.
To make the caulk job last longer, apply a fresh bead of caulk every year or two.

Conclusion

Caulking under a bathroom sink is a simple project that can prevent water damage and keep your bathroom looking its best. Simply follow the steps above, and you'll have a professional-looking caulk job that will last for years.
