Whether you are caulking a newly installed bathtub or replacing existing caulking to prevent water damage or you're simply disenchanted by the cracks and discoloration that occur over time, this project guide will show you how to do it right the first time. Fortunately, replacing caulking is an easy, breezy home improvement project that you can do in just a matter of minutes.

 

Step by Step Instructions

Step 1

Remove old caulking. Use a putty knife or a flathead screwdriver to scrape away the old caulking.

 

 

Step 2

Clean up the old caulking. Remove any bits of old caulking (you may need to use a moist towel for this) and be sure the tub surface is dry.

 

Step 3

Apply new caulking. Lay an unbroken bead around the seam of the tub.

 

Step 4

Smooth the caulking with your finger or a damp paper towel. This will form an unbroken and watertight barrier. Allow 24 hours for the caulking to dry.
