Tools & materials
- 100% silicone kitchen and bath caulk
- Caulk gun
- Caulk removal tool or plastic scraper
- Rubbing alcohol and rags
- Painter's tape
Step by step
- Step 1
Scrape out all the old caulk with a removal tool. Don't use metal blades on acrylic or fiberglass tubs.
- Step 2
Clean the joint with rubbing alcohol to remove soap scum and residue, and let it dry completely.
- Step 3
Fill the tub with water. The extra weight opens the joint the way it will be when someone is bathing.
- Step 4
Run painter's tape about 1/8 inch above and below the joint for straight edges.
- Step 5
Cut the caulk tip small at a 45-degree angle and run one steady, continuous bead along the joint.
- Step 6
Smooth the bead with a wet fingertip, pull the tape right away, and leave the water in the tub until the caulk cures (usually 24 hours).
