Why Caulking Matters
The caulk around your bathtub keeps water from leaking into walls and floors. When it cracks, shrinks, or grows mold, moisture can cause hidden damage and costly repairs.
What You'll Need
- A utility knife or caulk removal tool
- 100% silicone or siliconized latex caulk
- A caulk gun
- Rubbing alcohol and a clean cloth
- Painter's tape and a caulk smoothing tool
Step 1: Remove the Old Caulk
Use a utility knife or caulk removal tool to cut and peel away all the old caulk. Remove every trace so the new bead can adhere properly.
Step 2: Clean and Dry the Surface
Wipe the joint with rubbing alcohol to kill mold and remove residue. Let the area dry completely, as caulk will not bond well to a damp surface.
Step 3: Tape the Edges
Apply painter's tape along both sides of the joint to create crisp, straight lines and keep the caulk from smearing onto surrounding surfaces.
Step 4: Apply the Caulk
Cut the caulk tube nozzle at a 45-degree angle and apply a steady, even bead along the joint. Work in one continuous motion for the best results.
Step 5: Smooth and Finish
Run a smoothing tool or wet finger along the bead to press it into the joint. Remove the tape immediately, then let the caulk cure fully before using the tub.
