How to Plan a Successful Construction Project from Start to Finish

What You’ll Need

• Utility knife or caulk remover tool
• Rubbing alcohol or bathroom cleaner
• Painter’s tape (optional)
• Silicone caulk (mold-resistant)
• Caulking gun
• Gloves and paper towels

Step 1: Remove Old Caulk

Use a utility knife or a special caulk removal tool to carefully cut and pull away the old caulk. Take your time to avoid scratching tiles or damaging the tub.

Step 2: Clean the Surface

After removing the old caulk, scrub the area with rubbing alcohol or a bathroom cleaner to remove soap residue and mold. Let the surface dry completely.

Step 3: Apply Painter’s Tape (Optional)

To ensure clean, straight lines, apply painter’s tape above and below the joint you’re caulking.

Step 4: Apply New Caulk

Load the caulking gun and apply a smooth, even bead of caulk along the joint. Keep a steady hand and move slowly.

Step 5: Smooth the Caulk

Use a caulking tool or your finger (with gloves on) to smooth the caulk line. Wipe off any excess with a paper towel.

Step 6: Let It Dry

Allow the caulk to cure for at least 24 hours before using the tub or shower. Check the label for exact drying time.
