DIY steps
- Turn off the water supply to the tub and ensure the area is well-ventilated. Put on rubber gloves, safety goggles, and a dust mask to protect yourself from caulk remover fumes and silicone caulk. Remove any visible mildew or mineral deposits from the old caulk using a solution of bleach and water.
- Use a caulk remover to dissolve the old caulk, applying it to the affected area and letting it sit for 10-15 minutes. Scrape off the old caulk using a putty knife, taking care not to scratch the tile or tub surface.
- Clean the area thoroughly with a damp cloth to remove any remaining caulk residue. Dry the area completely with a clean towel.
- Cut the backer rod to the desired length and press it firmly into the gap between the tile and tub. Ensure it's seated properly to provide a solid base for the new caulk.
- Load the caulk gun with silicone caulk and apply a bead to the gap, holding the gun at a 45-degree angle. Use a damp finger or caulk tool to smooth out the caulk, feathering it out towards the edges.
- Allow the caulk to dry completely, following the manufacturer's instructions for drying time. Inspect the area to ensure the caulk is evenly applied and there are no gaps or bubbles.
- Clean up any excess caulk from the surrounding area using a damp cloth and dispose of any leftover materials responsibly.
