It’s important to make sure there are no cracks or gaps in the caulking around a bathtub, which could allow water to penetrate into the wall causing rot and mold.

To caulk around a tub:

• Use a utility knife, putty knife, or chisel to remove the old caulking around the tub.
• Remove any remaining dust or debris in the joint between the tub and wall.
• Apply a bead of mildew resistant, 100% silicone bathroom caulking to the crack around the tub.
• Smooth out the caulk with a damp finger.
• Allow the caulking to cure for the recommended time before using the tub.

Before recaulking around a bathtub surround, it’s important to remove the old caulk so the new will stick properly. Use a utility knife or putty knife to cut or scrape out the old stuff, and then brush the dust and debris out of the void. Apply the new silicone caulk so it fills the void and overflows slightly. Then, with a damp finger, you can smooth out the bead of caulk, and remove any excess to create a clean finished line all around the tub.
