How do I re-caulk my bathtub?

First, you’ll need to remove the old caulk using a utility knife. Cut along the bottom of the caulk nearest the tub, then cut the top along the tile. This won’t get all of the caulk, but you should be able to remove the majority.

Once you’ve pulled off the caulk, spread silicon caulk remover along the seam where you removed the caulk, along with any spots of caulk that you see outside of that seam.

Leave it for a few hours and then use a putty knife to go back and remove the rest of the caulk.

Wash your tub and then use rubbing alcohol to wipe down the seams where you removed the caulk. This will kill any residual mildew or mold.

Once it’s completely dry, run painter’s tape along the edges of the tub and wall, leaving room for your new caulk line – about ¼” from the seam on the wall and the tub.

Now fill your tub with water so that the weight of the water slightly separates the tub from the wall. This separation is minimal, but it’s normal. It occurs every time you fill the tub. And by filling the tub before you caulk, it means any stretching and cracking due to this separation will be minimal.

Caulk one line of the tub at a time. Start in one inside corner and caulk to the other inside corner of the tub along the back wall. After that, caulk from one corner to the outside of the tub. Repeat on the other side of the tub. For each caulk line, get your fingers damp and smooth out the caulk lines you’ve just applied. After 15 minutes, remove the painter’s tape.

Drain the tub. Then let the caulk dry for at least 24 hours before you use the tub.
