how do i seal up this bathtub!?!?!?
My sister is moving into a new apartment, and asked me to make her new bathtub deeper. i built a small wall out of redwood 2x4's with a good coat of uerathane on them, and the wall itself should be good and watertight, but the joint between the redwood and the bathtub is proving next to impossible to make watertight. i can't screw into the tub, for obvious reasons, so i have used two different types of caulk, a sealer strip made for replacing caulk, and i am not sure what to try next. i am getting really frustrated by this project, so i am wondering if anyone here has any suggestions on how to make a good watertight seal between redwood and a fiberglass tub. can anyone help?
