Try using Mastic/Silicon to give a better watter tight seal, pref non-mould.

A great explanation of caulking.

I agree, i'm going to try it.

Very thorough and entertaining.

This might sound like a silly question, but I don't know the answer: do you remove the tape immediately after smoothing out the caulk/sealant? Or do you let the caulk dry first (or will this make it impossible to remove?)

Fiberglass bathtub lip slopes toward wall where water collects. Any fix ideas besides pulling the tub?
