Other forms: sealants
A sealant is a paste squeezed into a gap so water cannot pass. Apply the sealant, silicone sealant, let the sealant cure.
Silicone is the usual kind round a bath, and it must go onto a dry surface or it will not stick. It stays flexible after curing, which is the point, since the joint it fills is one that moves.
