We have your standard bathtub / shower set-up. The previous owners of this house used some kind of lino instead of tiles to cover the walls above the tub. Not ideal but it seems to work fine.
The issue is the grout (caulking?) that makes a seal between the bottom of the lino/tiling and the top edge of the bathtub. The lino seems to be slightly curving, away from the wall, and the seal of the grout is broken.
We tried re-caulking it a little while ago, using the appropriate bathroom stuff, but the fact that the lino is curling up a bit makes it hard to get a good seal.
Any ideas? We didn’t remove the old caulking before we re-did it, so I’m assuming that’s a big part of the problem.
a) how do I remove the old silicone/caulking stuff?
b) what is the best method and product to replace the caulking and create a new, watertight seal?
c) I think at Home Depot I have seen a kind of white “tape” for this purpose - has anyone tried it?
Any help is appreciated!!!
