Best adhesive for wet room tanking edge?

Jul 09, 2026 Last reply: 1 week ago 1 Replies

The edge of the tanking in our wet room is coming unglued. It has been re-glued once by the installer, but that didn't last.



Is there any recommended glue or other fixative for a long term fix to plaster?



Perhaps Sikaflex, for example, as used in caravans and and campers?



I assume that at least some of the problem is the plaster.



Cheers

Is this an up-stand around the edge of the floor, and could the plaster be getting damp? If either is the case I would be thinking about attaching a cover strip of some sort, so that the edge of the "tanking" isn't exposed. Depending on the situation it could be an aluminium strip or thin wooden batten ... anything that can be fixed to the wall and secure the "tanking".
