I'm looking to help a friend out by resealing there shower tray before they have a more major problem. Ideally I should rip out what is installed and start again but sadly there is not enough money in the pot for that.
The shower is in an alcove, is not tanked and has suffered a very minor leak in the bottom corner where a plastered block wall joins a plasterboard wall. It would appear the grouting between the bottom and second row of tiles failed and luckily the water damage was minimal and easily fixed.
The 795mm square tray is in a 845mm wide alcove so there was a horizontal ledge of tile between the wall and the top of the tray, which I know is not a good idea. I've removed the bottom 2 rows of tiles and the ledge of tiles so that I can put some form of tanking in.
All the tanking kits I can find are for much larger jobs and would mean a lot of fairly expensive product left to go to waste. I have tin of liquid damp-proof membrane (LDM), which I'd like to use, but it would seem that this is no good, in part, because it wouldn't support itself across the gap between the walls and the side of the tray; but then neither does the proper tanking compound.
If I embedded some fibreglass or polyester clothe within several coats of LDM, thus supporting the LDM where it bridges the gap would this be OK? I've stuck a piece of tile coated with the LDM to another piece of tile using waterproof tile adhesive and they are well stuck together; I've been unable to break the adhesive to LDM bond (the pieces of tile shattered first, although with much twisting with 2 pairs of 10" pipe wrenches I did manage to break the LDM away from the back of the tile.
Any help would be much appreciated.
