Hi all, looking for advice on repairing my newish shower cubicle which has leaked at the trim corners. Cubicle built to plasterboard which has completely failed so I've chopped out the first row of tiles and left the rows above in position as the plasterboard is sound/dry. My intention was to use hardi board to make good the wall and tape the joint with the existing plasterboard using bal tape and then tank the repair with bal tanking kit. The plasterboard is 10mm thick, so I was considering using the 6mm hardi board fixed onto supporting battens that will bring the surface flush to the existing plasterboard, then re-tile using good quality adhesive and epoxy grout. That was the plan but I've just seen 10mm wedi board which would appear to be more straight forward. If I use that in the same way, will it take bal tape to cover the joint or would I have to use the wedi tape? As well as that, I don't want to use a another trim strip and have decided to tile onto the bal tape where it seals around the tray. Never done that before and will only be able to get about 5mm onto the top of the tray proper as the tray has a curved edge. Doesn't seem like a lot of surface and I can't widen it as the tape would show out from the tiling. If about 5mm of tape is OK, would it be correct to use silicone sealant on top of the dried/tanked tape before the tiles were replaced and then use silicone sealant as the final seal around the gap between the tiles and tray top.
Thanks for reading and looking forward to your opinions.
