Hi folks, first post on this great forum.

I'm currently re-doing our en-suite shower as it was leaking through to downstairs (failed grout)

As you can see the tiles have been removed, I know I need to deal with the mould.

My question is, before I retile do I need to remove the skim of plaster that is currently on the plasterboard? As you can see I have lost some already when removing the tiles and in other places it is very thin.

I am worried that it is not strong enough to hold the tiles.

I plan to tank the wall with Ardex before tiling.

I'm a complete novice so any help would be greatly appreciated.

Thanks

Anyone?

My best guess looking at that is that the plasterboard needs to come off..it has possibly absorbed enough water to debstabilise it.

I would replace with Aqua panel (Cement based sheet, re-inforced with glass) then tile straight onto that. (No need for tanking.)

Thanks Wine-o

I guess at least I won't have to wait for drying out.
