Tiling on damp cement type plasterboard

[inigo]

Hi everybody,

On a mission to sort out my bathroom problems now that I have been made redundant!

I have taken down the tiles in my bathroom shower area where water was leaking for months through a bad seal and soaked though to the wall in the next room. The wall (not plasterboard but a grey cement type board, on breezeblock) is damp in the bottom third but very secure against the wall.

View media item 49802
Should I dry the board out completely before tanking/putting new tiles up (is this even possible in a reasonable time) or will I need to replace the whole cement type plasterboard (with aquapanel or tile backer etc) ?

Thanks!
Inigo

Always best to let the area dry out, methinks - if only for the benefit of any timber etc thats lurking down there.....
Your pic is a wee bit confusing - the pink area looks like plaster, but the grey area is like cement render?
Aquapanel is an excellent tiling medium...it doesn't repel water, but water doesn't deteriorate it.

Inigo; I think we’ve already established it’s probably not plasterboard & you need to check exactly what it is you have.

I meant post the Tiling Forum with further info after you checked it out, not ask the same question which will only result in you getting very similar response which is that you can’t tile onto a damp substrate whatever it is!

Thanks guys, and you're right Karis, I just wish I didn't mess up and post in the wrong sub-forum in the first place

I will endevaour (?) to find out what the board is and get back to you- deffo a board. John - it had been skimmed with plaster which came of like sludge - hence why Karis thought it could be swapped with an image from the Mars rover!!!
