Damp wall going to be tiled - TilersForums.com

hi guy gonna keep it short have bit of mold on bathroom wall coming from a cupboard in the stair to the flats, I was gonna start tiling next week but unsure now, I had a builder in he seen I had a tanking kit and said paint wall with that mold won’t come through, I’m unsure tbh just want second opinion?

Thanks in advance any advice appreciated.

I no expert . Black mould is condensation. Treat that then tile . But you are going to have to remove your wall paper at the very least.

It’s still to be stripped at weekend just wanted some advice first tbh

 

[Qwerty]

Eliminate all possible avenues of cause of mould first, but as said, likely to be just condensation

thanks for opinions guys, had rising damp on outside walls, been treated with injections might need to get damp guy back

isnt the injections usually the cause of damp in most cases ?

Sort the mound before you do anything. Tanking will not stick to a damp surface. It may appear to do so.......but it will only be like a sheet of wallpaper.......and peel off.

No . They are the cure

When got rest of damp done was told wasn’t damp enough to need treated, iv since removed wallpaper and it just seemed to be on top of the paper...... thinking condensation il leave it a while see what happens. Cheers for comments
