Damp Bathroom Walls

[Tile Shop]

Scenario:

Very old terraced house - downstairs bathroom - brick walls - bonded and plastered (about 15 years ago it was completely stripped and redone) - damp coming through from outside - mould behind the tiles and in the plaster - tiles fall off - needs re-tiling

Damp problem has not yet been addressed so from here, what will be required from prep to tile? Can the damp be fixed? or will boarding out with Marmox fixed with adhesive and screwed be a solution to block the damp from coming through?

Any takers?

Depends how far they want to go, strip to brick, have damp injection into brick, then tank the room, then start thinking about boarding with something waterproof

 

[White Room]

As Said damp injection, then render wall with integral waterproofer/Sovereign Renderlite after injection.

I'd wait till the damp was sorted 1st otherwise whole area will need tanking.

don't put bonding/hardwall/ or anything else apart from sand and cement on the inside of an outer solid non-cavity brick wall. The others draw in damp.
