another cottage job but walls are damp! - Tile Advice

[Handyeire]

Was out today pricing a large bathroom in an old cottage and 2 of the walls are very damp all over the wall. Its already tiled and tiles have been on over 20 years and I noticed the damp where the customer already removed some tiles. I'm surprised these tiles are still on and TBH, they are well bonded to the wall as its tough to remove them.

I'm wanting to know what procedure you'd take after removing all tiles and its time to retile again.

Sorry, forgot to mention walls. They are old stone cottages with lime or cement floated on outside and in with same.

Another question, obviously solid walls and probably about 100 years old...
