Tiling to old cottage bathroom walls

Did think about that, but if the damp gets behind the wedi would it not trap it and make it travel to the room next door? Or since it's lime and horse hair would it breath it's slef back out?

Dunno! You could go in circles worrying about damp.
I would simply offer a guarantee that the tiled room would now be damp-free. Where it goes from there is their problem...
They could take it, or leave it...

Very true mate, he is understanding about the issues of this nature it is a 17th century cottage after all. Was hoping to have something else to take to the table if possible but I will run through options with him and see tomorrow. Cheers gents

im hoping someone has a idea i haven't thought of for this one, tomorrow i night i have to go and price up a bathroom in an old cottage, i did the floor earlier this year, ended up having to put down an epoxy based dpm, with all relevant parties contacted, tec depts, a damp specialist etc etc. now the customer wants the ground floor bathroom fully tiled, the walls are flint lime and horse hair, im pretty sure it had that corrugated bitumen wall dpm installed in the 50s/60s then hardwall and skim over that. but not all areas have this as there is still a couple of little damp spots showing through on 1 external wall. my big question is, it is small room already i really cant afford the space to build a stud framework inside of the existing walls, if i batton it off the walls and fix to that i will penetrate any existing damp measures that are in place and i really wouldnt trust directly fixing to the existing walls.

so you bunch of genisus's any ideas???

That plaster didn't exist in the 50s/60s

Can you instal vents to counter any humidity behind a tile backer?

Its been patched, a few times, the bottom by the door is that dpm stuff with s & c render over but most other areas that are now blown are hard wall and skim so I was assuming the render had blown and it had Ben patched at a later date with the gypsum

To the outside? They are 2 foot think flint walls, no hope of that without making a lots of mess on the outside

Pilot hole from the inside out, with tenderness, then a wet core drill from the outside in? Or bring a company in to do it. It is possible!

With old walls like that they would flint inside and outside then all broken pieces thrown in between the the walls.

Problem with core drilling in a flint wall is, you hit a flint it comes out whole and takes everything out with it. I'm in Hampshire, theres a reason we call the stuff Hampshire nugget's, it's everywhere and is a rubbish to work with lol. Cheers for the thought thou will run it past him, but tour right someone else will be coming out to drill the hole, then they can do the making good lol
