(picture below)
I am considering trying this myself but only ever done small patches in not so obvious places before now.
It is basically a kitchen I have ripped out and the walls now need sorting.
There appears to be 4 layers on the wall (except where it came off)
1. Tiles which I have taken off.
2. The tile adhesive in patches.
3. the old skim, in patches.
4 the actual wall, which feels like a softer gritty concrete. (no plasterboard)
You can see from the picture its a bit of a mess but considering trying to do this myself. The left wall and the wall at the far end I am not too concerned about as this will have iether tiles or units so can cover any small mistakes on my part.
Questions.....
What are the stages I would use to build up this wall again and what products would I use ?
