I have stripped the wallpaper from the walls of my halls / stairs / landing in my 1930s house. Underneath the wallpaper is a green paint like layer which I believe is distemper. In places it has peeled away, leaving the walls patchy.
From what I have read here and elsewhere painting directly over it will not work - the paint will flake. Skimming it will have a similar outcome. I have read that I could stabilise it, but this would presumably still leave a bumpy finish.
I did notice that the wallpaper steamer did cause some of it to bubble and come away. Is this a good (safe for the plaster) approach to removing the rest ? I am wary of damaging the plaster underneath which is in otherwise good health. If not steaming how else can I get it off ?
Alternatively, is there something I can paint over it to smooth it out & prep for emulsion ?
I'm resigned to a lot of hard unenjoyable scraping at the moment, so if anyone has a good tip I'd really appreciate it.
