The walls are origianlly brick, covered in plaster. There are approximately 4 or 5 layers of old wallpaper and then that has been covered with another type of "plaster" (a thin, bumpy layer sprayed on) and then painted. I think the walls are very irregular underneath and the past owners has never attempted to do what I am...repairing it properly and starting with a clean wall.
Anyway, I am desperate to find solutions. I have tried steam - doesn't work. I have tried special "solution" that I wet the walls with and tried to scrape off - doesn't work.
Help! Thanks, Margaret
