We just recently bought our first house, and it has tons of floral wallpaper. We're in the middle of trying to take the wallpaper down in the kitchen so we can paint the walls, and after taking it off of our first wall, I think we've run into trouble. The wall underneath the wallpaper is really gross, and I think that must be why they covered it in wallpaper. I've attached a few pictures. If at all possible, we'd like to repair the wall so we can paint it. There seems to be some gray textured paint on the wall that was pulled off with some of the wallpaper. Also, the center of the wall seems to have at one point been a window? And is now plastered over. Also, right below the heater is a wooden block stuck into the wall, which we'll need to cover before we paint. This is what we're thinking - sand down the plaster in the middle and all the sections that don't have texture, then buy one of those texture paint cans and spray those areas with texture. Do you think this will work? Do we need to do anything else? And if so, how???
