Hmmmmm. I'm thinking that taking down the wallpaper may be a bad idea. The wallpaper was adhered to what looks like unprimed drywall. And as I'm trying to get it off, I'm gouging it. That will require a lot of repair and sanding. Plus, it's probably not good to sponge hot water onto unprimed drywall, which is one of the ways I'm trying to get the wallpaper off.
So. Before I get any farther, I'm going to stop. I'll look for any loose wallpaper and remove it. Then I'll do some wall repair with leftover joint compound I have from the other bathroom. I'll prime the walls and then I'll paint. Sound good to you?
