Can I use an electric sander with fine sandpaper to repair wallboard after removing 3 layers of wallpaper?

Prime the whole think with Kilz. Then skim coat, sand and repeat until the walls are smooth. Then prime and paint. This sounds like a lot of work but it's the best way to get nice walls again.
Yes, you can use an electric drywall sander and drywall grade sandpaper. If you don't have a drywall sander and can't afford one you can rent them. (Or you can buy a manual drywall sander block and paper). Be sure to cover absolutely everything in the room and close off the other rooms because that dust makes a huge mess even on small jobs! Also, be sure to wear a mask because those particles are not good for your lungs!

I have removed wallpaper in my bathroom. The sheetrock walls were damaged with gouges, backing paper tears, fuzzy backing paper surfaces, etc.
