Q. My son bought a house that has wallpaper in every room, and all of it is on unprimed plasterboard. Some of the vinyl paper came off, but the backing stayed. Trying to get any of it off results in gouges and all kinds of blemishes, impossible to cover. Could he skim coat the wall that has so many gouges?

A. Skim coating the gouges can work, and if it is only one wall that is messed up, it’s worth a try. For the rest of the rooms, he can paint the walls. And that goes for untreated paper, vinyl-coated paper, and vinyl paper; the latter is a little like a tight-woven canvas. Always use latex, and apply thin coats. First, an enamel undercoater or primer sealer, then one or two coats of an eggshell finish wall paint. If the primer sealer and finish coat are white, you may not need a second finish coat.
