Quick question...Starting a project next week. I have lots of wallpaper to remove from a two bedroom apartment, then going to prime and paint. I also have rooms with vibrant colors that are not wallpapered. Eventually the apartment is going to be painted Decorators White to sell. I'm looking for opinions on primer. Do I go with two different primers, one for the wallpaper walls and non wallpapered walls or just one primer for all. I plan to use Gardz on the wallpapered walls before priming. TIA.
