How to Paint Over Wallpaper Paste

After removing old wallpaper, you may find that lots of wallpaper paste is firmly stuck to your walls. There are several steps you can take to remove it, but even after trying various methods, it may still be hanging on. You can paint over the wallpaper paste without completely removing it. While this won't produce the smoothest possible finish, with the right tools, you can create beautifully painted walls, even with the stubborn paste still stuck to them.
