I have recently decided to remove some wallpaper in my dining room. The problem is, the wallpaper (still can't tell if there's 1 or 2 layers)has been painted (I think with just one coat). It's already bubbling and peeling in a few spots. I'd like to remove it as there are vertical lines running up and down the walls. Will the paper tiger work through a thin layer of paint? Is there anything else I can do? I was just going to paint over it again, but those darn lines are already getting on my nerves! Thanks for the help!!
