The home that we have just purchased has a serious bathroom problem. The previous owners removed wallpaper from the walls but didn't bother to remove all of the old wallpaper paste. They then painted over it (a hideous pepto pink I might add) and now I'm not sure how to proceed with repainting. The walls are plaster to begin with and have their own problems being uneven (really uneven) and I'd like to paint it a periwinkle blue. Any suggestions? I really didn't want to have to get out the palm sander but will do anything to get rid of the old "wallpaper netting" running throughout the walls. Thanks in advance
