After 18 years, the wallpaper was finally taken down. Didn't have too much trouble but a lot of the glue/sizing is still on the wall. Cleaning it off is a pain. When asked for advice, the lead guy said that since I had cracks to repair, I would most likely end up skimming the whole area and so it wasn't necessary to take off the sizing. Is he correct?
