I absolutely despise DIY of any sort and am basically lazy so looking for the path of least resistance here (short of paying someone else to do it which can't currently afford).
One of the bedrooms in our new house had what I thought was a feature wall in patterned wallpaper and then three painted walls. Just finished scraping off the paper from the feature wall, plaster etc in perfectly good nick underneath. Have just discovered the other three walls also have paper on them under the paint, that lining paper stuff people use and then paint over. Do I absolutely have to remove this or can I prime it and paint over the top of it?
