I've removed old wallpaper from a bedroom wall and found that the concrete lintel above the window (it's a wide window, over 2m) is now exposed. The surrounding plasterwork is level with the lintel. It's an interior lintel only, if that makes a difference.
My question is, is it ok to wallpaper directly onto the lintel? If not, then what (apart from getting the entire wall skimmed) can I do?
Thanks for any suggestions.
