Have a house from 1968 with a basement in a split-level design. The house has not been re-drained. When we removed the original wallpaper on the exterior wall in one of the rooms, it looked like there was moisture in some areas. However, the wall is not noticeably damp, and the basement floor is otherwise dry. The question now is how we best handle this. Attaching some pictures so you can see. Is it enough to paint with silicate paint? Or what measures are recommended?
