Hi, how come I have wet patches on my wall? I have had it for a long time. The wall was redone: new plasterboards & new plastering. Its been like a year now. Anyone know why I have these massive patches/dots? I had it across all the wall. If I put wallpaper over it will the patches be visible on the wallpaper? I have attached a picture of the wall.
