Our office was paneled over cement block and had seams skimmed then one layer of wallpaper primer and a layer of wallpaper. In updating out office we stripped all wallpaper and after skimming the wall and painting the seams from the paneling cracked all the way from floor to ceiling, even the plastic molding cracked. How do we repair this? Won’t it crack again if patched and painted?
Painted paneling seams cracked.
