I have just plastered a bathroom wall which had an area of a tar like product on it (maybe old paper at some point?)
Anyway i pva'ed the wall and reskimmed it, but the tar is now showing through as you can see in the photo.
Does anyone know if i could just use a stain block on this problem or do i need to take off the plaster and redo it. Alternately i could tile over the area, but would prefer not to.
