I have a similar situation in my basement.  Most of the blocks in the bottom two rows on the north wall are crumbling.  There are addtional spots here and there on the remaining parts this particular wall.  Do I need to remove all the paint on the wall before using the epoxy patching compound or just scrape away the loose paint?
