Can any of these products be used on drywall/insulation? Does it take direct contact to work?
I am currently trying to save a wall that is almost 400 ft. long by 25 ft high. Exterior is concrete block with metal lath, fiberglass insulation and 5/8" drywall. So far I have black mold which has been resealed, grey, green and yellow molds as well, these have been left open.
BTW, my recommendation was to remove everything but I am between two national corporations and a very large landlord. THEY are the ones determined to save this wall.
Has anyone ever tried oxygen deprevation? Would it work? A few small holes and flood the space with Nitrogen or Argon. Just thinking outside of the box.
