I agree completely...however use the cheapest throw-away sprayer you can get for the project. NuWall or RENEW will destroy the guts to your sprayer. At least in my experience with strong mixtures.RENEW equipment cleaner from C.A.R. products works well. We spray on with pump up sprayer, brush it around using an old foam brush, let it dwell 5 minutes, then rinse off with hot water. It does the trick no matter how dirty the walls are.
