Removal of White Film from Arizona Red Flagstone
After laying my Arizona Red Flagstone patio 2 years ago, I applied a "Natural Stone Color Enhancer". I think I may have used too much as a white, hard film developed soon afterwards. When the flagstone gets wet, the natural color returns... until it dries out. When it's dry, it looks whitish-gray... down right awful.
Last summer, I tried power washing it, but that didn't do anything. I'm at my wits end as how to restore the natural beauty of this stone.... any suggestions, ANYONE???
