Removal of White Film from Arizona Red Flagstone

by Jean
(Dallas TX)


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???

I too have white stuff on flagstone NEW
by: Paul

so I installed Arizona flagstone for a patio about 5 months ago and it is starting to get a chalky white film or something on it. Now I didn't put any sealer on it so it can't be "bad sealer". But should I put sealer on it? what kind? thanks.

probably bad sealer

Dear Jean,

It sounds like your sealer gave you effervescence.

You should call Prosoco at 1-800-255-4255 and see what products they recommend for your flagstone.

They also make a quality "wet look" flagstone that won't cause any problems for you.

I hope that helps you out.

Great luck!
