Can this coating be directly over rusty metal roofing? Following a complete power washing. ..
Asked by: Bill
Probably not. Phosphoric acid turns rust (iron oxide) into iron phosphate which is neutralized and can be painted. I hope that helps. My bet would be to have it sand blasted rather then pressure washed. Or use paint prep with phosphoric acid and let it sit and neutralize. Then pressure wash it with soapy water.

Product was shipped faster than expected too. Home Depot notified me very quickly. I only gave it 4 stars based on my experience to date, as for durability it is yet to be seen. but the product looks good, goes on well, dries and cures as advertised. I put two coats on my 21 foot trailer with a roller and have about 2 gallons left, so another coat may be in the works. Clean up is a breeze, so far I'm extremely pleased with it and the store's performance.

Rated 5 out of 5 by from Ultra silicone never zero roof coating Product is easy to use and dried fast allowing a second cost pretty quickly after the first. Expensive at $100 vs other versions by the same company . But I figure the labor is the same to spread cheap paint as it does for more expensive, better product.
