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.

What is the coverage per bucket on flat concrete tiles?

Asked by: Tony
I KNOW that concrete tiles will not soak anything up (or very little). We had concrete tiles on the home I grew up in and we "white washed" them every two or three years. I wish we would have had THIS stuff! Unless you have a lot of cracks that will eat it up (and I mean a lot!), you will get at LEAST 50 sq ft per gallon, and probably more (250 sq ft+ per bucket). Someone wrote in their review they got close to 60 (almost 300 sq ft for a 5 gal bucket on a fairly solid roofing material). This stuff is VERY thick and does not soak in unless you have a MUCH softer material like I had. They say it is designed more to adhere to materials (and it SURE does). I put it on 18 year old asphalt shingles and I got 44 sq ft per gal (220 sq ft per bucket) and I put it on thinker, intentionally, too. You will get FAR MORE, for sure, as long as you spread it out as you go and do not let it pool up in sections. Just keep rolling until it won't spread any more, then go back for some more. And MAKE SURE RAIN is not headed your way. I lost a whole bucket and 2 hours work to a FREAK morning rain shower - it got washed off into the gutter. Very depressing. Good Luck!

The product was easy to apply and provided an even nice clean finish. The only issue I had was it rained the first night I applied the coating. It came off in a small area and I just applied the coat again before applying the final coat.

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.
