Painting of corrugated iron catchment tank

[ef9]

I want to use the XO Rust paint from the Orchidland True Value, but it says that you cannot use it on roofing.

Why is that? I don't plan on drinking from the corrugated iron siding used on my catchment tank.

Either the XO lacks UV protection and would fail in the sun. Or it might refer to new galvanised where it wouldn't stick. Or there are toxins making it unsafe for drinking.

A topcoat should remedy the first UV problem. If galvanised but weathered no problem. As to toxicity, will the next person use it for drinking?

Or when all else fails, follow instructions.

I'm painting the sides of my catchment tank.

Make sure topcoat is High UV rated. Toxicity not a matter.

Scuff sand "wet" with coarse black waterproof paper, the whole surface, and clean rust good. Preperation preperation!

I believe that when painting galvanized steel you have to prime with a zinc chromate before top coat or the paint won't hold. And like qtill mentioned.... prep is key for a long lasting job.

Royal, if galv is new and shows glss, it could use primer, but even new work can be etched with any common vinager, stand, rinse, and ready to use. 6 months of exposure does the same.

Unfortuantly prep always trumps!

I know someone that painted their catchment a light green and then used palm fronds as a template to paint the rest a darker green. It looked great and totally blended in to the landscape.

A good solution and one used most often on ships and maritime metal is Ameron 235 "barrust" paint. US Navy option 1 for rust control, and it's rated for 10 year immersion. You can buy it at Big Island Marine, and it isn't expensive. Use that for a primer base coat and a cheap enamel like rustoleum for a top coat, touching up when needed. It's a real fix.
