Old style tin roofing for barn

[riptides]

So what do I need to paint my metal roof? I've read I need a primer...

I don't have any old paint and the rust is just surface rust, not flaking...

I had good luck with a brand called Henry. But I forget the type of paint I used. A few years ago, I painted another building with a different brand, it was "fibered". Turned out to be a huge mistake. Did not last a year. The Henry building is still looking good, must be five or six years now.

Most of those metal paints, the "silver" roofing type, are expensive, and you have to read how-long they last.

None of my buildings got primer, all are tin roofs, just the pressure washer.

Thanks for that information... didn't know about Henry. Plan to buy it now, There is 869 Rubberized or 555 Fibered - Fibered is 7-year limited warranty and the 869 is 12-year limited warranty. So 869 is it!!!

Good luck, don't paint on a hot sunny day. Especially if you are on the roof. And wear a good pair of sun glasses.

I would use a high quality INDUSTRIAL enamel and an airless sprayer. I don't believe in PRIMER. I have been painting stuff a long time and never had an experience where I wished I had used PRIMER.
