Hello to All,
My old barn/shop metal roof is getting more rust at time marches on.
It has not rusted through, and is still pretty sound but ?for how long?

Please give me your thoughts on which coating material to consider.

EPDM, poly, liquid rubber, etc.

Thank you. Norris

If it can still be coated, ie no perforations the one of the best materials would be aluminum roof coating, we use it all the time, not the Home depot brand but a good brand like Bull Dog or Karnack, about $75. a 5 gal pail, mop it on with a 3-4 knot brush.
Good luck,

None at this time.
Reminds me of a project years ago. A friend had picked up a 50x100 steel barn for cheap and re-erected it on his property. The roof tin had a lot of surface rust so he enlisted a bunch of friends to wire brush it and coat it with the aluminum coating.

It was not a fun job at all. Having moved on and lost contact, I have no idea how long the coating held up. I would think that the rust would remain active even with the coating and continue to deteriorate the metal.

I dunno', would it be more cost effective long term to go with new tin?

Yep, I've had more experience than I wanted with Kool Seal, but it's primarily for sealing seams and cracks, not for a complete coating (unless there's been some major changes in recent years). And while I don't remember the name of the stuff, there are much better products on the market than Kool Seal.

start with "rust converter" as your primer, then paint with whatever you want.

JB-

Will this Bull Dog coating seal the metal roof where nails are fastening it down on my pole barn?? It was constucted several years ago and the rubber washers are all but gone and it is showing small rust areas. Would this product be ideal for coating the whole roof or is there a better product??

I used a cheap silver colored Walmart(if I remember correctly) fibered mobil home roof coating on an old building several years ago. The coating worked OK, but the building got pretty rough after a windstorm a couple of years ago. I dozed out a big hole last spring a pushed the building off in it and burned it. That roof coating and the old masonite siding burned like they were made of diesel fuel:eek:. You might want to check the flamibilty of anything you get.

Check with a professional paint store. There are much better materials then Kool Seal. There is at least one that give a white flexible coating.
