Painting over fibered aluminum roof coating
We painted a metal roof last year for a customer. We power wire brushed and pressure washed the entire roof , but there were some spots that were still rough and rusty,( we removed all loose scale ,paint ,rust ,etc.) so we coated first with fibered aluminum, then painted black with oil based paint . It seemed to stick well and looked good. Now the paint is blistering , so I need to repair it.
Was it a mistake to paint over the fibered aluminum? (evidently
)
Any suggestions?

when doing that use an asphalt primer for the entire roof,then look at elastomer/acrylic style paints like gaf`s solar seal-----do you believe they make you wait 180 seconds between posts.makes you want to omit the post instead--weird,wonder why they would have that requirement ?????

The fibered aluminum paint is great for painting rusty metal but shouldn't be used as a primer. When painting, use a rust inhibitive primer [solvent based] and then an oil base paint for a top coat.
An elastromeric coating will not hold back rust but can be used over primer or a tar sealant.
The 3 min delay is to help prevent spam - doesn't always work but atleast it keeps it to a minimum

the reason for it is because this is a roof,and as well as painting,it seals up any possible leaks,which paint doesn`t do
