Hi​​​​​​​

Whenever using Badger Stynylrez Primer on metal objects, i was wanting to know recoat times when applying a second coat of this particular primer. I read it dries in 8 minutes and curea in 24 hours. I read that you should wait 24 hours before painting, but i want fo k ow how long fo wait before i put a second coat of primer? Would it be safer to wait until its fully cured before applying a second coat of primer, or apply the second coat whenever the first coat isnt fully dry so maybe whenever it's still wet in a way (8 minutes later)??

Drying and curing aren’t the same thing.

Drying can mean, as I assume here, touch dry.

But curing means whatever underlying chemical process is going on has finished.

Being a primer, I’d err on the side of caution and do a second coat after the 24 hours. That’s because the curing time is likely based on a layer of a certain thickness. And it may even be necessary.

I cast silly little trinkets in pourable resin for example, and that stuff has a maximum pour depth. If you exceed that, the middle might never cure.

I may be wrong, and am of course open to more knowledgeable comments. But I’d definitely err on the side of caution, and leave it to Cure rather than just dry.

Not an expert, and not used that particular primer, but agree 100% with Mad Doc.

“Dry” is not leaving fringerprints or making a mess.
“Cured” is fully set, all the chemical magic done, good to go.

I always give 24 hours before the next step when using a rattlecan.

You definitely don't have to wait 24 hours.

When applying additional coats of that sort of primer, you can spray more or less straight away. As soon as it's 'touch dry', you can do another layer. Just wait the full curing time before doing anything else on top.

It's not really comparible to a resin pour, as the layers are so thin. If you were to apply a different type of paint on top, there's a chance it could inhibit curing, but it's fine to apply the same stuff on top. Applying multiple coats of the same stuff when still uncured is like doing a single, heavy layer of primer - the only difference being the surface finish would be much worse with a single coat.
