Hi guys,

I'm in the middle of rebuilding my door hinges & have disassembled & media blasted them. After reassembly I'm giving them a coat of epoxy primmer to keep them from rusting until the jambs etc, are painted. The question is will there be a problem with the top coat of paint bonding to the epoxy (hinges only)after sitting for months without scuffing.

Should I put a coat of 2k primmer over the epoxy until top coat?

Than you in advance.

Epoxy must be sanded if it has cured.

You could put an extra coat of epoxy on them (maybe 3 instead of two) and plan to sand before paint. That is, scuff. Epoxy sometimes doesn't agree with sandpaper (doesn't feather well) so its best to just scuff with a red pad and apply sealer before color. But if you scuff, it will stick no matter how old. As long as it hasn't sat outside and faded.

If I were you, since the hinges are blasted and you'll have to sand or scuff either way, I would go ahead and put down two coats of your 2K primer after two coats of flash-dried epoxy. The extra fill will make them look nicer and they will be easily sanded once paint day gets close.

You know I've been thinking... I'm going to seal them up in a vac-bag, prime & paint them later.  Wink
