Crunch1945 Posted February 12, 2016 Share Posted February 12, 2016 First time priming my models, so i finish priming them, waited about 24 hours and they weren't dry. They had a few wet looking spots and was still fairly tacky, so I waited another 5 hours (almost 30 hours now). And the models still aren't drying in those spots (the rest of the models were dry except those spots). So the question is two-fold. A. Did I over prime the model, or what is happening if you guys know? B. Secondly how do I fix this, or do I just wait it out for it to dry? Thanks all.

Grotsmasha Posted February 12, 2016 Share Posted February 12, 2016 That definitely sounds weird, 30hrs is excessive by anyone's count. A couple of follow up clarifications, 1- Brush or Spray Primer? 2- Plastic or Resin? The fix in the meantime, wash all models parts in warm soapy water to remove potential mold-release agent (this can be done on the sprue), particularly important with resin, allow to completely dry. If spraying, do so in a cool place out of direct sunlight and as little wind as possible. The models should be touch dry ~10 to 15mins. Link to comment Share on other sites More sharing options...
Crunch1945 Posted February 12, 2016 Author Share Posted February 12, 2016 Used Spray primer, Used Rust-Oleum American Accents Matte Black Primer, kind that bonds to plastics. And these are plastic minis. Also I did wash them a few days ago, and it's not that the paint is peeling, it's like a portion didn't dry on top of the coating (only did the one coat). And it's seen near the bottom of the model, ie feet base, and some in the recesses of the model. Side note: I did spray it a fairly cool climate, my garage, winter right now so it was about 20F outside. Waited about 40 minutes to allow for drying then brought them inside to finish drying. Thanks for the help by the way, this is my first time painting miniatures. Link to comment Share on other sites More sharing options...
Grotsmasha Posted February 12, 2016 Share Posted February 12, 2016 I know some use a hair dryer to speed the drying process. Link to comment Share on other sites More sharing options...
Brother Pheidias Posted February 13, 2016 Share Posted February 13, 2016 Sounds like dodgy primer or some form of residue, that the primer is reacting to. Link to comment Share on other sites More sharing options...
JeffTibbetts Posted February 13, 2016 Share Posted February 13, 2016 Yeah, that really shouldn't happen with spray on plastic. I do wonder if you got a bad batch. Link to comment Share on other sites More sharing options...
Crunch1945 Posted February 13, 2016 Author Share Posted February 13, 2016 I know some use a hair dryer to speed the drying process. Yeah it did help a little, but found that just removing most of it with a paper towel worked well (though took about 2 hours ). I'm thinking that i left a finger print on the models when I removed them from my case, that's what happened? Anyways guys, thanks for the help, started painting my guys. Almost done with 5 of them. Thanks All! Link to comment Share on other sites More sharing options...
Brother Pheidias Posted February 13, 2016 Share Posted February 13, 2016 Grease from your fingers really shouldn't be enough to cause primer to not dry, unless you're covered in engine-lubricant or somrthing though.But glad to hear it's working out afterall!

I regularly do mine in -20c and lower. Damned if I'm going to stop work because it's winter 8 months out of the year and I've never had serious issues. This sounds like some sort of lubricant one would have lying around in the garage ended up getting on them imo. Link to comment Share on other sites More sharing options...
