Okay I ordered some vallejo flow improver to try it out. I use high pressure as well so that may be it.


When painting minis you shouldn't be running higher than 20psi.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10177894.page http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10177894.page GMT Problems airbrushing Vallejo Grey Primer
I use a 0,4mm needle/nozzle set at 60 PSI when priming or applying clear coats and use the primer straight out of the bottle, without any additives.

I aim for a moist consistency of the primer on the model - since the primer is self-leveling. If your primer is grainy on the model, it has partially dried before it hit the model, so I'd look at spraying distance and temperature and adjust accordingly.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10178265.page http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10178265.page GMT Re:Problems airbrushing Vallejo Grey Primer

I've primed hundreds of infantry and vehicles with Vallejo primer without any problems, so I think there must be a major difference in how we apply the primer to the model.

Now there's some difference in usage!]]> http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10178281.page http://www.dakkadakka.com/dakkaforum/posts/preList/764775/10178281.page GMT Re:Problems airbrushing Vallejo Grey Primer

Not really, painting isn't priming.
When painting, acrylic paints on minis most people use low pressure. Since pressure and nozzle dictacte working speed, i.e. how far long you can spray an area before it is flooded, in the interest of control low pressure is a very good idea.

However, when priming a model or a vehicle, I'm perfectly fine with a fast working speed, since I'm trying to cover the entire model in one neat layer of primer.
Higher pressure in combination with a bigger nozzle helps with higher viscosity materials such as primer, clear coat or Tamiya alcohol paints by mitigating the chances for clogging.
