Problem spraying Vallejo Air
Posted by rdmd9 on Wednesday, February 3, 2016 6:10 PM

Hi all,

I'm new to the hobby.  Completed some plastic models when I was a kid with my Dad but now getting back into things.

Trying to airbrush a 1/72 tank with Vallejo Air olive drab.  I have very little airbrushing experience.  I primed with spray can and then airbrushed the entire thing flat black with XF-1.  The flat black went on perfect.

The next day I tried my olive drab Vallejo Air.  This is the first time I've used it.  The spray came out kind of "splattery."  I was using a Badger 200 (old) and Propel. I shook the hell out of it and mixed it with a toothpick in the airbrush siphon jar and still same thing.

I actually bought a new airbrush today - a Iwata Revolution CR with a Silver Jet compressor.  I've tephloned all the threads and the PSI is an easy 20 so I don't think that's the issue.

Is the paint bad?  Am I doing something wrong?

What are you using for thinner? I highly suggest using the Vallejo thinner only. Others have come up with some concoctions they claim work, but your best bet is using Vallejo products.

Alcohol based thinner will gum up the paint.

I tried no thinner (since it's Model Air). I also tried water, as well as Tamoya thinner.  Same results with each.  Could this be  a paint mixing issue maybe?

I always have to use a few drops of their thinner even with the ModelAir paints.  They're just a bit too thick.  Vallejo is very picky about thinners types/brands too.  If you have to buy some, buy Vallejo's.  Experiment later.

You're also going to want wait a few days before you put any masking tape on their paint.  I've noticed it lifts very easily.

If your brush is spitting try turning your air pressure down. What is your pressure now? If your at 20 cut it back to 15, this guy in the video is stating that Badger and Vallejo air seem to like about 12 psi or so. It sound like a psi problem.

Check out this video and see if it helps.

Another possibility is the tip is clogged thats causing the issue. Or a misalignment of the needle. Maybe the seal is bad too.
