Hey there!

How many PSI should I use to basecoat my figures with vallejo primer? I use an Harder & Steenbeck Ultra airbrush with a .2 needle.
I am very new to airbrushing, so a rough guideline when to use higher or lower PSi would be appreciated aswell.

The .2 needle's very fine. If you can swap out for .4. You're extremely likely to get nozzle clogs with a .2

I shoot at around 20psi for priming, and most purposes.

With a fine needle you'll need thinner paint (yes, even the Vallejo Model Air).

In general, opaque coats will be thicker paint mix, higher pressure. Less opaque you want thinner paint, less paint flow, higher pressure for longer distance 'filtering'. For fine spray, lower the pressure and paint flow and get in closer.

Personally i sit around 17 PSI

Thanks, fortunately I can get another needle for my brush

will put it on my shopping list, but for now I will have to go with the .2 needle I guess.

Priming 22-24 psi

General work 17 psi

Fine work 11-12 psi
