Best Airbrush for Miniatures (2026): Detail, Base Coat and Budget Picks

Nozzle sizes for each stage of a miniature

Stage	Nozzle	Why
Priming	0.4 to 0.5 mm	Primers are thicker; Createx calls for 0.5 mm or larger for its primer-sealer
Base coats and zenithal highlights	0.3 to 0.45 mm	Even coverage without clogging
Highlights, faces, freehand	0.15 to 0.25 mm	Fine lines; needs thin paint and low pressure
Varnish	0.4 mm and up	Even coat, thicker medium

Golden notes that paints of 35 to 60 centipoise suit 0.18 and 0.2 mm nozzles, and that not every color suits very fine tips. Thin, transparent paints work best in a detail airbrush.

Paint and pressure for miniatures

Vallejo Model Air is made to spray from the bottle; Vallejo gives about 15 psi, and 15 to 20 psi for its Surface Primer. For detail at 0.2 to 0.25 mm, thin a little more and drop the pressure. Our airbrush paint guide, primer guide, PSI chart and thinning chart have the makers' figures.

One airbrush or two?

One 0.4 to 0.45 mm airbrush covers priming, base coats and zenithal highlights, which is most of the airbrush work on a miniature; brush the fine detail. Add a 0.2 to 0.25 mm airbrush when you want airbrushed highlights, faces or freehand. Two airbrushes also save cleaning: primer in one, colors in the other. A compressor with a tank and two outlets, or a dual holder, makes switching easier; see airbrush compressors.

A simple zenithal priming routine

Zenithal priming uses the airbrush to pre-shade a figure before painting:

1. Prime the whole figure black from every angle.
2. Spray grey from about 45 degrees above, so it lands on upper surfaces.
3. Spray white straight down from above, lightly, so only the highest points catch it.

Vallejo's Surface Primer comes in black, grey and white, sprays at about 15 to 20 psi, and Vallejo recommends several thin layers. Thin color coats over the result let the shading show through.

Set up for small figures

• Mount figures on a handle or cork so you can turn them without touching paint.
• Spray in a booth vented outside; see spray booths.
• Prime in thin coats so detail is not filled.
• Clean the detail airbrush often: tip dry is the main problem with fine nozzles (see how to clean an airbrush).

Common mistakes with a miniature airbrush

Miniature airbrushing goes wrong in a few predictable ways:

• Over-thinning ready-to-spray paint. Vallejo makes Model Air to spray from the bottle; if you do thin it, Vallejo's ratio is 3 parts paint to 1 part Airbrush Thinner.
• Soaking the whole airbrush. Iwata's cleaning guide says never to soak or "wet dock" an entire airbrush; soak only the nozzle and caps, for no more than 10 minutes.
• Leaving paint in the cup. Iwata says never to store an airbrush with paint or cleaner in the cup.
• Wiping the needle backward. Iwata says to wipe it only toward the point, so you do not puncture yourself.
• Painting without spares. Iwata suggests an extra needle and nozzle if you airbrush often, since both are easily damaged.
