Short answer: Start with a dual-action, gravity-feed airbrush and a small compressor with a tank (around $100–150 total). Thin your paints to milk consistency, spray at 15–25 PSI, and learn priming, basecoating and zenithal highlighting before anything fancy. Clean the airbrush after every session — maintenance is the whole skill.

Choosing Your First Compressor and Airbrush
Compressor — buy one with a tank. A tank smooths pulsation and lets the motor rest; it’s the difference between a calm tool and a spitting hose. Noise matters if you paint at home in the evening.
Airbrush — dual-action, gravity-feed, 0.3 mm nozzle.
- Dual-action means air and paint are controlled separately (press down = air, pull back = paint). Single-action brushes teach bad habits
- Gravity-feed (cup on top) wastes less paint than siphon styles
- 0.3 mm handles both priming and detail; 0.5 mm is for terrain and basecoats
Skip the $30 “airbrush kits” from marketplace sites — their compressors lack tanks and their brushes clog. A solid beginner setup is two steps up and lasts years.
Thinning Paints and PSI Pressure Guide
- Thin to milk consistency: the paint should flow off a stirring stick like whole milk. Airbrush thinner or distilled water both work; flow improver helps
- PSI guide: primer 20–25 PSI · basecoat 20–25 PSI · glazes and fades 10–15 PSI · Zenithal highlights 25–30 PSI
- When in doubt, thin more and add a second pass — wet lines and spider webs mean too thick, spatter means too thin or too much pressure
The First Three Skills (in order)
- Priming: even dark grey coats at 15 cm distance. Rotate the model; two thin passes beat one wet one
- Basecoating: paint a whole squad in one colour session. This is where the airbrush pays for itself — 20 models in 30 minutes
- Zenithal highlighting: spray white from directly above at 30–45°. Everything below stays shadowed — then thin translucent colour over it produces instant light logic. The single most valuable airbrush technique
Cleaning and Maintenance Routine
- After every session: spray cleaner through, back-flush (cover the nozzle with a cloth and press air), wipe the needle, one drop of lubricant
- Weekly (or when it splutters): remove the nozzle and needle, soak in cleaner, reassemble carefully
- Never let paint dry in the cup — dried paint in the nozzle is the number-one airbrush killer
- Keep spare nozzles and needles — they bend, and that’s normal

FAQ
Is an airbrush worth it for a beginner?
If you’ll paint armies (not single display models), absolutely: priming and basecoating speed alone saves dozens of hours. Learn brush fundamentals in parallel.
Do I need special paint for airbrushing?
No — standard acrylics work when thinned properly. Pre-thinned airbrush lines are convenient but cost more per millilitre.
How messy is airbrushing?
Containable: low PSI, close distance and a cheap spray booth or a cardboard box keep overspray manageable. Ventilation matters for health, not tidiness.
What PSI for priming miniatures?
20–25 PSI from 12–15 cm distance, in light passes. Wet primer hides detail and runs into recesses.
