Airbrush Buying Guide for Scale Modellers

Thinking about upgrading your model painting with an airbrush? Whether you’re just getting started or ready to go pro, this guide will help you choose the best airbrush kit for your modelling needs.

Why Use an Airbrush?

Airbrushing delivers smooth, even coats that brush painting can’t match. Perfect for large surfaces, subtle shading, camouflage, weathering effects and precise detail work. It saves time, reduces brush marks, and unlocks new techniques like pre-shading and modulation.

Types of Airbrushes

  • Single-Action: Paint flow is fixed; the trigger controls only air. Easier for beginners, but limited precision.
  • Dual-Action: Trigger controls both air and paint flow. Press down for air, pull back for paint – more control, better results.

Top Feed Types

  • Gravity Feed: Paint cup is on top. Uses lower air pressure, ideal for fine detail and less paint waste.
  • Siphon/Bottom Feed: Paint is pulled up from a jar. Better for large jobs but needs higher air pressure.

Nozzle Sizes Explained

  • 0.2mm–0.3mm: Fine lines, small details (ideal for 1/72–1/48 aircraft, figures).
  • 0.4mm–0.5mm: Good general-purpose size (tanks, aircraft, dioramas).
  • 0.5mm+: Coverage, primer, varnish, terrain models.

Do I Need a Compressor?

Yes. Most modellers use oil-free piston compressors with air tanks for steady pressure. Look for:

  • Auto on/off
  • Regulator + moisture trap
  • Quiet operation (under 50db if indoors)

Beginner Airbrush Recommendations

If you’re new, we recommend a dual-action gravity feed airbrush with a 0.3mm nozzle. Kits like the Ultra Two-in-One by Harder & Steenbeck or the SMS Starter Airbrush Kit are great entry points.

Recommended Airbrush Brands

  • Harder & Steenbeck: German precision, easy maintenance, modular parts
  • Iwata: Japanese quality, fine control, durable
  • Sparmax: Great value compressors and kits

Essential Accessories

  • Airbrush cleaner & cleaning pot
  • Paint thinner (acrylic or lacquer)
  • Quick-release hose connector
  • Spray booth if working indoors

Final Tips

Start simple. Practice on scrap plastic. Always clean your airbrush after use. Most importantly—don’t be afraid to experiment.
