Is Airbrushing Miniatures Hard for a Beginner?

Updated · by The Pigmentum · frames from Episodes 03 and 04

She primes with an airbrush, gave herself one hour to paint a whole miniature with nothing else, and fought a melting base coat on her biggest model. This page gives the general beginner basics and shows exactly what happened when she tried.

Short answer: the basics are not hard. Priming and smooth base coats come quickly; the part that takes practice is getting the paint thickness and air pressure right, and keeping the airbrush clean. You do not need one to start. She uses hers for primer, tried a one-hour airbrush-only miniature in Episode 04 and calls it “not really successful”, and in Episode 07 learned that “too thick, it will clog. Too thin, the coverage is bad.”

01Do you need an airbrush to paint miniatures?

No. General practice: most beginners prime with a spray can or brush-on primer and paint everything else with brushes. An airbrush is a speed and smoothness tool, not an entry ticket. It earns its place when you prime a lot of models, paint big flat areas (tanks, monsters, cloaks), or want soft top-down light.

Honest note: she has not made an airbrush tutorial or said which airbrush she owns, so this page does not name kit. What is on film is below, quoted in her own words.

02What is an airbrush good for on miniatures?

03How do you airbrush a miniature, step by step?

General practice, not a claim about her exact airbrush, pressure or paints:

  1. Spray where the air is handled: a spray booth or a well-ventilated space, and a mask, especially with primer.
  2. Mount the model on a handle so you never touch the paint. She holds hers on a painting handle in the booth.
  3. Thin the paint to roughly skimmed-milk consistency with airbrush thinner, or use airbrush-ready paint. More on thinning: how to thin paint.
  4. Test on your hand, a card or a spare part first to check the flow before it touches the model.
  5. Spray light passes from a short, steady distance, keep moving, and start and stop the spray off the model.
  6. Let each coat dry before the next. Two or three thin coats beat one wet one.
  7. Clean the airbrush straight after, flushing with water or cleaner until it sprays clear. Dried paint is the usual cause of clogs.

04What happened when she airbrushed on camera?

Episode 04: one miniature, one airbrush, one hour. Her first two miniatures took about 20 hours each, so she set a challenge:

“My last two minis took me about 20 hours each to paint. At this rate, I will have a fully painted army in 2047. So, today I have one miniature, one airbrush, one hour.” — Episode 04

She got excited about the face (“Ooh, his face. That’s so good.”), caught herself spraying the hand by mistake, and at the buzzer:

“Is it really nice? I don’t think so, but it’s not gray anymore. So, that’s something.” … “I wanted to push myself to use the airbrush … And I would say I wasn’t really successful.” — Episode 04

Episode 07: the base coat that melted. On her biggest model she wanted a smooth Elysian Green base coat, and had heard it can be a nightmare through an airbrush:

“Too thick, it will clog. Too thin, the coverage is bad. At first, everything was going surprisingly well. The base coat was smooth, the colors were great. Then, I realized, what is this? It looked like the miniature is melting.” — Episode 07

Her fix was patience: “I let it dry, and I base coated it again. Base coated again. Base coated again.” Later, facing all the metal on the same tank by brush: “Secretly, I wish that I had airbrushed this part.”

FAQ

Is airbrushing miniatures hard?
General practice: the basics (priming and smooth base coats) are quick to pick up; the learning curve is paint thickness, air pressure and cleaning. Her own first full airbrush attempt, a one-hour challenge in Episode 04, she calls not really successful, though the model went from grey to painted inside the hour.
Do I need an airbrush to paint miniatures?
No. Most beginners start with a spray can or brush-on primer and brushes. An airbrush mainly speeds up priming and large base coats. She primes with one in a spray booth, and she painted metal on her Episode 07 tank by brush while admitting she secretly wished she had airbrushed it.
What can you use an airbrush for on miniatures?
General practice: priming, smooth base coats on big areas, zenithal (top-down) highlights and soft colour fades. Fine details such as eyes, edges and small trim are still done with a brush.
How thin should airbrush paint be?
General practice: thinner than brush paint, roughly like skimmed milk, using airbrush-ready paint or a dedicated airbrush thinner. In Episode 07 she sums up the problem: too thick and it will clog, too thin and the coverage is bad.
Why does airbrushed paint pool or look like it is melting?
General practice: too much wet paint in one place, from spraying too close, too long, or with paint that is too thin. Spray light passes from a bit further away and let each one dry. In Episode 07 the model looked like it was melting, so she let it dry and base coated it again, several times.
