How to Use an Airbrush

Introduction

Aerosol spray paints can be used to apply an adequate finish to most modeling projects, but hobbyists who get serious about finishing their projects will want to use an airbrush for the best results.

Instructions

Difficulty: Moderate

Steps

1

Step One

Use an airbrush when you want to paint thin lines, cover large areas with an even coat, highlight models with subtle changes of tone and mix unique colors.
2

Step Two

Make your first airbrush a good-quality, single-action, external-mix unit with a compressor.
3

Step Three

Move up to a double-action airbrush, which controls paint volume and air volume with a single lever, as you become more competent.
4

Step Four

Learn about air compressors. Diaphragm compressors are inexpensive, but pulses of the diaphragm can sometimes be seen in the paint finish. The best choice is an automatic-reservoir compressor, which does not run constantly but maintains the constant, steady pressure required.
5

Step Five

Remember, many expert painters suggest that moisture traps and a gauged, pressure-regulating valve are worthwhile accessories for a beginner's airbrush unit.
6

Step Six

Build a simple paint booth with an exhaust fan. Keep a paint respirator handy and use it faithfully.
7

Step Seven

Be sure the paint you are using is appropriate for the material used in the model's construction. Some plastics require special paint.
8

Step Eight

Check to see whether a primer is necessary.
9

Step Nine

Practice with your new airbrush. Use scrap metal and plastic as target materials.
10

Step Ten

Remember, the key to getting an even finish is to start the airbrush to one side of the target area, spray with an even stroke across it and go past the area before releasing the trigger.
11

Step Eleven

Practice, using scrap materials, other applications such as thin lines and shading from one color to another.
12

Step Twelve

Use white artist's tape, drafting tape or automotive-quality flexible masking tape rather than over-the-counter masking tape, which may leave a residue when removed.
13

Step Thirteen

Avoid spraying at an angle or with excessive force along tape-masked border to keep paint from leaking under tape edge.
14

Step Fourteen

Clean your airbrush tip by spraying water, with a bit of liquid dishwashing soap added, through it after painting with acrylic paints.
15

Step Fifteen

Use common rubbing alcohol to finish the job as necessary.

Tips & Warnings

  • Practice, practice, practice. Like any creative skill, painting with an airbrush comes easily to those who practice most.
  • Water-based acrylics have become the paint of choice for modelers who use high-quality, major brands. Hobbyists can find premixed paint in authentic colors.
  • Some hobbyists prefer carbon dioxide or nitrogen gas reservoir tanks for a pressure source for airbrushes; however, inert-gas tanks must be refilled.
  • Wear a paint mask when using an airbrush. Safety goggles are useful as well.
  • Always use an airbrush in a well-ventilated area or in an open area.
  • Paint particles can overspray and damage other objects.
