How to Use an Airbrush

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.

Difficulty: Moderate

Instructions

Things You'll Need:

• Airbrush Head Sets
• Airbrush Jars And Covers
• Airbrush Moisture Traps
• Airbrush Propel Regulators
• Drafting Tapes
• Extractor Fans
• Face Mask For Painting
• Basic Spray Gun Sets
• Latex Gloves
• Rubbing Alcohol
• Rubbing Alcohol
• Airbrush Cleaners
• Airbrush Compressors
• Airbrush Kits
• Airbrush Paints
• Bath Exhaust Fans
• Respiratory Protection
• Safety Goggles
• Wet And Dry Sandpaper
• Safety Goggles

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

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

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

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

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

8. Check to see whether a primer is necessary.

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

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

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

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

15. 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.

on 9/6/2008 is it possible to use acrylic lacquer paint rather than one the modellers commonly use for painting?

on 11/22/2005 I've found the new Press and Seal Glad Wrap is handy for masking off large areas very quickly and efficiently, blocking over-spray and making painting a breeze!

on 11/22/2005 Never spray alcohol out of an airbrush for any reason. It can easily cause brain damage and can cause a flash fire with the slightest spark.

on 11/22/2005 Make sure to cover up every part of the material that you aren't airbrushing. The time it takes to cover it is worth it. If you even cover most of what you don't want airbrushed, the parts that aren't covered will still get paint on them. The paint travels far! Try to cover everything that's five feet or less from your painting area (or areas). Also, if you absolutely have to paint outside, remember that the paint will travel even farther, so cover more! I've had this problem many times and it is very frustrating, especially when it isn't easy to fix.

on 11/22/2005 Use camera film containers, the ones that the new 35mm film comes in. You can get it from your photo shop for free, they throw the old ones away. If it is stored for a long time, put it all together (labeled of course) in a Tupperware container in the refrigerator (that is, if your mom or boss will allow it).
