How to Lay in Colors When Airbrushing

Model tanks display several subtly distinct layers of paint.

"Laying in" colors in an airbrush project usually means applying different colors to the same model, typically on top of one another. The object is to blend colors so that the layers are distinct but look cohesive. Working in thin layers, beginning with the dominant color of the subject, gives the best results. Begin with the lightest color because dark colors sometimes show through too much. The technique effectively works with figures and military subjects such as camouflaged tanks and planes.

Things You'll Need

• Airbrush
• Compressor or other air supply
• Airbrush-ready paints
• Airbrush cleaning fluid
• Transparent paints
• Sealant

Instructions

1. Set the airbrush pressure for about 15 pounds per square inch.

2. Load a few drops of the dominant color of the model into the airbrush reservoir.

3. Select the lightest color in your color scheme for the first layer.

4. Hold the airbrush six to eight inches from the model and apply the color in smooth, even strokes from one side to the other with light pressure on the trigger to lay in the base coat. Allow it to dry, which should take a few minutes.

5. Spray out any remaining paint and fill the reservoir with cleaning fluid.

6. Spray out the cleaning fluid until the airbrush is completely clean.

7. Add a new color and repeat the process.

8. Add layers of transparent or semitransparent paint in the same manner to add depth to the color.

9. Seal the kit with an aerosol sealant.

Tips & Warnings

• Use a small amount of paint in the airbrush for each coat to avoid waste. Use cardboard or old model parts to experiment on. Different levels of humidity, air pressure or elevation might require adjustments in air pressure from the compressor or air tank. An oil wash of 95 percent paint thinner and 5 percent dark oil paint can be applied after the sealant to further unify the paint job.

• Always airbrush in a well ventilated area. Do not use acrylics and enamels or lacquers in the same airbrush.
