2. Product Overview

  • Paint Type: Acrylic, Water-based
  • Finish: Matte
  • Volume: 17 Milliliters
  • Application: Primarily airbrush, suitable for brush application.

3. Setup

3.1 Preparation of Paint

  1. Shake Well: Before each use, shake the paint bottle vigorously for at least 30 seconds to ensure pigments are thoroughly mixed. A mixing ball inside the bottle assists this process.
  2. Thinning: Model Air paints are pre-thinned for airbrush use. For most applications, no additional thinning is required. If thinning is desired for specific effects or very fine lines, use Vallejo Airbrush Thinner (71.261) sparingly. Do not use water as a thinner for airbrushing, as it can break down the paint's binder.

3.2 Airbrush Setup

  • Air Pressure: Recommended air pressure for Model Air paints is typically between 15-20 PSI (1.0-1.4 bar). Adjust as needed based on your airbrush model and desired spray pattern.
  • Nozzle Size: Model Air performs well with nozzle sizes from 0.2mm upwards.
  • Ventilation: Always work in a well-ventilated area or use a spray booth with proper filtration.

4. Operating (Application)

4.1 Airbrush Application

  1. Surface Preparation: Ensure the model surface is clean, dry, and free of dust, grease, or mold release agents. A primer is recommended for optimal adhesion and color vibrancy.
  2. Loading Paint: Use the dropper bottle to directly load the desired amount of paint into your airbrush cup.
  3. Spraying Technique: Apply paint in thin, even coats. Allow each coat to dry to the touch before applying the next. Multiple thin coats will provide a smoother finish and better coverage than one thick coat.
  4. Drying Time: Model Air paints dry quickly to the touch, typically within minutes. Full cure time may take several hours.

4.2 Brush Application

While primarily designed for airbrush, Model Air paints can also be applied with a brush for small details or touch-ups. For brush application, a small amount of Vallejo Flow Improver (71.262) can be added to improve brushability and reduce brush marks.

5. Maintenance

5.1 Airbrush Cleaning

Clean your airbrush immediately after each painting session to prevent paint from drying and clogging. Use Vallejo Airbrush Cleaner (71.099) or a suitable acrylic cleaner. Flush the airbrush thoroughly until no paint residue is visible.

5.2 Paint Storage

Store paint bottles upright in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the dropper cap is tightly sealed to prevent paint from drying out.

6. Troubleshooting

  • Airbrush Clogging:
    • Ensure paint is thoroughly shaken.
    • Check air pressure; increase slightly if too low.
    • Clean airbrush nozzle and needle thoroughly.
    • Consider adding a drop of Vallejo Flow Improver.
  • Poor Coverage/Transparency:
    • Apply more thin coats instead of one thick coat.
    • Ensure proper surface priming.
    • Check paint consistency; it might be over-thinned.
  • "Spidering" or Uneven Spray:
    • Reduce air pressure.
    • Move the airbrush closer to the surface.
    • Ensure paint is not too thick.
