Micro-Mark Air Airbrush Thinner, 20ml
Micro-Mark acrylics spray smoothly through an airbrush right out of the bottle, but for fine detail, thin coats, or high-flow applications, thinning is essential. Use the 20ml Airbrush Thinner to customize the flow and performance of your airbrush-ready paints.
- Designed specifically for thinning water-based acrylics for airbrushing
- Enhances atomization for smoother, more even spray patterns
- Maintains color vibrancy while improving flow and reducing tip dry
- Slows drying slightly to reduce clogging and overspray
- Made in the USA
Description
Micro-Mark Airbrush Thinner is formulated to work with our acrylic paint line and other water-based hobby paints. It ensures reliable spray performance, even through fine nozzles and at low PSI. This thinner improves atomization, reduces dry-tip buildup, and allows for smoother transitions, perfect for gradients, preshading, or modulation. Use it to adjust paint viscosity depending on the scale, surface, and detailing needs.
Micro-Mark Airbrush Thinner is included in these sets:
Item #29421 Essentials Acrylic Paint Set

How to Use Micro-Mark Airbrush Thinner
- Prepare Your Paint
• Pour paint into a separate mixing cup—never thin directly in the bottle.
• Add thinner gradually: Start with a 3:1 paint-to-thinner ratio (or adjust as needed).
• Mix thoroughly with a stir stick or pipette until smooth and lump-free. - Test Spray First
• Spray on a test surface to check consistency, spray pattern, and coverage.
• Adjust PSI (typically 15–25) and thinner ratio to suit your nozzle and effect. - Spray Your Model
• Use sweeping motions and build up in thin layers.
• The thinner helps eliminate spatter and clogs while improving fine control. - Clean Your Airbrush
• Rinse with water first, then flush with Airbrush Thinner or Micro-Mark Airbrush Cleaner.
• Disassemble and clean nozzle if buildup is visible.
Tips for Best Results
• Don’t exceed 1:1 ratio unless aiming for very transparent effects.
• Use with a gravity-feed or dual-action airbrush for maximum control.
• Shake thinner well before use.
• Store thinned paint only short-term to avoid pigment separation.
Micro-Mark Airbrush Thinner is also available in a larger 8 oz size.
