Quick solutions to stay in the creative flow.
Whether you're a seasoned pro or a complete beginner, every hobbyist runs into airbrush issues sooner or later. This will help you diagnose and fix frequent issues, whether you're working with a GHAC-Swallowtail SD, GHPM-Mobius SP 0.3 & 0.5mm, or GHPM-Mobius 0.2mm. This guide breaks down the most common airbrush issues, what causes them, and how to get your gear back in top shape.
1. No Paint Coming Out
Symptoms:
- Air flows, but no paint sprays.
- The paint cup is full, but nothing’s happening.
Likely Causes & How to Fix it:
- Clogged nozzle: remove and soak in cleaner; clean with a soft brush.
- Needle misalignment or stuck: remove, inspect tip, reinsert gently.
- Too-thick paint: thin to skim-milk consistency (Gaahleri’s Kaleido Colorworks is a great no-thin option).
- Low air pressure: check PSI, 10–20 PSI for 0.2, 0.3 mm nozzles; 20–30 PSI for 0.5 mm.
2. Spitting, Sputtering, or Inconsistent Spray
Symptoms:
- Spray pattern is spotty or chaotic.
- Paint comes out in bursts.
Possible Causes & How to Fix it:
- Dried paint on the needle or nozzle: wipe the needle or nozzle, or backflush to dislodge stubborn clogs
- Loose nozzle cap or air leaks: tighten the nozzle head and air cap
- Inconsistent paint mix: stir thoroughly or use pre-thinned paint (pre-thinned paints like our Kaleido Colorworks prevent clogging mid-session)
3. Bubbling in the Paint Cup
Symptoms:
- Air bubbles rise through the paint.
- Paint either doesn't spray or does so weakly.
Possible Causes & Fixes:
- Damaged nozzle or O-ring: inspect; replace if worn (e.g, O-ring for GHAD-39, GHPM-65, GHAC-98D etc. all spare parts available)
- Improperly seated needle: Reinsert the needle gently, ensuring it seats properly.
4. Trigger Feels Sticky or Won’t Move Smoothly
Symptoms:
- The trigger is hard to press or feels stuck.
- Air or paint flow is delayed.
Possible Causes and How to Fix Them:
- Dried paint in the internal mechanism: Disassemble and clean around the trigger assembly and internal channels.
- Lack of lubrication: Apply a tiny amount of airbrush-specific lubricant (never household oil)
Tip: Be gentle when reassembling — overtightening can cause more resistance.

Model-specific Tips
- GHAD-39: With 0.35 and 0.5 mm calibration and easy-clean cups, it’s user-friendly—use its cutaway handle to balance weight
- GHPM-Mobius SP 0.3 & 0.5mm (siphon): Low-PSI, high-volume system—keep siphon cup and seals clean to prevent air leaks.
- GHAC-Swallowtail SD (side feed): Offers better visibility and a comfortable grip—after use, clean the side cup and joints to avoid clogs.
- GHPM-Mobius TG 0.5mm (trigger): Dual caps demand switch-cleaning after switching caps. The trigger requires light lubrication for a smooth feel.
