Solutions:
- Clean and soak the nozzle to unblock it.
- Thin your paint with a suitable reducer and then try spraying.
- Check if the needle-chucking nut is loose and tighten it.
- If the issue is the pressure, try increasing it, it might be too low to atomize the paint.

What PSI should I use for airbrushing?
COMPRESSORS - A unit that generates at least 30 PSI is recommended to start airbrushing. Some applications, such as T- shirt painting or other fabric painting, may be more efficiently done at higher pressures (up to 65 psi).
How thin should paint be for airbrush?
For airbrush applications, the suggested thinner-to-paint ratio is 1:4, although you may need to experiment a little to achieve the effect you want. This paint thinner is ideal for model air and liquid acrylic paints, although it has been found to work with a variety of other mediums as well.

When the paint makes a splat, it's called spidering. It happens when the paint is too thin, the pressure too high, or you are too close. It just doesn't spray like it use to. Two parts that are very critical to the way an airbrush sprays are the nozzle, or tip, and the needle.
How to fix airbrush spraying blob?
Solution: Unscrew the needle-locking nut and then lightly push the needle forward till it is inside the nozzle. After that, tighten the needle-locking nut. It cases where the airbrush sprays just a blob of paint when the trigger is depressed.
Why is my paint nozzle not working?
The most often cause for this problem is a blocked nozzle, but it can also be thick paint, a loose needle chucking nut as well as low or inadequate air pressure.

How to clean a needle that is damaged?
If the needle is damaged, just remove it and clean it using a cloth dampened with airbrush cleaner.
Why does my paint have bubbles?
Bubbles appear in the gravity cup or suction bottle. Clearly, this means that air pressure has entered the paint reservoir. This could occur due to an air leak in the nozzle area/air cap or due to tip dry/blocked nozzle, a loose air cap/head or even a split airbrush nozzle.
What to do if compressor is improperly mounted?
If the compressor is improperly mounted, refasten the bolts and check if the vibration pads need to be replaced or installed.

How to vacuum paint out of airbrush?
In order to create a vacuum to pull paint out of the brush, the nozzle has to protrude just a tiny bit past the front of the spray regulator. If it doesn't, you can get pressure instead of a vacuum here and air will blow back into the cup or bottle. This can be a problem in airbrushes with rubber O-rings in the head assembly.
How to fix a paint nozzle?
Sometimes, it can be fixed by rotating the needle in the nozzle with slight pressure. Some people apply a little pressure to the back of the needle when they tighten the needle chuck. But, you have to be careful not to damage the nozzle. Soaking the nozzle in a solvent that dissolves dry paint may also help.
Why does paint spray when you press the trigger?
This happens because of an imperfect seal between the needle and nozzle. It sometimes doesn't show up at lower air pressures. It can be caused by a small particle of dirt or dried paint in the nozzle, or a needle or nozzle that is not perfectly round. At low pressure, there is not enough vacuum to overcome the paint viscosity and pull it through the small opening. When the pressure is increased, so does the vacuum and paint is expelled.
How to stop paint from flowing in siphon bottle?
