Hello all

I have an aztek 430 airbrush and just this morning it began to spit a bit. It didn't flow as freely as earlier use. I turned the pressure up a little and it was not as bad.... but could this be a sign of the paint not being mixed enough?

Any advice would be great.

thanks

Also, may want to try and clean the nozzle. I remove mine and soak it in cleaner. I also keep a toothbrush near and every now and then,scrub the front of the nozzle.

Hi Hasty P

Was it spitting paint or water?

Spitting paint probably means the the tip is clogging. In a long session, paint can dry on the tip - try cleaning it with a brush-load of thinners. Spray away from the model and when it clears and sprays normally, carry on with your paint job.

If it's really gunged up, strip the airbrush down and soak the tip etc in thinners.

If it was spitting water, you need a moisture trap. Even with one (or two, in my case!) you may still get occasional spatters of condensation in very damp or humid weather.

Hope this helps

Hi Hasty P
You may also want to be sure that your paint is not too thick. This may also cause the problem you are describing.

hasty,

one more thing to check on, check the nipple of the tip to assure that there is no damage.

I was checking mine yesterday as my Iwata was doing the same thing. Thought I had cleaned it sufficiently, but discovered that the nipple (a $24 item at Dixie Art) was damaged. The nick will cause the same sputtering problem.
