Airbrush spitting water out.

Tools, Techniques, and Reference Materials Painting and airbrushing

hey guys,
been awhile since I had a question for you guys, but i have got one now.

When I am spraying, after a little bit (couple minutes) my airbrush starts to spit water out and ruins my finish. The thing that is really getting me is that I have a water trap on my compressor. So, do I have to empty the water trap out or something? Its been raining alot over here so if thats a problem…
also, when it spurts out water I just unscrew my airbrush from the hose and I let the air run for a little bit and water forms on the tip of the hose.

so, do any of you guys know whats going on?[B)]
thanks

You do have to empty the water trap out from time to time. The closer to your brush that the water trap is, the better for that matter. If it’s been raining a lot lately though, and the water wasn’t a problem before recently, emptying the trap should take care of your problem. We’ve had issues with water in our traps at work lately too, it’s been raining a lot here as well.

At most places I’ve worked, we drained the air system weekly and I drain my system here at home at least once a month (or more if the weather has been bad - rain or high humidity). If you are using a compressor with a tank, you need to drain the airtank at the same time.

You can also purchase a moisture trap for your airbrush hose. They can be a life saver.

Hey
I have the same problem when I spray, so I asked [Paul Boyer] he suggested that it was to do with the moisture trap even though I have one on my compressor he said that it works best when it is futher down the line.

In the winter my basement is dry with the heat going, so moisture isn’t a problem. In the Summer I keep my hobby room dehumidified (with a dehumidifier of course), and open windows when I need ventillation. Perhaps air conditioning would also dehumidify a room?
Still, you should empty moisture trap every once in awhile.

I don’t have that problem in winter cause the heat is on and the house is as dry as a popcorn F@#t. But in the summer the humidity is a killer so I have a water trap on my regulator and one on my line just below the brush. I found I had to do both to keep the water out even when I would empty the one on the reg. in the summer.
