Splattering
Posted by lizardqing on Sunday, November 9, 2003 7:19 PM
I have a problem all of sudden that I can't figure why it is happening. My airbrush is very splotchy when it sprays and does not produce a very good paint job. I have cleaned the tips and the inside of the brush the best I can. It's not doing it with only one paint but any that I use. Anyone have any ideas?

First of all what airbrush is it ?
If it is a Paasche VL then it is possible that the head is leaking air which can cause this.

Yea I guess that would help huh? It's an Aztec 4709. I already know what some are going say , but it's my first airbrush and I got a real good deal on it.

lizardqing2,

I had the same problem. How I fixed it was to replace the needle. I take great care in cleaning my Badger airbrush every use. I didn't even think that the needle needed to be replaced but after doing everything else and cleaning my brush a couple of times with no improvement I said that it had to be the needle.

After the needle was replaced my painting results were intermittent noticeable

I had this problem when I started airbrushing. For me the soulution was simple... thinner paint and less air. My paint wasn't thin enough and was drying on the needle this was causing clogs and spatters. By lowering the air pressure 12-18 lbs and making sure my paint was at least 25% thinned I eliminated the spattering.

Thanks for the ideas. I'll try thinning it more and see how that does. Anybody know how to change the needle on an Aztec? I've never done that before, I have'nt really had the airbrush that long and have maybe done 3 or 4 models with it.

The way to change the needle is to just waste your money replacing the entire nozzle. That's the way the Aztek system works.
Despite what the manufacturer claims, the only way to get the nozzle/needle assemblies clean is to disassemble them. If you haven't been doing that then that's probably where your problems are stemming from, although I've also heard that disassembling them compromises their integrity. This, in my opinion, is why the Aztek is such a P.O.S.

Too much pressure and close spray distance may produce this effect, with no fault to the airbrush.

Well I tried running the little plastic wrench tool around inside it and there seemed to be some slight cakeing up in it. I then tried spraying and it seemed to work fine again. i think I also may have thinned the paint more than I normally do to. Thanks for the help , hopefully it works fine for a while now.

Liz-don't be afraid to take your airbrush apart-it's the only way to really clean it. Check for air flow in the tip and that teflon gasket (if your aztek has one). Also make sure the needle is clean and not bent (paint will accumulate and then spit with a bent needle). If you have a detachable paint cup check for good flow. When you reassemble-get a snug fit.
