Looking for some help

[jeffhogrider]

I just joined this forum and took up airbrushing not too long ago and am looking for some help. I am using Autoair Colors to airbrush with, but I get a lot of water or wet spray that splatters on my canvas. I've tried adding reducer thinking it was too thick, but that didn't help, as well as adjusting the air pressure. I'm using 40psi and an Iwata airbrush. Any help would be appreciated.

do you have a moisture trap on your compressor ? cuase thats 1 problem ive never had with using AA's .

Sounds to my like your getting paint build up on the tip.
Can you be more specific.
Are you spraying ok ? then splat.
Is it splutering paint all the time ?

You will find plenty of people willing to help here.

Ohh and welcom to der forum.

I've got a moisture trap on my compresser and I tried emptying it and that helped a little, but still not completely. I've even put some airbrush lube on the tip of the needle, but the problems still existed. I find that it usually starts sputtering after i've been airbrushing for a while and then it seems it just won't stop sputtering.

The moisture trap is to close to the compressor and the air doesn't have enough time to cool and codense the water out. Put 25 feet of air house on then the moisture trap mounted on the work bench or easle. Its also a good idea to have a regulator mounted near by for easy adjustment also. Just keep the regulator on the comp turned up and adjust at the bench.

in addition to adding more hose you could put some of that hose in a bucket of cold water to cool the air down before it gets to the trap

Very true ... just make sure the temps are above 32 degrees F.

I use AA paint and often have what may be the same problem. I am not up to giving a lot of advice due to being in the learning process myself.

Don't misunderstand, this may not be your problem, but most of my trouble with this is controlling the paint coming out of the airbrush. Often when I start spraying I open the valve to much and there it is. Paper towel and water, start over. I believe I first heard this described as spiders. What ever they are I am slowly getting rid of them. Takes time and practice.

I am posting this because you say you are new to this too, maybe you are past that.

Sorry, forgot to say welcome to the forum.

Hi Jeff, welcome to the forum. As Clem pointed out, it might be that, but there are a bunch of things that can cause it. Over reducing, air pressure too high, air pressure too low, etc., of course it could be what the other guys are saying, water in the line.

Try that first, but check your reduction on the paint, if any, then try at 29 psi, and see if it is still there. Watch for tip dry, pick the tip and see how it goes. Keep us posted!

Hi Jeff,
Welcome from Washington state!

I'd suggest that you blow out your entire line for a couple minutes without the airbrush attached.
Moisture can/does build up in your line and the only real way to get rid of it, is a good open line blasting.
Run it until the line is dry.
Then, re-attach your airbrush and spray into a paper towel.
This should solve your problem.
If you're using a long air hose before your airbrush line, you should use a shorter one if possible.

I use Auto Air and have never had that problem from the paint itself, however, make sure that you're shaking the paint well and straining it before using.
I cut small rounds of paint filter material (you know, they've got those cheap paper funnel filters at hardware stores...just tear out the filter part and cut the small rounds to fit into your paint cap. I leave them there and change them every few months.
