Airbrush clogging

Recommended Posts

Hey Reaper-forum-brain,

 

I have had an airbrush for a good year now. I have learned quite a bit about it, but lately I have a problem. I have read articles and watched all the videos about airbrush care, etc. But my nozzle seems to be clogging. Here are the symptoms:

 

- Without a nozzle (but with needle) it works fine. It blows well and hard. So this is why I am ruling out the airfeed or the compressor. I have gone from 15-30 PSI to see if that mattered any.

- I have cleaned all the bits of my airbrush with my ultrasonic cleaner. They should all be clear, the only thing that is hard to see is the nozzle. And I mean the nozle not the nozzle cap.

- So if i attach my nozzle to the airbrush it already sprays less air, which makes sense with the small hole

- If I use water... thinner, or other stuff I spray... ok...

- If I add paint, bam it goes to a small line and then just nothing. And I do thin it using more then 50% Vallejo Airbrush Thinner. I have also tried it without thinning, etc. I have had this work in the past.

- There is no visible paint on the needle.

- The needle/nozzle I am using is 0.5 and 0.4. They do the same thing.

 

I just keep cleaning, getting stuck again, and getting really annoying. Any ideas? It is a Evolution, see picture.

I've got the Evolution as well, and I think I understand your problem, though it is hard to fix the problem from afar.

 

It could be that there's something stuck inside the nozzle. What I normally do when I encounter problems like this is: I use a brush cleaner (like paint thinner, but far stronger) and an old needle to "clean" the nozzle from inside (because the needle is the only thing that runs through the nozzle to the end) If you have got a cleaning needle, that's even better. If you use the needle, a cleaning fluid and a paper towel, which you put in front of the nozzle (so it sucks up the moisture) you should be able to unclog the nozzle.

 

I hope it makes sense - it's a bit hard to explain such specific terms in English.

It is good.  I typically pour excess paint out and then shoot several cups of water through my brush.  Only after the brush is "painting" clear water, do I use cleaner.

 

I'm gonna try the method in the video.

I think I did as the video said (Thanks for the link btw). I guess I will go over it a few times. The backblasting is tricky. First sleep, then afterwards, more cleaning.

I get the idea the problem might be in the nozzle being dirty or something. I can't seem to keep being able to see from one end of it through to the other. I can unplug it temporarily, but I think it clogs semi immediately again. Implying some sort of dirt. I am thinking it might be that I have used inks a few times over the past month?

 

Regardless I left it in airbrush cleaner, but no dice. Any pro tips as to how to heavily clean a nozzle for the evolution?

 

These things are like... 5mm wide? And look roughly like this:

If the narrowest point is at least 0.5mm you may want to look at some interdental brushes. 

The Pink ones from Tepe is listed as 0.4mm stem...

Well I can push a needle through, that is  not the point but I can't seem to actuyally remove any of the paint/ink that I suspect is in there. :/

There are specialist wire brushes available to ream out the nozzles. It might sound like what you need as your other methods are not working. 

 

Might it also be the needle itself? is your needle tip straight? Sometimes, if the needle tip is bent, it can act as a plug. Remember that paint is thicker than water and needs a larger opening to get through,

Having read all of the above, I think:

 

1.  You might have a bent/deformed needle, a ding in your nozzle cap, or a deformed nozzle.  Or a combination.

 

2.  But, most probably, your paint/thinner/water mix is off, causing clogging.

 

3.  If you've thoroughly cleaned your brush and you're getting no paint coming off as you clean, then the brush is clean.  You just have to know what a clean brush looks like.  Here's some info; some of this stuff is nasty -- as in, to your health:

In particular:

 

I soak airbrush nozzle tips in acetone when they get gummed up with paint.

 

4.  So, look at 1 (I replaced parts several times as I learned to airbrush), and replace the parts.  Then you'll know that 1 cannot be the issue.  If you still have the issue, it is your mixture.
