Back flushing an airbrush
Re: Back flushing an airbrush
I'm a bad boy and back flush my Iwata HP-C Plus all the time. Yeah, some paint gets pushed back beyond the air supply connection but it doesn't really affect the performance besides getting the needle temporarily stuck at times when it dries (not in operation). I also do all of my paint mixing in the cup, which is something I heard you should not do.

Ha Ha, seems to work!
Re: Back flushing an airbrush
I was having a similar problem, when I would get my airbrush out the needle would always be a bit stuck. I fixed that by not storing the needle in the air brush but instead in the box it came in between two pieces of foam.jkim wrote:I'm a bad boy and back flush my Iwata HP-C Plus all the time.

Hmm. My Iwata NEO I backflush. But now after reading these posts I may not anymore. Every now and then I get the same issues Lyle talked about. Kinda makes sense.

Re: Back flushing an airbrush
I have the same airbrush and I back flush as well. Never had a problem because of that. I do get the same needle stick because I don't clean it as well as I should.jkim wrote:I'm a bad boy and back flush my Iwata HP-C Plus all the time.

Re: Back flushing an airbrush
The only exception i backflush is while cleaning the airbrush with lacquer thinner.

Re: Back flushing an airbrush
I just caught up with this. This is interesting. I have a Badger 105, Sotar 20/20, and an Iwata Neo; all gravity feed that I always backflush with lacquer thinner when cleaning. I found that it cleans faster and more thoroughly; otherwise I have paint in the needle tube that blocks subsequent paint sessions. It usually only takes two backflushes and a couple spray-throughs of lacquer thinner and the brush is clean and ready to go for the next session. Doing this means I only have to break everything down once a month or so to do a thorough cleaning. I haven't gotten needle stick either.
John, I also mix my paint in the cup.

Re: Back flushing an airbrush
I guess I’m just hard on them. Just sent the 105 back to Badger, the HP-CS is dead and I have apparently lost another 105 that I put away so I would not loose it. The Badger 350 isn’t spraying right ...tip clog and spitting. Sigh. I think the 350’s problem may be paint thickness.
