GDille Posted June 4, 2010 Report Share Posted June 4, 2010 Hey Folks, I bought an airbrush for power paint from tj's and juat haven't been able to get the powder to come out consistently. Ive got several more deals working out with filling stations and farmer's markets and this would make it a million time more efficient and easy. Ive tried shaking the powder, low air, high air, middle air, and nothing. Is moisture a possible culprit? Any help is Awesome George Quote Link to comment Share on other sites More sharing options...
reeves Posted June 4, 2010 Report Share Posted June 4, 2010 George, I have had the same problem. The thing will spray a bit and then seem to clog up. My cure has been to shake the powder in the jar and it will start working again. I have also found that you have to have at least 3/4 of the jar filled with powder and it will spray more consistent. I don't think it is a moisture problem but more a problem of they are pushing the limit on what can be sprayed through such a small orifice. Nature of the beast more or less. Also, it doesn't take but a few pounds of pressure to make it work, any more and you can get out the vacuum cause it is going to be everywhere. If you are trying to increase your output for the sake of production, you may want to investigate electrostatic equipment. Hope this was of help to you.

smalljaw Posted June 5, 2010 Report Share Posted June 5, 2010 Check your powder, it will sometimes clump up just from moisture in the air and when you begin to spray the clump will block the pick up tube and then you get the problem you described. To fix this and make it work better is easy, first the jar, what ever your powder is in make sure it is only filled up to the point that the pick up tube is less than half covered, this allows you to shake and move paint every time you stop or just before you start. The other thing that will help is trimming the tube if you are spraying out of the jars the paint comes in, I have a tube that is short for full jars of paint and a longer tube when the jar is getting empty.

toadfrog Posted June 8, 2010 Report Share Posted June 8, 2010 I use a fine screen wire to sift paint especially with some I have had for a while .Ive been able to pick out undesireable bits that way. the mesh is hard to find Its almost like panty hose in hole demention.

psilvers Posted June 24, 2010 Report Share Posted June 24, 2010 I was thinking of getting one of those guns. How does it work? Did those suggestions clear up your problems? Pete Quote Link to comment Share on other sites More sharing options...
Beto Posted June 25, 2010 Report Share Posted June 25, 2010 Hi all This is the first time I post/reply to something in this website. Thanks to all for your magnificent work. I get involved with industrial powder painting through my work and the way I've seen it done is by having the powder in suspension inside the containers. In other words the powder is not just sitting in the jar/container, there is a jet of air constantly blowing over it and keeping in it agitated, also in the industrial process the aspiration is not from the bottom of the container but from the top, maybe removing the tube in your air brush and adding some air to the jar could do the job. greetings from oz Beto Quote Link to comment Share on other sites More sharing options...
