Greetings,

Stupid question: Just got the airbrush from duracoat with my duracoat bottle of paint. I plan to plug that airbrush on my bostitch air compressor. What pressure do I set it up?

Thank you

15-25 psi should be about right but you should have a recommendation by the manufacturer included with the airbrush.

Nope. No recommendation at att that I was able to see. Maybe I overlooked it. But it came with no other instructions than what is on the back of the package...

Thank you

Since there are no manufacturer recommendation, I suggest starting with a practice piece. Begin at 15psi and check spray and pattern. If coverage is acceptable, stop there if not, gradually increase operating pressure in 5psi increments until desired pattern and coverage is achieved. ALWAYS start low and work up. Good luck!

The Paasche instruction book says 10-20 psi for most airbrush colors, so I would say jimmyraythomason's advice is spot on.

If you're going to be doing a lot of Duracoating, you'll want to invest in an automotive touch-up type of airbrush.

Do not forget to use some drier filter in-line to trap any moisture from the compressor. This will ruin your day if even a tiny drop of water gets through...

I do I do that????

You can buy an inexpensive in-line air filter.
When you run a compressor it compresses the air and you'll often get a slug of water compressed with the air.
This sprays onto the work, ruining it.

You can buy a filter from most hobby shops. It's usually an aluminum tube with an air hose fitting on each end and a drain screw:

GREAT site for airbrush info!

Greetings,

I want to keep you posted:

Yesterday I attached the airbrush provided by duracoat on my Bostitch compressor. Before I did this, I filled up the tank, open the valve at the bootm and canted it and let the air get out while it was working to get out the maximum of water. I closed the valve and proceeded to paint the gun.

It took like forever before the paint went out and I had to setup the pressure to 40 pounds, not 15-25 pounds as suggested by some of you guys and suggested by duracoat(I wrote to the guy and he asnwered back)

I had tu turn the paint output screw like 50 times on the left (it makes more paint to get out) before the paint went out. Even then, there was very little paint going out.

Anyway, after 40 minutes of spraying, the gun is astounding! I guess the fact to have such few paint going out made me applying the paint more slowly and it was a perfect job.

I am now getting ready to paint 2 more. :)

Thank you
