Gents, and Ladies.
I started airbrushing again after 20 years. Any ideas on air pressure and paints? I am struggling with spit splash and air pressure.

Which airbrush did you end up going with?

Start at around 30psi and dial down from there. My sweet spot is 20 to 25psi, but that may well be different from yours.

I read your blog posting and the first thing I would do is swap out your compressor with one that has a pressure gauge on it so you can adjust the air flow. I typically paint in the range of 8-12 PSI, maybe up to 15 PSI for some of the primers which are a bit thicker.

I tend to use paints specifically designed for the airbrush now. Vallejo has an Airbrush line as does Ammo by Mig, AK Interactive and Badger. It just saves a little time thinning paints. Otherwise you can shoot just about any paint through an airbush if you thin it down properly.

I lean towards water or actual airbrush thinners as opposed to isopropyl alcohol or windex. The ammonia in windex will break down the seals in an airbrush overtime and vaporized isopropyl alcohol is quite bad for you to breath.

Use a respirator style mask for closed in spaces or paint where there is a lot of ventilation.

I use Badger airbrushes and note that if a company has their own airbrush it was most likely designed by Badger. It's a tool get the best you can afford.

Thanks for the comments guys. I am using a Paache H still. The air compressor is adjustable, but I think because I am using the lower in of its range when I let the air our the PSI drops too low to maintain it. That said, I have been at about 10-15 PSI. I'll try the 25 PSI and see what happens. When I have cranked it up, the paint is blown out too fast.

I did order a kit with another airbrush and a smaller airbrush compressor. The airbrush is more like the Badger. I hope to have that next week.

I'm with Heisler. Since upgrading my compressor to one with a built in water trap and adjustable compression, my output has improved all round.

I got my compressor yesterday and I hope to have it up and running this weekend. I will keep you posted!

I typically spray between 15 and 20 psi. Buy tamiya paint and a double action gravity feed airbrush. "Thin your paint 1 part paint to 1 part isopropyl alcohol.

Thank you for the tip!
