Hi guys

I am after some help for a spray gun noob please. I am spraying a Pow Wow using a spray gun for the first time. My only training has been watching some YouTube videos that seem to be reasonably informative.

The problem is that the primer has gone on dry and powdery.

I am using a Blackridge Touch-up spray gun with a 0.5mm nozzle, http://www.supercheapauto.com.au/Product/Blackridge-Air-Spray-Gun-Touch-Up-100mL/340075

I am spraying Septone Primer Surfacer thinned 60:40 (thinner:primer) as per manufacturers instruction with acrylic lacquer thinners http://www.supercheapauto.com.au/Product/Septone-Primer-Surfacer-Grey-Acrylic-1-Litre/1408?menuFrom=1021683

I started off using 45 to 50 psi.  When it came out dry and powdery the first time, the information I found suggested that the air pressure was too high.

I sanded it back with 400 wet and dry and started again.

I bought a little digital regulator and attached it to the gun. I experimented with the air pressure, starting at 35 psi and trying 32 and 37 psi. All seemed about the same.

It still came out dry and powdery but this time, when I sprayed what I thought was too close to the job, I got some areas of good coverage.   

I am a complete spray gun newbie. Any advice would be gratefully received.

Many thanks

Trevor

Yea, I was thinking dial up the material and reduce the air.

Thanks for the advice, Ty, Mike, and Randy. I'll try those tips this weekend.
