Airbrush problems

[Runway]

My airbrush was good and clean but when i did my priming. I am seeing little blotches. And what to be little hairs. Useing Valero primer. But it did not say to thin. Should i be thining all primers even when they say not necessary?

Did you mix it really well ? - Stir not shake only ?

 

[Runway]

It says to shake well

 

[urumomo]

Open it up and make sure it's uniform

 

[Runway]

Just shake thats all i did just like some of the videos that i saw.

 

[Runway]

Should primers be thined?

 

[urumomo]

so we're not going to check ?

What kind of primer is it ? Acrylic or polyurethane ?

 

[Runway]

I think i have some very light sanding to do?

 

[Runway]

Acrylic

Wnen i test my flow rate on a peace of work i don't see any of that. That showed up on tne model.

What tip size and air pressure and how far are you from the work ?

It's OK to thin any coating for AB work since environments differ . Just use the smallest amount necessary .

 

[Runway]

40 psi drops to 20 5mm needle

 

[Runway]

About 6"

 

[urumomo]

" 40 drops to 20 "
?

 

[Runway]

40 psi meter reads drop to 20 psi druring spray.

 

[Runway]

6" away from work.

 

[Runway]

What do you think i am doing wrong?

 

[urumomo]

Can you post a pic of the problem ?
I'm confused why you're not having the issue on your test piece .

 

[Runway]

I will try.

 

[urumomo]

sorry , got stuck on a phone call .

Try spraying closer to the work ,
maybe at 25 psi
