Zero White Primer "Pebbling"
Posted by mightypudge on Saturday, October 9, 2021 3:39 PM

Howdy!

I usually use Mr. Surfacer 1500 grey primer, which always leaves a very smooth surface. However, on my current model I wanted to use white primer as the base color is going to be very light. The only white primer I had on hand was Zero White Primer, which I had never actually used before. 

I did notice the stuff is pretty thick, but is supposed to be airbrush-ready. I had to shoot at 30-40 psi and I stayed about 2 - 3" from the model. After several coats, the surface has a pebbled look and feel, not at all paint-ready.

So, did I shoot too dry, too thick, etc.? Or, is this just how this stuff works and I should be ready to wet sand it?

I have a couple Zero paints but havent used them.  I'd guess make sure to fully mix/shake the paint.  Maybe try thinning and a lower PSI - 20 or so and shoot it on a test piece.

Thanks,

John

Did you thin it?  If you're seeing that its thick, I definitely wouldn't call that airbrush-ready.  No matter what paint or primer I'm shooting, I thin it enough to make it run down the side of my mixing cup like 1% milk would.  I rarely have to go above about 20 PSI, and sometimes go as low as 10 when painting the insides of tubular parts, even with primer.  I'm thinking that your white primer must have had some of its contents evaporate for whatever reason, or maybe that batch was no good to begin with.  

I also like to use sticky notes when starting my airbrush to make sure I have the right pattern width and smooth paint flow.  Makes it really easy to see if your paint is splattering due to being too thick.
