I have a problem with my airbrush. I recently got the whole set of Vallejo Game Color and I have a problem with a few colors.

The Goblin Green and Moon Yellow spray out very wet, I get spidering and wet paint on the model instead of what I am used to.

There isn't water in the line, I have two water traps set up (one at the compressor, and the second connected to the first with 15' of hose.)

Other colors are working fine (I sprayed out some Gray and it worked fine.) It just appears to be a few colors.

I have tried spraying from 15psi all the way up to 40 and there is no difference.

Is there a way to thicken the paints? What do I need to do on this?

Vallejo make both a Game Color and a Game Air. As you haven't mentioned the need to thin the paint, I'm assuming here it's the Game Air line you got?

I've found the 'Air' colours that Vallejo do can vary in consistency a bit, though I've never had problems with any coming out much too wet. It sounds like maybe there's been some separation going on in the bottle and it might not be properly mixed or something.

If you haven't tried it already, it may be worth popping an agitator in the bottle and giving it a really good shake, or trying to get a cocktail stick or some other implement in the bottle and giving it a good mix (the tip of the bottle will just pull out for you to be able to get in there).

I've never had to thicken a paint up, so if they are genuinely really watery, I don't know what else to suggest.


If on the off chance you are talking about Game Color and you are thinning them, then the suggestion here would be to add less thinner and see how you get on.

Let us know how it goes!

If you're getting spider webs it's probably a combination of the paint being too thin and you're too close to what you're trying to paint.

If you're adding thinner to the paint, just add less. If you're putting undiluted paint directly into your airbrush and it's still too thin, back away from the model.

I've never had a Game Color so thin that I could spray it undiluted through an airbrush, so I find that rather odd. Are you sure pigment hasn't settled on the bottom of the bottle? You may need to give it a stir as just shaking may not be enough to get it mixed properly.

Yeah, it is the game air.

I will try adding an agitator. I completely forgot I had to do that on my Valejo Surface Primers. Hopefully that will sort this issue out.

Well, Vallejo yellows and greens tend to be pretty thin.

There is a good chance that it's probably well mixed and that what is happening is the result of user error. Just back the airbrush away from the model, spray thin layers, always keep it moving to prevent it from pooling.
