Watery Paint

I'd say you probably mixed it too thin.

Many of the Tamiya Acrylics I will use straight from the bottle with no thinning.

How much pressure were you using on your airbrush? Thin paint will always seem watery with a lot of pressure behind it.

I use Tamiya acrylics and I thin them 3:1 with 91% isopropyl alcohol then spray at about 15 psi.

The other problem could be that you are spraying too much, or not getting any motion with your spraying so you accumulated too much paint on the model.

I'm with Shermanfreak on this one, I love Tamiya acrylics, but their viscosity varies. Flat black goes straight through, but say Dunkelgelb needs thinning, even during the spray. Also make sure you have a moisture trap, you could be adding water through your airsupply even if you aren't getting those big waterbombs.

I usually thin Tamiya acrylics with enough water to get a milky consistency and this works fine for me.
The only colours that don't mix well with water are white, yellow and red.
Should I only use the Tamiya thinner for these colours or is there a particular ratio that I have to mix them with?
What would happen if I mixed future floor polish and tamiya paint and passed it through the airbrush. Would this have a bad effect on the airbrush?

Thanks

I usually use 90% isopropyl alcohol with Tamiya paints. I read here that using alky will always cause it to give a flat surface, and I always do get a flat surface so that is probably true.

Using the recommended thinner is always the best way to go. PolyScale recommends using water to thin their paints, Tamiya and Model Master recommend using their brand.

It would probably spray, and probably wouldn't hurt the airbrush, but I can't think of any reason to do that.

did you stir well? i thin tamiya acrylics sometimes by 70% thinner to 30% paint when weathering and such. ive never had that kind of problem with tamiya. later.
