My flat black looks weird..

Cant figure out this problem...i airbrushed the paint at 20psi and the paint came out like s**t...the paint has been thinned

[Lambo003]

Looks like moisture got in your air line, but it could be mold release agents not being washed off completely and it's reacting with the paint.

Are you using a can of compressed air or a compressor? Try adding a moisture trap if you don't already have one . . .

The other thing that can cause an effect like this is if it's too cold.

...or thinned too much/not stirred well enough

[ShOrtyOC714]

To me, looks like you thinned out the paint too much, and when u sprayed it came out watery and just dried with streaks. When i air brush i only put a little bit of thinner into the paint, i only put about 10 or less drops.

Looks to me like the paint is not "even" and to heavy in places.
Do 3-4 light mist coats

this happended to me before, in the summer (so it wasnt too cold) with a brush, not an airbrush, and it happned with testoers flat black, i dont know how it happened either......

My theory is that the paint may not have been stirred thoroughly. Resulting in too much flatening agent and not enough pigmnet in the mix.

Can it be because my paint is too old?i've this paint for about a year or so already..and i use a compressor with an air tank..The guy who sold me the compressor said i do not need a moisture tap.. So what is the ratio for the paint to be well-mixed?

[RallyRaider]

One year old paint is likely to be fine unless you are using something that has an unusually short shelf life.

Can sometimes be difficult to tell if the paint is properly mixed, probably stir the crap out of it then just when you think it is right, stir it a bit more to be sure.

As a general rule of thumb for spraying I add one part paint to one to two parts thinner. The consistency of milk is often given as a reference. Experiment with your tools and materials though, to see what works for you.

I think a moisture trap is generally a good idea. Depends on the construction of your compressor, it may already have one built in. Does the output on your compressor feed straight into the airline to your 'brush, or does it have a holding tank? If the latter then you might be able to get away without a moisture trap.

The air goes through an airtank b4 going to the airbrush...i'll try to take a pic of the compressor later..

[360spider]

Definitely too much thinner, or not stirred paint.

[iceblend]

Here's the pic of the compressor...i ever used aircan to airbrush before getting a compressor and have not encountered such a problem.

Your problem is two fold. Firstly, Your aircompressor needs an adequate supply of air. If it is in that box, it has a high chance of compressing Humid air, and thus you will get moisture in your line. You should have a moisture trap as a precaution.

Secondly, You have thinned the paint too much and hence you get pooling of paint and different rates of evaporation of the solvent. Don't thin the paint so much and spray coats a little bit more drier and thinner.

Air pressure looks pretty good. I have same setup with a compressor and tank 25 litre tank.

Good luck.
