Hi, i just recive an airbrush. Is there a place where I can see the best dillution ration for different paint.

It comes down to experimenting,PSI comes into play also,get cardboard or plastic and practice,practice,practice with diffrent mixes and diffrent PSI.Generally I thin to the consistancy of milk.you can go from 90-10 all the way to 50-50 depending on your needs.

Hi
Way too many variables to consider....make of airbrush,make of paint,what you are using for thinner,what airpressure you're using etc.Best thing to do is what everyone else does.....practice and experiment. What works for one person might not necessarily work for another.Just have fun and experiment and jot things down...all part of the learning curve.Not much help I know,but there's really no gauranteed recipes.
All the best

Thanks for all. I will experiment. Great advise

Just play with it till you get comfortable with the dillution and the airbrush. As they say Practice, Practice, Practice.

"All the way and then Some"

Depending n the brand of paint, start with the fine print on the side of the bottle. Most (not all) paint brands have some thinning recommendations on the bottle.

After that, visit the paint maker's website to see if they offer any suggestions.

My next bot of advice would be to start using the paint maker's proprietary thinner (if they have one) to reduce the paint for airbrushing. There may be other substitutes, but if you're just starting out, using the recommended brand of thinner in the recommended thinning ratio is the best beginning point.

After that, you will indeed probably have to do some experimentation with your airbrush and air pressure settings to find those happy mediums.

Happy modeling!

As others have already alluded to, airbrushing has a lot of variables that need to come together, so that the final result is what you want. The key is consistency in your procedures and methods, so that the end result is what you're basically expecting.

You haven't mentioned type of airbrush, and what type of air compressor you have. Your compressor should have a water trap, a regulator, and a storage tank. That gives you full control over air and humidity.

Now to try to answer your original question. I use a Paasche 1H single action gun. I shoot at 18-20 psi 90% of the time. My house has central air, so humidity isn't an issue even in the worst of the summer months.

Paints: I mostly shoot acrylics:
Tamiya: I dilute them 1:1 with Tamiya X20-A thinner.
Model Master: I dilute them 3:2 paint to Thinner with regular Orderless Mineral Spirits.
Lifecolor: 3:2 paint to thinner with distilled water.

Primers:
Tamiya Gray & White Primers. Both are lacquer based. Thinned 1:1 with Lacquer Thinner. Use the procedure as mentioned below.

Sealers:
Pledge/Future: Full strength
Testors Model Master Dullcoat & Glosscoat, which are lacquer based. Thinned 1:1 with regular Lacquer thinner. Use a paint booth, window exhaust fan, as the fumes will get to you.

There is nothing like practical experience. Air brushing on paper towel or cardboard is ok, but they will soak up paint, so your technique might not work on plastic. I would buy the cheapest model you can get, and just practice. I would also practice using a primer vs. not using one. When practicing, change only one variable at a time, so you understand what how it effects your painting procedures.

Hope that I've helped to get you started.
