Airbrush questions

Tools, Techniques, and Reference Materials Painting and airbrushing

Hi all, I need some advice on my airbrush. I’m currently mixing my Tamiya Acrylics with 99% iso alcohol. I was wondering if that is what I should be using, or is there a difference with Tamiya’s thinner. Also can someone tell me when you airbrush Future, do you thin it down or is it straight from the bottle?

Thanks,

sincky, i use tamiya brand thinner because it has a retarder that helps diminish tip dry and helps the leveling properties of the tamiya paints by slowing the dry time a hair. i thin with it only and the 200ml jug will thin tons of paint for the price so i consider it well spent money. i clean my airbrush with another agent as to not waste the rather pricey tamiya thinner, but for me, $7 for thinner that will last for a long, long, time is money well spent. the iso will work but you may experience some tip dry and rough finishes if you not careful.

i spray future straight from the bottle with 15 to 18 psi. later.

Thanks, you answered my question and solved the paint problem I was having. I wondered why it was looking like sand paper!

Thanks again!

sincky, what kind of air pressure are you spraying with? you dont need to be spraying at much over 20 psi and i rarely get above 15 during my spray sessions. there are all types of things that can cause “orange peel”. paint not thin enough, air pressure too high or low, and like you’ve found out, thinner problems. later.

Hi,

I’m having a problem with Tamiya’s flat white. Whether I mix it with water or the Tamiya thinner, it either splaters when it comes out of the airbrush or it doesn’t come out at all and just collects inside the airbrush.
Nothing is wrong with my aribrush because if I clean it and use another colour like interior green or flat black, it sprays beautifully.
Is there a particular ratio for white. The paint itself isn’t very thick but it’s quite cohesive.

Thanks

you may have to strain the paint thinstix. maybe thin it a little more as well. later.

But be careful with white. It’s very easy to get it so thin it won’t cover well, especially over darker colors.
