Default Can you airbrush the Acrylic Craft Paints?

Has anyone used the acrylic craft paints in an airbrush. It seems like an inexpensive way to paint but I wasn't sure how well they would cover once thinned. If you have, what percentage did you thin it and did you just use water? Are the metallic paints any different to thin from the standard colors?

Thanks,

Tom

Tom,
Depends on the paint. If you use something like Faskolor, you spray it straight, no thinning required. Other wise just play with the paint till you get a good spray pattern and coverage.
With metallics, you may run into a problem, depending on the flake size, if so just go to a bigger size tip on the air brush.

Thanks Brad. I was talking about the craft paints like at Michaels or Hobby Lobby ($1.50 or less a bottle). The metallic is a very fine flake so it should be OK. I'll buy a couple of bottles and try it. Even if it doesn't work, I'm only out $3 and some time cleaning up the airbrush.

I've used them (Wal*Mart craft department) and they worked great. I didn't thin with water though I used about 50/50 rubbing alcohol.
Just make sure that if you want a gloss finish to get gloss paint and buy the bigger bottles, the little 77 ones don't go very far.

Thanks for the tips Forrest. I do want a gloss finish. I was going to try putting a light coat of gloss WBPU on top to seal it and give it a gloss finish. I'll practice on some scrap foam first.

Thin the paints with windex when airbrushing. It's a old nail salon trick and it works, faster evaporating and the color sticks better.

As far as clear, remember it adds weight. Go easy on it!

Will the blue Windex discolor white paint?

that's good question Paul, I am not really sure. What I would try to do is paint a piece of scrap foam, If your'e anything like me you have lots of it, and then put your clear on it. Give it few days to cure and then cut it in half and have a look.

scrap foam?.....do you consider 5 8'4' 3" sheets, 2 8'4' 2 ", 3 8*4 8", and a brick of blucore enough

I wanted to try the spray can stuff from the craft section, but I did find some H2O based acrylic clear coat...I was just being lazy and didn't want to mix it:p

See I knew you'd have some! Come to think of it I don't think I've ever seen any water based clear either.

Mornin Guys,

I was going to try the clear gloss water based polyurethane over mine. I'll go throw a coat over some acrylic paint test patches I've got on foam right now. I'm hoping to get my Magpie painted this weekend and I had the same question.

I got some acrylic metallic paints at Michaels last night and put them over my polycrylic to see how they dried. They dried overnight and are very shiney so I wasn't going to top coat them. I'll go try the polycrylic and let you know.

I would think any water based clear coat would be fine over acrylics but you always want to try a test piece first.

Tom

Testor's clear is foam safe and won't react with the acrylic. It's heavy, so go lightly and the results are great!

That's good to know Joe. I had read that Testors enamels will eat foam but I tried them on some scraps and they worked fine. I haven't painted a whole plane yet but I would think they would be lighter than acrylics once dried.

I put a coat of Olympic water based polyurethane over a test patch of Folk Art and Deco Art acrylic metallic craft paints and it's dry to the touch. It looks really good. Nice smooth gloss finish.

acrylic paint can set up quick if you're used to using other water based paints in your airbrush. Remember to flush it out well in between sprays to avoid clogging.

I have a cheap Badger, basic model, I picked up at the LHS. It is a really nice inexpensive gun. I got the whole deal for aroun 40 bucks if I remember right. It works really well for spraying the acrylics.

I made the mistake of thinking if the cheap AB will do the job, then an expensive one should do it better... WRONG! An expensive airbrush will do very fine lines better, but for covering large areas the cheap ones are best.

Of course I still haven't learned, I just picked up a gravity feed touch-up gun knowing that... hey, it costs more than my Testors external-feed hobby brush, so it must be better...
