How much water do you typically add to the paint?

I usually add between 25-40%. It just depends on how thick the paint is when I mix. Some of my paints have been with me for a few months to a year. They tend to get a bit thicker. No problem, they just get a tad more water. Mix and shake well then airbrush.

The paint I am using to paint my B-17 is relatively new, so it only took about 25% water to get the consistency I needed for the airbrush.

There's a lot of variables as to thinning( air pressure,needle/mix cap size, viscosity of paint ). I've read in some other kit bashers threads that with Home Depot samples they thin by as much as 65% with either windex or Isopropyl. I'd suggest starting at 50% and try it out on paper plates( the dollar store kind) If your air pressure is not adjustable play with the thinning until you get the consistency you can control the flow with out running the paint.
I wouldn't use plain water to thin, stick with either windex or alcohol.( both work better than water at keeping the flow smooth and help the paint to dry faster).
If you're using craft store acrylics, they will probably need less thinning.

Thanks for the tips guys. My B'day is coming up and I hope to be getting the Dynam BF-110. That plane will be my next big repaint this winter. First time with an airbrush

So just regular acrylic paint? Safe for foam? No need to use expensive enamel paints from hobby shops?
I tried some paint from spray can at Ace hardware and it makes foam swell up, "dinosaur skin"! !
Great tips for thinning
Thx

The paint I buy from Home Depot is regular flat latex house paint. It is water soluble and is a very easy clean up. I don't use the enamels or the spray paint in cans. Others do, but I have found that Home Depot will computer color match nearly every color I need r want. It cost $2.93 fr a 7.5 ounce sample. That is enough to paint a plane numerous times with paint left over. "Hobby store" paint at nearly $4-$5 for a 1/2 to 1 ounce ounce bottle just makes no economic sense to me.

Krylon Fusion spray paints work good on Dynam foam. No problems with it getting sprayed directly onto the foam.

If you're not looking for specific color matching, the small bottles of craft paint sold at Michaels, Hobby Lobby, Walmart can be used to air brush on any foam as they are fully water based.

Apple Barrel and Craftsmart brands flow very nice when thinned with Isopropyl and at 79 cents a 2 oz. bottle they're very affordable, 4.99 for 16 oz. bottles.

Liquitex makes the best water based spray cans in some amazing colors

The Michaels near me carries Createx and Wicked Paints designed for airbrushing and they require less thinning.

One last thing, stay away from the Folk Art brand for airbrushing. Very difficult to get consistent flow and they tend to clog the airbrush ( my experience anyway).

Guess it's more than one last thing , The Liquitex spray cans are expensive, but the amount and quality of the paint is outstanding and there are a number of different aircaps available for different effects. The caps can pretty much turn a spray can into and airbrush.
