Thining Acrylic

Saw my name mentioned so thought I'd throw my 2 cents worth in.

I've used Tamiya for quite a few years and if I thin the only thinner I use is water straight out of the tap. No problems so far. I find that in a lot of cases (flat black for example) you don't have to thin the paint. If it's the consistency of milk ... spray away.

I own acrylic varnishes used in fine arts (Talens, a dutch company) who diluted in ... mineral turpentine, to my great astonishment, but mixing it with water and/or alcohol of any kind seems to me out of the point (fact is that there are different kinds of acrylics which dilute with different kinds of thinners (a friend of mine diluted Lifecolor, which is an Italian brand, with alcohol, and it took him a whole week to extract every chip of clogged paint out of his airbrush; on the same way, and as far as I know, there are very few Vallejo/Andrea paints which dilute with anything but water; Gunze and Tamiya behave the same way because -and I hope I'm not saying a big BS- Gunze produces for Tamiya the same way Floquil produced Aeromaster paints (this last one I'm sure, as "Floquil" was printed of the little cardboxes that packed Aeromaster paints by six bottles) these few points don't mean in any way that hues are the same; it's only the composition of paint which is the same.

dirk75,
Doesn't sound like a good idea. Use the Gunze
thinner. It may cost more but it's compatable and that's one
thing you won't have to worry about. Don't want to gum up
your airbrush or ruin your models finish.

You can use straight water and a drop of diswashing liquid to break up any surface tension, or you can use isopropyl alcohol, or you can use the manufacturer's recommended thinner, but I don't see how mineral turpentine can work. It shouldn't be soluble in water--or at the least not very well.

PS According to shermanfreak, you can use Tamiya acrylics straight out of the bottle with no thinning. Try it.

I would not do it. Have this guy show you the diluted paint.
