Acrylic paint thinning

[graham_fuller]

Can someone tell me the ratio of paint to thinners, and also the best pressure to run?
Cheers,

I found this one out the hard way  It's about 25% Paint to 75% Thinners, but a search of the forum should uncover some more in depth answers.

Thanks Stinky, there isn't much that comes up when searching our site.The web says 60% paint and 40% thinners. I started with 50-50 and it wouldn't spray out of the gun, just splattered. Finally thinned till it looked like water.I think the pressure could also be important.Any more ideas?
Cheers,
Graham

I mix 1 part paint to 1 1/2 part thinners.

Have a look through this lot Graham - http://www.hotholdens.com/forums/?showforum=82
Some good tips from painters and amateurs alike, I did the "splatter effect" thing too 
This one gives a good quick read - http://www.hotholdens.com/forums/?showtopic=3572
Recommends the 1 to 1.5 which would be 2 to 3 or 40% to 60%

G'day graham,
          The best way is to mix the paint in a clean container and not in the pot and add it to the pot once properly mixed about 50/50 would be the norm though I have found that paint consistencys do vary at times so a little more or less thinners is sometimes required.
          As for gun pressure this depends on the type of gun being used.  For a general purpose low pressure gun 30 to 40 psi normally works ok and an acrylic gun 35 to 45 psi I find gives good results. 
          Do a test run on a piece of tin or old thinners drum.  If the paint goes on heavy and runny more pressure is required.  If it goes on dry and alot of overspray is evident the pressure is to high.
          Your gun should also have adjustments to vary volume of paint and fanning the air adjusting these will also help minimize overspray and runs in your paintwork.

                              Hope this helps
                                        Frank
