I'm using a Thompson Chandler, which is a subsidiary of Badger plus some
Badgers mostly the double actions at this point. TC uses a cup the Badgers
use a jar.
I seem to get very small amounts of splatter. Usually when I first pull the
trigger on the paint. If I can start off the model it isn't to bad, but
otherwise I end up with spots of paint. I keep it clean and have been varying
the thinners and air pressure fairly low 8 to 20 psi but the problem seems
What should I be looking at?
As Alan said, do you have a water trap?=20
The signs of water and not paint coming out are splatter that then blows of=
f the paint but leaves streaks behind IN the paint. A water trap stops the =
condensation in the line (but remember to empty it -- just like a spit valv=
e on a brass musical instrument -- from time to time).=20
If the splatter is paint and it leaves paint streaks behind it may be press=
ure buildup causing a "spurt" when you press the trigger.=20

one is inline on the braided line I'm using (soon to bereplaced anywya.
Ho smear. just little dots. And just when pulling the trigger the first
time after even the sammlest rest and the pressure builds up again. Not
that I'm using fire hose like pressures 8 - 15 lbs.
Try thinning your paint more...sounds like it's drying in the tip. If
you can also clear it by running the needle closed and then open, that's
Used to see that...then I started thinning my paint properly and it
stopped. At least that's what I've seen using enamels, and I would
think acrylics or any paint that dries faster might be even more prone.
Another thing of note is that the pressure may also build up in the line
when you pause, and you may get a bigger initial blast that you want. I
find it's always best to start my pass off the model anyway. I keep
spare chunks of cardboard around just to test my flow on.
Just out of curiosity what is the temp vs dew point temp when you spray ?
I've had problems spraying on a hot day when the humidity was very high
and wound up spraying small ice crystals and had clumping of paint out
of the airbrush nozzle.

Clean is not the issue. I have it down good how to strip and clean these
particular airbrushes. I never let them sit with gunk in them, I always
rinse with thinner (if enamels) and then water next or if it's acrylic.
I have to think I'm not thinning enough, it's difficult though getting a
good mix for me. The looks like skim milk thing is kinda vague if your
paint is a dark brown or green.
Yes. The newer Model Master enamels are billed as "airbrush ready", and
pre-thinned. But I even thin those, and get excellent results. I have
an adapter for my Badgers that lets me fit Testors jars directly to my
Badger 200 and/or 150 - I top off with thinner and mix before use;
"airbrush ready" or not.
Proper thinning is even more critical with gloss paints - way thinner is
far better. And I use Model Master enamels and airbrush thinner. The
airbrush thinner is a bit hotter than the brush cleaner/thinner.
I also don't mix one manufacturer's paint with another's thinner. I
like to think of paints/thinners as being formulated to work together.
That doesn't mean that another thinner won't work, it's just the way I
Too humid or too dry both can cause problems when spraying ANY kind of
Which BTW also has an effect on how much orange peel and fisheye you
can/will see in a spray paint job
I just check the weather channel for dew point vs temp before I spray
and plan accordingly. I'm now forced to spray outside or in the garage,
SWMBO will not tolerate airbrushing anywhere in the house. I have snuck
it a couple of times, but she don't know yet

Actually, finish is not a problem. I do seem to get beautiful, flat,
smooth, thin coats.
I used to worry about the thinners, but judging by odor (for enamels,
anyway) they seem pretty much the same. I have Floquil, MM, Aeromaster and
Humbrol thinners and a gallon can of paint thinner I got at Lowes. Frankly
they seem interchangeable, it has never been a real problem.
Acrylics I'm a bit more fussy about, but even still rubbing alcohol and
glass cleaner/windshield washing fluid seems to work really well which I
attribute to the surfacants in it.
I have all of those myself, but I haven't used any of my Floquil stuff
in quite some time. I even have a good stock of Aeromaster paints still
around. In general I prefer Model Master, and they keep adding colors
so I find I can get more and more of what I'm looking for from them
If you use a wine-taster's sniff test you'll find each a bit different.
Same base vehicles for all enamels, but I think they are or can differ
chemically just slightly. Like with the paint retarder that you can get
Forex: I know that the airbrush thinner is "thinner" than the brush
cleaner/thinner. That and that it's "hotter" means you may be able to
get away with using less of it, and also will alter how it flows through
your airbrush. That's something else to pay attention to - how "thick"
your "thinner" is; it's specific gravity. Thinner thinner is better,
just like thinner paint.
I think I do what I do because I had a paint mix actually curdle on me
once...can't recall what I was mixing, but I seem to remember altering
my habits after some such. So now I stick to using same brand
I use very few acrylics - for light lenses and for tinting canopies. So
mainly just clear red, yellow, green, blue, and/or orange. Tamiya...and
even I use their thinner! But here you illustrate the point of all
thinners not being equal even better.
I have never mastered the art of thinning acrylics to the point where I
can airbrush them reliably - mostly they dry between brush and target
and produce a cute flocked finish - useful for Special Night, perhaps,
but not for anything else.
However I always use the manufacturers thinner or a known appropriate
substitute. I came to this decision after thinning some Revell
synthetic enamel with white spirit (which is known as mineral sprits in
the US, I believe), the thinner I used for all other enamels at the time.
The resulting mixture sprayed well, but refused to dry. After three
days it was still sticky, not liquid but not touch-dry either. I did a
lot of digging around the internet to discover that the Revell paint
used an unusual mixture of hydrocarbons as a thinner, certainly not
white spirit. All that was on the can was the usual warning, "Use only
Revell thinners" or something similar.
So, although you might get away with using the wrong thinner, it's risky
and you could end up with a fly-trap.
Humbrol paints explicitly allow the use of white spirit as a thinner,
and Xtracolor specifies white spirit. Otherwise, I use white spirit to
clean brushes and the airbrush after enamels: with brushes I give a
final wash with detergent to get the solvent out of the brush, with the
airbrush a quick dose of airbrush cleaner (usually toluene) gets rid of
any stubborn leftovers.
