| Reducing or thinning paint for use in
your airbrush. |
Written with help from
Doug Probst airscapes
The general rule of thumb
with most Acrylic Colors is reducing it with distilled water until it flows
like milk. Please understand here that it depends on how much air pressure you
are running and the type of airbrush you are using. Over reducing some paints
might have an adverse effect and the paints might not adhere as well. Always
check the product tech sheets if available. Key to this is experimenting to
find what reduction works best for you and you situation. Beware that there is
a difference with paints made to use in an airbrush and craft type paints, the
pigments are ground finer in paint made to use in an airbrush they generally
will flow much better being less hassle to spray thru your airbrush.The amount
or reduction also depends on the size of the nozzle in your airbrush a 0.5 mm
nozzle will spray much thicker paint than a 0.2 given the correct air pressue
is being used. Extenders that the paint companies make more often than not do
not make the color thinner but do make it more transparent. Below is some
information I have put together for several different products I hope you find
it helpful.
Auto Air: Reducing or
thinning.
Auto Air: 0.3mm
needle, nozzle size: Transparent Colors thinned with Auto Air Reducer
approx 300% or more (3 Reducer : 1 color)
0.2mm needle, nozzle size:Transparent Colors thinned with
Auto Air Reducer approx. 500% or more (5 Reducer : 1 color)
***To improving
atomization when using an airbrush, Auto Air Reducer may be used to thin
paints. Often, colors are reduced up to 400% (Auto Air Reducer 4:1 Auto Air
Color) when using an airbrush. Mix ratios may vary per color and Color Series.
Exact ratios are not required
Createx Colors thinning
or reducing:Airbrush Extender a transparent medium which will dilute the
color to a lighter value. Will increase transparency in opaque and pearlized
airbrush colors. Add until desired transparency or color shade is achieved.You
can us distilled water to further reduce as needed.
Createx Acrylic
Colors:Multi Surface Acrylics may be thinned with water or extended with
Createx Mediums
GOLDEN Airbrush
Colors are formulated from a safe and archival1 100% water-based acrylic
emulsion, incorporating only the most lightfast pigments available.Viscosity
ready to use, no dilution required as they are finely ground, they easily spray
through the smallest orifices available for airbrushes.GOLDEN Airbrush
Transparent Extender can be added to the Airbrush colors to yield more
transparent colors without jeopardizing the film integrity and permanency. In
fact, lowering the pigment load by adding the Extender will actually increase
the film's durability and frisket performance.

filtering necessary.
SOLVENT BASED COLORS
Solvent based paint isa hard one as there
are
Solvent based paints are a hard one to
discuss as there are so many different systems out there on the market. By
solvent based I'm referring to the automotive paints we use for airbrushing
murals, flames, graphics on bikes, cars, trucks, etc. With these the best thing
to do is to get to know your local paint jobber REAL well. Most if not all the
tech sheets put on these products relate to painting cars and not to applying
these products thru an airbrush, please keep that in mind when reviewing tech
sheets. Most often when used in an airbrush you must over reduce the products
beyond what the tech sheets say to get them to flow correctly thru an airbrush.
Some products like Dupont Chroma Base use what's called a Base Maker instead of
a Reducer like House of Kolor. Base makers will in most cases not make the
color thinner allowing it to easily flow thru your airbrush in fact some make
the paint thicker. With products that do use a reducer thinning or reducing the
paint for use in an airbrush is best accomplished with medium or slow temp
reducers. Thinning solvent based paints is a very personal choice as to how
much you thin or reduce it, this will take some experimenting on your part I'm
afraid. With the house of Kolor paints I use I generally reduce it with slow
reducer at about 50% paint 50% reducer depending on the color maybe a bit more
reducer. The tech sheet calls for two parts paint one part reducer for spray
gun applications on most House of Kolor products so you can see I do over
reduce it according to what the tech sheet says. Again a good starting point
might be to get it to flow like milk. Beware of using a solvent based product
in your airbrush that requires adding a catalyst.
