Airbrush use Vol 1
Earlier I posted about airbrush equipment, well without knowing how to use it what good is that.
First off you need a few things.
1. Moisture trap: A moisture trap keeps moisture out of the air supply that feeds the airbrush. There are 2 kinds some are attached to the regulator, and some are inserted into the airhose. Actually I have seen some that attach right below the airbrush so there may be 3 kinds. What the moisture trap does is keeps moisture away from your work, if you don’t you will get spatters on your artwork.
2. Air Regulator: The regulator controls the volume of air that flows to the airbrush. This is important because the air atomizes the paint and produces the spray. The regulator allows you to select different volumes of air in order to be able to produce different types of spray dependent on viscosity of paint or spray materials (varnish, finishes, inks etc…). Each material you spray has different air pressure requirements.
Air pressure: Normally you will spray acrylic paints at around 15-20 PSI, if you are spraying acrylic inks go down to about 5-7 PSI.
Thinning paints: If you are not using pre mixed airbrush paints I recommend getting airbrush medium. Airbrush medium has acrylic polymer in it, this will help thin the acrylic paint properly as opposed to just using water which will only thin the paint and potentially cause it to run and spatter. When thinning paint you want a consistency of skim milk.
Thinning acrylic inks: When thinning acrylic inks such as FW inks you can thin with alcohol , you need the highest percentage alcohol you can get 95% or better.
