Obtaining Your Airbrush Basics Down Pat
Obtaining Your Airbrush Basics Down Pat
What's happening if you spray?

Let's explore the standard underlying concepts of spraying by having an airbrush. As soon as you what's happening and why, you'll be capable of bend and even break the conventional rules to make stunning effects and methods.


"Knowledge is power"

Aerosol spray

Airbrush basics start out with the spray. Knowing what's happening will give you the strength to manipulate and modify the impact you're looking to achieve.

Technical jargon warning.

An aerosol spray is an assortment of a couple of liquids by using a gas. The liquid gets broken up into tiny droplets, atomized. The atomized liquid is suspended from the gas, usually air.

Liquids in suspension usually settle. It gradually falls on the floor.

End of technical jargon.

As soon as the liquid hits the atmosphere stream the force of your moving air breaks up and atomizes the liquid into small globules (think tiny spheres yet not nearly so perfect and neat like a sphere must be).

As soon as the globule hits something it forms a dot. Before impact with the surface, the width and height of the dot is determined by how much the droplet dries.

Greater air pressure = smaller dot = drier, rougher spray texture

Lower air pressure = larger dot = wetter, smoother spray texture

A huge number of these tiny dots (the majority of them smaller than you can observe) form larger shapes as dependant upon the person.

Enough to actually break up the paint being sprayed, though users try to spray with as little pressure as possible.

Thicker, chunkier paint = greater pressure to pull and atomize the paint

Runnier, more uniform paint = less pressure to pull and atomize the paint
