Spraypainting

A device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface when using the spray painting technique. The most popular varieties atomize and guide the paint particles using compressed gas, often air.

Airbrushes gave rise to spray guns, which are often distinguished from one another by their size and the size of the spray pattern they produce. For detailed work, such as fine art, painting nails, or photo editing, airbrushes are used in place of brushes. Larger equipment is typically used for air gun spraying.

It is often employed to evenly coat huge surfaces with liquid. Different spray patterns are possible with sprayers that can be either hand-held or automated and feature replaceable heads.
Cans of one color spray paint are lightweight and convenient to store
