What is a Spray Gun?

A spray gun is a tool which is commonly used by workers to paint large surfaces such as cars. Though the standard size of a spray gun can be around 9 to 14 inches but you can also buy compact models which are portable and easy to carry around, for small projects.

The working principle of a spray gun is that it uses compressed air from an air compressor to push the paint through a nozzle at high speeds, forcing a coating on a particular surface. However, there are some more modern tools known as airless paint guns which don’t use compressed air instead they use mechanical pressure. But these types of painting techniques are not commonly used by amateurs because they need an expert touch and this kind of work should be done only by professional painters because if you make one small mistake then the entire surface could get ruined.

So, the best choice for people who want to paint their cars are spray guns because they are easy to use and can be carried around easily for small projects.

What are the Basic Parts of a Spray Gun?

Spray Guns have got four basic parts which include:

  1. A handle
  2. An air valve
  3. A trigger
  4. A nozzle

The handle is used to hold the gun in your hand while painting and also helps to control it while moving or rotating it around an area. You must choose a comfortable grip so that you don’t feel any fatigue after using the gun for long hours. The air valve has got two types- an on/off valve which helps to release compressed air and a fan adjustment dial which you can use to increase or decrease the flow of paint by controlling the airflow.
