When you search “How does a paint sprayer work?”, we bet you are a newbie to this interesting tool. Aren’t you?
You do not need to go elsewhere as here we will introduce to you the paint sprayer ins and outs. Then, you will know the basis and get ready for your DIY projects.
How Does a Paint Sprayer Work?
Common parts of the paint sprayer
To understand how a sprayer works, you need to know its key components first.
Please note that not all paint sprayers are made the same. The construction differs from types to types (e.g the airless sprayers, the conventional sprayers, and the HVLP ones.)
However, they share some common parts as follow:
#1. Canister or cup
Canister is used to store the material during your painting project.
It comes in different sizes and shapes according to the type of sprayers as long as its construction isn’t susceptible to dripping and spills.
Moreover, make sure the canister is easy to refill and clean up later.
#2. Flow control knob
Located upon the spray trigger, this part allows controlling the paint output. The simple rule is, the higher the gauge is – the higher the airflow and paint output become.
The flow knob is also in place to kick-start the motion of solenoid motor inside the sprayer.
#3. The motor/draw tube
Lying at the heart of the sprayer is the active motor/turbine. Technically, on an operation, the motor pulses the piston to create force and pressure on the air or the paint in the canister. Then, the paint is pushed out of the tip toward the target surface.
If you are planning to do a big painting project, you had better go for a high-rating motor.
#4. The valve
The valve is in charge of atomizing and breaking the paint into small particles so that they can pass through the tip. Hence, the valve often moves in a fast spinning pattern.
This process decides whether the paint finish is finer or thick.
#5. The spraying tip
The tip is where the paint comes out of the sprayer. Based on your painting purposes or the sprayer’s design, the tip can feature round, horizontal, or vertical pattern.
The diameter of the spray tip is often between 1 and 12 inches.
How Does a Paint Sprayer Work for your projects?
First, you must fill the canister with paints. Normally, you have to remove the canister and fill from its top.
Secondly, configure the desired flow knob. The higher rate means there is more paint sucked up and sprayed out of the tool.
In turn, the solenoid motor starts to drive the piston into the sprayer. The pulses might be over 7000 pulses per minutes.
The paint, then, travels from the piston to the valve, in which the paint is broken up into swirl patterns.
Finally, the paint particles are pushed to pass through the tip toward the surfaces like walls or furniture.

The process is shared between different types of paint sprays. However, you can get more details on specific types. For example, if you want to buy HVLP, you should read this guide on how HVLP sprayers work in advance.
