How to Use a Paint Sprayer: Step by Step Guide
Below we have mentioned several steps on how to use a paint sprayer.
1. Select a Paint Sprayer for the Project
You will come across mainly 3 types of paint sprayers at present:
- HVLP (High Volume Low Pressure) sprayers
- Airless sprayers
- Pneumatic sprayers
2. Practice Using the Device
- After selecting the paint and the sprayer, make it a point to test the device on a big piece of cardboard. Do not make any unnecessary haste and spray gradually and have a few pieces of scrap material at your disposal.
- While using a paint sprayer you would like to get an even look applied to the surface quickly. Make experimentation with different spraying methods till you succeed in getting an even and consistent type of paint onto the scrap material’s surface.

For instance, frosted paint can be applied on a glass surface for reducing glare.
What is HVLP Sprayer?
HVLP (High Volume Low Pressure) sprayer makes use of a steady air volume for propelling the paint onto the desired surface from the gun’s tip. These sprayers are well-known at present since it is easy to regulate the low pressure while creating lesser waste.
HVLP sprayers are actually recommended for applying thinner paints and are more costly to rent or purchase. A compressor is used by this sort of sprayer for atomizing the paint.
Majority of the models enable the user to regulate the pressure of the spray such that it will be feasible to paint the difficult spots easily.
What is an Airless Paint Sprayer?
An airless paint sprayer is going to use an electric pump for propelling the paint via its tip while applying high pressure to the reservoir of the paint. While painting, the paint comes out through the sprayer’s tip and it ultimately dries up with a glass-smooth coating.

3. Test the Paint
At this stage, you are almost set to mix the paint. Prior to getting started, it might be sensible to run some paint through the sprayer for ascertaining how it is able to handle the paint sans the thinner.
For getting this done, simply spray some standard paint onto some cardboard. In case the paint is applied uniformly, then probably you are lucky and there is no need for you to thin the paint.
However, in case the paint comes out with clumps then it might be needed for you to thin the paint. In that case the next step will be needed.
4. Get the Paint Mixed
So you have performed the test and have come to the decision to thin the paint. There is no need to become stressed since this step is quite easy.
First, you are suggested to review the can of paint for seeing whether there is any thinning guideline from the manufacturer. In case there are no instructions, you will have to get the job done on your own.
For this, you might need to make some experiments, and you are advised to do it slowly and also test spray frequently. After getting a thickness that is working for you, note it for the subsequent usage.

Make use of shears, scissors, or a knife for trimming the bristles of an inexpensive paintbrush to around 1 inch in length.
Make it a point to pour around a couple of cups of lacquer thinner or paint thinner into a small bucket.
Next, the spray gun has to be disassembled and all the gun components must be placed for soaking into the lacquer thinner.
Put on a pair of gloves (here, you can use blue nitrite gloves). After putting lacquer thinner on a clean piece of cloth, the over-sprayed paint has to be rubbed off from the sprayer’s body and frame.
Start to clean the paint off from the gun while making use of the trimmed brush.
Finally, the used thinner has to be filtered utilizing a clean piece of cloth and the thinner has to be put back for reuse into the original container.
