Preparing Tools

Before starting with this DIY job, you’ll have to get all your tools and material in place. Just gather around the spray gun and the air compressor that you want to connect with it.

Preparing Tools

Depending on the area you need to cover, you’ll have to analyze the usage of paint and refilling gas in the air compressor. You’ll have to pick up primer, latex or ordinary paint, enamel for sticking, and acrylic for finnish.

Getting the Wall Ready for Spray Painting

Once you’re done with choosing the section you want to paint, it’s time to prep the surface. If you’re using water-based paints then you must use soap and water to clean it and wipe with clean cloth. Whereas if oil-based paints are your priority then wipe the wall off with spirit or lubricant.

This step can clear all the dirt and dust particles from the surface giving you a clean slate for painting. Once you’re done wiping, just let it dry and sand the surface thoroughly to even it out.

After getting done with sanding, wipe the surface again with a clean cloth and you can carry on with primer. Also check out, how to fill HPA tank with air compressor.

Testing Spray Gun

There are usually two types of spray guns that are categorised as siphon and gravity fed tools. Both of these guns have a control knob or switch so that you can increase or decrease material flow.

Testing Spray Gun

You’ll find this knob on the back side of the spray located at the top. All you have to do is move it from right to left or counterclockwise to let the paint out at full pressure. If your spray gun is working fine as mentioned then you’re ready to prime.

Priming Spray Gun

After testing, you should get started with the priming procedure of a spray gun. Just get a trash bin or a useless cardboard lying around in your stationery section. Next, you have to pull the trigger with full effort and initially some air bubbles will pass out.

Once you get the paint rushing out of the nozzle then your spray gun is completely primed. However, you have to make sure that there is a smooth flow of paint and not any stain or splutter.

Adjusting Pattern As per Requirement

If you have the latest spray guns available in the market then you’ll have to choose between different types of spraying pattern it is going to offer.

You’ll either go for horizontal flow, vertical or circular flow. These choices are often useful when you’re into graffiti art but if you’re just painting the room straight away then it won’t be needed.

Spraying with Air Compressor

After your gun is all set and prepped, it’s time to connect it with the air compressor. Just attach the hose from the air compressor nozzle to the spray gun’s back. This way it’ll add the pressure to the paint in the section.

After turning on the compressor, try moving the gun slowly either up and down or left to right on the first section, depending on your pattern setting.
