A gravity spray gun is also suitable for small places; also, it needs less air pressure than siphon guns.

And the last one is the pressure feed gun. With two different types of hoses, the pressure-feed gun efficiently covers a large area.

Step 3: Prepare the Place Where You Want to Paint

Prepare the area where you want to paint before start painting. You may want to paint on a specific surface on a wall or any other surface. In that case, you need to cover the area you do not want to paint. You can use old clothes, plastic sheets, or scrap lumber. Regardless of these, you can use painter’s tape for easy application.

Step 4: Wear the Protective Tools

Once you’ve secured the object, it’s time to take your protection. This is because when you use spray paint, you will be exposed to dangerous fumes and particles. Wear protective equipment to protect yourself from those harmful particles.

The protective gears include safety glasses, gloves, masks, respirators, etc.

Step 5: Clean the Area

Neat and clean places are easy to paint without any disruption. If you are painting a dirty area, you will not be able to set the paint on it smoothly and perfectly. Even a little oil or rust on the surface will hinder the application of your smooth paint.

So, ensure there’s no rust, oil, or corrosion on the surface you’re going to paint.

How to Set a Paint Sprayer with an Air Compressor?

Now it’s time to prepare your air compressor sprayer. Here are the instructions you should follow for best experiences:

Feed the Air Hose Coupling

Feed the air hose coupling of the air compressor into the HVLP paint sprayer. Use the Teflon tape to firmly seal the connection of the air hose and spray gun.

Some air hoses come with quick connecting couplings. When your air hose fittings include such couplings, using Teflon tape will be unnecessary.

Turn the Air Compressor Switch on and Adjust the Pressure

Your air compressor becomes ready to use after you insert the coupling. Now, turn on the air compressor and adjust its pressure using the regulator.

Generally, the pressure between 12-25 PSI is perfect for the spray paint application. Look for the manufacturer’s instructions when adjusting the pressure of the compressor.

Take the Thinner

Take a little amount of thinner into the paint cup to test the spray gun’s usability. The paint cup or tube is attached to the painting gun you’re using.

Adjust the Metering Valve

Slightly Open the metering valve of the spray gun by lowering two screws over the handle.

Check the Usability of The Nozzle

Take the Paint gun and squeeze the trigger with your finger. For the first few minutes, only the air will come through the nozzle. But after some time, the thinner from the paint tube will come through the nozzle.

When the thinner comes out, you’ll understand that the air-compressed Sprayer is ready to use.

Remove the Thinner from the Spray Cup

The thinner you’ve put into the spray cup is only for checking the nozzle’s efficiency. So, when you ensure that the spray gun’s nozzle is working efficiently, empty the spray cup.

How to Apply Paint Through the Spray Gun?

This is the final part of using a paint sprayer attached to an air compressor for painting. After preparing the paint sprayer and compressor, follow the followings steps:

1. Mix the Paint and Thinner into the Tub

Prepare the paint for applying to the specific area. If you have a container of longtime stored Paint, remove the strain from them. Moreover, remove all the particles that harden the Paint.

You can use the paint filter to remove the strain and the hard particles. Put the paint into a container after filtering. If you have just bought a new container of paint, directly put them into a separate container.

2. Make the Paint Thinner

Use a well-branded paint thinner to reduce the thickness of the paint. Directly pour the thinner paint-refilled container. Reduce the paint’s thickness by 15-20% of current times.

After reducing the thickness, the paint texture should look like aerosol spray paint. Take some of the thinned paint into the spray gun tub and pull the trigger of the gun. Thus, you can justify how the paint looks like.

3. Take the Thinned Paint into The Sprayer Tube and Lock It.

After you accomplish thinning the paint, take them into the sprayer tube and lock it. Don’t overflow the paint tube.

The paint tube should be filled in such a way that 1/3 of the tube remains empty.

4. Applying Paint

At first, do some practice of paint application. Hold the spray gun at parallelly 5-10 inches far from an unused surface. Now, pull the paint gun’s trigger and move in a sweeping motion.

If you can paint the surface smoothly without causing any clots, then you’re ready to paint. Now, apply the paint directly to the surface that you want to paint.

5. Refill the Tube and Allow the Surface to Dry

When the paint gets finished from the tube and your painting isn’t done, you can refill the tube. Allow the painted surface to dry for some time.

Recoating is compulsory most of the time to ensure a durable and even finish. So, recoat the surfaces when you complete your first coating on the surface.

6. Primer Application

If you didn’t get the expected smoothness after paint application, apply the primer. But, before you prepare the primer for application, make sure the painted surface is perfectly dried.

Remove the unused paint from the sprayer tube and refill it with primer. If the primer is thick, make it thinner by using the paint thinner. Apply the primer on the paint-coated surface and get an even finish.
