10 Expert’s Guide To The Pros and Cons of a HVLP Sprayer

Spray Finishing? Why Should You Buy HVLP?

This innovative process for spraying paint is more popular today than ever before thanks to continuing advancements in technology and how the different types of airless spray delivery methods have been improved over time on job sites around the world.  Since the technology was introduced over a century ago, professional contractors have preferred airless paint spraying for many reasons:  Airless spraying increases speed. Airless spraying is faster, so more jobs can be completed in less time, using less labor – plus, it’s great for jobs with a short weather window. 

Airless spraying improves overall finish quality. Airless sprayers produce an even coat of paint (referred to as the mil build) on all types of surfaces, leaving a high-quality finish.  Airless spraying is also very versatile. Airless sprayers can be used for a wide range of coatings for both interior and exterior jobs and can easily be transported around job sites.

Another fluid spray method is High-Volume, Low-Pressure – or HVLP. These systems also utilize compressed air, but in a different way than standard air spray systems.  With an HVLP sprayer, a turbine delivers a large volume of air at a much lower pressure to atomize and spray the fluid. In fact, the unit must be 10 PSI or less at the air cap to qualify as HVLP.  These systems are designed for smaller fine finish jobs because they provide the least amount of overspray and unmatched precision forthe highest quality professional finish.

The Finish

Or, if you are a commercial painting professional you’ll find it hard to use any of your other equipment and tools due to the ease and precision you achieve when using your sprayer. Your will spend less time on projects and you’ll spend less money on paint.


You’ve got a paint/finishing project to do and not only is there a lot of it to cover, you also want a smooth, even coating. Let’s be honest, doing it with a brush will take time and probably not leave the best of finishes. Now it’s time to consider using a HVLP spray gun.


With the lower velocity of HVLP, this produces a softer, easier to control spray. This means that much more of the finish ends up on the surface, with figures as high as 85% efficiency for some systems. With some finishing substances being harmful to your health and the environment, HVLP is more and more becoming the industry standard.


HVLP – the future of spraying

This may be the deciding factor in your purchase if your project has to be absolutely perfect, which could make you lean towards the compressor. But don’t think that the lower pressure of the HVLP will mean a bad finish, in fact the quality of finish of these systems can be identical to the best high pressure spray finishes.


Fast becoming the industry standard in many sectors and with more emphasis on the environment, it’s hard to see it not becoming the only way to spray in the future. If you already own a quality compressor, it may not seem like it’s worth it right now. But if you need lots of jobs doing and the cost of paint is getting too much, these will prove to be a sound investment.

Proper setup of your sprayer is an important step to keep it running at maximum performance and efficiency. Before operating your sprayer for the first time, or any time, always perform the pressure relief procedure to ensure your sprayer is de-pressurized.

Engage the gun trigger lock.

Turn the on/off switch to OFF.

Turn the pressure control to the lowest setting.

Reverse the tip and disengage the gun trigger lock.

Hold a metal part of the gun firmly to a grounded metal pail and trigger the gun to relieve pressure.

Engage the trigger lock.

Turn the prime valve to the PRIME, or DRAIN, position.


With the pressure relief procedure complete, it is time to prime the pump.

Engage the trigger lock.

Remove the tip and guard from your gun.

Place the fluid intake hose into a paint pail and place the drain tube into a waste pail.

Be sure the prime valve is in the PRIME, or DRAIN, position.

Turn the pressure control to the lowest pressure setting.

Turn the on/off switch to ON.

Increase the pressure control until the motor starts. Allow paint to circulate through the sprayer until paint flows smoothly out the drain tube.

Turn the on/off switch to OFF.


You have now primed your pump with fluid. Next, it is time to prime the hose and gun to be ready to spray.

Hold the gun against a grounded metal waste pail, disengage the trigger lock, pull the gun trigger and hold.

Then, turn the prime valve to the SPRAY position.

Turn the on/off switch to ON.

Let the pump run until you see paint come out of the gun. Then, turn the on/off switch to OFF and release the gun trigger.

Move the gun to the paint pail, pull the gun trigger, turn the on/off switch to ON and let the pump run for about 20 seconds.

Then, release the trigger and allow the sprayer to build pressure.

Engage the trigger lock.

Screw the tip assembly onto the gun and tighten.


It is recommended to use a test surface and test your spray pattern. Test patterns should be sprayed on scraps of cardboard or other waste material. To test the spray pattern, follow these steps…

Turn the pressure control knob to a mid-way position.

While holding the gun 12 inches from the test surface, disengage the trigger lock and spray a test pattern.

If the pattern has heavy edges, often called tails, slowly increase pressure and continue to spray test patterns until the hard edges are replaced with a soft, blend-able spray pattern. 

After following these steps, you’re now ready to spray. When spraying, be sure to follow these start up steps, as well as our safety recommendations, best practice spray techniques, and cleaning steps.
