How To Adjust A HVLP Spray Gun?

Here is the main point why do we need to adjust HVLP spray guns? As you know, HVLP is known as a high volume and low-pressure spray gun. For this term, you might get the idea of why it needs an adjustment before using it on the surface.

Remember, it’s not a gun that uses high pressure to atomize the paint. That means you must be tricky in this part because it’s only 10 PSI, not 50 PSI like other paint has.

Only the best setting can ensure that the paint can remain on the surface without rebound and wasting. So, let’s jump into the deep and dig out all the methods of adjusting HVLP spray guns in the best ways.

Choose The Right Air Supply

A spray gun always depends on the right function of the air. So it’s always important to choose the right air supply. Take your spray gun and check its direction. It will help you to find the parameter for the cubic feet of paint per minute. It’s amazing to hear, isn’t it?

The air compressor you choose should have the ability to produce enough volume. Such air pressure helps you to achieve the expected result. But how do you set it perfectly?

Did you notice that there is a regulator that comes with a compressor? This is the key tool you can configure to set the air pressure. But, of course, you can also use it to keep the lines clear as well.

Selection of the right tips

Wait, you don’t need to deal with the air pressure regulator anymore after you set it once for the job. Now take a close look at the tip. You must pick the right tip because several tips come with a gun.

Choose the tip that is perfect for your job. Take my suggestion, pick the smallest tip among the options. It is almost perfect for most of the project and material.

Do you know the measurement of the tip? Let me explain. Always pick 1.0, not 1.3 or 1.4, for your smaller project because the last two are for larger projects. One more thing, you might need to use 1.8 or 2.3 if you work with primers. That means it depends on you which tip you should use and install.

Set the Gun

After every use, you must ensure that the gun is in proper setup. That means every time setting the gun is important. Don’t skip this part to complete the full setup process.

Otherwise, you’ll get sub-optimal results. But, trust me, it’s simple to complete. If you don’t believe it, then follow the instructions I’m going to discuss.

  • Take a masking paper. Tape it to the wall.
  • Set the pressure of the gun’s inlet and keep the air volume pulled. Oh, don’t forget to keep the control knob close.
  • Now open the fan knob and Keep the fan at least six inches tall. Do it when the gun is away from the same distance from the surface or wall.
  • It’s time to control the material knob. Turn it after raising the gun and aim it to the wall. Hold it in front of the masking paper and pull the trigger.
  • Make a cigar-shaped pattern, and it should be 9 to 10 inches long.

See, it’s simple to make a pattern. Hold on!

Maybe this pattern is not as you need. That means you need to fix it. Look closely at the pattern you made earlier. If the edge has too much density but not the middle of the pattern, it takes control of the air pressure.

It’s happening because the air pressure is too high, and it is spraying too much material at a time. Just screw down the material knob and see the air pressure is reduced.

Don’t get frustrated; it will take some trial and error. Try different levels to adjust the pressure, and you’ll get the proper level for your job. One more thing, don’t forget to use an air dryer. It will keep the line dry.
