Method to adjust HVLP spray gun

The HVLP spray gun has a finer spray pattern and is capable of applying less material than a conventional air spray gun.

The pattern is created by varying the distance between the tip and the surface. The tip must be placed slightly above the surface during spraying to achieve adequate atomization.

As stated in the introduction, HVLP stands for high volume/low pressure – this is one reason why they’re known to spray paint smoothly and consistently without bubbling or spattering.

It’s important to get a regulator that’s capable of limiting the amount of air going into the gun so that you can use less pressure and not have any issues with getting paint on the surface you’re currently painting.

While some artists might prefer an HVLP for spraying everything from automotive vehicles, and furniture to even murals because it has a wider spray pattern than other types of guns that are considered “high-pressure” it’s also important to follow manufacturer’s guidelines when it comes to adjusting your spray gun!

Using a high-quality surface with the right paint can ensure that your aerosol will stay put and not leave marks on the walls as you spray. Here is a guide on how to properly adjust air pressure settings in your HVLP spray gun.

Before we begin, make sure a few things are in order. This strategy will make the setup process smooth and easy to manage. You can easily see what this is about by finding out which steps we are going to be following in the next part briefly.

Choose the correct air supply

A spray gun cannot function properly without the right amount of compressed air. It’s crucial to choose a good air supply.

Start by examining your spray gun’s nozzle, it will help you calculate how many Cubic Feet of Air Per Minute are needed for the optimal adjustment of your paint application. This is pretty amazing info to know.

When it comes to air compressors, you have a lot of options. Some are shaped like gun silencers, others look like an accordion and there are even those with the aesthetics of a rain boot!

While there are many differences in design, one thing remains constant – each air compressor has different features that allow it to reach its final pressure rating at certain PSI (pound per square inch).

Many people who own a small business may rent or buy a large machine for their everyday chores such as cleaning driveways, filling tires, or operating power tools.

Other individuals find joy and economical use in owning a smaller, portable one. Either way, choosing the right kind is the trick when it comes down to ensuring your safety benefits and efficiency levels all while saving some hard-earned cash.

Select the right tip size

Alright, make sure that you’re using the regulator for the air pressure alone! If you’ve done that and are prepared to move on to the bit gun itself, make sure that it comes with its own dedicated oil or grease.

Otherwise, if it doesn’t come with one, prepare your own gear box with a small amount of oil and attach it to the weapon before use.

Remember to always wear protective gear best suited to your needs and work environment.

Do you know what the measurement of the tip is on your airbrush? I’ll explain. It’s very important to choose a .1, not .3 or .4, for smaller projects because the other two sizes are for larger projects.

A few more tips: If you’re priming, use a .8 or perhaps even a 2.3 instead. Otherwise, it depends on the stroke that you want to create so make sure to figure out which size would be better suited before starting a job.

Set the gun

After every use, ensure that the gun is in proper setup. I know how important it is to complete the full setup process and not skip a step whenever using your gun. Skip?

But trust me — It’s simple to complete, so follow the instructions below if you don’t believe me! After previously completing all steps of the setup process, remove the safety pin from inside the gun.

From there, twist your gun on and keep it twisted for about 5 seconds until air pressure begins pumping through the system.

Once formed, slowly pull back on the trigger until it reaches full potential. And finally, after pulling back fully on the trigger – now wait one minute before repeating steps 1-3 again (which will simply set up another shot).

  • Tape the wall with masking paper.
  • Set the pressure of the gun and keep the air volume pulled and don’t forget to close the control knob.
  • Open the fan knob and take the fan to six inches tall. Do this when the gun is away from the same distance from the wall.
  • Now control the material knob and turn it after raising the gun then hold it in front of the masking tape and pull the trigger.
  • Make a cigar pattern and it must be 9 to 10 inches long.

I don’t think you’ve quite managed to make any pattern at all. We need to take a look at the gun. Is it twisted around? You did wind some material onto the spool, didn’t you?

How about we just adjust the dial on the side and see what happens? If there’s too much pressure, it pulls too much material out at once and creates one giant blob.

Don’t get frustrated; adjusting the air pressure will be a process of trial and error. We advise you to try different levels to determine which is most appropriate for your level of skin moisture.

Also, don’t forget to use an air dryer. Air dryers will keep the line dry so that it doesn’t clog

Method to adjust spray gun

Adjusting a spray gun is not difficult at all. First, make sure to make the adjustments on a level surface.  The best place to do it is on a flat cement surface outside.

Some things to check before you adjust the gun are: -Make sure the gun is clean. -Make sure the air cap is screwed on securely. 

Make sure the air regulator is set to at least 30 PSI. -Make sure to have a can of gas that is full. -Make sure to have a clean outdoor surface.  

A few things to adjust are: -Make sure the tip is tightened so that it fits snug with the size of the tip. -Make sure the nozzle is tight.

Set the gun about 10 inches away from the surface and spray a straight line. If the line is straight and there are no spits or blobs of paint, adjust the gun until there is a straight line.

Tips from my own experience

  • The right airflow is very important for HVLP spray guns and the pressure should not be less or high, it should be balanced to keep things smooth.
  • Check the thickness of the material to make sure the flow is good.
  • Don’t hold the trigger too long in order to avoid runs.
  • Hold and maintain the gun at the right distance because it is about the method you hold the spray gun.
  • You should test your spray guns on cardboard pieces before starting the project.
  • HVLP spray guns come with different guidelines so follow them carefully because they contain valuable information about HVLP spray guns.

FAQ’s

You just need to set your HVLP spray gun at between 25-30 psi (pounds per square inch). You may also need to make a couple of test adjustments based on the type of finish you’re looking for and the paint you’re using. It’s best to start out at the highest recommended pressure and adjust as you go. #HVLP

To adjust the flow on a spray gun, spray a vertical surface with a fan setting on the spray gun. The drops should be in a uniform pattern and be about the same distance apart. If not, adjust the flow setting on the gun.

Achieving a nice smooth finish with a HVLP sprayer is a matter of controlling your spray pattern. A common mistake is to have the spray pattern too wide, which results in a rough stroke pattern. A slightly narrow spray pattern is better, but the trick is to widen the pattern at the last moment before you reach the object. This way you can achieve a fairly uniform finish with minimal overspray. If you are still struggling with this, consider using an airless sprayer for your next project. These are much more forgiving in their application.

The advantage of using a HVLP spray gun is that you don’t need big air compressor. In fact, a small air compressor will do. The air compressor size you need depends on the pressure you need for your HVLP spray gun. For example, you need about 75-150 PSI for your spray gun. If your air compressor can’t produce this pressure, then you will need a bigger air compressor.

There are a few things that can cause this. #1- The most common reason is that the volume of air is too much, or there is too much pressure behind the air. #2- You may have dirt built up around the tip of your spray gun tip. #3- Check to make sure there is nothing pushing the trigger down while it is not in use. #4- Check to make sure the tips are clean. #5- Clean the air cap.
