It has full control of air atomization. It is a very quick and fast-working gun that makes the fluid material flow easily. It is also affordable and can be cleaned easily.

What Are The Main Considerations To Set Up HVLP Gravity Feed Spray Gun?

When you are going to set up HVLP Gravity Feed Spray Gun for spraying paint, keep the following things in mind which are the most important.

  • #1: Air Control; First of all set up the air control of the gun to use it properly. It plays a very vital role in the performance of your gun. When you pull the trigger, try to set the regulator between 25-30 PSI so that you can achieve the proper air pressure for spraying paint.
  • #2: Fluid Control; Secondly, try to fix the fluid that comes out from the needle when you pull the trigger. If you loosen the fluid needle, it will spray more paint causing bubbles, and if you tighten the fluid nozzle, it will stop the paint to come out. So set the fluid nozzle right according to the fluid you are using and the surface you are spraying.
  • #3: Fan Control; Thirdly, it is very important to set the fan in the right position to get the best atomization of paint and fine finishing results. It will control the working speed and leveling of paint on the surface.

Frequently Asked Questions

How Can I Understand The HVLP Gravity Feed Spray Gun?

HVLP Gravity Feed Spray Gun is a typical gun used for getting high output with minor overspray.

It has a better option for fan control and volume control than the conventional pattern. It is also environment friendly and low-cost gun

How Can I Dilute Paint A Gravity Feed Spray Gun?

You can dilute the paint by following the instructions like pouring the chosen paint into the proper bucket, mixing ½ cup of water for each gallon, and checking the thickness level, if the mixed paint flows freely through the strainer, it is ready to use.

Can I Use Paint Thinner To Thin Paint For The Spray Gun?

Yes, Paint thinner can be used for thinning paint before starting the spray. It can reduce the viscosity of the paint and adjust the right level of consistency. In some paint, water is used to thin but in oil-based paint, thinner is the most used solvent.

What Is The Right Pressure To Set The HVLP Spray Gun?

The right pressure for an HVLP spray gun is 28-29 PSI. Most of the HVLP spray guns work at 40 PSI.

Final Thoughts

Technology has made work easier and faster. All the painters, professionals, and newbies use HVLP Gravity Feed Spray Gun to complete their small painting projects. These guns provide the best possible results.

They only need to adjust and set them properly to achieve smooth and even painted surfaces. The users must learn the right way to use and control the fan, air pressure, fluid setup, tip set up, and nozzle size pattern, so the spray guns work properly without creating any unpleasant happening.
