What Is An HVLP Spray Gun?

Nowadays, HVLP spray guns are getting more popular. The complete form of HVLP is “High Volume Low Pressure.” It’s a process of producing a high volume output using a tiny amount of pressure in simple words. 

HVLP spray guns help do DIY projects and are easy to use for those who try the spray guns for the first time. However, we don’t recommend this for professional jobs because most HVLP is slower than LVLP. 

Moreover, HVLP spray guns use compressed air more than the LVLP and struggle on thicker paintings too. The best feature of HVLP spray guns is it doesn’t let any paint get wasted, and the surface gets all the color.

Now you know what an HVLP spray gun is. But what is an HVLP low cfm spray gun? Well, it is also a usual HVLP spray gun, but it can run in small compressors. Normal HVLP requires a large air compressor, but it doesn’t.

Types Of HVLP Spray Guns

Most commonly, the type of HVLP spray gun is the one that requires air compressors. The other kind is an electrical spray gun. It doesn’t use air, and it makes displacement with the help of a built-in compressor. 

These are also referred to as airless spray guns. Professionals tend to like the spray guns with external air compressors because it provides more benefits.

Low CFM Spray Guns

The outstanding feature of low CFM guns is it uses less air at the cap. The most significant benefit a Low CFM Air Cap Spray Gun provides is reducing the work pressure on your compressor. 

However, there are a few drawbacks too for reducing air consumption. Depending on the gun’s model, the usage of air volume varies. Lower CFM means less effectiveness at atomizing coatings.

Types Of Paints You Can Spray With HVLP Spray Gun

You have this query about what paints you can use when you have the HVLP spray gun. They are as follows.

Automotive Paints

If you are thinking of painting them in your garage and giving it an entirely new look, you must need that HVLP spray gun. 

The chief reason why people like to paint their car using this spray gun is that it’s excellent at thin painting and it never wastes any paint. They do not need much pressure for atomizing thin materials. 

Primers

We often see some old objects have lost their accurate color, and we want them to get their last new look back. But if you directly use the paint using the spray gun, the color will not sit perfectly. 

Therefore before painting the actual color, you need to apply primer color. To bring the best output out of the primer color, you should spray it using the HVLP spray gun to make the color quality even more promising.

Latex

Although latex painting is genuinely thick, we can still use the HVLP spray guns for spraying. 

Of course, you have other better options, but you can do your job with it if you lack money to buy a new better spray gun. It will finish its work fast enough than smaller spray guns like LVLP spray guns. 

Lacquers

It’s tough to paint something with lacquers, especially when there are no right tools available to you. 

Previously people used to paint tints with roller brushes, but nowadays, people use spray guns because they can paint the full-quality color. But if your spray gun is new, you might have to use it for a few months to get an excellent quality color. 

Water Based Paints

Like all the other paints mentioned above, HVLP spray guns are also suitable for painting water-based paints. Still, many people use roller brushes, but this will do the work fine too. 

But this will buy a lot of your valuable time. You don’t want to waste much time in the painting, don’t you? That’s why it’s better to choose the HVLP spray guns over roller brushes for water-based paints too.

How To Set Up HVLP Low CFM Spray Guns?

Setting up an HVLP spray gun does not take much effort. You have to follow the following three ways for setting up your HVLP spray gun;

First Step – Air Supply

HVLP guns require high-volume air to operate correctly. You will see in the directions that what is the minimum CFM your spray needs. 

The pressure produced by the air compressor is not enough. It also needs to create enough pressure constantly. So be sure of having enough cfm capable compressor. 

Set the air compressor so it will put out around 90 psi. Also, set the air pressure at the entrance for air pressure in the gun. You will find small regulators attached to the base of the spray gun with gauges.

Another thing you must need is an air dryer. If you have any oil or water in the airlines, it will do the work. Let us give you a good idea, but a little disposable one on your gun end.

Second Step – Choose The Right Tip For What You Are Spraying

We are talking about a fluid tip. You will probably get a few with the gun. The best little tip is for what you are shooting that will work right. 

The tech sheets for shooting materials will generally have a recommendation for the tip size. We want to let you know the recommended tips for different works. For small jobs, you need 1.0 tips. 

To apply paint or to clear a whole car is required 1.3 or 1.4 tips. These sizes are also acceptable for doing epoxy and sealers. For building primers, depending on how thick you want, 1.8 to 2.3 size tips will be fine. 

Third Step – Final Set-up

Each time you want to use the gun, you have to set it up. Differences in temperature, humidity, and other factors will affect your gunshots. That’s why you must know the right way to set it up. 

Let’s learn the setting up process then. First, you need to tape on the wall a masking paper to test your spray gun. Now it’s time to set pressure on the gun inlet. Use the air regulator you attached with a gauge to the gun. 

Set it with the trigger pulled. Set 50 psi on the meter and start. And then, when you pull the trigger, open it at the point where air volumes stay the same and then stop. The book and air pressure should be set by it. 

Then open the fan controlling knob on all the way. You can then turn it a little down. Now screw the material knob lightly until it properly seats. Unscrew it again for about two turns. 

It’s now ready for the test! Hold the spray gun from the paper at a distance of around 8 or 9 inches. This distance is correct for spraying. 

Now start spraying and see if the gun is working correctly. If it works great, then you have successfully set up the HVLP spray gun.

FAQ’s

How Many CFM Does An HVLP Gun Need?

Spray guns need to use so much air, and providing it more perspective means helping them perform better. However, the lowest CFM you need is 8 CFM to consume the air volume HVLP spray gun. 

Our recommendation is 30 CFM, at least if you want no issues regarding its good atomization and fan pattern changes.

Do You Have To Thin Paint For The HVLP Spray Gun?

You should thin the latex paint at a 10% minimum. In simple words, mix a quarter cup of water with 1 gallon of latex paint. 

However, this is for when you use something else other than an airless sprayer. However, when using an HVLP spray gun, you need to decrease the water percentage even more, from 20% to 30%. 

Can I leave Paint In My Sprayer Overnight?

Yes, you can leave the sprayer overnight but not with pressure instead of into a bucket filled with water. Move the airless cap nut ¾ inches so that it fits appropriately with the intake tube end.
