Hey, it’s Tony from LearnAutoBodyAndPaint. Today’s topic is HVLP Spray Gun – What is it used for? Pros and Cons With Auto Painting.

There’s a lot of confusion on when to use HVLP and LVLP. Hence, I will now explain the use of High Volume Low Pressure Spray Guns.

HVLP Spray Guns are better than conventional spray guns. The conventional spray guns have a lot of atomization, which means it atomizes your paint really well but with a lot of waste, overspray and have a very inefficient transfer rate.

Transfer rate means the paint getting on to your panels. Consequently, HVLP Spray Guns are created and designed differently to address these concerns.

Here are the pros of HVLP Spray Guns:

– Higher transfer efficiency rate of about 60% to 80%. This means the material coming out of your nozzle to the panel. Conventional Spray Guns have 35% transfer rate.

The Atom Spray Guns have at least 75% transfer efficiency rate so it has low material wastage and low overspray. These are available on Zoolaa as an authorized and only distributor of the brand.

– Reduced material and emissions.

– Uses low pressure to atomize materials while having high transfer efficiency rate.

HVLP spray guns need more air pressure to operate. You will need a bigger compressor. However, it all depends on the size of the project you’re doing.

If you’re doing touch-ups like doing a fender or a quarter panel with a 30-gallon 3 HP compressor, that is fine.

However, it is not recommended to paint an entire car with a 30-gallon compressor. It will need a lot more volume.

The ideal spraying with these spray guns is about 26-28 psi with the trigger pulled. Check out the video as I explain more about the HVLP Spray Guns.

Some of these accessories can be bought on Zoolaa. Check them out!

HVLP Spray Guns are exceptional for base coat. Another question that I also get is if these spray guns can be used for both base coat and clear coat. The answer is absolutely and I do the same thing.

On the other hand, some people get too technical and prefer to use the HVLP Spray Guns only for base coat since it has a great transfer efficiency rate. These spray guns are also great to use for metallics because it atomizes really well.

The recommended tip size for overall car painting, including single stage enamel and even woodwork is 1.3 or 1.4 tip size. I personally like to use the 1.4mm tip size. A 60-gallon or even 80-gallon compressor is great for these spray guns.

To get a really good paint job. It’s just a matter of material coming out, timing, distance with the right pressure. As long as you’re spraying 26-28 psi with base coat, about 5-8 inches between the gun and the panel with a wide open fan and material wide open.
