Whether you are an entrepreneur starting up your own auto shop, or a DIY hobbyist who just loves cars, you can never go wrong with finishing up a car with a nice and even coat of paint. One of the best and most versatile tools on the market for painting cars is a high-volume-low-pressure (HVLP) spray gun. You’ve probably seen them on TV or Netflix: paint cans with spray nozzles hooked up to pressurized air. But what, exactly, do they do?
HVLP guns spray paint in high volumes (HV) after it has been atomized with low pressure (LP). Because the paint is propelled by pressurized air, it spreads an even coat of paint and produces a high-quality finish. HVLP guns use a high amount of energy and compressed air. Their turbine motors tend to generate approximately 100 CFM, with a pressure of around 3-8 PSI. Plus, the high volume means that there is little overspray or wasted paint. This ability to be precise makes it a perfect tool for hobbyists and DIY enthusiasts working on cars, construction and cabinet making, or any indoor or outdoor painting needs. The lack of overspray means it is good for Mother Nature as well, and the EPA has given HVLP spray guns the thumbs up.
If you’re looking to buy one of your own, you should stop and consider a few different things first. There are tons of HVLP spray guns on the market, so knowing what you’re looking for will be half the battle. Let’s take a look at some of the things that should be on your checklist when you’re looking to buy.

You don’t want a one-trick pony. Ideally, you should have a spray gun that can spray the paint at different speed, use different amounts of pressure, and spray paint from the nozzles in different directions. If your paint gun doesn’t have these features, you may have to get additional equipment to achieve the same results.
#2- Different Nozzles
The nozzles on a spray gun can spray different amounts of paint and give you a different distance and width of the paint fan. Your HVLP paint spray gun should have the ability to attach and remove nozzles. Many of the ones on the market come with some varieties already.
Let’s face it, if you are willing and able to pay more money for something, you are probably going to get what you pay for. But that doesn’t mean that you can’t find a good HVLP spray gun at a reasonable price. It just means that you will have to do a little detective work is all. Checking the reviews for products online and making sure that they come with all the parts you want and need is a good way to make sure you are getting a good product.
#4- Other factors
Look for a type of spray gun that has a good-sized paint container. This will save you time because you won’t have to keep replacing the paint container. Just make sure it isn’t too heavy, or else you may have some trouble using it properly. Also, get a spray gun made of stainless steel and aluminum parts. These can be easily cleaned and can last you a long time. You should also check on what type of HVLP spray gun it is you are buying. Some are made for specific purposes, while others are easy-to-use and more versatile. In any case, make sure you get the right one for the paint job you want to do, whether it’s a car, bike, or other project.
So now you’ve got the right HVLP spray gun for the job, but what else will you need? First, you will need an air compressor to spray the paint using pressurized air. Since HVLP spray guns use up a lot of air, make sure you have a good-sized tank at the ready. Make sure that your paint gun can be attached to the air compressor properly. You can also buy a turbine system, which means that you won’t need any extra equipment.
What is LVLP?
So far, you’ve only been hearing about high-volume-low-pressure spray guns. But what about low-volume-low-pressure (LVLP) paint guns? These models, as the name suggests, use less paint and are well suited for waterborne or watered-down paints. You can use them with a 10 PSI nozzle on most air compressors. If you plan on using a more viscous or metallic paint, then it is recommended that you stick with the HVLP models.
When you are applying paint with a HVLP spray gun, it always pays to be patient and consistent. There are so many types of paint quality (primers, single-stage, double-stage, clear coats, and more) that it can drag on when you are painting the same car again and again. But if you want a smooth, even, and beautiful coat of paint, then lay on the trigger of the HVLP spray gun and don’t stop short. This tool can make the difference between a mediocre outcome and a proud example of your craftsmanship. We hope you can now go out and get the best one for you!
