When you are ready to get some painting jobs done, don’t go with the brush and rollers. Using a paint sprayer will lessen the amount of time needed to paint. There are many paint sprayers on the market, but an HVLP paint gun is a great option for most projects. HVLP stands for high-volume low-pressure.

For the most part, HVLP air caps will not exceed 10 PSI of air flowing through it. The motors produce over 100 CFM at 3-8 PSI. This creates a softer and easier way to control spray than other paint sprayers.

You will experience less overspray with an HVLP paint gun meaning that you waste less paint. In fact, some guns can boast a transfer efficiency rate as high as 85%. HVLP paint spray guns have many uses. They can be used in the automotive field for painting cars. You can use them for the primer, paint and clear coat with ease.

They are also ideal to use if you want to paint your boat. An HVLP sprayer is great to use for painting projects around the house as well. The lower overspray means less mess to clean up, especially when working outside where mistakes could be costly.

If you have small furniture projects that need to be done, this would also work great!

Use it with varnish, lacquer or paint to get the job done quickly and efficiently.

This paint gun doesn’t come with its own filter to help prevent clogging. You can purchase one separately if you choose to. It would’ve also been nice if this gun came with a storage case for when you aren’t painting.

Some users felt that the gun could have had a wider fan pattern, but overall it seemed to do the job for most people. To alleviate any issues with the overall look of the paint job, be sure you practice your spraying to perfect the finish.


I would recommend this HVLP paint gun to anyone looking to complete their own projects. The cost is right and it can be used for multiple projects without purchasing more equipment. It provides a great way to achieve a professional paint job without the expense of hiring a contractor.
