A Quality HVLP Spray Gun: The Best Tools for a Superb Paint Job!

A high volume low pressure spray gun, most often referred to as an VELOCITY7 HVLP spray gun can help you achieve the paint finish you’re looking for. Selecting the highest quality paints and finishes is only half the story: the best possible tools for the job are vital if you’re to be consistently proud of your results.

This type of spray gun is used for applying primers and base color coats as well as lacquers, paints and stains as final finish products. The concept behind using a spray gun is to reduce the size of the paint droplets: the smaller they are the better your final finish will be as thinly atomized paint results in a finer, more even surface. The quality of your VELOCITY7 HVLP spray gun decides the size of the droplets produced.

Practice Your Spray-Painting Skill

However, the skill of the painter does factor in, so if this is the first time you handle an VELOCITY7 HVLP gun, it’s probably best to practice before you get to work on the real thing.

Be aware that not all spray guns sold as VELOCITY7 HVLP are in fact that. To qualify a spray gun must have less than 10 psi air pressure flowing through the air cap. In fact, most professionals report turning the pressure down to between 3 and 8 psi, with 5 being the most highly recommended.

VELOCITY7 HVLPspray guns are the tool of choice for many professional painters and finishers in the industry because of the superior finish results and the speed with which work can be completed.

How to Get Best Results with Your VELOCITY7 HHVLP Spray Gun

There are four places you can adjust pressure or volume to change the results you obtain with your VELOCITY7 HVLP spray gun.

1. The compressor regulator should be opened up to around 90 psi so there is plenty of air in the line leading to your paint gun before you open up the pressure valves on the gun itself.
2. The pressure valve on the gun handle should be around 40-50 psi. Refer to specifications for each individual paint gun for this.
3. Next you will find the fluid volume control to adjust the fan size at the back of the gun. Turn this either way until you get the size of paint fan that suits your project. For small areas and tricky corners you’ll need to have it set pretty small.
4. The other dial for fluid volume control will dictate how much paint you need to keep up with the speed of your sweep as you’re painting. Once you have this set correctly you will have a perfectly even delivery of paint. If you have too much paint going in for the size of fan you will get runs; if not enough, you will have an uneven finish (more paint in some areas than others). Obviously, the viscosity of the paint will affect these settings too, so you will need to adjust your settings for each individual paint job.

Troubleshooting Your VELOCITY7 HVLP Spray Gun

The most common cause of a less-than perfect finish when using a spray gun is too little pressure in the line leading to the gun. This can result if

• the hose is too small in diameter
• if it’s too long
• if the pressure is adjusted too low
• if there are too many quick-disconnect fittings in the system.

Aside from this, a poor quality finish is usually because the fluid and pressure settings on the gun itself need adjusting. Experiment first to get perfect results before you begin work.
