HVLP Sprayer Troubleshooting   Tips and Guide

HVLP sprayer gun is a powerful tool for painting your room or furniture.  However, like all tools, it can have its own set of problems that you may encounter while using it.

Using an HVLP sprayer may need a bit of practice before you can get the best finish out of it.

Especially if you have not used it before and you do not know how to use it properly, you should try your hands first by spraying it on a rough surface.

For starters, if you find issues when using the sprayer, here are a few troubleshooting tips that can help.

1- HVLP spray gun spit or drip

Spray guns usually spit or drip because their fluid nozzle is not tightened right.

A loose nozzle allows the air to enter the fluid supply outside of the air cap, which results in spitting the paint.

The problem of paint spitting and gun sputtering may also occur if the fluid nozzle or the fluid needle is worn out and needs replacement.

2- Not Getting A Desirable Finish

If your Gravity Feed HVLP Spray Gun is not providing you with a good finish or if you find that the paint appears chunky, uneven, and different on both sides, it may be due to the lack of air or the worn-out air cap.

Make sure that the air vent hole or the hose is not clogged and that you have the correct settings to get the proper air pressure.

3- Air Leaking Around The Sprayer Handle

The leakage of air around the sprayer gun’s handle can be most likely due to the worn-out soft seals.

If you use a quality sprayer, it may have rebuild kits included (or you can buy one from the store). When replaced, soft parts like seals and washers can stop air leakage.

If you want to save on the paint and not want any wastage, you should also ensure that the sprayer is adjusted to the correct settings. Avoid setting the air pressure high; it will spray well without leaks and waste.

4- Not getting any paint sprayed out with the HVLP gun

Remember, if the air vent hole and hose are clogged, you may also face paint delivery issues.

Ensure the sprayer is clean and the paint is thin enough to get sprayed correctly without causing any issues.

In most cases, unclogging a paint sprayer is easy! Simply disassemble your device and place the nozzle of your spray gun into a tub of water.

When ready, blow on the nozzle or use a cotton swab to get the gunk out.  Once the device is clean, reassemble it and get back to work!
