Frequently Asked Questions

Why does my HVLP gun sputter?

Your HVLP gun may sputter for various reasons, but one of the most common causes is a loose packing nut. When the packing nut is loose, it allows air to escape from the gun, which can cause the gun to sputter. 

In addition, a loose packing nut can also cause the gun to leak. If you suspect your packing nut is loose, you should tighten it until it is snug. If your gun continues to sputter after tightening the packing nut, you may need to replace the packing.

How long can you leave paint in a HVLP spray gun?

The time frame for leaving paint in an HVLP spray gun can range from 3 days to 3 months. This depends on a few factors, such as the type of paint used and the conditions in which the gun is stored. 

For example, latex paint can usually be stored in the gun for longer than oil-based paint. And if the gun is stored in a cool, dry place, the paint will last longer than stored in a warm, humid environment.

How much pressure does a HVLP gun need?

A high volume, low pressure (HVLP) gun needs less than 10 pounds per square inch (psi) of pressure to atomize the paint. This is because the high volume of air used with this gun helps break up the paint particles into tiny droplets. The low pressure then helps to ensure that these droplets do not bounce off the surface you are painting.

Is paint thinner the same as mineral spirits?

Paint thinner and mineral spirits are both derived from petroleum. Paint thinner is less refined than mineral spirits and thus has a more pungent odor. Paint thinner is also more volatile, which means it evaporates more quickly. 

For these reasons, paint thinner is typically used for cleaning paint brushes and other equipment after painting. Mineral spirits are more refined and thus have a milder odor. They are also less volatile, which makes them ideal for use as a paint thinner.

Can I use acetone instead of mineral spirits?

There are several reasons why mineral spirits cannot replace acetone. 

First, acetone is a much stronger solvent than mineral spirits. This means it can break down more challenging materials, making it ideal for cleaning. 

Secondly, acetone evaporates much faster than mineral spirits. This makes it ideal for use when quick drying is required, such as in the beauty industry. 

Finally, acetone is less likely to leave behind a residue than mineral spirits. This makes it a better choice for use in delicate situations where residue could be an issue.
