What size air compressor do I need for HVLP?

A gun that uses 15 CFM of air doesn’t need a compressor that will produce that much air as long as you have a tank large enough to hold enough reserve air to get you around the car. I usually recommend that you use a compressor that has a minimum of 60 gallon tank and produces around 13 CFM.

Can you spray latex paint with a HVLP gun?

HVLP systems are not designed to spray heavier bodied latex paint. … The pressurized cup allows the paint to be pushed to the fluid nozzle because of the added pressure behind the paint. If you look at most professional airless paint sprayers designed for latex paint, they are actually pumps, and use no air.

What causes orange peel HVLP?

The most common cause of orange peel is an imbalance between the viscosity of the finish and the amount of air atomizing the liquid as it exits the gun. The thicker the liquid, the more air that is required; the thinner, the less air needed. So the obvious fix is to increase the air pressure or thin the material.
