How much pressure does a HVLP gun need?

HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure ( 10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.

How much psi do I need to run a paint gun?

10-15 psi when trigger is pulled for base coat is what most say to set your gun at. Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns.

How much psi should a spray gun have?

No problems spraying that with a respirator with cartridges rated for organic vapours. AFAIK it’s not illegal to spray at home. 2k colour and clear is polyurethane and contains isocyanate.

Are LVLP spray guns any good?

LVLP spray guns are better than HVLP spray guns because they produce few defects. This is because air bubbles can be produced in high volume which can cause a lot of defects. The LVLP uses low pressure and a thin nozzle which allows a low volume of paint to be pushed out of the gun.
