Following any spray painting job with an air spray gun being either conventional, HVLP, or LVLP type, the following cleaning and basic disassembly and reassembly steps are usually recommended.
Remove any remaining paint from the pot and to save solvent spray gun pot could be wiped clean with paper towel which can be easily discarded once the paint is dried. Pour a small amount of solvent into the pot and swish around to clean then spray the solvent through the gun. Add additional solvent as required until no further colour is spraying from the gun.
This general guide to using an air paint spray gun can apply to conventional air paint spray guns, HVLP air paint spray guns and LVLP air paint spray guns in gravity feed, suction or pressure feed variants.
The first thing to check is the paint manufacturers technical data sheet which will recommend a fluid nozzle size and often an air paint spray gun type for use with their coating.
The technical data sheet should also specify maximum thinning that is allowed for air paint spray applications.
