Conventional spray guns are versatile and can apply various finishes, including paints, varnishes, lacquers, stains, primers, and specialty coatings.

The appropriate nozzle size depends on the viscosity and thickness of the coating being applied. Thinner coatings require smaller nozzles, while thicker coatings require larger nozzles to achieve proper atomization.

Gravity-feed spray guns have the paint reservoir located above the gun, utilizing gravity to feed the paint. Siphon-feed spray guns have the reservoir below the gun, relying on suction to draw the paint up into the gun.

Regular maintenance is crucial for optimal performance. Clean the spray gun thoroughly after each use, lubricate moving parts, and store it properly to prevent clogging and ensure longevity.
