How to Use an LVLP Spray Gun for Automotive Paint
An LVLP spray gun can provide efficient atomisation and controlled application when correctly matched to the coating, compressor and setup. Results depend heavily on preparation, gun adjustment and technique.
Prepare the Workspace
Work in a suitable, clean and well-ventilated area. Wear the protective equipment specified by the coating manufacturer and follow all product safety instructions. Never treat a normal dust mask as adequate protection for hazardous paint vapours.
Set Up the Gun
Follow the spray gun manufacturer's instructions for fluid, fan and air-pressure adjustments. Use the coating manufacturer's recommended viscosity and do not add thinner unless the product instructions allow it.
Spraying Technique
Keep the gun perpendicular to the panel and move at a consistent speed. Use controlled passes with the overlap recommended for the coating system. Practise on a test panel before spraying a visible vehicle panel.
Preparation Matters
Good spraying cannot compensate for poor preparation. Clean, sand and prime the surface as required by the coating system. Our car paint preparation guide covers the preparation stage.
For 2K Coatings
Two-component coatings can present serious exposure hazards. Follow the product's safety data sheet and manufacturer requirements, including appropriate respiratory protection and ventilation. Where the coating system requires professional spray-booth controls, professional application is the safer choice.
