This article explains professional spray painting techniques used in automotive refinishing, focusing on spray distance, overlap control, and trigger handling to achieve uniform film build and surface quality.
Professional Spray Technique: Distance, Overlap, and Trigger Control Explained
Professional spray technique is essential for achieving consistent finish quality in automotive refinishing. Even with correct gun setup, poor technique leads to defects and rework.
Maintain Correct Spray Distance
Professional painters maintain a consistent spray distance of approximately 15–20 cm. Spraying too close causes runs, while spraying too far results in dry spray and rough texture.
Control Overlap for Uniform Coverage
Industry-standard overlap ranges between 65–75%. Consistent overlap ensures even film build and prevents striping, especially on metallic finishes.
Master Trigger Control
The trigger should be pulled to release air before entering the panel and released before stopping movement. This prevents paint buildup at panel edges.
Adapt Technique to Panel Shape
Professionals adjust body movement rather than wrist angle to maintain correct spray alignment on curved surfaces.
Controlled technique reduces defects, improves efficiency, and delivers predictable refinishing results.
