Manual Spray Guns: A Complete Guide to Efficient Spraying Techniques

• Choose the Correct Nozzle and Needle Size: Fine needles (e.g., 0.8mm) are suitable for precise touch-ups, medium (1.2–1.4mm) for car body topcoats, and large (1.8–2.5mm) for primers and high-viscosity materials.
• Adjust Appropriate Air Pressure and Flow: Too high air pressure increases overspray and paint waste; too low may result in poor atomization. Generally, set pressure between 25–35 psi, adjusting based on materials and application.
• Select Suitable Paint and Thinning Ratios: Follow manufacturer recommendations to ensure optimal atomization and adhesion.   
  

• Stable Hand Control: Keep your wrist and forearm steady to ensure straight lines and even thickness.
• Correct Spray Distance and Angle: Maintain around 15–20 cm distance, spraying perpendicular at a 90° angle.
• Overlap Spraying Method: Each pass should overlap the previous one by about 50%.
• Layered Application Strategy: Use multiple light coats rather than one heavy coat.
• Plan Your Painting Sequence: Start with complex areas, then simple ones; edges before centers. 
  

• Automotive Touch-Ups: Masking → Fine needle & medium-low pressure → Overall mist coat.
• Furniture Refinishing: Large needle for primer → Fine needle for details → Topcoat and protective layer.
• Metal Anti-Corrosion Coatings: High-viscosity primer with large needle → Layered spraying.
