How to Solve the Problem of Paint Spraying with Particles?
2 Answers
Solutions for paint spraying with particles: 1. Clean and wipe the body surface thoroughly; 2. Use a polishing machine with polishing powder for polishing; 3. Apply wax to the car. It is advisable to develop a habit of regular maintenance and pay more attention to paint surface care. Some paint maintenance projects, such as waxing, glaze sealing, coating, and crystal coating, can protect the car paint to a certain extent. Uneven paint spraying with a grainy texture may be due to an unevenly sanded base layer, too thin a paint layer, poor construction environment with dust falling during spraying, or inappropriate paint viscosity leading to poor spraying results. For particles after spraying, the standard treatment is local sanding, followed by repainting after leveling, and then polishing and waxing can be performed.
Paint spray particles are quite annoying, I must say it's a common issue. I've been painting for over ten years, and particles are often caused by too much environmental dust, such as an unclean workshop floor or excessive air movement. Before spraying, you must clean thoroughly, use compressed air to blow off the car body and spray gun, and filter the paint to remove impurities. When spraying, don’t set the pressure too high—keep it between 15-20 psi, maintain a distance of 20 cm, move evenly, and avoid spraying too thick. After spraying, inspect the surface. If the particles are small, wait two days for it to dry, then wet sand with 2000-grit sandpaper and apply a thin coat of paint. If severe, you'll need to respray the entire panel. Prevention is key—regularly clean the spray gun nozzle and install an air filter in the paint booth to save a lot of trouble. Remember to wear safety gear like gloves and a mask.
