How to Solve the Problem of Paint Spraying with Particles?

[Emiliano]

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.

Encountering particles when spray painting your car at home? I've tried it multiple times and summarized some DIY tips. Most particles are caused by dust or impurities in the paint. Before spraying, clean the garage, close windows to block wind, and wipe the car body clean. Purchase high-quality paint, filter it through a mesh when mixing, adjust the spray gun pressure to a moderate level, and avoid applying thick coats too quickly. If small particles appear after spraying, don't panic—wait for it to dry completely, then gently sand smooth with fine sandpaper and water, followed by a light touch-up spray to cover. Always clean the spray gun immediately after use to prevent nozzle clogging. With careful DIY work and proper environmental control, particles can be reduced by 90%. Save money but don't compromise on quality—choose eco-friendly paint for better health. A final polishing treatment will enhance the appearance.

I can easily handle the particle issue, the key lies in tool maintenance. I clean the spray gun before each painting session, as dust is the main culprit; unclean air or surfaces lead to particle formation. Before spraying, blow dust off the car body and filter impurities when pouring paint into the gun's cup. Adjust the distance and pressure properly during spraying—don't get too close or rush. If particles appear after spraying, let it dry, sand them smooth, then apply a thin touch-up layer. For prevention, maintain the spray gun regularly to avoid old paint residue or clogging. Choose a windless, low-dust environment to minimize hassle. Just a few simple steps can significantly improve the results.
