What to Do About Small Particles on the Paint Surface After Spray Painting?
2 Answers
If the spray paint is not smooth and has a grainy texture, it may be due to an unevenly sanded base layer; the paint layer applied may be too thin, or the working environment may be poor, leading to dust settling on the paint; it could also be caused by improper paint viscosity, resulting in poor spraying effects. For particles after spray painting, the standard treatment is to polish and wax the surface. Here is some relevant information: 1. Reasons for small particles: Generally, there are several causes for this issue—poor base layer preparation, inadequate sanding, low-quality paint, incorrect application methods, or an unclean spray gun. 2. Spray paint (aerosol paint): Typically composed of an aerosol can, valve, contents (paint), and propellant, it is paint processed and pressurized for easy spraying, also known as manual spray paint.
I've encountered the issue of small particles after painting before, mostly due to an unclean painting environment, such as dust or improper spray gun distance causing dust adhesion. To solve it, you can first park the car in a dust-free area, gently sand the particle areas with fine sandpaper, clean thoroughly after smoothing, and then repaint. Before painting, ensure the car surface is free of impurities, the working environment is well-ventilated but avoid windy days, and adjust the spray gun to the correct distance—not too close to prevent paint splatter. The best prevention is to work indoors or in a dedicated paint booth, wearing a mask and gloves for protection. After painting, wait until it's completely dry before checking, ensuring a smooth and durable finish, reducing the need for rework.
