How to Avoid Orange Peel When Spray Painting?

Pay attention to the air pressure, try to open it a bit larger, and maintain the proper distance between the spray gun nozzle and the painted surface, typically 10-15 cm. Also, focus on the movement of the spray gun—half overlapping each pass. Below is an introduction to vehicle spray painting: 1. Introduction: Automotive spray painting refers to applying a layer of paint to the car's surface to protect it. Baking paint is commonly used for automotive spray painting. In car manufacturing plants, after the frame and body are welded, the next step is painting. 2. Types: Common types include standard paint, metallic paint, and pearl paint. 3. Composition: Automotive paint generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives.
I pay great attention to avoiding orange peel issues when spray painting cars. Maintaining a stable distance of 10-15 cm with the spray gun—not too close or too far—is crucial. Move the gun at a uniform and slow pace, as if drawing a circle, without rushing. Adjust the air pressure to a moderate range, approximately 1.5 to 2.0 bar; too high and the paint may scatter, too low and it won’t spread evenly. The paint must be diluted to the right consistency—test the flow to ensure it’s not too thick. Start with a thin base coat, wait 3-5 minutes for it to dry completely, then gradually apply thicker layers to avoid buildup. Control the ambient temperature between 18-25°C and keep humidity below 60%, as excessive moisture can cause peeling—choose a cool, windless day for best results. I often practice my spray technique on scrap metal until it feels smooth before working on the actual car. Getting these key details right almost eliminates orange peel, yielding a professional and practical finish.
