What size spray gun is used for multicolor paint?

Spraying multicolor paint requires a spray gun with a 3.0 mm nozzle. Introduction to spray guns: A spray gun is a tool for applying paint, used in surface treatment of products and is a type of coating equipment. It atomizes paint into fine droplets using compressed air, which are then propelled by airflow onto the surface to be painted. The spray gun mainly consists of a spray cap, nozzle, needle valve, and gun body, and requires an external connection to a pneumatic device such as a pressure tank, pressure pot, or pump. Compared to traditional manual brushing, spray guns are more time-efficient, aesthetically pleasing, and 5 to 10 times more efficient. They produce a fine, smooth, and even paint film. Maintenance of spray guns: Before and after each use, add 3 to 4 drops of specialized pneumatic maintenance oil into the tool's air inlet to reduce wear and extend the tool's service life. Ensure the air supply to the tool is dry and free of impurities. Regularly clean, lubricate, and maintain the tool, and replace worn parts promptly.

My years of experience spraying multicolor paint tell me that a nozzle diameter of around 1.4mm is ideal. A larger nozzle like 1.8mm will apply the paint too thickly, wasting material and causing uneven sagging. A smaller 1.2mm nozzle is prone to clogging, especially when the small particles in multicolor paint get stuck. When preparing the paint, adjust the viscosity to a moderate level - using a viscosity cup, aim for a flow time under 20 seconds. If too thick, add thinner but not excessively, or the paint film won't adhere well. Maintain a spraying distance of about 25cm, moving the gun at a steady back-and-forth pace. Too fast and coverage will be incomplete; too slow and buildup occurs. Always test spray on scrap material first to check atomization. Safety is critical - I always wear an N95 mask and goggles with good ventilation to avoid fumes. Clean the gun immediately with acetone after use to prevent dried residue damaging the equipment. Multicolor paint gives great results but requires attention to detail - doing it right the first time saves time and money.

I've sprayed many cars, and a 1.5mm nozzle works great for multi-color paint. Smaller nozzles like 1.0mm cause issues – prone to clogging and producing fine paint mist particles. The 1.5mm delivers even paint flow with good coverage and less waste. Paint dilution is key: follow the manufacturer's ratio strictly – don't randomly add thinner. Adjust viscosity until it sprays smoothly. Maintain 30cm distance from the surface and move at consistent speed to avoid uneven color. Multi-color paint gives brilliant effects, but spraying too thick causes bubbles or clumps. I prefer multiple thin coats for stability. Never skip safety – prioritize ventilation and wear gloves/goggles. Clean the spray gun immediately after use with nozzle cleaner to prevent clogging. Mid-range spray guns perform well – no need for expensive models.

I recommend using a 1.4mm nozzle for the multi-color paint spray gun. The paint has high viscosity, and the 1.4mm nozzle provides fine atomization and even coverage, reducing waste. Before spraying, measure the paint viscosity with a viscosity cup, aiming for a flow time of 18-22 seconds. Set the air pressure to 25psi and maintain a spraying distance of 20cm while moving at a steady speed. Stir the multi-color particles thoroughly before spraying to prevent clogging due to sedimentation. Always wear protective gear during spraying to avoid health risks. Clean the tools immediately after use to maintain performance.
