1. When operating the spray gun, ensure that the nozzle's centerline is perfectly perpendicular to the surface being coated. The spray gun should move in a straight, parallel motion along the surface and must not be tilted. Maintain a steady and consistent speed while spraying to achieve an even finish.
2. The distance between the spray gun and the surface should be appropriate. Based on your air pressure settings, it's recommended to keep the spray distance between 400 mm and 600 mm for optimal coverage and paint distribution.
3. The paint consistency used for spraying should be moderate—not too thick or too thin. Before starting large-scale spraying, test the paint’s consistency to ensure it meets the design specifications. Adjust the viscosity if necessary before proceeding with the main application.
4. For coatings containing coarse fillers or mica flakes, maintain the air pressure between 0.4 MPa and 0.8 MPa. For other types of coatings, conduct a test spray during the initial stage to determine the ideal air pressure for the best results.
5. Spraying should be done continuously in one go without interruption. Try to complete one section at a time, then take a break before moving on to the next area. This helps maintain a uniform appearance and prevents lap marks.
6. If you notice issues like uneven thickness, color variation, or exposed seams, wait until the top layer is mostly dry and apply a thin, even coat to cover the imperfections. In cases of severe defects, remove the affected areas, clean them thoroughly, and re-spray for a better finish.
7. When working indoors, it's best to start by spraying the walls first. After the initial coat, allow it to dry for about 2 hours before applying the second coat. For exterior walls, two coats are usually sufficient, but for a more professional finish, a third coat can be applied after the second has dried.
By following these guidelines, you can ensure a smooth, even, and durable coating that meets quality standards. Always check the manufacturer's recommendations for specific paint types and conditions, and practice on a small area before full application.
