Spraying single component 1K silver paint to repair car defect areas requires some skills and steps to ensure a smooth surface, uniform color, and good gloss. Here are the general steps:
1. Car surface preparation:
- Clean the surface: Use degreaser or other cleaners to ensure that the surface is free of grease, dust and other impurities.
- Sand the surface: Use fine sandpaper (usually P800 to P1000) to sand the surface to make it flat and smooth, and provide good adhesion for the silver paint layer.
- Masking: Use masking paper and tape to cover the areas that do not need to be sprayed to prevent paint from splashing on other parts.
2. Primer spraying:
- It is recommended to spray layer of primer first to enhance the adhesion and uniformity of the silver paint.
- Spray the primers evenly and wait for it to dry completely.
3. Silver paint preparation:
- Mix the silver paint thoroughly to evenly distribute the silver powder particles.
- Add appropriate diluent /thinner according to the paint manufacturer's technical instructions to adjust the viscosity of the spray.
4. Spraying silver paint:
- Spray gun settings: Set the air pressure and nozzle diameter.
- Spraying process:
1. Keep the spray gun about 15-20 cm away from the auto body surface, to prevent the paint from being too thick or dripping.
2. Start from one direction, move the spray gun evenly, and spray in a "cross" manner, which means spraying the first layer horizontally and the second layer vertically.
3. Spray thin layers in multiple times, leaving time for the paint to evaporate between each spray, until the silver paint is completely covered and shows a uniform effect. After spraying, carefully check whether the silver color is evenly distributed. If there is any unevenness, you can spray it locally.
5. Spraying varnish layer:
- After the silver paint layers dry, spray varnish to protect the silver paint surface and increase the gloss.
- The varnish also needs to be sprayed in a thin layer to ensure a smooth surface.
6. Drying and polishing:
- Allow the painted surface to dry fully.
- After it is completely dry, you can polish it if you need a higher gloss or to repair minor flaws.
#Note:
- Ensure the work area is well ventilated and avoid spraying in an environment with excessive humidity.
- Wear appropriate protective equipment such as masks and gloves when spraying to prevent inhalation of harmful gases and direct contact with skin.
