Applying lacquer to a car, whether for repairs or a complete finish, requires careful preparation and application. Here’s a straightforward guide based on common practices and the information from the provided reference:
Preparing for Lacquer Application
Before you even think about spraying, preparation is crucial for a good finish.
- Clean the Area: Make sure the area you intend to lacquer is clean, dry, and free of any dirt, grease, or wax.
- Repair Damage: If you are lacquering over a scratch or chip, ensure that this damage is properly repaired and smoothed out first.
- Masking: Protect surrounding areas that you do not want to lacquer using masking tape and paper.
Lacquer Application Process
Applying lacquer correctly is key to achieving a smooth and durable finish.
- Shake the Aerosol Can: According to the provided information, shake the aerosol lacquer can for at least 2 minutes to ensure the contents are thoroughly mixed. This is important for even distribution of the lacquer and pigment.
- Test Spray: Before applying to the car, test spray on a piece of cardboard or paper to familiarize yourself with the spray pattern and ensure the nozzle is working properly.
- Apply Thin Coats: Apply the lacquer in smooth, even, cross coats. These cross coats are done by spraying horizontally in one pass and then vertically in the next to get good coverage.
- Maintain Distance: Hold the spray can about 250mm (25cm) from the surface you are lacquering. This helps avoid drips and keeps an even application.
- First Coat Drying: Let the first coat dry for approximately 15 minutes before applying another coat, if necessary.
- Multiple Coats: Apply additional coats of lacquer, allowing each coat to dry before applying the next. Use thin coats to avoid runs or drips.
Drying and Finishing
- Drying Time: Let the lacquer dry completely, according to the product specifications and environmental conditions.
- Curing: After the lacquer dries, it may need to cure for a longer period. Check the product instructions for any recommended curing times.
- Optional Polishing: Once fully cured, you can use a polishing compound to achieve an even smoother and glossier final result.
