REASONS
- The lacquer is insufficiently levelled (oversized droplets).
- A large temperature difference between the lacquer and the surface.
- Incorrect pressure when lacquering or incorrect distance from the surface.
- The temperature and air velocity in the room are too high.
- Drops of lacquer that are too dry fall onto the workpiece.
PREVENTION
- Lower the viscosity, increase the pressure, and use a smaller nozzle.
- Check and adjust the temperature difference between the lacquer and the surface.
- Set the spray gun and follow the instructions.
- Lower the temperature and air circulation rate.
- Use a slow thinner, check the distance between the workpiece and the spray gun, increase the flow of the lacquer.
SOLUTION
- Sand the surface down to the base/substrate.
- Re-apply the lacquer according to the recommendations.
