REASONS
- Excessive amount of lacquer in one coat, application of several coats of lacquer with too little intermediate drying, the lacquer is too thick.
- The temperature and air circulation rate in the room are high or the evaporation time is too short.
- Incorrect thinner.
- Wood/substrate humidity, substrate temperature are too low.
- The distance between the spray gun and the workpiece is too small, the viscosity is too high due to the low lacquer temperature.
PREVENTION
- Adjust the application, intermediate drying time, viscosity.
- Follow the instructions for use.
- Lower the temperature and air velocity in the room, extend the drying time by adjusting the conveyor speed.
- Increase the moisture of the wood/substrate, pre-temper the substrate.
- Use the right spraying method, thin the lacquer, increase the lacquer temperature to the prescribed limit.
SOLUTION
- Sand the surface down to the base/substrate.
- Re-apply the lacquer according to the recommendations.
