I. Environmental Humidity Adjustment Methods
1. Humidification Equipment
Use a humidifier or place a basin of water to increase the environmental humidity to 50%-70%.
In industrial settings, a high-pressure micro-mist humidification system can be used to evenly increase humidity.
2. Enclosed Space Control
Close doors and windows to reduce ventilation, and cover the cans with plastic film to isolate them from airflow.
II. Direct Can Treatment
1. Humidifying Medium Coverage
Cover the can opening with a damp cloth or water-soaked sponge to maintain local humidity through evaporation.
2. Solvent Dilution Method
For water-based paints, add 5%-10% pure water (use a dedicated thinner for oil-based paints) to reduce the paint viscosity and slow down drying.
III. Precautions
High humidity (>80%) may cause the paint surface to whiten; a balance between humidity and drying effect is necessary.
When diluting oil-based paints, fire safety precautions are required, and avoid using solvents containing water.
IV. Recommended Professional Tools
Temperature and humidity sensor: Real-time monitoring and linkage with humidification/dehumidification equipment for precise humidity control.
