1. Control the humidity of the storage environment: Place paint cans in a cool, dry, and well-ventilated area, maintaining an ambient humidity between 40% and 80%. Avoid damp basements and corners near water sources. If necessary, use a dehumidifier to reduce humidity.
2. Physical isolation for moisture prevention: Elevate the cans by at least 10 cm and place them on a wooden tray or shelf to prevent direct contact with the ground and avoid contact with moisture from the ground.
3. Sealing protection: Tightly tighten the caps of completely dry empty cans and seal the edges with plastic wrap or tape to reduce airflow and prevent moisture from entering and condensing inside.
4. Auxiliary moisture absorption measures: Place desiccants, activated carbon, or quicklime packets in the storage area to absorb excess moisture from the surrounding environment and reduce the humidity of the local space.
