During Application

• Each coating layer should not exceed 0.5mm in thickness. Apply the next layer only after the previous one has fully dried and cured. Repeat the process until the required thickness is achieved (recommended minimum: 1mm).

• If the coating becomes too viscous or slightly hardened, add a small amount of clean water to adjust. The amount of water should not exceed 10% of the coating weight. Avoid over-thinning, as it may affect adhesion and coating performance.

• For additional surface protection or improved appearance, a water-based waterproof coating can be applied on top of the finished layer.

After Application

• After finishing the coating, allow natural ventilation for drying. If the humidity is high, use a dehumidifier to accelerate drying and improve adhesion.

• Store the product in a cool, shaded place, avoiding freezing and direct sunlight. Make sure to seal the container tightly after use to prevent hardening.

• The surface drying time is approximately 4 hours, and full curing requires about 24 hours. Ensure adequate drying time before proceeding with the next step or use.
