Packing
A: 220kg B: 210kg
Storage
To preserve quality, store this product in a cool, dry, and well-ventilated indoor warehouse. Maintain a storage period of up to one year for optimal performance.
Construction Conditions
1. Base surface requirements: Ensure the concrete base is meticulously cleaned, evenly repaired, and polished to the required roughness. Completion of concrete curing is essential, with strength reaching at least C25 and moisture content under 8%. Promptly proceed to the next step following base preparation.
2. Environmental temperature and humidity requirements: The construction environment should maintain a temperature between 5~35 ºC, with the base surface temperature at least 5 ºC above the air's dew point. Humidity should be controlled between 30% and 80% for optimal results.
3. Ventilation conditions: Ensure adequate ventilation during construction. Avoid operations during strong winds to maintain product integrity.
Operation Methods and Requirements
Prior to application, thoroughly mix component B of the coating.
A: B=1:1 (volume ratio)
Utilize professional construction teams equipped with specialized spraying equipment for application, ensuring that the material temperature during spraying is maintained between 50~80 ºC for optimal performance.
Typically, the subsequent process can commence 12 hours after painting. However, if the construction interval extends beyond 24 hours, apply an interface agent layer before resuming construction. In cases of adverse weather, such as rain following coating, a layer of interface agent is essential before advancing to the next stage.
Under standard conditions, allow the paint film to cure for at least 7 days post-application to ensure maximum performance and durability. completion of painting to ensure the best performance of the paint film.
