Packing
A: 220kg B: 210kg
Storage
Store this product in a cool, dry, and well-ventilated indoor warehouse, with a shelf life of up to one year, ensuring optimal quality and performance.
Construction Conditions
1. Base surface requirements: Ensure the concrete base is spotless, leveled, and polished to specified roughness. Complete the concrete curing with a strength of C25 or higher, and moisture content below 8%. Following base surface preparation, proceed swiftly to the next phase.
2. Environmental temperature and humidity requirements: The construction environment must maintain a temperature between 5~35 ºC, with the base surface retaining at least a 5 ºC advantage over the air dew point; humidity should range from 30% to 80% for optimal conditions.
3. Ventilation conditions: Proper ventilation is crucial during construction; however, avoid proceeding in conditions of strong wind to maintain quality.
Operation Methods and Requirements
Ensure thorough mixing of component B before use, to guarantee a uniform composition.
A: B=1:1 (volume ratio)
Utilize professional construction teams equipped with advanced spraying technology for the task, maintaining material temperature within a 50~80 ºC range for ideal application.
Typically, subsequent processes can commence 12 hours post-painting. Should the construction interval exceed 24 hours, a layer of interface agent is required before resuming. In case of adverse weather like rain, apply an interface agent layer before continuing to subsequent stages.
Under standard conditions, allow the paint film to cure for at least 7 days post-application to ensure optimal performance and durability. completion of painting to ensure the best performance of the paint film.
