Storage
This product should be stored in a cool, dry, ventilated indoor warehouse with a storage period of one year.
Construction Conditions
1. Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible.
2. Environmental temperature and humidity requirements: The construction environment temperature should be between 5~35 ºC, and the base surface temperature should be at least 5 ºC higher than the air dew point; The humidity range should be between 30% and 80%.
3. Ventilation conditions: Ventilation should be maintained during construction, but construction should not be carried out when there is strong wind.
Operation Methods and Requirements
Mix component B of the coating evenly before use
A: B=1:1 (volume ratio)
Professional construction teams must use professional spraying equipment for construction, and the material temperature during spraying should be controlled between 50~80 ºC.
In general, the next process can be carried out after 12 hours of painting. If the construction interval exceeds 24 hours, a layer of interface agent needs to be applied before construction can proceed. If encountering adverse weather such as rain after coating, a layer of interface agent must be applied before proceeding to the next process.
Under normal circumstances, the paint film should be cured for at least 7 days after completion of painting to ensure the best performance of the paint film.
