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 environmental temperature at the construction site should be above 5 ℃, and construction can only be carried out when the relative humidity is less than 85%
3）Ventilation conditions: Ventilation should be maintained during construction.
Operation methods and requirements
1.Part A and Part B are stirred evenly according to the ratio of 5:1, and the appropriate proportion of catalyst is added according to the different temperature and humidity.
2.During construction, in order to ensure the adhesion between layers, sanding is performed (Note: sanding floating dust must be cleaned with a vacuum cleaner). Roll on solventless epoxy sealing primer. After the primer is completely cured, pour the uniform mixture of Part A and Part B onto the floor, scrape it evenly with a trowel (3mm or 5mm bread knife can be used according to the thickness), and proceed to the next process after curing. It is completely cured in 18 hours at normal temperature. If there is bad weather such as rain after painting, an interface agent must be painted before the next process.
