Storage
Sealed storage of coatings in dry, cool, and well ventilated conditions, avoiding sunlight and rain, and keeping away from sources of fire.
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 ºC, 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
YP686 can be opened for direct construction.
During construction, in order to ensure interlayer adhesion, polishing treatment should be carried out (note: polishing floating dust must be cleaned with a vacuum cleaner). Roll coat solvent-free epoxy sealing primer. After the primer is completely cured, pour YP686 polyurea onto the floor and scrape it evenly with a trowel (3mm or 5mm trowel can be selected according to thickness requirements). After curing, proceed to the next process. Curing at room temperature for 12 hours, 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 optimal performance of the paint film.
