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）A: B=1:1 (mass ratio), solvent is not allowed to be added. Before use, pour component B into a mixing bucket and add the same mass of component A by electronic weighing in proportion. Stir thoroughly for 2-3 minutes to prevent damage Uneven mixing at the bottom of the bucket resulted in local non solidification of the floor. Ready to use and prepare, the prepared polyurea coating should be used up within 15 minutes.
2) During construction, first layer apply solvent-free epoxy anti-corrosion sealing primer. After the primer is completely cured, polish the area to ensure inter-layer adhesion
Reason (note: polishing floating dust must be cleaned with a vacuum cleaner). After cleaning and polishing the floating dust, use solvent-free polyurea intermediate coating combination material to mix evenly in proportion
3) Afterwards, pour this combination material onto the floor and scrape it evenly with a trowel (3mm or 5mm trowel can be selected according to thickness requirements).
After 24 hours of curing, the next process can proceed. If the construction interval exceeds 48 hours, a layer of interface agent needs to be applied before construction can proceed. if
4) After curing, if encountering adverse weather such as rain, a layer of interface agent must be applied before proceeding to the next process.
5) Under normal circumstances, the coating film should be cured for at least 7 days after completion of painting to ensure optimal performance of the paint film.
First step: clean the foundation, fill in the gaps
Second Step: Roll primer
Third step: two-component cold polyurea construction
