B. Measuring the air humidity in the construction environment should be less than 75%;
C. Measuring the construction environment temperature, should be greater than 0 °C;
D. Measure the flatness of the construction floor;
E. Measure the actual construction area of ​​the construction floor.
Second, the construction of epoxy floor treatment work:
a. Remove the concrete floor and other projections from the original floor;
b. Remove the damp part of the original floor;
c. Fill empty shells from the original floor;
d. Repair the original floor cracked and defective holes;
e. After the ad step is completed, it is polished.
Third, the epoxy floor coating construction process
A. Preliminary work
a. The surface water content of the construction ground shall be less than 8%;
b. The air humidity in the construction environment shall be less than 75%;
c. Measure the construction environment temperature, should be greater than 0 °C;
d. Measure the flatness of the construction floor;

2mm and above epoxy self-leveling
a. Primer
Use a long-haired roller to smash the polyurethane A component and apply it to the floor. After a little drying, part of the larger amount of oil absorption will have a whitening phenomenon, and the coating component should be added.
b. Scrape epoxy mortar
The main agent used in the coating: curing agent: 40-7 quartz sand: 50-00 mesh quartz sand: 270 mesh quartz powder = 3:1:3:3:2 (weight ratio) After mixing evenly into epoxy mortar, use The flat knife scraper is full of scraping and the thickness is controlled to scrape once and the thickness of the epoxy mortar is 1mm, and b steps are repeated until the specified thickness;
c. Putty
After the primer is dry, use the self-leveling main agent: curing agent: quartz powder = 4:1:5 (by weight), stir into the epoxy putty, scrape it off with a scraper, and then point the partially defective holes. Make up
d. Epoxy gravity layer
After the putty is dried, mix it with the self-leveling main agent: hardener=4:1 (weight ratio), stand for 3 minutes and filter with a 60-mesh screen, then apply the epoxy gravity layer and coat it with one side. Bubble drum defoaming.
