First, the ratio
 The bottom layer is mainly composed of QD-02 or QD-A: QD-B=4:1
Middle layer: Silicon Pu Elastic Layer
Upper layer: surface layer Q3041A/B (4:1) SQM-A/B (13.5:1)
Second, the process
1. Basic ground treatment, including removing debris, ground grinding, handling expansion joints, and finding equality.
2. According to the dosage of 0.15kg/m2, evenly spray or spray the primer evenly on the ground in the case of drying the cement floor to achieve the state of no film formation on the ground.
3. After the basic curing of the bottom layer (can be applied by others), use a tooth scraper to scrape the silicone elastic layer of the PU, about 1-2MM each time. The next layer is not sticky and can be used for the next layer of construction.
4. After the construction of the intermediate elastic layer is completed, sanding is carried out without sticking hands, and then the surface layer is constructed according to the amount of 0.2 KG/m2.
Third, matters needing attention
1. Minimize the construction time between each floor, depending on the construction weather and construction conditions on site. If the interval process needs to be increased in cleaning and grinding, the adhesion of the material can be ensured.
2. The surface must be cleaned before each process in the construction process.

3. After the construction of the site is completed, it must be maintained for 5 days before being put into use.
