Construction Guide

1. The ground tax rate is <8%; >8% requires dehumidification and drying

2. The ground strength is higher than 25mpa. When it is lower than 25mpa, it is necessary to use our company's water-based hardener to improve the ground strength.

3. Thoroughly polish and clean the floor and repair floor defects.

4. The amount of materials used in one construction is less than 2kg/square meter

5. When the thickness exceeds 2mm, use a defoaming roller for defoaming.

6. The maintenance period after construction is completed is 24 hours to 96 hours.
