Construction proceduresconstruction methodMain materials - auxiliary materialsReference amount
Plain groundThe ground is dry and dust-freeDS-760 Quartz sand0.12-0.18/m2 once
top coatRoll coating or spray coating for UV protection surface coating  
After completion, the overall floor will be bright and clean, with uniform color and no hollowing

Construction proceduresCoating thickness: generally 1mm-3mm. If it exceeds 2mm, it needs to be sandblasted
Personnel can only enter after 24 hours of construction completion, and heavy pressure can only be applied after 72 hours. (Based on 25 * C, the low-temperature opening time needs to be moderately extended)
