What should be done before pavement of PVC floor?
Many consumers are curious about what to prepare for the pavement of PVC flooring. In fact, the ground condition is the most important. Since the thickness of the commonly used indoor PVC sports floors is generally not more than 5mm and there is no self-supporting capacity, the floor foundation requirements are very high. The quality of the ground affects and determines the efficacy and appearance of PVC flooring.
Floor requirements:
1. Humidity: According to the opinion of the glue manufacturer, the moisture content of the foundation (weight percentage) should be less than 3%. In case of weather or external moisture, the air should be circulated and the surface moisture should be wiped off in a timely manner. The humidity of the construction site should be kept at 20% -75%.
2. Surface hardness: cut the surface quickly with a sharp chisel, and there should be no burst at the intersection.
3. Surface flatness: use a 2 meter ruler to check, the gap should not be greater than 2mm.
4. Surface compactness: The surface should not be too rough and have many pores, and the surface should be hardened for slightly sanded ground.
5. Cracks: No cracks with a width greater than 1.5mm. There must be no empty drums on the surface.
6. Surface cleanliness: Residual substances such as oil stains, waxes, paints, and pigments must be removed.
7. Temperature: The temperature of the laying site should be 15 degrees, not less than 10 degrees. In addition, the horizontal reference should be maintained, and there should be suitable seals at the settlement joints of the building.
