Before the construction of PVC plastic floor, it is necessary to inspect the ground condition and evaluate the project standard. The following aspects should be done well:
The strength grade of fine stone concrete leveling layer (or cement mortar) is greater than C20. The hardness test result by hardness tester should be that the surface hardness of the floor is not less than 1.2 MPa. Fine stone concrete leveling layer (or cement mortar) shall not be empty, cracked, sand.
2) Ground smoothness
The high and low errors within 2m range are within 3mm (2m long measuring ruler detection).
Before construction, the ground should be dry. The leveling layer of concrete or cement mortar should exceed the final curing period for at least 28 days. The moisture content of the base should be less than 3% by using CNN moisture tester.
Waterproof layer should be made on the wall and floor (the height of the wall on the waterproof layer is not less than 30 cm) where the toilet, washing room and boiling water room may be in contact with water for a long time. The ground elevation of toilet, washing room and boiling water room should be 3-5 cm lower than that of other parts.
On the ground floor of the first floor, the civil engineer (or decorative engineer) should do a good job of damp-proof layer.
5) Height difference at the interface with other materials
The height difference at the junction of other floor materials (carpet, marble, wood floor, floor tile, etc.) should be within minus 4-6 mm. Flax oil floor material laying front door fan bottom to ground seam H (> 10mm).
6) Cross construction
Cross construction is forbidden in floor material construction. Ground material entry construction shall be arranged after all the pre-process has been completed and exited, or before the final painting.
7) Construction period
Ground material construction, each process has a certain period of maintenance, and later construction is more elaborate. In order to ensure the construction quality, it is necessary to ensure sufficient construction period.
