1. The main reason for the sound of empty drums between the wool board and the keel, the wool board and the floor nails is that the number of children is small or the nails are not firmly fixed, and sometimes the shrinkage or the unqualified glue is caused by the change of the moisture content of the board. To. It can only be used after passing the inspection, and the nails should not be too few during installation.
2. The reason for the lax seam is not only the non-standard installation during construction, but also the large width and size error of the plate and the poor processing quality. .
3. Environmental protection tools should be used in the cutting process of the floor to avoid the harm caused by harmful substances.
4. The main reason for the uneven surface is the unevenness of the base layer or the deformation and bulging of the floor strip. During construction, use a spirit level to level the surface of the keel. If it is not level, it should be adjusted with skids in time. There should be ventilation slots on the keel. The material of the thermal insulation and sound insulation layer must be dry to prevent the board from bulging after being damp.
5. The main reasons for the partial warping of the drum are not only the deformation of the board due to moisture, but also the small or seamless seam of the wool board, which is caused by the leakage of water pipes and the wet floor during use. After the floor is installed, the floor paint should be painted with a complete paint film.
