1. The reason for the sound of the drum sound is due to the fixedness of the drum. The main reason is that the number of nails and keels, the board and the nails on the floor are small or the nails are not strong, and sometimes the shrinkage or the glue is unqualified due to the change of the moisture content of the board. To. Therefore, the process of strictly testing the moisture content of the board, the quality of the adhesive, etc. is particularly important. It can only be used after passing the test. The nail should not be too small during installation.
2, the main cause of uneven surface is caused by uneven base layer or deformation of the floor strip. During the construction, apply the level to level the surface of the keel, if it is not flat, adjust the slab. Ventilation slots should be made on the keel. A 10 mm ventilation gap should be left at the edge of the board. The insulation layer material must be dry to prevent the board from getting up after damp. The flatness error of the wooden floor surface should be within 1 mm.
3, the reasons for the lack of strict seams, in addition to the installation is not standardized, the width of the sheet is large and the processing quality is also an important reason.
4, the main reason for the local drum, in addition to the board moisture deformation, as well as the wool board seam is too small or seamless, in use, water pipes and other leaking water caused by wet floor. After the floor is paved, the floor paint should be painted completely. In daily use, it is necessary to prevent water from flowing into the lower part of the floor. It is necessary to clean the surface layer of water in time.
