1, walk around the floor with sound the reason: (1) Insufficient keel leads to uneven flooring or floor keel expansion after absorption; (2) The floor is too thin to have a rough floor; (3) The spacing of the keel is too large and the floor support is not strong; (4) In the wet season, the floor is too dry. Suggest: (1) The moisture content of the general floor after fumigation will not exceed the standard, and the supporting keel must be selected as a regular product; (2) Laying of the keel is recommended to lay 4 meters of keel under each flat floor, making the support solid; (3) Requirements for laying of wooden keel and wool floor: It shall meet the standards of China Engineering Construction Standardization Association: CECS 191:2005 "Technical Specifications for Wood Flooring Paving Works". 2, deformation warp, corner gap Cause: The floor is not adapted to the indoor environment and the floor is not dry Suggest: (1)Be sure to keep the floor dry before installation. If possible, call for floor delivery 24 hours in advance. Allow the floor to adapt to the room temperature and humidity before paving. (2) Confirm that the foundation is level and the height is less than 3mm/2000mm. Carefully clean it to ensure that the ground is flat and clean. No grain, dust and bumps are required, and the same space must be leveled to a level of 2 cm. (3) The wall should be straight, so as not to cause cracks in the skirting line; drill holes in the wall before installing the skirting board. The spacing between the nails should not exceed half a meter, otherwise the baseboard is not firm; 3, arching Reason: No seam left during installation Suggest: (1) According to the characteristics of different wood species to leave a gap of 8 ~ 12mm, to prevent moisture expansion; (2) It is recommended that each room has its own plate. The room doors at different rooms are separated by metal buckles. If the area is relatively large, every 8 to 10 meters is separated to ease the effects of thermal expansion and contraction. Other installation tips: (1) The room living room floor should be slightly higher than the kitchen floor to prevent moisture deformation; (2) Install the floor as soon as possible into furniture and ventilation. Because the entire space had only the lowest water content of the floor before there was no furniture. All moisture will be absorbed by the floor. After entering the furniture, the water content of the furniture is also low, and the moisture will be removed, which is beneficial to floor maintenance.
