Core principles: * * Moisture proofing, leaving expansion joints, leveling the ground, and not saving auxiliary materials * *. Floor arching and abnormal noise are mostly installation problems, not the floor itself.<\/p>\n\n\n\n

1\u3001 Preparation before installation (crucial)<\/p>\n\n\n\n

    \n
  1. Ground leveling
    -2-meter ruler, height difference \u2264 2mm; if exceeded, it must be self leveling\/cement mortar leveling. The ground is uneven, and there will be hollowing and creaking sounds when stepping on it later.
    -The ground must be dry: the moisture content of cement mortar ground should be \u2264 10% (floor heating ground should be \u2264 8%), and the ground should not be damp, sandy, or powdery. The sanding ground needs to be solidified first, otherwise the moisture-proof pad will not stick and will accumulate dust.<\/li>\n\n\n\n
  2. The floor must first “adapt to the environment” upon arrival
    Unpack the floor and store it indoors for 48 hours (with the same temperature and humidity as at home) to avoid thermal expansion and contraction, especially for solid wood composites.<\/li>\n\n\n\n
  3. Clean the floor: Sweep away dust and stones. Small sand particles can wear down the back of the floor and make noise when stepped on.<\/li>\n\n\n\n
  4. Doors and windows: During installation, do not open windows for a long time and blow directly to prevent the floor from quickly losing water and shrinking.<\/li>\n<\/ol>\n\n\n\n

    2\u3001 Accessory selection (many businesses secretly reduce costs)<\/p>\n\n\n\n

      \n
    1. Moisture proof pad (floor mat)
      -Reinforced composite: commonly used 2mm thick pearl cotton floor mat; It is recommended to choose a damp proof floor mat with aluminum film on the first floor, and not to lay two layers of mats repeatedly (it will be too soft and make noise when stepped on).
      -Floor heating environment: Special floor heating mats (thermal conductive type) must be used, and thick aluminum film mats are prohibited to obstruct heat dissipation.
      -The joints of the floor mat are sealed with tape, and the wall base is flipped upwards by 5-10cm.<\/li>\n\n\n\n
    2. Closing accessories: skirting board, buckle strip (door strip). Priority given to the same color; The entrance position must be separated by a buckle.<\/li>\n<\/ol>\n\n\n\n

      3\u3001 Laying construction details (top priority)<\/p>\n\n\n\n

        \n
      1. Expansion joints (the easiest to overlook! The number one reason for arching)
        -Surrounding the floor against the wall: Leave 8-12mm expansion joints, which will be covered by the skirting board and cannot withstand the wall.
        -Rooms and corridors with a total length greater than 8 meters should be disconnected and equipped with expansion joints in the middle.
        -Expansion joints should be reserved at the entrance, at the bottom of the wardrobe, and around the pillars, and should not be forcefully plugged in.<\/li>\n\n\n\n
      2. Laying direction
        Generally, following the direction of natural light (the light coming in from the window) creates a visually pleasing effect; You can also follow the long side of the room.<\/li>\n\n\n\n
      3. Splicing (locking the floor)
        The lock buckle should be tightened, and there should be no gaps between the boards, nor should it be forcefully knocked or squeezed; Forcefully squeeze tightly, and arch directly after being heated and dampened.
        The height difference between the boards cannot be clearly felt by the naked eye.<\/li>\n\n\n\n
      4. Entrance and exit positions
        The floor between two rooms must be disconnected and equipped with metal buckle strips, and cannot be fully covered! The temperature and humidity vary in different rooms, making it easy for the bunk beds to arch.<\/li>\n\n\n\n
      5. Under the wardrobe\/fixed cabinet
        Suggestion: Do not lay a floor under the cabinet, the floor should be directly placed at the bottom of the cabinet.
        If it is necessary to lay: expansion joints must be left between the cabinet and the floor. If the cabinet presses down on the floor, the floor will not expand and will definitely bulge.<\/li>\n<\/ol>\n\n\n\n

        4\u3001 Additional requirements exclusive to underfloor heating (applicable to both solid wood composite and reinforced)<\/p>\n\n\n\n

          \n
        1. Before installation, the underfloor heating system should be equipped with a drying pipe: heat it up to the highest temperature and maintain it for a period of time to dry the cement floor, then cool it down to room temperature before laying the floor.<\/li>\n\n\n\n
        2. Do not turn on underfloor heating within 7 days after laying the floor; Post use: The daily temperature rise should not exceed 5 \u2103, and the maximum ground temperature should be \u2264 28 \u2103.<\/li>\n<\/ol>\n\n\n\n

          5\u3001 Acceptance points (on-site inspection after laying)<\/p>\n\n\n\n

          Step through the entire house and listen for any unusual noises or empty drums;
          2. Check the board surface: no obvious height difference, gaps, or broken edges;
          3. Check if the expansion joints on the wall are reserved, and if the skirting board covers but cannot support the floor;
          4. Install the buckle strips at the entrance and partition positions in place;
          5. Count the remaining flooring (keep a few pieces for later repair and replacement).<\/p>\n\n\n\n

          6\u3001 Common pit avoidance reminders<\/p>\n\n\n\n

          Do not stack two layers of moisture-proof film and asphalt floor mat \u2192 The floor elasticity is too high, and stepping on it makes noise
          The ground was not leveled and was directly laid \u2192 abnormal noise
          Full house paving without expansion joints \u2192 arching due to high temperature and humidity
          Directly lay damp floor \u2192 moldy and bulging floor
          The skirting board is directly pressed against the floor without leaving any gaps \u2192 arching<\/p>","protected":false},"excerpt":{"rendered":"
