First, the preparation before laying

1. Ground flatness measurement: Measure the flatness of the ground and agree with the owner whether ground leveling should be done.
1) The floor area laid is within 50 square meters, and the ground flatness error is more than 2 centimeters or more than 2 millimeters in total. Ground leveling is recommended.
2) The installation height of the floor differs from the height of other floor materials by more than 5 mm. It is recommended that the floor be leveled.
3) If the flatness error is large or the height difference from other ground materials is large, it is recommended to use a cement mortar for overall leveling. Otherwise, only the waterproof cement-mixed cement mortar is required for local leveling treatment.
4) After ground leveling, the local flatness error must not exceed 3 mm.

2. Ground Humidity Measurement: Use the electromagnetic wave type moisture content measuring instrument to measure the humidity of the ground, one test point every 1.5 to 2 meters; the local key measurement of the construction of the mixed mud mortar in the early stage. The humidity on the ground is large. It is recommended to delay the installation period, add moisture-proof mats or make the floor waterproof.

3. Determine the installation method and calculate the amount of auxiliary materials: Propose specific installation methods for floor installation orientation, skirting board, sliding door, floor-to-ceiling window, low cabinet, floor, stairs, etc., for the owner to choose and determine. If the owner’s special requirements and technical requirements are inconsistent, special instructions signed by the owner are required.

4. Measure the actual area, paint the grass to indicate the size of each part, and calculate the actual floor and accessories used.

5. Sign the contract with the owner to determine the model and model of the purchased product.

Second, the floor to the scene of the open inspection

1. The moisture content of the floor - the solid wood floor moisture content is close to the local equilibrium moisture content.
2. The appearance quality of the floor - paint quality and wear resistance, cracks, processing ripples, etc.;
3. The main dimensions and deviations of the floor - length, width, thickness, etc.;
4. The deviation of the shape of the floor - Assembled from the seam, the assembly height difference and warpage.

Third, the choice of floor color

Solid wood flooring is a natural material and chromatic aberration is normal. Through manual selection and adjustment, the transition can be natural, beautiful, lively and full of vitality.
1. For grades with relatively small color differences, do not grade and adjust directly when laying.
2. For wood with large color difference, it can be divided into deep and shallow categories. Different shades can be installed in different areas or in different shades;
3. In the same color floor installation, in principle, the chord board and the radial cutting board should also be laid.

Fourth, the laying of keel requirements

1. According to the length of the floor, determine the spacing of the keel; the spacing of the keel should not be too large.
2. According to the length of the laying floor, a reference line 300mm from the wall to ensure that the installation position of the keel and the reference line at a right angle of 90 degrees.
3. Determine the 2-3 keels as a benchmark, and adjust the height between them and other ground materials to make the transition natural and beautiful. Strictly control the flatness of the upper surface of the keel.
4. Use a wooden wedge or other hard material to lift the suspended keel; use a dragon king plastic tyrant or styrofoam to secure the wooden wedge and keel, and fill the suspended part of the keel.

Fifth, floor laying requirements

1. Use a wooden wedge between the floor and the wall to ensure that the floor is 8-12 mm from the wall.
2. After laying the first two rows of floorboards, straighten the cords; during the laying process, always straighten the cords to ensure the laying quality.
3. To divide by room or area, add a transition (expansion joint) to prevent the floor from arching.
4. Consciously adjust the color of the floor to make it natural.
5. The skirting board is tightly attached and securely mounted.

Sixth, on-site cleaning and floor waxing

Seven, the acceptance of the floor

VIII. Owners fill in their opinions and suggestions on pavement
