First, the preparation before laying
1. Ground flatness measurement: Measure the flatness of the ground and decide whether to do ground leveling.
1) The floor area laid is within 50 square meters, the ground flatness error is more than 2 centimeters or more than 2 millimeters. It is recommended that the ground leveling be handled.
2) The installation height of the floor differs from the height of other ground 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 to be used for local leveling treatment.
4) After ground leveling, the local flatness error must not exceed 3 mm.
2. Ground moisture 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 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 accessories: the proposed installation direction of the floor, skirting board, sliding doors, floor-to-ceiling windows, low cabinets, platforms, stairs and other parts of the specific installation method for the owner to choose to 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.
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 - solid wood flooring moisture content and the local equilibrium moisture content is close.
2, the appearance of the floor quality - paint film quality and wear resistance, cracks, processing ripples, etc.;
