When installing SPC stone plastic flooring, the main concerns can be summarized as follows:

First, the installation ground requirements are not up to standard

1. Flatness problem: SPC floor has high requirements for the flatness of the base floor, and the quality of the ground directly affects the construction effect and use performance of SPC floor. The flatness requirement is to measure its deviation within 3mm by using a two-meter stick and a wedge gauge.

2. Dryness problem: The ground must be completely dry, the basic moisture content is less than 8%, and keep the surface dry before construction. If the floor humidity is too high, it may cause deformation or foaming of the floor.

3. Solidity problem: The ground should be solid, and the surface hardness should not be less than 2Mpa. If the ground is too soft or there is sand, the floor may be unstable or damaged.

Second, technical problems in the installation process

1. Insufficient reservation of expansion joints: SPC floor needs to reserve enough expansion joints between the SPC floor and the wall during installation, generally 4-10 mm, to prevent deformation or damage to the floor caused by thermal expansion and cold contraction.

2. Improper installation of latches: The SPC floor is designed with latches. When installing the SPC floor, ensure that the latches are tightly fastened to prevent the floor from tripping or cracking.

3. Improper installation sequence and strength: Install the short side first, and then install the long side to ensure the flatness and no gap of the floor. At the same time, avoid using brute force to press the floor during installation, so as not to damage the floor or lock.

Third, construction environment and management problems

1. Cross construction: there should be no cross construction during the self-leveling construction and the floor pasting, and any other work should ensure that it does not cause damage to the self-leveling and floor.

2. Improper maintenance and maintenance: The floor needs to be properly maintained and maintained after installation to avoid long-term exposure to the sun or being oppressed by heavy objects.

In summary, the most worried about the installation of SPC stone plastic floor is mainly the ground requirements are not up to standard, technical problems in the installation process and construction environment and management problems. Therefore, it is necessary to carefully evaluate the ground conditions before installation, select a professional installation team, and carry out construction and management in strict accordance with the requirements during the installation process.
