Floor deformation or board surface cracking
Phenomenon: Floor Deformation or Slab Peeling
The crux of the problem: When installing flooring, mulch film should be used first. If the mulch film is not sealed well, the surface moisture will cause the partial floor to swell excessively, resulting in unbalanced expansion of the upper and lower surfaces, and the occurrence of tile buckling and local cracking.
Solution: Surface repairs can be performed for minor surface cracks, and partial replacements can be severe.
The floors are separated from each other
Phenomenon: The floor and floor are separated from each other.
The crux of the problem: 1. Because the floor has the properties of dry shrinkage and swelling, in the northern regions where there is damp weather in summer and in winter, in the winter, the springs used to fix the floor may lose the thrust or the thrust will be insufficient. The amount of expansion of the floor in the summer cannot be restored to the original position, resulting in gaps between the plates; 2. If the concrete floor is not evenly set before installing the floor, it will cause gaps between the floor plates.
Solution:
1. Replace the spring and use a tensioner to reset the floor;
2. After laying the ground, re-lay it.
Floor arching
Phenomenon: Part of the floor is arched, bulging, trampling or floating feeling.
The crux of the problem: 1. Inadequate expansion joints reserved by construction workers lead to arching of the floor; 2. In the space where the length of the room exceeds 8 meters, no transitions or expansion joints are reserved to cause arching during paving.
Solution: 1. Increase the expansion joints around and require that the cutting be neat; 2. The room with a large span needs to install transition buckles at suitable locations.
Cracked or frayed seams at seams
Phenomenon: Cracks or flaking of the paint film occur at the seam between the floor and the floor.
The crux of the problem: 1. During the installation process, striking the plate is uneven or unevenly applied, resulting in localized slight flanking and cracking; 2. Inadequate reserve of expansion gap during installation, slight arching after expansion and extrusion, and local friction caused by walking around Flap.
The solution: minor damage can be repaired with repair wax, severe one-piece replacement.
The floor goes up
Phenomenon: There is abnormal sound on the floor tread.
The crux of the problem: 1. Crude oil ground is uneven, and the uneven surface is not treated in the installation process; 2. The glue is not used in the installation process, or the glue is used in the installation process or the glue is not in the correct position. There is no connection or connection. The effect of fixed seams, resulting in the occurrence of mutual friction between the slots and produce sound; 3. Insufficient space reserved for the floor, or the floor mat is not sealed, resulting in partial or overall arching after the floor expansion, notch up and down to produce Rubbing sound.
Solution:
1. Remove the floor, re-level the ground and then install;
2. After the floor is removed, it is filled with rubber and re-paved;
3. Because the floor mat is not sealed and the floor is slightly deformed, it can be filled with glue and severely deformed to replace the new board.
