Why does the PVC floor bulge?
After installing the PVC plastic floor for a period of time, some floors will appear bulging, and it seems that the ground is convex, which affects the appearance. So, what is the reason for the PVC plastic floor to bulge?
●Damp deformation
If the house is uninhabited for a long time, the ventilation is poor and the humidity is heavy, the floor will bulge and expand; the moisture content of the base concrete is too high, and the moisture-proof isolation layer is not sealed and absorbs moisture and expands, although the PVC plastic floor is waterproof floor to a certain extent. Moisture-proof performance, but it is not possible to stay in a humid environment for a long time.
During installation, if there are foreign objects on the ground and they are not cleaned up in time during installation, it will affect the degree of adhesion of the PVC plastic floor to the ground, and the floor will slowly bulge.
Before installing PVC floor, the original ground already has solid wood floor. After the floor is installed, the original floor will swell due to moisture, and the plastic floor will also swell due to the influence of the original solid wood floor.
●There is no expansion joint or the expansion joint is too narrow
When installing the plastic floor, you should leave at least a 1 cm gap as an expansion joint, and then cover it with a skirting line. If there is no suitable expansion joint, the PVC plastic floor will not be able to stretch, and it is easy to be stretched when the room temperature is high. Swell and puff up.
Therefore, when laying the PVC plastic floor, it is necessary to clean up the foreign objects on the ground in time and leave suitable expansion joints. If you find that the PVC plastic floor is bulging after installation, you can compare whether the above mentioned will lead to PVC plastic. The reason for the bulging floor.
