PVC plastic floor may become bulging after paving or completing. Most people are first looking for problems with the PVC floor itself, but ignore the factors in other links. The editor of Dashang Industrial will talk about

To avoid PVC laying the floor, you can make preparations in advance. The intact newly unfolded PVC floor is laid on a smooth, clean and dry floor (no glue scraping); the ambient temperature is maintained at 20℃-38℃, and the relative humidity of the air is not greater than 75%; leave it for more than 24 hours.
In addition, the main reasons for PVC floor bulge are foundation, auxiliary material selection, climate, temperature, construction control, etc. PVC floor bulging problems can generally be divided into the following reasons.
1. self-leveling problem
self-leveling does not dry thoroughly, PVC will inevitably bulge the floor in the future (usually dry for seven days); according to international standards, the ground needs to be polished again to ensure the flatness of the ground. The non-polishing, uneven or gray self-leveling bulge the floor, which can also easily lead to floor bulge.
2. The glue is not dry in place
PVC During the sports floor glue bonding construction, whether the glue is dry will also affect whether the floor is bulging. Generally speaking, the glue is not sticky and then placed on the board for the best construction time.
3. Uneven flooring is welded on the floor
Inadequate flooring will lead to uneven flooring welding. In the long run, the flooring is easy to weld and will also lead to floor bulge.
4. Cement floor expansion joint
Cement floor expansion joint will also cause the accumulation of water vapor on the ground, which will cause long-term moisture and bulging floors.
5. The selection of auxiliary materials is incorrect. The auxiliary materials are very important in different PVC processes, different specifications, and different grades of floor construction. The requirements for auxiliary materials of PVC floors are different. Different places of use, different sites and environments, different seasons and climates are different. For example, cement floors should be constructed with double-sided adhesive to ensure a firmer construction; PVC sports floors should not be used for double-sided adhesive, but single-sided adhesive should be used for bonding. The reason is that the wooden floor itself is most likely to be damp due to thermal expansion and contraction. The bonding of double-sided adhesive will cause PVC glue, displacement, and bulging to appear on sports floor .
6. Improper construction
Improper construction can also lead to the most direct factors that affect the floor bulge. Once the floor is not straightened during the floor construction process, the board is uneven, and there are subtle cracks or misalignment, the hidden dangers of floor drums will be buried. After long-term exercise, floor drums will appear sooner or later.
7. The exhaust is not in place
Take the badminton court as an example. Because the badminton net column is heavy, long-term vigorous exercise will cause the exercise areas on both sides of the floor to slightly bulge towards the middle net column area, and accumulate air over time, which will also cause the floor to bulge under the action of air. In this case, the floor on one side of the mesh column can be flipped, the floor can be supported by a cylinder, straightened by an exhaust overnight, and then laid normally.
