One of the biggest problems of laminate flooring is the plumping at the joint. There are several detailed situations which are as below:
1. Large amount of water falls on the floor surface and enter the support material via locking system. Foe example, lots of water is splashed from a big basin and not cleaned quickly. The part of floor which is near locking system will expand and then push up at the joint. Part of the planks push up in this case as the water only enter part of the floor.
2. The water content of subfloor is too high. The water content of subfloor can’t exceed 12%. If the water content is too high, too much vapour from the subfloor will enter the support material via locking system. Most of the planks push up as the vapour from subfloor is average.
3. The installer use too much power when he press the locking system at the short of one plank into the installed plank. Most probably the problems happens on individual planks.
4. The quality of support material is too bad and its swelling rate is too high. When the air becomes damp, The part of laminate flooring which is near locking system will expand and then push up at the joint.
5. The water from washroom, kitchen or other place enters the bottom of floor from the expansion space between wall and laminate flooring. The plumping problem is more serious when it is near water source as there is more water. |
