Just like many other flooring out there, laminate has a down side also. I have personally experienced this lately. When my a/c unit decided to leak water all over my laminate flooring. You see, when water interacts with the fiber board, which is the core of laminate flooring, it destroys the flooring causing the top layer to buckle. Small amounts of water on the top of the laminate is okay. Problems start when water reaches under the laminate top layer below into the fiber board. In my case, the water traveled along my concrete slab from the unfinished part of the a/c closet to the bottom side of the laminate floor, instantly destroying my flooring.
