Q: Can cupping of laminate floors be caused by using a rubber-like kitchen mat by the sink and dishwasher area?
A: This is an interesting question to ponder. It isn’t having a mat there that is a big problem. However, this is near a water source and in the case of the dishwasher, hot steamy water. If that vents steam and it can get under the mat it would be trapped, and that would be a problem.by
