Q: I have a brand new hardwood floor. Oak. I have a small 16″x16″ section cupping after one month. The installer told me it was due to humidity, but it only occurred in that one small spot throughout the whole condo. Could it be installed wrong in that one spot? Or sealed while there was moisture underneath?
A: It is certainly moisture related. Cupping generally indicates moisture from beneath. So, why is this the case in that specific spot?
