Hi! First of all, my apologies if this has already been covered. I looked in Wiki, but couldn't find it (maybe because I'm a luddite!). We have hardwood floors in our home that are just under a year old. We had a flood under our fridge while we were away which caused the peeling away of the polyurethane and the stain leaving the light maple exposed in patches on some of the boards. We understand this. However, the same type of peeling/flaking is happening in other areas of the house where there is no exposure to moisture whatsoever. Could someone please educate us as to why this is happening and what we can do about it? Any help would be appreciated. Thanks!
