Well, we left for Thanksgiving, and came back 4 days later to my son's aquarium constant water change system having leaked on the floor for up to 3 days. We've had the heat up for a couple weeks, and the cupping has gone down considerably. I'm afraid to re-finish too soon, I don't want reverse cupping in a year.
This is our 90 year old 5/16 inch thick oak strip flooring, over fir t and g.
Our undamaged floor in other parts of the house reads 9% moisture content. The damaged floor is about 10.5% on top, 14% in the gaps between the boards.
My neighbor has a floor sander, I'm ready to go anytime.
Anyone have any experience with moisture content? I've refinished many floors, no problem with that part. I've never had the pleasure of dealing with fresh water damage though. Thanks.
