So I've finally started on my floor after having the wood stacked up by the wall all winter. Bought a moisture meter, the pin type, and the wood was showing very low moisture content, if I was reading it properly. Some of it was showing zero percent. I'm using the glossy white moisture barrier, and a little disgusted with the mill work of the flooring I bought. It's a 5' rustic red oak. So at this point I have a a third of the floor in and noticing some cupping on the board. Thinking maybe too dry when installed and now absorbing moisture? Right now the wood that I have opened up to climatize is showing about 2.5 percent moisture, and my subfloor (plywood) is ranging between 8.5-13. Is that too high a content on sub floor? Or will that be okay since we have the vapor barrier? Is the content too low on the flooring? Any help will be greatly appreciated.
