Need some expertise from the pros here! I'm not sure even where to start, but I'm looking for "what next" and/or "solution" and/or just "what to expect". THANK YOU IN ADVANCE for bearing with me on my novel below. Trying to give background so hopefully it helps with the feedback.

Wood floor guys are installing new solid 1/2" white oak hardwood floors over concrete. They told us they used a special moisture barrier adhering glue (it was an orange compound). They "ran out of wood" and I busted them loading in new wood into the house and laying it immediately without acclimating. It gets better, the "new" batch of wood is red oak instead of white oak. It stains differently and so we asked them to rip it all back up. They purchase thicker white oak wood floors and sand it down to match the current thickness of the floor, but I noticed that they didn't use the same orange adhesive to glue down the floor. The one they use this time around is grey. They seal the floor with Bona HighTraffic HD. This morning the general contractor came in and noticed the floor was "uneven". They measured the moisture and the original wood that was acclimated, that reads at an 8. The new section that they just replaced reads at a 12. My husband also notices "cupping" happening all over the place. They're saying that we just wait for moisture to go down in new section (even though it's still sealed). And that it was just a bad sanding job and we resand to level it out.

Will this fix our issue?
Without removing the HighTraffic HD sealant, will our floors ever get back to an acceptable moisture reading?
What types of problems will we have later?
What would you be your suggestion on how to move fwd?

Sorry youy have had these problems with your floor contractor. Even with finish on your floor the moisture content of the wood will slowly acclimate to the humidity level in your house. It will take longer with finish on the floor, but it will acclimate.Cupping may be the result of not allowing enough time to acclimate before the floor was laid, and the flooring swelled after it was laid because the wood picked up moisture out of the air. The 12 percent wood may be at the right moisture content for your area and could be stable. The cupping will probably never flatten out and would need to be sanded flat again after it is acclimated, if this is the problem. Time will tell. With a wet bulb/ dry bulb hygrometer you should be able to tell what moisture content the wood will have after it has acclimated to your conditions using a table that predicts the wood shrink/swell.
