None of us can answer. Have a local hardwood floor man check. It
has to do with how much material is left before getting into the
tongues. Most floors can be sanded 3 times, again depending on
how heavy each sanding has been.

Be VERY cautious about staining the floor dark. Make sure you go
see several full rooms somewhere with a dark stain. It is
decision from which you cannot recover. I've known several people
to regret the decision.

How is hardwood flooring fastened down over a concrete slab.
This is the real oak that is then sanded and finished.

If an oak floor, such as the above, has been refinished once,
can it be sanded and refinished again for a third go-round?

If a natural colored oak floor that has been refinished
previously is sanded out, can it be stained a darker color?

Thank you in advance.
