Would it harm the floor if we place a piano (on plywood) onto the newly stained and refinished floor?

Q: We plan to have newly stained and refinished red oak hardwood installed in our kitchen. Would it harm the floor if we place a piano (on plywood) onto the newly stained and refinished floor?

It needs to be moved to work on the living room.. any suggestions?

A: No, that should be fine. I would lay a drop sheet out and then the plywood. Make sure the floor is clean. It is also a good idea to allow the floor finish to fully cure before covering it. Depending on the finish used, this can take anywhere from a few days after the last coat to as much as 4 weeks.
