Scraper scrapes off finish in layers

Q: Two weeks ago I had my hardwood floor refinished. We moved the furniture too soon and caused damage. The contractor who finished the floor is coming back to refinish; however, now we can take a scraper and all the finish scrapes off in layers. Is this normal? Has the floor not cured? Will it eventually harden?

This is one room and there were four others done at the same time.

A: Difficult to say if he has failed to gain adhesion between coats or if he applied the finish in too thick a film. Many finishes have a spread rate of 500 feet per gallon.
