Circular marks on diy sanded floor

Q: We used a sander after we installed our brand new hard wood floor. After the stain was applied and dried, it now shows a circular marker from the sander.

Now that the stain is on and 2 coats of the water based finish, is there any way to fix the marks so they won’t show?

A: I would suggest hiring a professional to do the job over. I understand peoples desire to do it themselves, but honestly, some jobs are not for the novice. Floor sanding, staining and finishing is one of those careers that really requires a period of apprenticeship.
