This is my first time. I have put in a Schon engineered hardwood brazilian cherry floor. My contractor moved the refrigerator over several planks and they now show heavy groove marks. How do I unglue these boards to replace them without having to take up the whole kitchen section. The glue is Elmer's Glue-All (School). The glue has been setting for two days now. Is there some other way to replace these damaged boards? Am I totally screwed or what?

Elmer's glue for a wood floor installation? Never heard of it.
