Recently we installed a laminate floor, and have a scratch on it also. Recently, I happen to see on the QVC Channel, a product, which you are allowed to use on any floor. You may want to look it up. The items QVC number is Item #V17514. It is called Don Asletts Floor Restorer. You may want to look it up. I'm going to look into also. My big question is, will this affect our warranty?
