We just installed new laminate flooring and withing 1 week this appeared: Whatever it is it isn't deep at all because I can just about feel it with my finger tips. I tried touching it up with acetone but that didn't help at all. I can't imagine what this could be from because we are being really careful until we get some area rugs. We are going to get the Quick Step Fix Kit http://us.quick-step.com/installation-and-care/cleaning-maintenance?tab=4 and try and touch it up but before that does anyone have a suggestion on how to take care of this? Perhaps a good was we should apply the repair kit?
