their is NO laminate hardwood floors ,
it is either engineer hardwood floor (first layer is solid wood,attached to layers of plywood) this can only be refinished.,or filled with colored wood filler,or replace the scrached planks with new planks.
IF it is laminate floor (man made hard serfece planks,looks like hardwood )
you can call the factory or your local sepplier and order a repair kit for deep scrathes (its epoxy colored putty filler ).
my advice to you is to replace the scratched planks by professional person..
