Will this product help reduce or hide scratches in a large area without damaging the laminate floor?

ScratchAway is manufactured for hiding or masking scratches and would be able to cover a large area, however it is not a permanent fix for scratches. Large, worn, scratched laminate floors sometimes will benefit more from a “refresher” topcoat product. Whereas topcoats are a big project to apply (you have to remove furniture and strip/prep the flooring surface), they are not a permanent fix. But they do last longer than ScratchAway. ScratchAway works great for localized areas and only takes seconds to apply.
