A scratch in laminate flooring is repaired differently from one in solid wood because the decorative wear layer is thin and should not be sanded like timber. Surface marks can often be disguised with touch-up products; damage through the surface may require plank replacement.
Clean the mark to confirm it is a real scratch
Remove dust and transferred rubber with a cleaner approved for the floor. A scuff mark may disappear without repair; a groove that catches a fingernail has actually damaged the surface.
Use a compatible touch-up product for shallow damage
Laminate touch-up markers, waxes, or repair fillers can match color and reduce contrast. Test the shade in an inconspicuous area and use a small amount so the repair does not become more noticeable than the scratch.
Do not sand the decorative layer
Sanding can quickly cut through the printed design and leave a permanent dull patch. Do not use abrasive refinishing methods intended for solid wood unless the laminate manufacturer explicitly approves them.
Replace the plank when damage goes through the surface
A broken corner, swelling, or a deep groove that exposes the core cannot be durably fixed with color alone. If spare pieces are available and the flooring system allows it, replacing the plank is usually the cleanest repair.
