A scratch in a wood floor may affect only the finish or cut through to bare wood. The right repair depends on depth and finish type; starting with the least invasive method helps avoid creating a patch more noticeable than the original scratch.
Clean the area before judging depth
Remove dust and soil with the floor’s normal compatible cleaner and let it dry. A gray mark may be surface transfer rather than a true scratch and can disappear without filling or sanding.
Fine finish scratches may be improved without sanding
A manufacturer-recommended touch-up product or compatible maintenance coat may reduce fine finish scratches. Test in an inconspicuous area because a mismatched sheen or color can make the repair stand out.
Bare wood needs compatible color and protection
If the scratch has removed the finish, a matching touch-up marker or stain may restore color before the area is protected according to the existing finish system. Avoid flooding sound edges with pigment.
Deep damage or widespread scratching may need professional work
Gouges that catch a fingernail, thin veneer layers, or widespread scratching are poor candidates for spot touch-up. Sanding without knowing available wear-layer thickness can cut through engineered wood or leave a depression.
