If you get a damaged surface on an oiled wooden floor, we recommend that you maintain your floor. The oil refreshes the surface and hides minor scratches.
If you get a damaged surface on a lacquered wooden floor, you can use a touch-up pen to fill in and hide the damage.
Should you get such a large damage that the floor cannot be saved, it is also possible to replace individual planks. Replacing a floorboard takes about an hour and on Bjelin's Youtube there is also a film that describes changing the damaged area.
