Light damage can easily be repaired in the original colour with the Quick-Step Repair Kit. Simply recreate the colour of your damaged planks with one of the seven wax pieces selected to cover all Quick-Step colours.
More serious damage can be repaired by replacing one or more planks, even in the middle of your floor. This is easy thanks to the Uniclic system.
Check out this table to know exactly which wax colours you need to mix to match your floor colour.
