Laminate floors are virtually scratch resistant, however, heavy sharp objects such as furniture feet with nails sticking out may still leave scratches. There are certain remedies one can do to get rid of scratches to laminate floors, as well as some tools and solutions to use.
Examine the extent or size of the scratch.
For light scratches you can use a scratch repair pen or wax crayon. Using them on light scratches can hide or camouflage the scratches and would render them invisible from afar unless examined closely. Choose the shade that is similar to the laminate colour you have.
For heavy or deep scratches, you can use a wood filler and colour fill such as ColorFill manufactured by Unika.
Use a spatula or putty knife to apply the wood filler. Sand the wood filler so that it becomes level with the rest of the laminate surface.
Apply colour ink to light scratches or deep scratches that have been filled with wood filler.
Allow to dry. Retouch as needed.
Make sure not to move furniture without using a rug or felt underneath to protect your laminate floor.
Do not sand laminate floors for it will not work or will just add damage. If the scratch is so huge and it is very unsightly that even with the solutions given above they would look unattractive, try replacing the plank. This would mean removing all the planks close to the corner or wall until you get to the one that is affected. Laminate wood is easy to install since you do not need glue or nails. After replacing the scratched plank, replace the planks to their original position.
