Hi ,mates.
We have a small area (130*320cm)in our kitchen that has wooden floor.We've noticed that bits of its colour seem to be flaking away .(picture 1)

And living room (about 25 square meters)is near kitchen ,there are some cracks in its wooden floor.
(Picture 2)

I'm concerned there could be permanent damage to the floor if I leave them.Can anyone offer some suggestions on how to fix these or make them look better? We are considering to sell this house next year.
Thanks
