The kitchen walls are built on top of it, and it would be very difficult to replace the whole floor.
I am looking for an easy, decent solution and I have thought of the following one: 1. Sand it first, 2. Apply paste between the pieces that have space between them, 3. Paint black, to make it these fixes less visible.
I am not sure the black is a good choice, and if there are better alternatives. I have in mind a muddy black, not the shiny / sticky one you can get with varnish.
Does this make sense? Any suggestion on the material to use?
