Almost over ;)

I cut some more cardboard and instead of painting and polishing first, I glued them down to the floor.
As you may notice the tiles are much bigger than the ones I cut before - this way it will be easier to divide the room into the laboratory and office parts;) (Okay I found myself a good explanation not to cut small parts of cardboard anymore ;))
Here is the floor covered entirely with the cardboard and the tiles are painted and polished :)
I need to add fugue yet and flooring will be over - but the tiles need to dry a bit first.
