I see construction cuts (also called control cuts and expansion cuts) in your beautiful coated floors.

For people that haven't had it done yet, consider putting concrete (hardening type) in the cuts before the floor is covered.
You will not be sweeping dirt and having stuff stuck in the cuts.
(it will not have any affect on the floors ability to move slightly, expand, etc.)

I've even dropped washers into them. Nooooooooooo.
