Long story short, my installer didn't rack my beautiful reclaimed wood floor. He had tons of light pieces grouped together. I asked him to remove the light pieces and patch in the darker pieces I had ordered as extra. They had already applied one layer of oil based poly when I asked him to do this. They broke out the board, cut the groove off and put in the new board. The repair looked great. They sanded the board (they did not tape it off) and it appears they overlapped the sanding on the other boards. They reapplied poly to the area. Then they buffed the entire floor and applied another coat of poly. It looked amazing. I woke up this morning and now I have this on every single area where they patched the board.
There are also tiny half moon circular spins under the poly, is that the buffer they used when it hadn't dried? Is it the sander?
How do I give them good direction and get this fixed?
