We are in the middle of a first floor home renovation where we replaced some travertine tile with new oak floors. There were two previous rooms that already had wood floors that the install fingered in the wood for seamless transitions. This looks great.

The installer sanded down all floors and restained and put two coats of Bona Mega Water-Based Poly on top. We intended to do a buff and third coat of Bona Traffic once the project was complete, but we had some issues and wanted this forums opinion on if we should be concerned.

1. The floor was very rough (like sandpaper in some areas). The installer assured us that this corrected with the final coat of poly. I guess this makes sense, but just seemed odd. Thoughts?

2. In one area of our family room, there was what appeared to be bleedback (pictures can't quite show it, but that's what it looks like) on some boards and in between some boards. The installer felt it was related to pet urine or moisture, but I'm not sure this really possible (new floors 5 years ago, wife who keeps a very clean house, some of the areas covered by rug). Before he sanded this floor it did not have this issue. He came in and taped off the boards and tried to spot sand and restain the area but it sticks out like a sore thumb. He said if this doesn't fix it he'll have to replace the board. Is any of this right?

3. Around the boarder of our family room I can now see the nails that were put in the permeter boards. The installer assured me that he coudl fix this when he did the final coat, but it doesn't make sense to me as this just going to add another coat of clear poly. Does this make sense to you?

The installer is coming back next week to see if there can be anything else done to repair our family issues. I'm trying to get educated before he gives me a recommendation. We have a feeling that he's goin to try to sand only that one room and restain and fix, but given he wasn't able to match the area he spotted in, we're worried it won't be a seamless transition with the other wood floor areas (all connected)

Thank you in advance!
