I'm in the process of having my wood floor resurfaced. I currently have oak and love the look after the sand. Very light in color!! We applied the sealer and immediatly the wood darkened to an amber color. I spot test with just the moisture cured Polyurethane and still it darkend the wood. How do I put a semi-gloss protectant on this floor and keep the light color? I was told to White wash the wood prior to the Polyurethane would keep the floor looking light like it was freshly sanded, Any thoughts?

We just had installed oak hardwood flooring in the house just bought. The whole thing was in a big rush because we had to move in in a short period of time. Now after the "dust" settled, when we look at the new floor we see that it is not perfectly installed. Some pieces of wood (don't know how is called) (they are in length of about 36 inch and wide 4.5 and one edge of it enters in the edge of the piece near it) are not fit exactly near the next ones. Some space of 1/8 of an inch makes our new floor not look very nice. There is any remedy for force the wood to fit properly? I imagine that if the culprit is in the middle of the room I have to move all of them to the end of the room. Any suggestions greatly appreciated. Thank you.
