I assume that your flooring was finished at the factory?

Yes, pre-finished with an aluminum oxide finish. They are Paramount floors.

Nature of the beast. No factory finished floor will have the flatness of an unfinished that is then finished on site.

that is why most pre finished have beveled edges. If its squared edge product you would get sections of 'overwood'. Some would be expected on prefinished but not neccessarily a 'defect'. No subfloor is ever perfectly level.

"No subfloor is ever perfectly level."

Or flat (the more important thing).

Thanks very much for the information -- I guess it's not an installation issue then.

I'm just somewhat disappointed that our floor seems "rougher" than others I've seen.

It might be a product quality issue. Perhaps you might want to bring your concerns to the dealer who sold you the goods and ask for an inspection of the floor.
