My newly built condo has beech wood flooring that has been stained dark a la walnut. In the same building the penthouse units have a patchy light and dark finish that I like better. I was told that it was the same wood flooring that was finished differently. I want to refinish my floor to look like the penthouse units. The patchy finish looks like a fancy floor with different kinds of wood used. The builder's wood floor guy quoted me a price of $6/SF to refinish it. I think it's too high. Can anyone tell me the name of this type of wood finishing? Is it a specialty or can anyone do it? Also, I am thinking of asking for 2 extra coats of polyurethane to make it last, is there a down side to extra poly?
TIA
