Q: I read a couple of threads that suggested water based polyurethane for floors may not be the best idea. Should we reconsider an oil based polyurethane before we start?
A: You can use water based finish for floors if so indicated on the label. The higher end finishes that flooring contractors use will not be purchased at Home Depot. For the home owner, an oil based finish if far easier to use, and will give you better protection, in my opinion. There are many good finishes on the market. I like the Circa 1850 Bowling Alley polyurethane.
