Several months ago (September) I installed some 2 1/4 in oak flooring in a new addition, then sanded and finished it. Thought I'd mention how impressed I am with the polyurethane I used this time. I've done floors before and always used a water-based satin poly like Minwax. In fact the rest of my house was done with that stuff about 3 years ago. But for the new addition, my wife wanted a matte finish. I was like, are you serious? She said yep. Happy wife happy life... So this time I used Bona Naturale. After getting over the sticker shock, watched a few videos on the "approved" way to apply it, then went for it. 1 Gallon sealer and 3 gallons of finish later (covered 330 sq ft with 4 coats) and I have to admit she was right. Never would have thought I would like a matte finished oak (no stain). By the way, Bona sells their "approved" roller and pad applicator for their stuff. Save your money. Any brand will work as long as it is quality. For a roller, I used 3/8 nap. I wanted lambswool and the Big Box Store was out, so I just got what I could. Worked great anyway. I almost posted this last September, but I wanted to wait and see how the floor held up. Dog, muddy kids feet, dragging furniture, etc and 5 months in still looks perfect. Matte hides all the little tiny scratches. Here's a pic after it was done but before all the baseboard moulding put back and touch up paint.
