OK, there are couple of unfinished, engineered products out there. Owens Plank and Bruce Studio B are those I am aware of, but I'd like to hear of others too.

Anyhow, in this ongoing process of figuring out what to do, one emerging option is to float as high a quality of floor as possible. I don't like that too much and I don't like prefinished. But glue down and nail down both have issues of their own in my situation.

So the question is: Can an unfinsihed, engineered floor be floated and then sanded? If so, how?

I searched and read some threads -- sounds like drum sander should be avoided due to risk of chatter. I am reasonably adept with drum, have used pad sanders with some sucess as well. Have never used a belt floor sander and I don't know of one can be rented in my part of the world.

Thanks again......

Just use a trio. Hell, you could do the whole thing with a square buffer too. I'm sure it would take a while, but then you won't have to take much wood off either.

I'm missing your whole point on doing this.

A good quality, engineered prefinished sq. 4-sided product that is designed to float would not be any drawback from a site-finished.

I believe the factory finish is better, no mess, no sanding, and just as smooth as a site finished if you are floating it.

Check out the Award on this site. I'm installing the Roman Summmer, a 6" wide, beveled edge engineered. I used the staple down method, as well as floating in a section over a concrete slab that made up the sunken living room. Floating it worked well. Fit was very good, and the finish is proven tough. I have to say, that the Walnut is one of the prettier woods I've seen, as well.

The Owens plank can be floated, but your subfloor better be flat!
