Your floor is going to look really nice. How are you attaching it? Glue the edges and float it?
We aren't gluing. Nailing all the way to the end, and the installer is sanding end joints as he lays, even though it will be site finished after it's done. We debated gluing, biscuit jointing, etc., but this installer recommended floating without gluing even though he was willing to do so. We've seen his 4-5" width non end matched work, and it looks great. No severe curls. Obviously there will be some movement, but, since we're mixing 3, 4, 5 randomly, we are hoping for a real rustic/natural look. Gaps and slight lifts are acceptable to us.
