Wood floor on wall installation
I'd like to install 5/8" wood floor on a 11' high wall. Basically the wall is comprised on standard sheetrock on metal joists. I was hoping to save space in the apartment and glue the wood flooring to the sheetrock, but my contractor is recommending 3/4" plywood underneath, and then nailing the wood floor to the plywood on the wall. This will obviously take up a lot more space in the apartment, and I am wondering if it is necessary.
How about using 1/4" plywood and gluing the flooring to that? Or simply glueing the flooring to the sheetrock? The best method is one that conserves space but also ensures that the wood wall is sturdy.
