Is it possible to install 3' carbonized bamboo flooring without gluing or nailing to the subfloor? I recently saw an episode on This Old House where oak planks were installed over a polyurethane vapor barrier simply by running a bead of wood glue down the tongue and putting it into the groove. No nails or glue was used to hold the floor down. They claimed that the floor would then expand and contract as a whole rather than as individual boards. I am interested in installing the bamboo flooring on a concrete slab subfloor that is 50 years old. The adhesive is very messy, hard to work with and costly! Any information would be appreciated.
