Hello,

I have a client that wants to install engineered hardwood bamboo flooring on his newly built Florida house. The house has a nice power trowel finished concrete slab and the bathroom have ceramic tile installed at 1 1/16" thick. The owner wants a level installation of the bamboo. I was thinking to install 3/8" plywoood underlayment below the 5/8" bamboo.

- Would this be the correct way to go?

- What kind of plywood?

- Gaps? Vapor Barrier? / Glued / Fastened?

Thanks much.
