Thank you for your question and for your interest in our 5" x 3/4" Brazilian Teak Prefinished Solid wood floor. As is the case for all solid wood floors, you'll need to nail/staple down to a plywood subfloor. As such, gluing is not an option. If you're looking to glue down to your concrete slab, you'd want to go with an engineered product. Specific to Brazilian Teak, we do carry a [5" x 1/2" Brazilian Teak Prefinished Engineered[(https://www.houzz.com/products/brazilian-teak-prefinished-engineered-wood-flooring-sample-prvw-vr~70851154?lid=54308186) that would definitely be worth consideration. It is, by far, one of our most popular exotic engineered wood floors.

One thing to keep in mind with gluing down on slabs; you'll want to make sure that you use an adhesive with built-in moisture protection. We have several options that we'd be more than happy to provide you with if you were interested.
