|Hello all - this is my first post, and I'm a novice, when it comes to flooring installation, so please forgive my ignorance.|
I recently installed a 3/8" engineered wood floor -- over a concrete floor (elevated, not on grade) -- as a floating system, on a foam acoustical underlayment. It's a click-together system.
It sounds terrible to walk on - a mix of hollow thumps, and crackling rice crispies.
So, I'm pulling it up, and gluing to the slab with an acoustic adhesive (Sika T21).
My question (and I've done a lot of searching for an answer - but can't find a thing) -- is: Since I can't go back, after the flooring is glued down - can I also glue the tongues/groves of the boards to eliminate noises? I bought a bunch of Titebond tongue and groove glue, in case the answer is yes.
I know that expansion and contraction is the concern, but I'm thinking that the whole floor will expand and contract as a system, if I leave enough gap at the edges?
The rooms are small (10'x14') and the high-traffic areas that I'm most worried about (kitchen and hallway) have very short runs -- boards that are only 4' long (running perpindicular to the space).
Any advice is greatly appreciated.
