Glued Down Engineered Flooring
Got a question about this stuff. I’m gluing down an engineered floor of 5″ wide, 1/2″ thick planks over a concrete floor. Using moisture curing urethane adhesive (At $200 plus per bucket, it’s too expensive to call it Glue!). The instructions say to leave a 1/2 inch gap at each wall for expansion. This doesn’t make sense. If that floor were to expand that much, it would have to totally shear off the glue holding down the planks along the wall, and that doesn’t seem possible. What gives here? Is that a realistic situation?

I agree that sounds a little bogus. Why not call the manufacturer and ask them why?
yur glue is elastic enough to do that..
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
Maybe they say 1/2" since the guy writing the instructions doesn't know if you are doing a 7'x7' room or a 70'x70' room. We use that stuff in the houses I build. Floor guys leave about a 1/4" gap.
i installed engeneered flooring with glue this summer. it has now shrunk, width and length. followed instructions to the letter. any ideas why?
