I'm finally getting around to installing an engineered floating floor in our living room. It's 1/2" thick. I am looking at using 1/4" cork underlayment underneath such as this from Home Depot.
It mentions 'cork underlayment adhesive'. Is this necessary? I figure since it's a floating floor to begin with, there's no real reason the underlayment can't be floating as well, is there?
The cost of the adhesive isn't a big deal, but I figure if I can save the mess/time, I will (not only for me, but any future person wanting to replace the floor). Are their strong reasons to adhere the underlayment?
Thanks for the answers thus far! So, a follow-up question: If it's best to adhere the underlayment, what would be a pragmatic solution other than the mess of floor adhesive? The suggestions thus far:
- tape the seams of the underlayment together (duct tape? would other tape be better?)
- Staple the cork to the subfloor (will that cause issues with the underlayment expanding/contracting?
