Glue-down vs floating LVP: which install method to choose
Once the material is chosen, the next question is how it attaches — or doesn't. Both methods are legitimate; they just suit different situations.

Floating floors
A floating floor clicks together into a single sheet that rests on underlayment, held in place by its own weight and the perimeter trim. Nothing bonds to the slab.
It installs faster, tolerates a bit more slab variation, and individual sections can be lifted for repairs. It also needs expansion gaps at every wall and fixed object, and in very large open runs it can sound slightly hollow.
Glue-down floors
A glue-down floor is bonded to the slab with full-spread adhesive. It feels solid underfoot, transmits less sound, adds minimal height and does not need the same expansion strategy across large spans.
The trade-off is prep. The slab has to be clean, flat and within moisture tolerance before adhesive goes down, and a future repair means cutting out and re-bonding a section.
How buildings influence the choice
Many Miami-Dade and Broward condo associations specify an acoustic rating for the finished assembly. Some approve floating systems with a rated underlayment; others prefer glue-down. Getting the association's requirements before ordering material prevents an expensive reversal.
- Large open living areas: glue-down usually feels and sounds better
- Height-restricted thresholds and elevators: glue-down adds less height
- Slabs with minor variation and quick timelines: floating is often practical
- Buildings with sound ratings: follow the association spec, whichever it names
