re: Glue or Float LVP floors

a shitty install of either method creates hard to fix issues. For example if you install floating floor in a bind, it will look great for a couple weeks then all start popping up or have giant voids under it, and the only way to fix that is to pull it all up and start over

On the other hand, a shitty glue down job can leave end joint gaps that you have to then go back and fill with a joint compound

so talk to the installer, look at his work, and go with whatever he suggests
