Gorilla Glue (an example of great success from picking a memorable name) is "just another" of the hard urethane glues, Elmer's calls it something bland like "furniture glue" and can't touch their sales. Same product AFAIK.
I'd also expect a hard urethane to be good in the floors, but if the rest of the flooring
is attached with a flexible material, and one spot gets repaired with an inflexible material...could cause something to pop later, since they wouldn't "move" the same way.
All the glues like Gorilla Glue foam up during the first hour after they are applied, take care to hang around with a damp rag to wipe off any overage. It dries rock hard.
