Liquid Nails is a brand name of one of the polyurethane construction adhesives available.

JB Weld is a product made with epoxy, modified with fillers. Not the same as a pure epoxy.

As a1Jim and ArtistryinWood said, polyurethane construction adhesive is what you need.
There are many different formulations of all types of glues.
You need to read labels of the ones available to you.
Some will be more water proof, some will handle foot traffic better, some will handle expansion better.
You just have to read the labels, or talk to people who use it and go by their recommendations.

ditto on the polyurethane construction adhesive. Read all labels and use accordingly.
