How Is Adhesive Used With Vinyl
When flooring contractors put down vinyl flooring, the material is held down to the subfloor via special adhesive. Manufacturers design the adhesive to hold the vinyl firmly in place and keep it attached to the subfloor in many different environments.
Flooring installers lay out the vinyl material, then fold back half of the floor. They spread a special glue specifically recommended by the manufacturer on the subfloor, then carefully lay the floor back down and use special tools to press it firmly. They repeat with the other side of the flooring until the whole thing is in place. As the sticky substance sets, the vinyl flooring becomes extremely durable and resistant to wear and tear.
Adhesive Problems
Vinyl flooring only performs as well as the adhesive securing it, so problems with the adhesive can compromise the integrity and resiliency of the flooring. This special glue can lose its grip due to excessive moisture, improper curing, improper installation, and contamination before application. If any of these conditions are present when the vinyl is being laid, it can fail and therefore cause the vinyl flooring to have problems.

This is good advice. Yet after laying all the vinyl floor planks, I noticed the ends came up. Sure wish someone could offer some help.
Can I use liquid nail Glue to keep the ends down?
I suggest that you get an inspector to diagnose the root cause issue before moving forward with a remedy.
