Pros

Glue-down vinyl tile and plank flooring is a popular option if you are looking for a more secure or commercial grade installation. Glue-down flooring is usually required for commercial or public spaces because of the physical movement. Due to this constant traffic, without gluing it down, the floors could shift or have enough movement to cause buckling, cracking or creaking. If you are experiencing any noise or have noticed the floors move, then it could be time to find a flooring installer to help fix the problem. One solution would be to drill into the floor and force glue under the material. Another tactic would be to actually remove the floor and re-apply with some kind of manufacturer recommended adhesive. Usually a spray or light paste.

Cons

Glue-down might not be a good option if you are someone who likes to update your floors every 10 years. Glue-down installation is recommended to preformed by a professional installer. The use of a trowel to spread on glue is the most common method of preparing the floor for installation. There is also spray lock can adhesives but those are not as likely to hold if placed a high foot traffic area.
