The Flooring's Finish adds to Your Floor's Look, Feel and Maintenance.  The two main types are:

Satin PVC (Poly-Vinyl-Chloride)

Provides a more dull or unfinished look. PVC will require periodic polishing or buffing to retain its "like new" look. PVC is very resistant to staining.

High Gloss Urethane

Provides a more "wet" look. Urethane backing is low maintenance and scuff resistant.
