Vinyl flooring brands will often make a big deal about how durable their products are. They will mention their fancy coatings, their lifetime warranties, their patent-pending constructions. But at the end of the day, once you understand how vinyl is constructed, it becomes clear there is only one spec that really matters: the wear-layer. Once the wear-layer wears through, the paper pattern will be damaged, and the floor will need replacement. So the thicker the wear-layer, the longer your floors will last and look great. If durability is a key criteria for you (and if you are opting for vinyl over laminate or wood, then it probably is), you could stop reading this article and already know 90% of what you need to know to make an informed purchase. A thicker wear-layer means a longer lasting floor.
