Laminate flooring is a multi-layer synthetic flooring product fused together with a lamination process. Laminate flooring simulates wood (or sometimes stone) with a photographic applique layer under a clear protective layer. The inner core layer is usually composed of melamine resin and fiber board materials.
It is important to keep laminate clean, as dust, dirt and sand particles may scratch the surface over time in high-traffic areas. It is also important to keep laminate relatively dry, since sitting water/moisture can cause the planks to swell, warp, etc., though some brands are equipped with water-resistant coatings. Water spills aren't a problem if they're wiped up quickly and not allowed to sit for a prolonged period of time.
