Additional InformationExpressive Flooring The most common designs have a wood grain appearance; some are made to look like stone or marble. Laminates are designed to look good for many years with a minimum amount of maintenance. Laminate flooring consists of four main components that are bonded together. A wear-resistant decorative surface made of resin-based melamine/aluminum oxide is bonded to a moisture resistant wood composition-based core. A balancing backing is bonded to the underside of the core. On the top is a clear cap sheet of aluminum oxide, which provides the protection and stain resistance. Since the resin-filled wear layer is so dense, it becomes extremely difficult to stain, scratch or burn. Ease of installation is one factor that contributes to the popularity of laminate flooring. It uses a tongue and groove interlocking system, which can be installed over the top of an existing substrate. Plywood, concrete slab, sheet vinyl flooring, hardwood flooring or virtually any other basically flat hard surface is a suitable base for laminate.
