1. A coated panel selected from floor panel, wall panel and furniture panel and comprising one or more layers of a coating material applied to the surface of a panel construct, the coating material defining the surface of the coated panel, wherein said coating material is a solution polymer or dispersion of an elastomeric resin-based material in water or another solvent, wherein the water or other solvent present in the coating material is substantially removed by a drying process such that a layer of the elastomeric resin-based material remains on the surface of the panel construct, and wherein said layer of coating material has been bonded to the surface of said panel construct by use of a pressing and heating operation, subsequent to the drying process, such that the layer of the elastomeric resin-based material are cured and crosslinked, and bond said coating material to a surface of said panel construct, and wherein said coating material is based on thermoplastic resin comprising polyurethane and/or Acrylic resins,
wherein the layer of the elastomeric resin-based material has a weight between 3 to 150 grams per square meter.
