Abstract:
The disclosure relates to a method for finishing a panel, the method includes a) a relief embossed into the upper side in the form of at least one strip-shaped depression with a depth (T), b) a decorative paper applied to the upper side, c) an overlay paper applied to the decorative paper as an abrasion-resistant layer, d) the lower side provided with a backing layer, e) the structure pressed at a high pressure and temperature, and f) during the pressing, at least one strip-shaped depression again embossed in a second embossing without changing the depth (T). Also, the upper side features a press skin that has a thickness of 0.3 to 0.5 mm, the bulk density of the panel in a top layer is between 950 and 1,000 kg/m3, and an aqueous melamine resin is applied to the upper side as a tempering agent before or after embossing.
