Method for finishing a large-size supplied building panel

A method for finishing a supplied building panel with an upper side and a lower side, the method comprises:

• a) in a first embossing step, embossing a relief at least into the upper side in a form of at least one strip-shaped depression comprising a bottom wall with a depth (T),
• b) applying a decorative paper to the upper side;
• c) applying an overlay paper to the decorative paper an abrasion-resistant layer;
• d) feeding the thus-prepared structure to a press and pressing the structure;
• e) during the pressing, at least one strip-shaped depression is again embossed in a second embossing step without changing the depth (T),
• f) the upper side includes a press skin that has a thickness of 0.3 to 0.5 mm;
• g) a bulk density of the building panel the top layer that forms the upper side is between 950 and 1.000 kg/m3,
• h) the lower side includes a backing layer prior to pressing;
• and further comprising:
• i) heating the building panel using steam prior to the embossing until it reaches a surface temperature of 30 to 50° C.,
• j) applying an aqueous melamine resin to the upper side as a tempering agent before or immediately after the embossing;
• and
• k) the press is a short-cycle press with pressure and temperature.
