  • DECORATIVE BUILDING BOARD AND METHOD FOR PRODUCING SUCH A BUILDING BOARD
    Publication number: 20180339547
    Abstract: The invention relates to a method for the automated decoration of a building board, comprising at least one smoothing compound layer and preferably at least one colour coat. The method comprises the steps of smoothing and decorating the building board, wherein the smoothing includes the steps of (i) calibrating the building board to a nominal thickness, so that a surface of the building board has a height difference of at most 1 mm, (ii) applying a layer of a smoothing compound, (iii) pressing the smoothing compound into the surface structures of the building board, and (iv) recalibrating to the nominal thickness. Preferably, a plurality of smoothing compound layers are pressed into a calibrated surface of the building board and partially ground away again. The method is particularly well suited for the production of fire-resisting building boards.
