Abstract

The invention relates to a method for subsequently altering a decorative surface that is ready for use, including the following steps: providing a material panel with a decorative layer which is ready for use and has a first coloured. decoration and a protective layer with a structured surface. According to the invention, in order to provide a method for subsequently altering a decorative surface that is ready for use, with which the structures can be optically highlighted, without interfering with the mechanical or structural integrity of the decorative surface, a second coloured decoration is applied to the protective layer and unevenly distributed.

First claim

1 . A method for subsequently altering a decorative surface that is ready for use, comprising the following steps:
providing a material board with a decorative layer which is ready for use and comprises a first coloured decoration and a protective layer with a structured surface,
wherein
a second coloured decoration is applied to the protective layer and unevenly distributed.

2 . The method according to claim 1 , wherein the structured surface has elevations and cavities and the second coloured decoration is arranged in the region of the elevations and/or the cavities.

3 . The method according to claim 1 , wherein a larger quantity of the particles producing the second coloured decoration is arranged in the region of the elevations and/or in the region of the cavities compared to a central plane.

4 . The method according to claim 1 , wherein, for the second coloured decoration, colour particles in powder form are applied to the structured surface and surplus colour particles are then removed.

5 . The method according to claim 1 , wherein the colour particles are brushed off.

6 . The method according to claim 1 , wherein the colour particles are brushed off in one direction.

7 . The method according to claim 1 , wherein a fixing layer is arranged on the powdery colour particles.

8 . The method according to claim 1 , wherein a pigmented liquid surface coating is applied to the structured surface for the second coloured decoration.

9 . The method according to claim 1 , wherein the pigmented lacquer is applied by means of an applicator roller.

10 . The method according to claim 1 , wherein the structured surface comprises sections having high and low roughness and the second coloured decoration is unevenly distributed in such a way that a larger quantity of colour pigments is arranged at sections having higher roughness than at sections having, by way of contrast, lower roughness.

11 . The method according to claim 1 , wherein the structured surface has sections with different gloss levels, wherein the second coloured decoration is applied in a larger quantity at sections having a lower gloss level than at sections which have, by way of contrast, a higher gloss level.

12 . The method according to claim 1 , wherein particles made of graphite or carbon, ferromagnetic particles, iriodin or kaolin or mixtures of two or more of the aforementioned particles are used as powdery particles or as particles in a liquid surface coating.

13 . A material board comprising a panel which is ready for use, having
a decorative layer which has a first coloured decoration and a protective layer with a structured surface, an unevenly distributed, second coloured decoration is arranged on the protective layer.
