It is an object of the present invention to provide a decorating method capable of obtaining a masonry-like architectural plate.

[0005]

According to the present invention, there is provided a method for decorating a building plate, comprising: applying a coating of a first color to an entire surface of a substrate having a joint groove formed on the surface; The coating of the second color of another color is applied to the bottom of the joint groove.

[0006] In the architectural plate decorated by the method of the present invention, only the joint bottom is a different color (second color),
The edge portion also has the same color as the first color on the surface. Therefore, the edge of the building plate is visually recognized as if it is composed of tiles and side edges of stones that are integral with the surface, and the appearance of the architectural plate is excellent in real tiled or stone-like design. It will be.

In order to apply the second color coating only to the bottom of the joint groove, for example, the following methods (1) to (4) can be adopted. At the time of painting the bottom of the joint groove, a mask that exposes only the bottom of the joint groove is attached to the substrate and painting is performed. The bottom of the joint groove is painted using a stamp having a shape corresponding to the joint pattern; The bottom of the joint groove is painted using a nozzle that sprays paint only toward the bottom of the joint; the bottom of the joint groove is painted using a roller that rolls while hitting the bottom of the joint groove.

[0008] By any of these methods (1) and (2), the second color coating can be surely applied only to the bottom of the joint groove.

In the present invention, the depth of the joint groove is 5 to 20 mm.
In particular, by setting the thickness to 10 to 15 mm, it is possible to obtain an appearance rich in three-dimensional effect of deep ground tone.

In the present invention, it is preferable that the side surface of the joint groove is inclined in the forward direction, that is, inclined such that the groove width is narrower toward the joint bottom.

The base material having the groove side surface inclined in the forward direction is easy to manufacture. Further, it is easy to mount the mask on the side surface of the groove.

In the substrate used in the present invention, for example, as shown in FIG. 8, the height of the surface section defined by the joint groove may vary. Also, the depth of the joint groove may vary. As described above, the architectural plate having a variation in the height of the surface portion and the depth of the joint groove has a natural appearance without the quality of a standard industrial product.

In the present invention, after the entire surface of the substrate is coated with the first color, the surface may be partially decorated. In this way, for example, a mottled pattern with mixed light and shade, a dotted pattern with dark or light-colored spots scattered, and various other patterns can be provided. You can get a board.
