Abstract:
1. A method for producing a wall board for mounting on a wall structure, wherein the wall board is produced based on a body element which essentially has the shape of a rectangular parallelepiped including two opposing main sides having relatively large delimitation surfaces and four edge sides having relatively small delimitation surfaces, the method comprising: mechanical surface processing of a first edge side of said edge sides of the body element, which comprises removal from the first edge side a surrounding layer covering the first edge side, and wherein said mechanical surface processing attains a flat surface structure on the first edge side that extends from a first to a second of said two main sides; applying a first surface treatment layer on the first edge side; arranging a first edge strip along the first edge side, the first edge strip comprising: mechanical surface processing of one second edge side of said edge sides of the body element, which second edge side is parallel with the first edge side, wherein the second edge side attains a flat surface structure extending from the first main side to the second edge side; applying a second surface treatment layer on the second edge side; arranging a second edge strip along the second edge side, the second edge strip comprising a second distal edge surface and a second proximal edge side opposite thereto which is flat, and a second primary surface between the second proximal edge surface and the second distal edge surface, and the second edge strip being arranged with the second proximal edge surface against the second edge side such that the second primary surface and the body element's first main side form an extension of the first, flat and essentially unbroken surface; and applying the first reinforcement layer on the extended first, flat and essentially unbroken surface such that the first reinforcement layer covers the first main side, the first primary surface and the second primary surface.
