PURPOSE: To execute low-cost and efficient wall surface processing having excellent durability to peel by mounting a net fabric formed by braiding inorganic fibers in a fine mesh to a base material before formation of a wall surface, and mounting a pressure-sensitive type adhesive to the whole surface thereof.
CONSTITUTION: A base 3 is formed such that a number of ground boards 1 with a dimension of approximate 180cm×90cm×9mm of a plaster board are arranged and interconnected by means of a seams 2. A viscous net 4 is formed such that two glass long fibers are twisted together to form a mesh of approximate 2mm square, a net with a dimension of approximate 90cm×60m is formed, and the one surface thereof is coated with a coat consisting mainly of acrylic acid and synthetic rubber. The viscous net 4 is them mounted on the whole surface of the base 3. Thereafter, a plaster material is applied uniformly approximately 6mm thick by a trowel to form a plaster layer, and finally decorative fine grains are sprayed to form a surface finish layer 6. This method finishes a wall surface in the surface finish layer 6 durable to peel.
