Description of the Related Art Conventionally, inorganic materials have been widely used since ancient times because of their simpleness, solid feeling and high durability. There is "plaster" as one of such inorganic materials, but plaster is mainly used as a raw material of slaked lime, funori, kakumata, bamboo grass, etc., and is mixed with water with great effort to use. It is used as the exterior and interior materials of Japanese buildings such as temples and temples.

きた。The above-mentioned plaster composition was used as an undercoat material by mixing slaked lime with susa, a thickener, water and the like, and further mixing sand to form a sand plaster, which was used for preparing a groundwork and preparing a groundwork. . In addition, as a top coat material, slaked lime, Susa, thickener,
It has been used by mixing water or the like and, if necessary, a colorant such as a pigment. Recently, a mixture of slaked lime with a thickener added and only a powder is sold, but it is difficult to add water to the above mixture at the construction site to knead it into a workable state. It took a lot of effort. That is, there is a problem that dust is generated and the mother's daughter is easily formed because of high viscosity. Therefore, a composition obtained by adding water and kneading is put in a plastic bag or the like for sale. Furthermore, various studies as described below have been conducted for the purpose of improving the water resistance, waterproofness, and durability of plaster, or for the purpose of improving the finish appearance.

な塗材を得る製造方法が記載されている。In Japanese Patent Laid-Open No. 54-13537, grain powder is mixed in the main raw material of plaster to improve water resistance, waterproofness, stickiness, solidity, toughness, corrosion resistance and heat resistance. An improved stucco composition is described. JP-A-54-43930 describes a plaster composition in which vegetable oil is mixed into plaster to impart water resistance, waterproofness, and corrosion resistance. JP-A-54-105132 describes a plaster composition having improved corrosion resistance by mixing alcohol into a plaster raw material. In JP-A-54-85226, slaked lime, bleached wood pulp crushed product, and a plaster composition containing a water-soluble cellulose derivative as a main component are spray-coated, and air is blown while the composition maintains fluidity. A coating method for applying a surface pattern is described. Japanese Patent Application Laid-Open No. 55-90451 discloses a coating which contains slaked lime, a fibrous additive, and a cellulose derivative as a water-soluble thickener as main components, and a surface pattern is formed by using a finishing roller having a pattern groove. The law is described. JP-A-60-16855 describes a plaster composition in which a synthetic rubber emulsion is contained in a kneaded product composed of slaked lime, aggregate, inorganic fiber, synthetic sizing agent, and water to prevent the occurrence of cracks. Has been done. Japanese Patent Laid-Open No. 61-195171 discloses an undercoat mud prepared by selecting from a specific raw material group such as rough wall soil and intermediate coating soil, an intermediate coating mud or a plaster coating material, kneaded and kneaded.

今日、“漆喰仕上げ”は減少の一途をたどっていた。However, although any of the above compositions is applied by trowel coating, this finishing coating requires the skill of a plasterer. That is, it was difficult to make the white wall even and uniform, and it was even more difficult to finish the colored plaster evenly. Moreover, with the aging of plasterers and the decline of young technicians becoming a serious problem, "stucco finishing" was steadily decreasing.

されていた。[0006] In addition, plaster absorbs carbon dioxide in the air and hardens over a long period of time after construction to improve durability, but cracks easily occur in the process, so that wall surface remains even after construction. As a result, there was a demand for a finishing material that is aesthetically pleasing and highly durable.

Further, a simple and tasteful wall surface is required, and a breathing function, a moisture permeability function, durability, etc. are also required, and a new finishing material has been desired. Incidentally, finishing materials based on organic materials such as paints have already been developed and have been widely used because they are easy to apply, but they have not been able to express the solid feeling, high-class feeling and durability of inorganic materials. Therefore, the workability of the organic material is good, the finish is uniform, and various textures can be expressed. In addition, the inorganic material has the high-class feeling, the solid feeling, and the durability, and the inorganic material enables a variety of finishes. A finishing material composition and a construction method have been desired.

形成（造形）、こて押さえなどを容易にする。Silica fume, alcohol, and ethylene glycol are for eliminating uneven drying as much as possible and making the color tone after finishing uniform. That is, the conventional stucco composition not containing the above-mentioned components had a high viscosity and a high water retention property, so that the drying was very slow, color unevenness was likely to occur, and the strength was also delayed. The silica fume prevents the Ca ions dissolved in the undercoating material composition from being liberated and deposited on the finished surface of the undercoating material composition, and thus can prevent color unevenness. Further, it improves the fluidity of the kneaded product and improves the workability. Also,
Generally, a highly volatile alcohol evaporates by embracing water present in the undercoat material composition, and thus exhibits the same drying property as that of the resin-based finishing material and accelerates the development of strength. In addition, ethylene glycol, which is generally low in volatility, prevents drying of only the surface of the undercoating material composition and makes it possible to uniformly dry the entire surface including the inside of the composition. ), Make it easier to press the iron.

ば良い。The water-soluble thickener prevents dripping after forming (modeling) a convex portion as in the case of the bentonite. Also,
It imparts viscous behavior, thickening effect, miscibility during kneading, stability of viscosity, and water retention. The water-soluble thickener can be appropriately selected and used from commonly used ones such as methylcellulose and hydroxypropylmethylcellulose, and the addition amount may be determined in consideration of water retention and workability.

験して適宜に選択すれば良い。Dispersants such as polycarboxylic acid type and naphthalene sulfonic acid type dispersants improve the drying property by dispersing and mixing the undercoating material composition with as little water as possible, and further reduce the amount of Ca ions dissolved in water. To prevent color unevenness. When a colorant is added, the colorant is stably dispersed to prevent color separation and color unevenness. Further, when the kneaded product of the undercoat material composition is filled in an appropriate packaging material, the viscosity of the kneaded material is changed to prevent the composition from becoming clogged and the fluidity is prevented from being lost. Allows use in the state. This dispersant may be appropriately selected by testing in advance a colorant that does not cause color separation or change in viscosity of the kneaded product.

必要である。When an organic resin-based composition is used as the overcoating material composition which is applied to the surface of the undercoating material composition after being dried, the undercoating material composition cannot absorb carbon dioxide gas. In addition, curing is insufficient and sufficient physical properties cannot be obtained. Further, since the drying after the construction is fast, for example, the topcoat material composition applied to the entire surface of the undercoat material composition having the convex portions formed thereon is dried even if it is attempted to wipe off the topcoat material composition adhered to the convex portions. Cannot be wiped off.
Therefore, it must have breathability, breathability, and appropriate drying properties, and must have a composition similar to that of the undercoat material composition. Further, a dark color is also required for the design, and therefore a composition that does not cause color unevenness due to whitening is required.

Further, ethylene glycol is added so as not to dry until the upper coating material adhering to the convex portions of the lower coating material is wiped off, and is preferably added in the range of 1 to 10%. Furthermore, calcium carbonate improves the action of the white pigment, the strength adjustment of plaster, and the trowel slip during trowel application. Further, to the top coat material composition of the present invention, in order to improve the adhesiveness and the water resistance, a synthetic resin emulsion such as an acrylic type or vinyl acetate type may be mixed within a range that does not hinder the wiping operation.

工法を提案するものである。The undercoating material composition and the topcoating material composition can be used individually for finishing, and they have very good workability. However, since it is a single color finish, it is not visually interesting especially when finishing a smooth surface. Therefore, the present invention also proposes a construction method in which various textures can be expressed by using the undercoating material composition and the overcoating material composition having the above-mentioned constitutions, and moreover, various finishes can be achieved by the color of each composition. That is, the present invention is
The undercoating material composition having the above-mentioned constitution is applied using a trowel or a jig, a roller or the like so that a convex portion is formed (modeled), and after drying, the above-mentioned undercoating material composition having the same color or different color The present invention proposes a method of coating the above-mentioned topcoat material composition on the portion excluding the above-mentioned convex portions.

る。The above-mentioned convex portions form a desired surface pattern (convex portion) by an appropriate method while being coated with the undercoat material composition and have fluidity, and apparently water floating and the like disappear. The surface treatment of the convex portion may be performed in a dry state, and the method is not particularly limited, but the following methods are available, for example. After the undercoat material composition is applied to the wall surface with a trowel, a wooden jig is pressed against the wall surface at a right angle to pull it up, and after the water is drawn, the trowel is moved up and down and pressed to form an iris-shaped pattern. Also, press the wooden jig at a right angle against the wall and pull it up while turning it, and after drawing water, press the iron while turning it,
A rose pattern is formed. Furthermore, patterning is performed with a mastic roller, and after water drawing, it is pressed with a trowel to form a gussetless pattern, and when patterning is randomly performed using the butt of a metal iron, a hydrangea pattern is formed.
