[0001]
BACKGROUND OF THE INVENTION
The present invention is a coating method in which a soil coating material mainly composed of natural soil is applied with a trowel to finish, and is excellent in adhesion to the base, has high hardness, strength and water resistance, and is a coated part after curing. The present invention relates to a method of applying a thin-film coating method, which has the characteristics and texture of natural soil, and can be applied both inside and outside buildings.
[0002]
[Prior art]
In recent years, living environments incorporating nature into urban functions have been oriented, and construction using natural materials as materials is also required for building floors and walls, ceilings, building outer walls, outdoor corridors, plaza floors, fences, etc. Natural, which has harmony and beauty with the natural environment obtained by the conventional plastering method, and can also contribute to health by utilizing the breathability, water absorption, water permeability, etc. of the material There is a need for a construction method using earth-coating material mainly composed of earth.
[0003]
However, in the conventional plastering method mainly composed of natural soil, the soil coating material itself is not strong enough to generate dust that is vulnerable to friction and scratches, and the difference in strength and shrinkage from the concrete underneath, or There is a disadvantage that the function and appearance are impaired in a short time due to the occurrence of peeling or collapse due to insufficient adhesive strength with the groundwork, etc., and when it is outdoors, it is re-mudded by rainwater or sprinkling, and the appearance and walking performance are impaired. Has the problem of collapse.
[0004]
In particular, the conventional plastering method has a lack of strength because it uses soil as the main material, and it has not been possible to construct it in the interiors of reinforced concrete buildings, such as the interiors of buildings such as schools, hospitals, and stores, and the floors of hallways.
[0005]
In addition, conventional coating methods that apply soil coating materials after the underlying concrete has completely cured, such as direct trowel press finishing and cement-based color cleat finishing, do not leave soil properties on the painted surface and are unique to the soil. It lacks the features of warmth and tenderness, and it takes time to dry and harden the base, and the construction period is prolonged, and the construction cost is expensive because of the construction man-hours such as the base treatment.
[0006]
Therefore, with the conventional plastering method, it is difficult to form a thin coating layer with a soil coating material mainly composed of natural soil on the ground surface of concrete, mortar, dirt walls, etc., and the ground surface has the same properties as the ground surface. It was not possible to make full use of the humidity control function and air purification function of the base itself by covering and integrating with the earth coating material.
[0007]
In addition, when painting with an organic coating material or a soil coating material containing an organic curing agent, the ground surface is sealed, although the strength and water resistance of the coating layer are excellent, and the above characteristics of the ground itself are utilized. I could not.
[0008]
[Problems to be solved by the invention]

[0010]
According to the soil thin coating method of the present invention, a thin coating layer having hardness and strength is applied to the ground surface at room temperature by applying the soil coating material directly to the ground surface with a trowel. The coating layer is made with a uniform thickness, eliminating the need for adhesive and assimilating agents, and maintains the properties and texture of natural soil in the paint layer. In addition, the surface has a dense and smooth finish, maintains the warmth and tenderness of the soil, and can impart design properties by a conventional plastering method.
[0011]

[0012]
Furthermore, according to the soil thin coating method, the coating layer can be finished with the same hardness and strength as pottery, and can be applied to the floor with a soil coating material, which was impossible in the past. . Moreover, by finishing the coating layer with high hardness thinly, peeling from the base and cracking can be prevented, and durability can be improved.
[0014]
In the soil thin coating method of the present invention, the soil coating material is applied before the base material is cured, particularly immediately before curing, so that the mutual penetration between the viscous base material and the soil coating material, the so-called “familiar” effect is obtained. Since the two are integrated and a paint layer can be formed with a strong thin adhesive layer between them, it is possible to prevent peeling of the paint layer from the base and a thin paint layer of about 1 mm. Formation is also possible.
[0016]
In the soil thin coating method of the present invention, raw mortar is applied to the base surface of an existing concrete floor, mortar wall or earth wall, boards, panels, etc. as a base, and the soil coating is applied before the raw mortar is cured. Since the material can be coated, the soil thin coating method can be applied to any existing base, and the same effect as described above can be provided.
[0018]
