Abstract

PURPOSE:To leave the colors of an aggregate as it is, to optionally select the color of a wall surface and to remarkably vary the colors of the aggregate and backing wall surface by using this simple coating method. CONSTITUTION:The surface of the wall is firstly colored, the aggregates of the desired colors and shapes are mixed into a transparent or translucent coating soln. to obtain a coating, and the coating is sprayed by a gun, etc. When a tile is sprayed with the coating, the bundles and rugged parts as the congregation part of the aggregate are scatteringly formed on the backing colored surface to make the backing coloration apparently visible, and a coated surface of extremely various coloration combined with the coloring effect of the aggregate at the bundle is obtained. In the case of lithin spraying, the aggregates are regularly spaced to make the backing colored surface visible. Furthermore, a coating consisting of a coating soln. having elasticity and an elastic aggregate such as acrylic rubber is sprayed after drying to conceal the cracks of the wall surface from the coated surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a coating construction method,
Particularly, the present invention relates to a coating construction method for forming an aesthetically pleasing coated surface on an outer wall surface or an inner wall surface of a building or the like.

[0002]

2. Description of the Related Art A coating technique for forming a coating surface with a desired pattern and color on a wall surface of a building or a house
The walls of the building are protected from deterioration due to the environment such as rain, snow, and air, and the atmosphere is protected, and the appearance and aesthetics are presented by appropriately selecting the color and pattern of the coating material. Conventionally, such coating is not only with a normal paint coating solution, but is also called so-called ricin, spray tile, stucco, which is sprayed with a synthetic resin paint containing colored sand, porcelain sand, etc. As for the coating form, since it is possible to form an uneven surface on the coated surface and obtain a wider variety of aesthetics, it has been widely adopted.

[0003]

As described above, the conventional coating technique using a coating liquid in which an aggregate such as lysine or skin is mixed is an opaque aggregate such as colored sand or ceramic sand as the aggregate. Is used to hide the groundwork. Therefore, when the coating liquid is sprayed on the wall surface, the finish color of the wall surface is uniformly determined by the color of the aggregate and the color of the coating liquid, and the underlying color cannot be visually recognized. Also, in sprayed tiles and stucco, the aggregate is usually not glossy and the color is not clear, and the top coating liquid is also colored and opaque, so the color of the aggregate itself is hidden by the coating liquid and the finished coating. There is a problem that it is impossible to obtain the beauty of the surface and various colors.

Therefore, an object of the present invention is to provide a simple coating construction method in which the color of the aggregate can be used as it is, the color of the wall surface can be arbitrarily selected, and the variety of colors of the aggregate and the base wall surface can be remarkably expanded. To provide.

In order to solve the above-mentioned problems, a coating method according to the present invention comprises a pretreatment step of performing a pretreatment such as cleaning of a surface to be coated, application of a surface treatment agent, and coloration of the surface, On the pretreated surface to be coated, a paint obtained by mixing transparent or semi-transparent adhesive coating liquid with a piece of aggregate having a predetermined color and shape is used. It comprises a spraying step of spraying so as to be discretely spray-formed, and a drying step of drying the coated surface by the spraying step.

[0006]

In the present invention, after the surface of the wall surface is ground, the paint obtained by mixing the transparent or semi-transparent coating liquid with the aggregate of the desired color and shape is sprayed with a spray gun or the like, and the uneven portion is grounded. By forming discretely on the colored surface,
The underlying coloring is visually recognizable as it is, and in combination with the unevenness of the aggregate or the color effect of the aggregate, it is possible to obtain an extremely wide variety of painted surfaces. Further, after drying, spraying a coating liquid having elastic properties and a paint made of elastic aggregate such as acrylic rubber or hard acrylic aggregate can prevent cracks on the wall surface from appearing on the coated surface.

EXAMPLES Next, examples of the coating method according to the present invention will be described. As a coating liquid in one embodiment of the present invention, a transparent or translucent coating liquid is used, and an aggregate composed of fragments of plastic or glass molded into a transparent polyhedron which is colored or colorless in the coating liquid is stirred. To mix. As the aggregate, it is possible to use a crushed piece of acrylic resin that emits light when irradiated with specific light, or a crushed piece of synthetic resin, ceramics, porcelain, concrete, or the like. As for the size of aggregate,
A diameter of about 0.1 to 3 mm is preferable in terms of gloss and aesthetics of the finished coated surface, but the size can be arbitrarily determined depending on the type of the building on the wall surface to be coated. As the coating liquid, a transparent clear coating material such as an acrylic copolymer resin or other semi-transparent coating liquid can be used. At this time, a coating liquid having adhesiveness is used in order to firmly fix the aggregate to the base coating surface.

The aggregate is preferably contained in the coating liquid in a volume ratio of 2 to 4 times in order to improve work efficiency. For workability, the clay of the paint mixed with aggregate is 100-250 at 25 ° C.
0 cP is preferred.

When applying the above-mentioned paint to a wall surface, first, as a pretreatment, the wall surface is washed with chemicals, water, etc., dried, and then an undercoating material is applied to the wall surface to be coated in a desired color and pattern. Color with the color (background coloring). After that, the above paint is sprayed onto the underlying colored surface using a spray gun and dried. This spraying can be performed by ball spraying (spray tile pattern) and lysine spraying. Since the coating material in this example uses a transparent or semi-transparent coating liquid, by the above-mentioned ball spraying, the ball portion, which is a lump portion of the aggregate, becomes transparent or semi-transparent, and the outer surface becomes the base. The colored surface can be visually recognized as it is, and the coloring of the underlying color can be remarkably embodied without being hidden as in the conventional opaque colored coating liquid. Further, in the lysine spraying, if the aggregates are evenly distributed with a space provided between them, the underlying coloring can be realized. In this embodiment, it is particularly effective when the base color is a light color. At this time, if the shape, color, pattern, etc. of the aggregate constituting the uneven portion are arbitrarily selected by comparing them with the color of the above-mentioned base coloring, the contrast between the base color of the wall surface and the color of the aggregate, a synergistic color effect Gives an extremely wide variety of aesthetics. Further, if the material and shape of the aggregate are set to have diffuse reflection characteristics, a more delicate color sense can be obtained.

In addition to the above embodiments, a material having elasticity after drying is used as the coating liquid, and an elastic material such as acrylic rubber is used as the aggregate, or a hard aggregate is also used. An elastic coated surface can be obtained, and even if a crack is generated on the wall surface due to an earthquake, ground subsidence, aging, etc., the coated surface can be prevented from cracking.

[0011]

As described above, the coating method according to the present invention can be obtained by preliminarily coloring the wall surface and then mixing the aggregate of a desired color and shape in the transparent or translucent coating liquid. Since the paint is sprayed with a spray gun or the like to form the irregularities discretely on the underlying colored surface, the irregularities are covered with a transparent coating liquid, and the underlying coloring can be visually recognized as it is, Combined with the color effect of the aggregate of the uneven portion, a coated surface with a wide variety of colors can be obtained. In addition, it is possible to prevent cracks on the wall surface from appearing on the painted surface by spraying a paint composed of an elastic aggregate such as acrylic rubber or a hard aggregate after drying, which prevents the appearance of cracks on the painted surface. It is possible to paint excellent in environment and atmosphere such as water resistance and alkali resistance. Further, according to the present invention, the coating is completed only by spraying after the base is colored, which is extremely advantageous in cost as compared with the conventional coating method for obtaining the same effect.
