Abstract
Description
[Technical Field]
[0001] The present invention relates to a coating method, and more particularly to a method for coating interior and exterior floors and walls of buildings and exterior floors and walls with a marble-like finish, i.e., a marble-like pattern. [Background technology]
[0002] Marble is used as a material for buildings and exteriors, or as a material to be attached to floors, walls, etc., in order to improve aesthetics and impart a sense of luxury, etc. However, marble is expensive and is therefore avoided for use, and there are also problems with marble being difficult to use on walls, etc., due to its weight.
[0003] Therefore, in the past, efforts have been made to improve aesthetic appeal by painting a marble-like pattern rather than using actual marble. Patent Documents 1 to 3 disclose techniques for forming a marble-like pattern by painting a frame to which stretched silk floss is fixed, by bringing the frame close to the surface to be painted and spraying paint onto it.
[0004] The techniques disclosed in Patent Documents 1 to 3 involve painting using stretched silk floss as a so-called masking material. That is, the techniques disclosed in Patent Documents 1 to 3 involve spraying paint onto areas where there is no silk floss, leaving only the areas where there is silk floss unpainted, forming a marble-like pattern.
[0005] Therefore, the techniques disclosed in Patent Documents 1 to 3 have the disadvantage that a large amount of paint is required to paint a wide area around the marble-like irregular streaks, and there are problems such as the inability to easily and inexpensively give a marble-like appearance to the floors and walls of existing buildings and exterior structures.
[0006] Furthermore, the spray painting methods of the above-mentioned prior art have the disadvantage that only one color can be used for the paint color around the streak pattern. Furthermore, these painting methods have the disadvantage that the spray painting is performed at a certain distance from the painting surface, making it difficult to finely adjust the color during painting. Furthermore, since the streak pattern is not painted, the streak pattern is realized only in the color of the original base. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Japanese Patent Application Publication No. 57-038966 [Patent Document 2] Japanese Patent Application Publication No. 4-277056 [Patent Document 3] Japanese Patent Application Publication No. 9-245510 Summary of the Invention [Problem to be solved by the invention]
[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method for easily and inexpensively painting a marble-like pattern with a good finish on the floors and walls inside and outside buildings and the floors and walls of exterior structures. [Means for solving the problem]
[0009] The coating method of the first aspect of the present invention is characterized by comprising the steps of stretching silk floss, fixing the stretched silk floss to a frame, applying paint to the backside of the silk floss fixed to the frame, bringing the front side of the painted silk floss into contact with a surface to be coated, and pressing the backside of the silk floss in contact with the surface to be coated with a sponge to transfer the paint.
[0010] The coating method of the second aspect of the present invention is characterized in that the outer and inner edges of the frame body are rectangular when viewed from the front, and the vertical dimension of the frame body is 50 cm to 150 cm and the horizontal dimension of the frame body is 50 cm to 150 cm.
[0011] A coating method according to a third aspect of the present invention is characterized in that the thickness of the sponge is 3 cm to 7 cm.
[0012] A coating method according to a fourth aspect of the present invention is characterized in that the coating material is a water-based glass.
[0013] A coating method according to a fifth aspect of the present invention is characterized in that the surface to be coated is a surface finished with mortar. [Effects of the Invention]
[0014] According to the first aspect of the present invention, the stretched silk floss forms a marble-like pattern, and by applying paint to the stretched floss, it is possible to easily apply a marble-like pattern to a painted surface by transferring the paint applied to the floss. Furthermore, since the paint is applied only to the floss portion, the amount of paint used can be reduced, making it possible to inexpensively apply a marble-like pattern. By applying the paint to the backside of the floss, the workability of the application can be improved. Specifically, if paint were to be applied to the front side of the floss, the front side of the floss must be facing up. In this case, most of the floss fixed to the frame is suspended in the frame by the thickness of the frame, causing the floss to bend under the pressure of the brush, making the central portion of the floss particularly difficult to paint. However, when applying paint to the backside of the floss, the front side of the floss can be placed on the ground (via a protective sheet, if necessary) and the paint can be applied to the backside of the floss. This prevents the floss from bending, improving the workability of the application. Furthermore, because the silk floss does not bend, paint can be applied with a brush using an appropriate amount of force, allowing for sufficient paint application. Furthermore, during the brush application process, the stretched silk floss is appropriately twisted, resulting in the thickness of the silk floss streaks being moderately uneven in places, making it possible to apply a natural-looking marble-like pattern with varying thicknesses. Furthermore, before creating the streaky pattern with the stretched silk floss, the area around the streaky pattern can be finely painted with multiple colors, allowing for a natural and beautiful marble-like pattern. Furthermore, since the marble-like streaky pattern is painted with paint applied to the silk floss, the paint to be applied to the silk floss can be selected arbitrarily, allowing the marble-like streaky pattern to be painted in any color. Furthermore, by dividing the painting process into multiple steps and applying different colors of paint to the silk floss in each step, it is possible to paint streaky patterns of different colors. Furthermore, the paint is transferred by pressing the cotton floss in contact with the painted surface from the back with a sponge, and the pressure from the sponge causes the paint applied to the cotton floss to shift or scratch appropriately on the painted surface, making it possible to apply a natural and good marble-like pattern.
[0015] According to the second aspect of the present invention, the frame is formed into a rectangular shape when viewed from the front, which improves the ease of painting and improves work efficiency. Furthermore, since the frame is formed to a predetermined preferred size, the floss wadding to be fixed to the frame must be stretched to an appropriate size so that it can be fixed to the frame. As a result, the floss wadding can be stretched to an appropriate state that allows for the formation of a natural and beautiful marble-like pattern.
[0016] According to the third aspect of the present invention, by using a sponge of a predetermined preferred thickness, the pressure of the sponge when transferring the paint is distributed appropriately, and the strength of the pressure varies depending on the part of the sponge, which results in irregular shades of paint being transferred, making it possible to apply an irregular and good marble-like pattern.
[0017] According to the fourth aspect of the present invention, by using water-based glass as the paint, it is possible to obtain a painted surface with a natural marble-like appearance. Specifically, when a light color is desired, the paint is generally diluted with water, but this reduces the paint ratio, which limits the dilution with water and makes it impossible to achieve a certain level of lightness in color. However, in the case of water-based glass, colorless and transparent water glass is also available, so by diluting the color with this, it is possible to freely paint with light-colored paint without reducing the paint ratio, making it possible to reproduce a more natural marble color.
[0018] According to the fifth aspect of the present invention, the surface to be painted is a surface finished with mortar, so that the painting method of the present invention can be applied to floors, walls, etc. of various buildings and exterior structures. [Brief explanation of the drawings]
[0019] [Figure 1] FIG. 2 is a front view showing an example of a frame according to a preferred embodiment of the present invention. [Figure 2] FIG. 1 is a front view showing an example of a frame to which stretched silk floss is fixed, in a preferred embodiment of the present invention. [Figure 3]FIG. 2 is a rear view showing an example of a frame to which stretched silk floss is fixed, in accordance with a preferred embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0021] The silk floss 1 in the present invention is made by stretching cocoons and turning them into cotton, and is typically a sheet-like silk floss with a height and width of about 15 cm to 25 cm and a thickness of about 0.3 to 0.7 cm.In the present invention, first, a step is carried out to further stretch this silk floss 1, making it into a spider web shape.
[0022] Next, a step is carried out in which the stretched silk floss 1 is fixed to the frame 2. There is no particular limitation on the method for fixing the silk floss 1 to the frame 2, but it can be fixed, for example, by adhesive tape or the like.
[0023] FIG. 1 is a front view showing an example of a frame body 2 according to a preferred embodiment of the present invention. The rear view of the frame body 2 in FIG. 1 appears similar to the front view. The frame body 2 is made of a material having a certain strength, such as wood, resin, or metal, but is not particularly limited thereto. As shown in FIG. 1, the frame body 2 has an open center, and the periphery of the open portion is surrounded by a material such as wood. Although illustrations of a plan view or a side view are omitted, the frame body 2 has a thickness of any desired dimension.
[0024] The shape of the frame body 2 is not particularly limited and can be any shape, but it is preferable that the outer and inner edges of the frame body 2 are rectangular when viewed from the front as shown in Figure 1, as this improves the ease of painting and improves work efficiency.
[0025] The frame 2 is rectangular in front view, and preferably has a vertical dimension (V) of 50 cm to 150 cm and a horizontal dimension (H) of 50 cm to 150 cm, and more preferably has a vertical dimension (V) of 80 cm to 120 cm and a horizontal dimension (H) of 80 cm to 120 cm. By setting the frame 2 to these preferred dimensions, the silk wadding 1 to be fixed to the frame 2 must be stretched appropriately to secure it to the frame 2, thereby enabling the silk wadding 1 to be stretched to an appropriate extent to form a natural and beautiful marble-like pattern. On the other hand, if the frame dimensions are too small, the same frame will have to be placed multiple times on a single surface in different positions during painting. In this case, the same pattern will be painted multiple times on a single surface, resulting in a regular pattern that may be unattractive. On the other hand, if the dimensions of the frame are too large, the frame may become difficult to handle, and the workability of painting may be deteriorated.
[0026] 2 is a front view of the state in which the wadding 1 is fixed to the frame body 2. FIG. 3 is a rear view of the state in which the wadding 1 is fixed to the frame body 2.
[0027] Next, a process is carried out in which paint is applied to the back side of the wadding 1 fixed to the frame 2. Here, "back side" refers to the rear side, the side that appears rear in FIG. 2 and the side that appears front in FIG. 3. The method for applying paint to the wadding 1 is not particularly limited, but it is preferable to apply it with a brush, for example. In the present invention, the paint is applied to the back side of the wadding 1. To apply paint to the front side of the wadding 1, the front side of the wadding 1 must be turned upward. However, since most of the wadding 1 fixed to the frame 2 is floating in the interior by the thickness of the frame 2, the pressure from the brush causes the wadding 1 to bend, making it particularly difficult to paint the central part of the wadding 1. However, when applying paint to the back side of the wadding 1, the front side of the wadding 1 can be grounded (via a protective sheet, if necessary) and the paint can be applied to the back side of the wadding 1. This prevents the wadding 1 from bending, improving the ease of application. Furthermore, because the wadding 1 does not bend, paint can be applied with a brush using just the right amount of force, allowing a sufficient amount of paint to be applied to the wadding 1. In addition, during the application process with a brush, the wadding 1, which has been stretched into stripes, is twisted just enough so that the thickness of the stripes in the wadding 1 becomes just the right amount uneven in places, making it possible to apply a coating with a natural marble-like pattern of stripes with varying thicknesses. As mentioned above, because a sufficient amount of paint can be applied from the back side of the wadding 1, the paint applied from the back side also permeates the front side of the wadding 1, and the paint can be transferred by bringing the front side of the wadding 1 into contact with the surface to be painted.
[0028] The paint applied to the silk floss 1 is not limited, but is preferably water-based glass. Using water-based glass as the paint makes it possible to achieve a painted surface with a natural marble-like appearance. Specifically, when applying a light-colored paint, the paint is generally diluted with water. However, this reduces the paint content, which limits the dilution with water and makes it impossible to achieve a certain level of color lightness. However, in the case of water-based glass, colorless and transparent water glass is also available. By diluting the color with this, it is possible to freely apply light-colored paint without reducing the paint content, thereby reproducing a more natural marble color. For example, water-based glass primarily composed of water glass (potassium silicate), colloidal silica, and inorganic pigments is desirable.
[0029] Next, a step is carried out in which the front side of the coated silk wadding 1 is brought into contact with a surface to be painted. The surface to be painted is not limited, but it is desirable that it be, for example, a surface finished with mortar. If the surface to be painted is a surface finished with mortar, the painting method of the present invention can be applied to floors and walls inside and outside various buildings, as well as floors and walls of exterior structures.
[0030] In the present invention, any commonly used mortar can be used. When the surface to be painted is a floor, for example, a mixture of a powder containing Portland cement, silica powder, silica sand, an organic additive (water-soluble resin), an alkyl acrylate, acrylonitrile, and an aqueous copolymer emulsion with a liquid admixture and water can be used. When the surface to be painted is a wall, for example, a mixture of a powder containing Portland cement, silica sand powder, silica sand, carbon fiber, and a thickener with a liquid admixture that is an acrylic synthetic resin emulsion with water can be used.
[0031] Next, the process of pressing the back side of the silk wadding 1 in contact with the surface to be painted with a sponge is carried out to transfer the paint to the surface to be painted. Here, "back side" refers to the back side, which in Figure 3 means the side that appears at the front (because this is a rear view, the back side appears at the front). In other words, the silk wadding 1 that appears inside the frame 2 in Figure 3 is pressed with a sponge to transfer the paint to the surface to be painted.
[0032] As mentioned above, the silk floss 1 is stretched like a spider's web. By transferring the paint applied to the silk floss 1 to the surface to be painted, the transferred portion forms a marble-like pattern, making it easy to paint a marble-like pattern on the surface. Furthermore, since the paint is applied only to the silk floss 1, the amount of paint used can be reduced, making it possible to inexpensively paint a marble-like pattern. By applying the paint to the backside of the silk floss, the paint application process can be made easier. Specifically, if paint were to be applied to the front side of the silk floss, the front side would need to be facing up. In this case, most of the silk floss attached to the frame would be suspended in the frame by the thickness of the frame. This would cause the silk floss to bend under the pressure of the brush, making it particularly difficult to paint the center of the floss. However, when applying paint to the backside of the silk floss, the front side of the silk floss can be placed on the ground (using a protective sheet, if necessary) and the paint can be applied to the backside of the silk floss. This prevents the silk floss from bending, improving the application process. Furthermore, because the silk floss does not bend, paint can be applied with a brush using an appropriate amount of force, allowing for sufficient paint application. Furthermore, during the brush application process, the stretched silk floss is appropriately twisted, resulting in the thickness of the silk floss streaks being moderately uneven in places, making it possible to apply a natural-looking marble-like pattern with varying thicknesses. Furthermore, before creating the streaky pattern with the stretched silk floss, the area around the streaky pattern can be finely painted with multiple colors, allowing for a natural and beautiful marble-like pattern. Furthermore, since the marble-like streaky pattern is painted with paint applied to the silk floss, the paint to be applied to the silk floss can be selected arbitrarily, allowing the marble-like streaky pattern to be painted in any color. Furthermore, by dividing the painting process into multiple steps and applying different colors of paint to the silk floss in each step, it is possible to paint streaky patterns of different colors. Furthermore, the paint is transferred by pressing the silk floss 1 in contact with the painting surface from the back side with a sponge, and the paint applied to the silk floss 1 is appropriately shifted or scratched on the painting surface by the pressure of the sponge, making it possible to apply a natural and good marble-like pattern painting.
[0033] In the present invention, the sponge preferably has a thickness of 3 cm to 7 cm, more preferably 4 cm to 6 cm. By setting the sponge thickness within this preferred range, the pressure of the sponge when transferring the paint is appropriately distributed, and the strength of the pressure varies depending on the part of the sponge, resulting in irregular shades of paint being transferred, making it possible to apply an irregular, natural, and good marble-like pattern. [Example]
[0034] Four wooden sticks were combined to prepare a frame body, as shown in FIG. 1, which was rectangular in front view, with a vertical dimension (V) of 100 cm and a horizontal dimension (H) of 100 cm.
[0035] A sheet of silk floss about 20 cm high and 20 cm wide and 0.5 cm thick was stretched lengthwise and widthwise to a size that could be fixed to the frame and to form a spider web shape.
[0036] As shown in FIG. 2, the silk floss stretched into a spider web shape was fixed to a frame with adhesive tape (not shown).
[0037] The paint was applied to the back of the cotton wool fixed to the frame using a brush. The paint was a water-based glass that was prepared in advance and whose main components were water glass (potassium silicate), colloidal silica, and inorganic pigments.
[0038] The surface of the painted silk floss was placed in contact with the painted surface. The painted surface was an exterior floor that had been previously finished with mortar. The mortar was made by mixing a powder containing Portland cement, silica powder, silica sand, organic additives (water-soluble resin), alkyl acrylate, acrylonitrile, and copolymer aqueous emulsion with an admixture and water.
[0039] The cotton wool was placed in contact with the painted surface and pressed down from the back with a 5cm thick sponge to transfer the paint.
[0040] As a result of the painting (transfer) in the above manner, an attractive marble-like pattern with irregular, natural patterns and shading was formed on the exterior floor surface. [Example]
