Description

The present invention relates to a method of patterning a scraped wall surface.

As a method of finishing a wall surface, a method of finishing by scraping off is known. Scraping off can create various expressions depending on the type and composition of the mixed aggregate, and because it is a manual process, the surface has fine unevenness and a soft finish. It is used for the outer walls of many houses, etc., because it can express a calm texture and appearance.

Moreover, there is a method of applying a pattern to a wall surface using a joint material, as in Patent Document 1.

FIG. 3 is a perspective view of a patterned scraping wall surface; FIGS. 3A to 3E are cross-sectional views for explaining a scraping wall surface patterning method according to the second embodiment. 4A and 4B are cross-sectional views for explaining the method of Patent Document 1. FIG.

(first form)
The scraping wall surface patterning method of the first embodiment comprises a step of attaching a patterning member having a release portion laminated to an adhesive portion to the wall substrate (patterning member pasting step), and applying a topcoat material to the wall substrate. A step of applying the topcoat material (topcoat material coating step), a step of scraping off the exposed surface of the topcoat material and the release portion when the coating film of the topcoat material is in a semi-cured state (scraping step), and a step of removing the patterning member ( Patterning member removing step).

(Patterning member pasting process)
In the patterning member attaching step, a patterning member 40a is attached as shown in FIG. 1(B) to the surface of the wall base 10 shown in FIG. 1(A). Here, since the wall substrate 10 on which the coating film of the undercoat material 20 is formed is used, the surface of the undercoat material 20 is pasted with the patterning member 40a. The undercoat material 20 is not particularly limited as long as it does not hinder the coating film formation of the topcoat material described later, and known materials can be used. Examples of the undercoat material 20 include Carbon Plaster (manufactured by Shikoku Kasei Kogyo Co., Ltd.) and Ecobi Wall Water Resistant Type (manufactured by Shikoku Kasei Kogyo Co., Ltd.). The thickness of the coating film of the undercoat material is, for example, 0.03 to 2.0 mm.

The patterning member 40 a has a release portion 42 laminated on an adhesive portion 41 . Since the patterning member 40a is peeled off (removed) from the undercoat material 20 in the patterning member removing step, which will be described later, the adhesive strength between the adhesive portion 41 and the release portion 42 is the same as that between the adhesive portion 41 and the undercoat material 20. A material stronger than adhesive strength is used.

The release portion 42 is made of a material that can be scraped off together with the topcoat material 30 in the scraping step described later. Examples of the material of the release portion 42 include foamed resin obtained by foaming a resin such as polyurethane, polystyrene, or polyolefin. Further, the adhesive portion 41 may be made of known synthetic rubber.

The thickness of the patterning member 40a (including the patterning member 40b, which will be described later) is not limited, but is preferably 7.0 to 10.0 mm. In the patterning member 40a in which the release portion 42 is laminated on the adhesive portion 41, the thickness of the release portion 42 is preferably 6.5 to 9.9 mm. Further, the patterning member 40a (including the patterning member 40b described later) may be, for example, an elongated planar member wound into a roll. In addition, from the viewpoint of forming a desired uneven pattern on the wall surface, the patterning member 40a (including the patterning member 40b, which will be described later) may have any shape as long as it is desired to form a pattern as a concave portion at the time of finishing, such as rectangular, There are no restrictions on the shape, such as polygonal, circular, or geometric.

(Topcoat material application process)
Subsequently, as shown in FIG. 1(C), a topcoat material 30 is applied. The topcoat material 30 is a coating material for forming the finishing layer of the wall surface. The topcoat material 30 can be applied by a known method. Examples of the method of application include a method of applying to the entire wall substrate using a trowel, spatula, spray gun, or the like.

The thickness of the overcoating material 30 to be applied should be about the same as the thickness of the patterning member 40 (7.0 to 10.0 mm) from the viewpoint of working efficiency in the scraping step described later. In addition, by making the thickness of the topcoat material 30 about the same as the thickness of the patterning member 40, the patterning member 40 serves as a guide when applying the topcoat material 30, so the workability of the topcoat material application process improves.

The topcoat material 30 is not particularly limited as long as it is used as a finish layer for general scraped wall surfaces, and includes, for example, a hydraulic material, aggregate, and water.

A hydraulic material is a material that hardens upon reaction with water. The hydraulic material functions as a binder and is not particularly limited as long as it has coating film forming ability, and known materials can be used. Examples of hydraulic materials include cement, gypsum (hemihydrate gypsum, calcined gypsum), and hydraulic lime. These may be used alone or in combination of two or more.

Aggregate functions as a filler and improves the texture of the walls formed. Known aggregates can be used, and examples thereof include silica stone, silica sand, silica powder, diatomaceous earth, talc, clay, cold water stone (calcium carbonate), zeolite, bentonite, sepiolite, and perlite. By appropriately selecting and using aggregates having different particle sizes, the texture of the formed wall surface can be adjusted.

Top coat material may contain various additives as needed. Additives include pigments (including liquid pigments), fibers, viscosity modifiers, preservatives, rust inhibitors, adsorbents, fungicides, curing retardants, deodorants, synthetic resins, dispersants, antifoaming agents, pH adjusters, leveling agents and the like can be mentioned, and these can be used by appropriately adding various known and commonly used ones.

The blending amount of the hydraulic material is preferably 10 to 50% by weight, more preferably 10 to 35% by weight, based on the total solid components excluding water, from the viewpoint of workability and the like. Also, the amount of the aggregate to be blended is preferably 50 to 90% by weight, more preferably 65 to 90% by weight, based on the total solid components excluding water, from the viewpoint of workability and the like. Moreover, the mixing ratio of various additives can be added within a range that does not affect the effects of the present invention.

The topcoat material can be prepared by adding a predetermined amount of water to a powdery solid mixture in which the constituent powdery components are uniformly mixed. The amount of water is usually 10% to 50% by weight, preferably 20% to 40% by weight, based on the total weight of the solid mixture and water. The step of adding water to the solid mixture is preferably performed immediately before the topcoat material 30 is applied to the wall substrate 10 . Moreover, if each component is mixed in advance in a powder state, the storage stability is good. Furthermore, it is also suitable for current general wall plaster products, which are often used by kneading the product packed in a powder state with water on site.

(Scraping off process)
When the coating film of the topcoat material 30 is in a semi-cured state, it is scraped off as shown in FIG. 1(D). Here, the "semi-cured state" refers to the state in which the water content of the topcoat material has almost disappeared and the shape of the coating film formed by curing is maintained, but sufficient mechanical strength has not yet been obtained. pointing. As a judgment of the semi-cured state, for example, even if the coating film of the topcoat material is pressed or rubbed with a fingertip, it does not show stickiness, does not leave fingerprint marks, and does not deform the coating film. It can be judged as a state in which neither occurs.

The scraping can be performed by a general scraping method, and can be performed by using a scraper, a wire brush, or the like to scratch and finish the exposed surfaces of the topcoat material 30 and the release portion 42. . For example, a scraper may be used to scrape off in a circular shape, or a wire brush may be used to move in one direction to finish. The scraping may be performed on the entire wall surface, or may be performed on a part of the wall where the scraping pattern is desired.

Since the release part 42 is made of a material that can be scraped off, such as foamed resin, as described above, it can be scraped off together with the coating film of the topcoat material 30 . Therefore, since the boundary portion between the overcoat material 30 and the release portion 42 can also be scraped off, the scraping can be uniformly performed.

(Process for removing patterning member)
After the scraping process, the patterning member 40a is removed. As shown in FIGS. 1(E) and 2, by removing the patterning member 40a, the patterning is applied in an uneven shape by the recesses where the undercoat material 20 is exposed and the protrusions formed by the topcoat material 30. It can be finished on the scraped wall surface. Here, an example of a wall surface finished by scraping off in one direction with a wire brush is shown.

In this way, in the scraped-off wall surface patterning method, in addition to the concave-convex pattern formed by the patterning member 40a, a pattern is added to the convex portions by scraping off, so that a wall surface with a variety of expressions can be realized. can be done. Furthermore, if the colors of the undercoat material 20 and the topcoat material 30 are made different, it is possible to finish the wall surface with different colors in the concave portions and the convex portions.

In addition, in the scraping step, since the topcoat material 30 is scraped off in a semi-cured state, and because the release part 42 can be scraped off together with the topcoat material 30, when the patterning member 40a is removed, the convexes formed The corners of the part (the portion of the dashed circle shown in FIG. 1(E)) have a sharp shape. As a result, a sharp uneven pattern can be finished. Further, since the patterning member 40a is removed after the scraping step, the residue of the overcoat material 30 generated by the scraping does not adhere to the concave portions formed on the wall surface.

(Second form)
The scraping-off wall patterning method of the second embodiment includes a step of attaching a patterning member having a decorative portion laminated between a release portion and an adhesive portion to a wall substrate (patterning member pasting); A step of applying the topcoat material to the wall base (topcoat material application step), and a step of scraping off the exposed surface of the topcoat material and the release portion when the coating film of the topcoat material is in a semi-cured state (scraping step); and a step of removing the release portion (release portion removal step).

(Patterning member pasting process)
In the patterning member attaching step, a patterning member 40b is attached as shown in FIG. 3(B) to the surface of the wall base 10 shown in FIG. 3(A). In the second embodiment, the patterning member 40b in which the decorative portion 43 is laminated between the release portion 42 and the adhesive portion 41 is used, and the wall substrate 10 to which the undercoat material is not applied is used. is different from the first form.

The decorative portion 43 is exposed as a concave portion of the wall surface and gives the wall surface a beautiful appearance. The decorative portion 43 is plate-shaped and made of various materials such as synthetic resin, rubber, and metal. The release portion 42 and the decoration portion 43 are formed by the adhesion force between the adhesive portion 41 and the wall base 10 and the adhesion between the adhesion portion 41 and the decoration portion 43 so that the release portion 42 can be easily peeled off from the decoration portion 43 . It adheres with a force weaker than the force. The release portion 42 and the adhesive portion 41 are the same as in the first embodiment described above. In the patterning member 40b in which the decorative portion 43 is laminated between the release portion 42 and the adhesive portion 41, the thickness of the release portion 42 is 4.5 to 9.4 mm, and the thickness of the decoration portion 43 is 0.4 mm. It is preferably 5 to 2.0 mm.

(top coating material application process) (scraping off process)
Since the topcoat material application process and the scraping process are the same as the topcoat material application process and the scraping process of the above-described first embodiment, descriptions thereof are omitted.

(Release portion removing step)
After the scraping step, as shown in FIG. 3(E), the release portion 42 of the patterning member 40b is removed. As a result, it is possible to finish the scraped-off wall surface patterned unevenly by the concave portion where the decorative portion 43 is exposed and the convex portion where the overcoating material 30 is exposed. Furthermore, since the convex portions are patterned by scraping off, it is possible to realize a wall surface that brings out various expressions.

The second form is useful when the undercoat material is not applied to the wall base 10 . By using different colors for the decorative portion 43 and the topcoat material 30, it is possible to finish a wall surface having different colors for the concave portion and the convex portion. In addition, since the release portion 42 of the patterning member 40b is removed after the scraping step, the residue of the overcoat material 30 generated by the scraping does not adhere to the concave portion where the decorative portion 43 is exposed.

EXAMPLES The present invention will be specifically described below with reference to Examples, but the present invention is not limited to these. A gypsum board having a thickness of 9.5 mm was used as the wall substrate.

(Example 1)
70 parts by weight of undercoat material for painted walls (trade name: Carbon Plaster, manufactured by Shikoku Kasei Kogyo Co., Ltd.) was mixed with 44 parts by weight of water and 3 parts by weight of liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo Co., Ltd.). It was put into an aqueous solution that had been colored in advance using a mixer, and mixed until uniform with a mixer to prepare an undercoat material. This undercoat material was applied to the wall substrate in a thickness of about 1 mm and dried.

The patterning member was then applied to the surface of the base coat. As the patterning member, a release part having a 15-fold polyethylene foam (trade name: Top Backer, manufactured by Sagami Color Foam Industry Co., Ltd., thickness: 7 mm) was used.

Thereafter, 135 parts by weight of calcined gypsum, 270 parts by weight of calcium carbonate, 22.5 parts by weight of zeolite, and 22.5 parts by weight of re-emulsified acrylic powder resin were mixed in a mixer to prepare a powder base material. This powdery base material is added to an aqueous solution that has been pre-colored by mixing 5 parts by weight of a liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo) with 110 parts by weight of water, and is uniformly mixed with a mixer. A topcoat material was prepared by mixing until it was

This overcoat material was applied to the surface of the undercoat material other than the patterning member in a thickness equivalent to that of the patterning member (thickness of about 7 mm). Next, after drying for 3 hours, the surfaces (exposed surfaces) of the topcoat material and the patterning member were scraped off while the topcoat material was in a semi-cured state. The patterning member was then removed.

In this way, it is possible to form a scraping wall surface patterned with a convex portion where the topcoat material is exposed and a concave portion where the undercoat material is exposed, and with different colors for the topcoat material and the undercoat material. rice field.

(Example 2)
Add 3 parts by weight of liquid pigment (product name: SK Select Color, made by Shikoku Kasei Kogyo) to 40 parts by weight of undercoat material for painted walls (product name: Ecobi Wall / Water Resistant Type, made by Shikoku Kasei Kogyo) and mix with a mixer. The primer was prepared by mixing until uniform. This undercoat material was applied to the wall substrate in a thickness of about 1 mm and dried.

Then, a patterning member similar to that of Example 1 was attached to the surface of the undercoat material.

Thereafter, 135 parts by weight of calcined gypsum, 270 parts by weight of calcium carbonate, 22.5 parts by weight of zeolite, and 22.5 parts by weight of re-emulsified acrylic powder resin were mixed in a mixer to prepare a powder base material. This powdery base material is added to an aqueous solution that has been pre-colored by mixing 5 parts by weight of a liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo) with 110 parts by weight of water, and is uniformly mixed with a mixer. A topcoat material was prepared by mixing until it was

This overcoat material was applied to the surface of the undercoat material other than the patterning member in a thickness equivalent to that of the patterning member (thickness of about 7 mm). Next, after drying for 3 hours, the surfaces (exposed surfaces) of the topcoat material and the patterning member were scraped off while the topcoat material was in a semi-cured state, and then the patterning member was removed.

In this way, it is possible to form a scraping wall surface patterned with a convex portion where the topcoat material is exposed and a concave portion where the undercoat material is exposed, and with different colors for the topcoat material and the undercoat material. rice field.
