Description

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

As a method of finishing a wall surface, a method of finishing by scraping is known. Scraping can create a variety of expressions depending on the type and mix of aggregates mixed in, and since it is a manual process, it produces a soft finish with fine irregularities on the surface. Because it can express a calm texture and appearance, it is used on the exterior walls of many houses.

Furthermore, as in Patent Document 1, there is a method of patterning a wall surface using a joint material. In Patent Document 1, as shown in FIG. 4(A), a joint material 50 including a release paper 53, a plate-shaped body 52, and an adhesive 51 is pasted on a wall base 10, and a top coat material 30 is applied to the wall base 10. and the surface of the release paper 53 of the joint material 50, and as shown in FIG. Drying the membrane. Recesses are formed by peeling off the release paper 53, and a wall surface having an uneven pattern is formed.

Japanese Patent Application Publication No. 8-120877

In the method of Patent Document 1, since the release paper 53 of the joint material 50 is peeled off while the paint film is wet, the paint film of the top coat material 30 sag, as shown by the broken line circle in FIG. 4(B). In addition, the corners of the convex portions become rounded, making it difficult to form a sharp uneven pattern.

(First form)
The first method of patterning a scraped wall surface consists of a step of pasting a patterning member in which a release part is laminated on an adhesive part to a wall base (patterning member pasting process), and applying a top coat material to the wall base. a process of scraping off the exposed surface of the topcoat material and the mold release part when the coating film of the topcoat material is in a semi-cured state (scraping process); and a process of removing the patterned member ( patterning member removal step).

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

In the patterning member 40a, a release part 42 is laminated on an adhesive part 41. In the patterning member removal process described later, the patterning member 40a is peeled off (removed) from the undercoat material 20, so the adhesive force between the adhesive part 41 and the mold release part 42 is the same as that between the adhesive part 41 and the undercoat material 20. Something stronger than adhesive is used.

The mold release part 42 is made of a material that can be scraped off together with the top coat material 30 in a scraping process described later. Examples of the material for the mold release part 42 include foamed resin made by foaming resin such as polyurethane, polystyrene, and polyolefin. Further, the adhesive portion 41 may be made of known synthetic rubber.

Although the thickness of the patterned member 40a (including the patterned member 40b described later) is not limited, it is preferably 7.0 to 10.0 mm. Furthermore, in the patterned member 40a in which the mold release part 42 is laminated on the adhesive part 41, the thickness of the mold release part 42 is preferably 6.5 to 9.9 mm. Further, as the patterning member 40a (including a patterning member 40b to be described later), for example, one that has an elongated planar shape and is wound in a roll shape can be mentioned. In addition, from the viewpoint of forming a desired uneven pattern on the wall surface, the patterning member 40a (including the patterning member 40b to be described later) may have any shape in which a pattern is desired to be formed as a concave portion when finished, such as a rectangular shape, There is no limit to the shape, such as polygonal shape, circular shape, geometric shape, etc.

(Top coating material application process)
Subsequently, as shown in FIG. 1(C), a top coat material 30 is applied. The top coating material 30 is a coating material for forming a finishing layer on the wall surface. The top coat material 30 can be applied by a known method. The coating method includes a method of coating the entire wall base using a trowel, spatula, spray gun, etc.

The thickness of the top coating material 30 to be applied is preferably approximately the same as the thickness of the patterned member 40 (7.0 to 10.0 mm) from the viewpoint of work efficiency in the scraping process described below. Furthermore, by making the thickness of the topcoat material 30 approximately the same as the thickness of the patterned member 40, the patterned member 40 serves as a guide when applying the topcoat material 30, thereby improving workability in the process of applying the topcoat material. will improve.

The top coating material 30 is not particularly limited as long as it is used as a finishing layer for a general scraped wall surface, and includes, for example, a hydraulic material, aggregate, and water.

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

The aggregate acts as a filler and improves the texture of the formed wall surface. As the aggregate, known aggregates can be used, and examples thereof include silica stone, silica sand, silica powder, diatomaceous earth, talc, clay, agarite (calcium carbonate), zeolite, bentonite, sepiolite, perlite, and the like. By appropriately selecting and using aggregates with different particle sizes, the texture of the formed wall surface can be adjusted.

The top coat material may contain various additives as necessary. Additives include pigments (including liquid pigments), fibers, viscosity modifiers, preservatives, rust preventives, adsorbents, fungicides, curing retarders, deodorants, synthetic resins, dispersants, antifoaming agents, Examples include pH adjusters, leveling agents, etc., and various known and commonly used agents can be appropriately added to these agents.

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

The top coating material can be prepared by adding a predetermined amount of water to a solid powder mixture in which the constituent powder 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 amount of solid mixture and water. The step of adding water to the solid mixture is preferably performed immediately before applying the topcoat material 30 to the wall base 10. Furthermore, if the components are mixed in advance in powder form, storage stability is also good. Furthermore, it is also suitable for the current general product form of wall plastering, which is often used by mixing powdered products in bags with water on site.

(Scraping process)
When the coating film of the top coating material 30 is in a semi-cured state, scraping is performed as shown in FIG. 1(D). Here, the term "semi-cured state" refers to a state in which most of the moisture in the topcoat material has disappeared and the shape of the cured coating film is maintained, but sufficient mechanical strength has not yet been achieved. pointing. To judge the semi-cured state, for example, even if you apply pressure to the topcoat film with your fingertips and rub it, it will not show tackiness, no fingerprint marks will be left, and the paint film will not be deformed. It can also be determined that this condition does not occur.

Scraping can be performed by a general scraping method, and can be performed by finishing by scratching the exposed surfaces of the top coat material 30 and the mold release part 42 using a scraper, a wire brush, etc. . For example, it may be finished by scraping off in a circular shape using a scraper, or by moving in one direction using a wire brush. Note that the scraping may be performed on the entire wall surface or on a portion where the scraped pattern is desired.

As described above, the mold release part 42 is made of a material that can be scraped off, such as foamed resin, so that it can be scraped off together with the coating film of the top coat material 30. Therefore, the boundary between the top coating material 30 and the mold release part 42 can also be scraped off, so that it can be scraped off uniformly.

(Patterning member removal process)
After the scraping process, the patterning member 40a is removed. As shown in FIGS. 1(E) and 2, the pattern is patterned in an uneven manner by the recesses where the undercoat material 20 is exposed by removing the patterning member 40a and the convexes formed by the topcoat material 30. It is possible to finish the wall surface by scraping it off. Here, an example of a wall surface finished by scraping in one direction with a wire brush is shown.

In this manner, in the scraping wall surface patterning method, in addition to the uneven pattern formed by the patterning member 40a, the convex portions are patterned by scraping, so it is possible to realize a wall surface that gives off a variety of expressions. Can be done. Furthermore, by making the undercoat material 20 and the topcoat material 30 different colors, it is possible to finish the wall surface with different colors for the concave portions and convex portions.

In addition, in the scraping process, since the topcoat material 30 is scraped off in a semi-cured state, and the mold release part 42 can also be scraped off together with the topcoat material 30, when the patterning member 40a is removed, the convexes formed are removed. The corners of the portions (the portions indicated by the broken line circles in FIG. 1(E)) have sharp shapes. This makes it possible to finish with a sharp uneven pattern. Further, since the patterned member 40a is removed after the scraping process, the residue of the top coating material 30 generated by scraping does not adhere to the recesses formed on the wall surface.

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

(Patterning member pasting process)
In the patterning member pasting process, the patterning member 40b is pasted on the surface of the wall base 10 shown in FIG. 3(A) as shown in FIG. 3(B). In the second embodiment, a patterned member 40b in which a decorative part 43 is laminated between a releasing part 42 and an adhesive part 41 is used, and a wall base 10 to which no primer material is applied is used. This is different from the first form.

The decorative portion 43 is exposed as a recessed portion of the wall surface and gives an aesthetic appearance to the wall surface. The decorative portion 43 has a plate shape and is made of various materials such as synthetic resin, rubber, and metal. The release part 42 and the decoration part 43 have the adhesive strength between the adhesive part 41 and the wall base 10 and the adhesive strength between the adhesive part 41 and the decoration part 43 so that the release part 42 can be easily peeled off from the decoration part 43. It is attached with a force weaker than the force. The mold release part 42 and the adhesive part 41 are the same as those in the first embodiment described above. In addition, in the patterned member 40b in which the decorative part 43 is laminated between the mold releasing part 42 and the adhesive part 41, the thickness of the mold releasing part 42 is 4.5 to 9.4 mm, and the thickness of the decorative part 43 is 0.5 mm. It is preferably 5 to 2.0 mm.

(Top coating material application process)/(Scraping process)
The topcoat material application step and the scraping step are the same as the topcoat material application step and the scraping step of the first embodiment described above, so the description thereof will be omitted.

(Mold release part removal process)
After the scraping process, as shown in FIG. 3(E), the mold release portion 42 of the patterned member 40b is removed. As a result, it is possible to finish the scraped wall surface with an uneven pattern of concave portions where the decorative portion 43 is exposed and convex portions where the top coat material 30 is exposed. Furthermore, since the convex portions are patterned by scraping, it is possible to create a wall surface with a variety of expressions.

The second form is useful when no primer material is applied to the wall base 10. By making the decorative portion 43 and the top coat material 30 have different colors, it is possible to finish the wall surface with different colors in the concave portions and convex portions. Moreover, since the mold release part 42 of the patterned member 40b is removed after the scraping process, the dregs of the top coating material 30 generated by scraping do not adhere to the recessed part where the decorative part 43 is exposed.

EXAMPLES The present invention will be specifically explained below with reference to Examples, but the present invention is not limited thereto. Note that a gypsum board with a thickness of 9.5 mm was used as the wall base.

(Example 1)
Mix 70 parts by weight of an undercoat material for walls (trade name: Carbon Plaster, manufactured by Shikoku Kasei Kogyo) and 3 parts by weight of liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo) with 44 parts by weight of water. An undercoating material was prepared by pouring it into an aqueous solution that had been colored in advance and mixing it with a mixer until it became uniform. This primer material was applied to the wall base to a thickness of about 1 mm and allowed to dry.

Next, the patterned member was attached to the surface of the base coat material. As a patterning member, one (trade name: Top Backer, manufactured by Sagami Color Foam Kogyo, thickness: 7 mm) whose mold release part was a polyethylene foam 15 times larger 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 placed in a mixer and mixed to produce a powder base material. This powder base material was poured into an aqueous solution that had been colored in advance by mixing 110 parts by weight of water with 5 parts by weight of a liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo), and was uniformly colored with a mixer. A top coat material was prepared by mixing until the mixture was mixed.

This top coat material was applied to the surface of the base coat material other than the patterned member to a thickness equivalent to that of the patterned member (approximately 7 mm thick). Next, after drying for 3 hours, the surfaces (exposed surfaces) of the top coat material and patterned member were scraped off while the top coat material was in a semi-cured state. After that, the patterning member was removed.

In this way, it is possible to form a scraped wall surface that is patterned with convex parts where the top coat material is exposed and concave parts where the base coat material is exposed, and which has different colors for the top coat material and the base coat material. Ta.

(Example 2)
Add 3 parts by weight of liquid pigment (product name: SK Select Color, manufactured by Shikoku Kasei Kogyo) to 40 parts by weight of primer material for plastering walls (product name: Eco Bi Wall Waterproof Type, manufactured by Shikoku Kasei Kogyo), and mix with a mixer. The base coat material was prepared by mixing until uniform. This primer material was applied to the wall base to a thickness of about 1 mm and allowed to dry.

Next, a patterned member similar to that in 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 placed in a mixer and mixed to produce a powder base material. This powder base material was poured into an aqueous solution that had been colored in advance by mixing 110 parts by weight of water with 5 parts by weight of a liquid pigment (trade name: SK Select Color, manufactured by Shikoku Kasei Kogyo), and was uniformly colored with a mixer. A top coat material was prepared by mixing until the mixture was mixed.

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

In this way, it is possible to form a scraped wall surface that is patterned with convex parts where the top coat material is exposed and concave parts where the base coat material is exposed, and which has different colors for the top coat material and the base coat material. Ta.
