Description

[Technical field]

[0001] The present disclosure relates to a facing material used for finishing wall surfaces such as interior and exterior wall surfaces of structures such as buildings, and a method for finishing a wall surface using the facing material, and the field of application thereof is the architectural field. [Background technology]

[0002] Many types of facing materials have been proposed for use in finishing walls, and representative examples of these are those described in Japanese Patent Application Laid-Open Nos. 2000-42484 and 2001-259516.

[0003] First, JP 2000-42484 A describes a striped color pattern surface material in which multiple colored coating materials containing different colored aggregates are mixed together to form a striped pattern, and at the color boundaries of the striped pattern, the colored aggregates are mixed and distributed with a density gradient to form a striped color pattern in which the color boundaries change gradually, and the striped color pattern is formed so as to penetrate from the surface to the bottom of the coating layer. This makes it possible to obtain a striped color pattern surface material which is free from the problems associated with surface printing methods and can freely express a blurred striped color pattern reminiscent of natural stone in any desired pattern.

[0004] Furthermore, the coating composition described in JP 2001-259516 A comprises a substrate and a paint layer formed on the substrate, in which linear or strip-like convex portions are formed on at least a part of the surface of the paint layer, the inside of the paint layer is formed in a particulate form, and the convex portions and concave portions formed between the multiple convex portions form an uneven shape on the surface of the paint layer. This makes it possible to obtain a striped pattern on the surface of the paint layer, thereby providing a good appearance. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2000-42484 A [Patent Document 2] JP 2001-259516 A Summary of the Invention [Problem to be solved by the invention]

[0006] By using such a facing material, it is possible to improve the finish of the walls of the interior and exterior walls of a structure such as a building. However, the surface material described in Patent Document 1 has a smooth surface on which multiple colored paint materials are applied in stripes, so it does not emphasize the thickness of the surface material and has a poor design feel.

[0007] In addition, in JP 2001-259516 A, the inside of the paint layer is formed in a particulate form, which can limit the design of the covering material and can make it impossible to effectively use the convex shape of the surface material. The present disclosure provides a surface material with a textured design in which a pattern portion formed from a single coating material has a pattern of multiple directional concave and / or convex stripes that emphasize the pattern, and provides a method for finishing walls that makes full use of the pattern. [Means for solving the problem]

[0008] This is a facing material used for surface finishing of buildings and other structures, which is composed of a base material and a pattern portion formed with a single coating material, and the pattern portion is formed with a plurality of directional concave and / or convex stripes. This emphasizes the pattern and gives the product a design with a sense of texture.

[0009] This is a finishing method for performing surface finishing of a structure using a plurality of sheets of the above-described facing material, in which the facing materials are arranged with a gap of 3 to 10 mm between adjacent facing materials. This allows the patterns to be separated from adjacent mounting materials, highlighting the directional multiple concave and / or convex stripes of one mounting material, and making full use of the textured design pattern.

[0010] The joints between adjacent facing materials, spaced 3 to 10 mm apart, are filled with a coating material with a pattern formed thereon to a thickness greater than the thickness of the facing material. This makes it possible to distinguish the patterns of adjacent mounting materials, highlights the directional multiple concave and / or convex patterns of a single mounting material, and allows a wall surface, etc., to be finished while making full use of the textured design pattern and to obtain a unified textured finish as a whole.

[0011] The orientation of the multiple concave and / or convex stripes in the pattern portion of the covering material is the same. This makes it possible to separate the patterns of adjacent mounting materials, fully utilize the textured design pattern of the directional multiple concave and / or convex stripes of one mounting material, and achieve a finished wall surface, etc., with a unified texture as a whole.

[0012] The direction of the multiple concave and / or convex stripes of the pattern part of the facing material is the same, and the joints between adjacent facing materials are spaced 3 to 10 mm apart, and the coating material forming the pattern part is filled in a thickness greater than the thickness of the facing material, and after filling, a pattern of multiple concave and / or convex stripes having the same direction as the pattern part is formed. This allows the finished wall surface to have a sense of unity as a whole and a textured finish. [Brief description of the drawings]

[Figure 4]1 to 3. FIG. [Diagram 5] The photo shows sheet-type joint material pasted onto a wall surface in a grid pattern. [Figure 6] The cross section shows a wall surface to which a facing material and sheet-like joint material have been attached, with the coating material being filled to a thickness greater than or equal to the facing material. [Figure 7] The coating material is applied, and the trowel is moved in the same direction as the pattern, causing the aggregate in the coating material to roll, and the pattern is formed using the trajectory of the aggregate. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An embodiment of the present disclosure will be described. The present disclosure relates to a surface material used for surface finishing of structures such as buildings, which is composed of a base material and a pattern portion formed by a single coating material, and the pattern portion is formed with a plurality of directional concave stripes, convex stripes, or both. First, the covering material used in the present disclosure has a pattern portion laminated on the surface side of a base material using a single coating material, and the pattern formed by the coating material is a directional pattern formed by multiple concave stripes, convex stripes, or both.

[0015] This covering material is applied to finish the interior and exterior walls of architectural structures, as well as to the columns, beams, ceilings, etc. of architectural structures, providing protection and adding a decorative element, and is generally rectangular or square in shape. This facing material is preferably flexible, so that it can be used on curved wall surfaces and round pillars, and can follow the movement of the finished surface to which it is attached over time, with fewer defects such as cracks.

[0016] The surface material is preferably 1200×1200 mm or less in size from the standpoint of ease of application to the wall surface and design considerations, and its weight is preferably in the range of 1.0 to 10.0 kg per square meter. With this weight per square metre, the multiple concave and / or convex stripes in the covering material will create a directional pattern that is firm, creating a voluminous design and allowing the material to be applied without shifting.

[0017] The flexibility of this facing material is determined by bending it along a cylinder with a diameter of 60 cm and checking whether or not cracks or other breaks occur on the surface of the facing material, and this is deemed to be normal. The thickness of this covering material is preferably in the range of 1.0 to 5.0 mm at the thickest part. If it is thinner than 1.0 mm, the directional concave and / or convex stripes of the pattern portion 12 may not be sufficient, resulting in a poor texture.

[0018] If the thickness is more than 5.0 mm, the concave and / or convex patterns may not be distinct, resulting in poor texture. Also, the weight of the covering material 11 may become heavy, which may reduce the efficiency of application work. The size is more preferably in the range of 300 to 900 mm. If it is within this range, the handling and construction properties, and the design of the finished wall surface will be good.

[0019] A typical example of this type of covering material is covering material 11 as shown in Figure 1, which has a pattern portion 12 on the front side and a base portion 13 on the back side for supporting pattern portion 12, with pattern portion 12 having a horizontally directional pattern formed by a number of both concave and convex stripes formed by a coating material. This pattern portion 12 represents the design of the finished wall surface, and is often formed on the base material portion 13 with a trowel or pattern roller used in plastering or painting work.

[0020] A coating material generally used in painting can be used to form the pattern portion 12, but the coating film must be flexible after drying. Preferably, the coating material can be thickened. Examples include thickly applied pattern materials that use synthetic resin as a binder, coating materials that contain a large amount of filler in the paint, and colored aggregate-containing coating materials that are made by mixing natural stone or crushed stone, colored aggregate, colored plastic granules, or crushed plastic granules with synthetic resin emulsion or solvent-based synthetic resin.

[0021] The synthetic resins used in the pattern materials, paints, coating materials, etc. include various acrylic ester copolymers, styrene-acrylic ester copolymers, Veova acrylic ester copolymers, SBR latex, urethane resins, epoxy resins, etc., and at least one of these polymers is appropriately selected and used. The base material 13 supports the pattern portion 12, but also has the effect of adjusting the absorption of adhesive or glue when the covering material 11 is attached to a wall surface with an adhesive or glue. The base material 13 is also an important element for improving the tensile, bending, and tear strength of the covering material 11 as a whole.

[0022] The base material 13 can be a relatively thin material such as woven fabric, nonwoven fabric, glass cloth, ceramic paper, synthetic paper, or any of these that have been sealed; a plastic or metal plate; or polymer cement mortar molded into a sheet. Among these, flexible woven fabrics, nonwoven fabrics, glass cloth, ceramic paper, synthetic paper, and the like, as well as materials having a relatively thin thickness of 1 mm or less, are preferably used.

[0023] This makes it easier to obtain a flexible covering material 11 and to handle it. It also makes it easier to handle when forming the patterned portion 12, which will be described later. Furthermore, by performing the sealing treatment, adhesion to the coating material is improved, and the strength of the base material portion 13 is improved. The covering material 11 can be obtained by applying a coating material or the like that will become the pattern portion 12 to the base material portion 13, drying and hardening it, and laminating and compounding it.

[0024] There are no particular limitations on the method of drying and hardening, and examples of the method include natural drying, in which the covering material 11 with the undried pattern portion 12 is left to dry naturally, and forced drying, such as by heating with a far-infrared oven, hot air heating, or electric heating. The drying method may be any method that sufficiently dries the undried pattern portion 12, and a combination of these methods may be used, with an efficient drying method being appropriately selected.

[0025] In the present disclosure, the pattern portion 12 is formed using a single coating material described above. By forming the pattern portion 12 using a coating material of a single color in this manner, the directional multiple concave and / or convex stripes of the pattern portion 12 can be emphasized more than when multiple colors are used, resulting in a design with texture. In addition, when filling the joints between adjacent covering materials 11 (described below) with a coating material having a pattern portion 12 formed thereon to a thickness greater than the thickness of the covering material 11, the coating material to be filled is also a single color coating material, making the filling operation easy to carry out.

[0026] This further separates the patterns of the adjacent mounting materials 11, makes the directional pattern of one mounting material 11 stand out more, and makes it possible to obtain a wall surface or the like that is finished while making full use of the textured design pattern and has a unified textured finish as a whole. Furthermore, by filling the joints with a coating material forming the patterned portion 12 to a thickness greater than the thickness of the facing material, and then forming a pattern of multiple concave and / or convex stripes having the same directionality as the patterned portion 12 after filling, it is possible to obtain a finished wall surface with a textured finish that has a sense of unity as a whole.

[0027] The pattern portion 12 can be formed by applying the coating material described above to the surface of the base material 13 and applying the coating material in a specific direction to create a pattern. The spacing between the multiple directional concave and / or convex stripes may be equal or random, and it is preferable that the spacing be different from the spacing or spacing width between adjacent covering materials 11 described below.

[0028] This makes it possible to further emphasize the pattern of the multiple directional concave and / or convex stripes of the pattern portion 12. As an example of a method for forming this pattern portion 12, a plastering trowel or spatula can be used to apply the coating material in one direction, such as the vertical or horizontal direction, of the base material portion 13, thereby obtaining a pattern portion 12 with a striped pattern of uneven stripes.

[0029] This is a comb trowel with a part having an uneven shape, and the pattern part 12 is formed using the rectangular uneven part. If the shape is triangular, a striped pattern of uneven stripes that matches the shape can be formed. A typical example is a mounting material 11 shown in Fig. 2. This mounting material 11 has a pattern portion 12 formed using a comb trowel with triangular teeth.

[0030] By forming the pattern portion 12 in this manner, the weight of the coating material applied becomes almost constant, and the weight and thickness of the covering material 11 and the shape of the pattern portion 12 become almost constant, making it possible to obtain a stable covering material 11. The spacing between the multiple concave and / or convex stripes of this pattern portion 12 is one method for forming a pattern with approximately equal spacing when a plastering trowel or spatula is used, and a pattern portion 12 with a striped pattern of equally spaced concave and convex stripes can be obtained.

[0031] Another method is to mix aggregate into the coating material in a size that is approximately the thickness of the required pattern portion 12, and then smooth the coating material containing the aggregate in a certain direction, causing the aggregate to roll and form a pattern in the form of the aggregate's path. In this case, a pattern with a certain directionality can be formed by spreading the coating material containing aggregate horizontally, vertically, diagonally, etc. toward the base material 13. Also, by rotating it in a circular shape, it is possible to form a pattern of circular aggregate trajectories.

[0032] A representative example is the facing material 11 shown in Figure 1. This is made by mixing aggregate into the coating material to a thickness equivalent to that of the facing material, dragging it horizontally with a trowel, and forming a pattern by the random trail of the aggregate dragged in a certain direction. By forming the pattern portion 12 in this manner, the thickness of the mounting material 11 becomes almost constant, and the weight of the mounting material 11 also becomes almost constant, making it possible to obtain a stable mounting material 11.

[0033] In the case of the covering material 11 as shown in FIG. 1, aggregate of a size approximately equal to the thickness of the required pattern portion 12 is mixed into the coating material, and the coating material containing the aggregate is smoothed in a certain direction, causing the aggregate to roll and form a pattern in the form of the aggregate's trajectory. This is one method that can effectively obtain a random pattern. Furthermore, among the painting rollers, it is also possible to use a pattern roller that applies a directional pattern such as ripples to obtain the directional pattern portion 12. Depending on the painting direction of this pattern roller, it is possible to obtain a pattern portion 12 with a certain directionality such as horizontal, vertical, or diagonal.

[0034] A representative example is the covering material 11 shown in Figure 3. This is a material in which a wave pattern is formed using a pattern roller, and by rolling the pattern roller in a certain direction, a directional wave pattern can be formed. By forming the pattern portion 12 in this manner, the amount of coating material applied becomes almost constant, the thickness of the mounting material 11 tends to fall within a certain range, and the weight of the mounting material 11 is stable and within a certain range.

[0035] Furthermore, with the covering material 11 as shown in FIG. 3, even when a pattern roller that creates a directional pattern such as wavy stripes is used, it is possible to form a random pattern that is nearly equally spaced. The covering material 11 having the pattern portion 12 formed thereon in such a manner is cut to a required size and attached to a wall surface or the like for use in finishing.

[0036] There are no particular limitations on the cutting method, and it is possible to use a straight cutter or a press machine, a blade, or a cutter knife or scissors. In particular, when the covering material 11 is applied, it may be cut to the required dimensions immediately before application, and a cutter knife or the like is often used for cutting during the application process.

[0037] It is also preferable to provide a clear layer on the surface of the mounting material 11. By providing this clear layer, it becomes possible to make the mounting material surface less susceptible to dirt and to make the mounting material surface soft to the touch. This clear layer can be easily formed by applying a clear coating, and the thickness of the clear layer can be easily adjusted by adjusting the amount of coating.

[0038] By adjusting the thickness of this clear layer, the feel can also be adjusted; for example, a thick clear layer can be used for parts that are touched by the hands, allowing for a wall finish that feels soft to the touch. The type of clear coating material is not limited, but includes glossy clear, matte clear, transparent color clear, etc., and these can be used to form a clear layer using a coating method such as a roll coater, curtain coater, or airless spray coating.

[0039] Furthermore, the color tone of the pattern portion 12 and the base material portion 13 may be the same color or different colors. This means that the color of the coating material forming the pattern portion 12 after drying is the same color or different color as the base material portion 13. Regarding the color of the base material 13, when the base material 13 is filled, the filling material may be colored and used to color the base material.

[0040] When the pattern portion 12 and the base material portion 13 are of the same color, if the concave stripe pattern portion of the pattern portion 12 becomes thin or if no coating film is formed, the base material portion 13 will show through; however, since the base material portion 13 is of the same color as the pattern portion 12, it is possible to obtain a covering material 11 that is a single color overall.

[0041] When the pattern portion 12 and the base portion 13 are different colors, if the thickness of the concave stripe pattern portion of the pattern portion 12 is sufficient so that it does not show through the base portion 13, the overall color will be uniform. When the coating film becomes thin or when no coating film is formed, the base material 13 is visible and the pattern of the grooves takes on the color of the base material 13, resulting in a distinctive pattern portion 12.

[0042] A preferred embodiment of the covering material 11 shown in Figures 1 to 3 is one in which the back surface has adhesive portions 21 on all four sides, as shown in Figure 4, and the adhesive portions 21 are protected by release paper portions 22. By adopting this configuration, when applying the adhesive described below to the back surface of the covering material 11, there is no need to apply it all the way to the edges of the covering material 11, and since the adhesive processed portion 21 is protected by the release paper portion 22, when the covering material 11 is attached to a wall surface in this state, the release paper portion 22 can be peeled off while the covering material 11 is attached.

[0043] In addition, there is no overflow of the adhesive from the end of the mounting material 11, so that a good finish can be obtained, and the mounting material 11 does not shift during the time until the adhesive hardens and dries, so that the mounting material can be reliably adhered. Furthermore, when a sheet-like joint material described below is used, the sheet-like joint material can be attached to the adhesive processed portion 21, allowing the four sides of the covering material 11 to be fixed more firmly and instantly to the wall surface.

[0044] The width of this adhesive processed portion 21 is preferably in the range of 5 to 30 mm, and within this range, the end portion of the covering material 11 can be sufficiently adhered, and the adhesive of the adhesive processed portion 21 is not particularly limited, and any known adhesive can be used. Representative examples of such rubbers include acrylic rubber and non-vulcanized butyl rubber, which are particularly preferred due to their ease of availability, as well as silicone rubber, styrene butadiene rubber, polyisoprene, and polyvinyl ether.

[0045] The release paper portion 22 can be made of paper coated with fluororesin or silicone resin, which is a known material usually used for adhesive tapes, labels, etc. Tapes in which the adhesive processing portion 21 and the release paper portion 22 are integrated are preferably used because they simplify processing. This type of tape includes double-sided tape, and can be processed by attaching an adhesive portion 22 and release paper 21 integrated together to the back surface of the covering material 11 using adhesive on the other side.

[0046] Other than using double-sided tape, there is a method in which an adhesive is applied to a certain width to form an adhesive processed portion 21, and then the adhesive processed portion 21 is covered and protected with a release paper portion 22. The covering material 11 constructed as described above is finished by combining a plurality of sheets. In the finishing process, the sheets are often attached with an adhesive.

[0047] The walls to be finished in this way are often made up of multiple pieces of concrete, mortar, metal, wood, glass, wallboard, panels, etc. These wallboard materials include ceramic siding boards, flexible boards, calcium silicate boards, extruded boards, wood chip cement boards, precast concrete boards, lightweight aerated concrete boards, and gypsum boards, as well as wallboard materials made from metal materials such as aluminum, iron, and stainless steel.

[0048] Furthermore, some panels are made of a plurality of base materials or wallboard materials and have decorative surfaces. Among these wall surfaces, in the case of wall surfaces that are composed of multiple wall boards or panels, or painted surfaces that have been painted with paint or the like, or in the case of wall surfaces that have an existing finished surface with fixed objects such as tiles attached, the flexible covering material 11 described above is preferred.

[0049] This prevents cracks from occurring on the wall surface due to movement of the structure, and in some cases reduces the risk of the wall panels and tiles that make up the wall surface falling off. This covering material 11 can be attached using an adhesive, and although there is no particular limitation on the adhesive, various adhesives such as synthetic rubber, vinyl acetate, polymer cement, acrylic rubber, and modified silicone can be used.

[0050] The adhesives and the like may be in the form of a solvent-based type that uses an organic solvent as a solvent, a water-based type that uses water, or a solventless type that does not use either of these. From the viewpoint of the working environment, the water-based and solventless types are preferably used. This adhesive is applied to the wall surface and the covering material 11 is attached. This adhesive is often applied with a spatula, trowel, or a paint roller used for painting, and by using these tools, the work can be carried out efficiently.

[0051] This facing material 11 is applied to the wall surface to be finished using an adhesive, which is applied by applying it to the front surface of the wall surface or the back surface of the facing material 11. The adhesive can be applied to either surface, and the surface that is easiest for the worker to work on is used as the application surface, and the adhesive is applied thereto. A plurality of sheets of this facing material 11 are used to perform surface finishing of a structure, and the facing materials 11 are arranged with an interval between adjacent facing materials 11 in the range of 3 to 10 mm.

[0052] This allows the patterns of adjacent mounting materials 11 to be separated, highlighting the directional patterns of a plurality of concave and / or convex stripes of one mounting material 11, and providing a finish that fully utilizes the textured design pattern. Furthermore, the 3 to 10 mm gap between adjacent facing materials 11 can be used as a joint, making it possible to obtain a better finished wall surface.

[0053] If the distance between adjacent mounting materials 11 is less than 3 mm, it may be difficult to distinguish the recessed stripe pattern of the pattern portion 12 of the mounting material, and the pattern of the mounting material 11 may not be highlighted. If it is wider than 10 mm, the spacing will be too wide and will be too noticeable, making it impossible to make the pattern of the covering material 11 stand out.

[0054] More preferably, the spacing is in the range of 4 to 6 mm, so that the directional multiple concave and / or convex stripes of the pattern portion 12 of the covering material 11 stand out, and the spacing between adjacent covering materials 11 forms a joint that gives an attractive finish. When using this gap as a joint, the wall surface can be left exposed as it is, or the adhesive used to attach the facing material 11 can be allowed to protrude to form a joint, or the part to be used as a joint can be colored with paint or the like before the facing material 11 is attached, or the gap can be colored with paint or the like after the facing material 11 is attached.

[0055] When coloring these gaps, it is possible to use paint or sealant that has a waterproof effect. As another preferred method, a sheet that has been subjected to a sealing treatment used for the base material portion 13 is used as a sheet-like joint material, which is attached to the area corresponding to the gap between adjacent facing materials 11, and the sheet-like joint material is exposed at intervals of 3 to 10 mm.

[0056] Among these methods, a more preferred method is to apply a sheet-like joint material wider than the exposure interval before applying the covering material 11, and then apply the covering material 11 while overlapping it on the surface of the sheet-like joint material. This type of overlapping is preferred because it improves the waterproofing performance of the finished wall surface and allows for a beautiful finish.

[0057] Furthermore, it is possible to easily impart properties such as waterproofness, moisture permeability, and stain resistance to this sheet-like joint material by using a sealing material or the like. This sheet-like joint material, if it is flat, can be folded before application, so it can be easily processed into shapes such as protruding corners and recessed corners, which are common at the ends of walls, and can be applied to fit the shape of corners such as protruding corners and recessed corners, allowing for efficient work.

[0058] The width of this sheet-like joint material is preferably in the range of 20 to 100 mm. If it is narrower than 20 mm, the overlap with the facing material 11 will be insufficient, and waterproofing performance may be inferior. If it is wider than 100 mm, application will be time-consuming and it may be difficult to fit it with the finishing material later. Furthermore, the thickness of this sheet-like joint material is preferably less than 1 mm. If it is thicker than 1 mm, when it is overlapped with the facing material 11, a step will be created between the surface of the facing material 11 and the base, and this step may result in a poor finish by the facing material 11.

[0059] Even if this step is to be eliminated, if the step is large, exceeding 1 mm, the task becomes time-consuming and difficult. When the sheet joint material is thin (less than 1 mm) and flexible, it can be rolled up and cut to any length for use, allowing for efficient work.

[0060] Next, this wall finishing method is performed on a smooth surface to be finished, and if necessary, a smooth wall surface is prepared before finishing. For example, if the wall surface is concrete, a base preparation material containing cement as the main component is used, and the wall surface is prepared by smoothing it with a metal trowel or the like. Furthermore, if necessary, a primer treatment or the like can be carried out, which is preferably carried out since it can improve adhesion between the wall surface and adhesives for attaching facing materials or sheet-like joint materials, or coating materials used to fill the gaps between adjacent facing materials.

[0061] For this primer treatment, a general primer such as an aqueous primer containing an acrylic synthetic resin emulsion as a main component can be used, and there is no particular limitation. After preparing the wall surface for finishing in this way, the positions where the facing materials will be applied are marked, and the facing materials are applied so that the intervals between adjacent facing materials are within the range of 3 to 10 mm.

[0062] Furthermore, when the sheet-like joint material described above is applied before the finishing of the facing material, the position where the sheet-like joint material is applied is marked taking into consideration the position where the facing material 11 is applied. The sheet-like joint material is affixed to the marked positions, and in attaching the sheet-like joint material, the adhesive used for attaching the facing material 11 is applied in a similar manner, the sheet-like joint material is affixed, and then the facing material 11 is attached to finish the wall surface.

[0063] In this manner, by using multiple sheets of mounting material 11 and arranging adjacent mounting materials 11 with a gap of 3 to 10 mm between them, the patterns of adjacent mounting materials 11 can be divided by that gap, highlighting the pattern of multiple directional concave and / or convex stripes on a single mounting material, and making full use of the textured design pattern. In a wall surface formed by bonding together a plurality of sheets of mounting materials 11, there is no particular restriction as to whether the directionality of the plurality of concave and / or convex stripes of adjacent mounting materials 11 is the same or different, and this can be selected depending on the desired finish of the wall surface.

[0064] Preferably, the directionality of either or both of the multiple concave and convex stripes of the pattern portion of the covering material is the same. This allows the patterns of adjacent mounting materials to be separated, and makes full use of the textured design pattern of the directional multiple concave and / or convex stripes of one mounting material, resulting in a finished wall surface, etc., with a unified texture as a whole.

[0065] Furthermore, the coating material on which the pattern portion 12 is formed is preferably filled in the joints between the adjacent facing materials 11 at intervals of 3 to 10 mm to a thickness greater than the thickness of the facing materials 11. This allows the pattern to be separated from adjacent facing materials 11, highlights the directional concave and / or convex stripes, and allows the wall surface, etc., to be finished with a unified texture while fully utilizing the textured design pattern.

[0066] If the thickness of the covering material 11 is thinner than this, the pattern of the covering material 11 may not be emphasized as much, resulting in a finished product with poor texture. This coating material may be any material capable of filling the thickness of the facing material 11 or more, and examples of such materials include coating materials, sealing materials, putties, and the like.

[0067] Among these, it is preferable to use a coating material similar to that used to form the pattern portion 12 of the covering material 11, so that the finished wall surface, etc. can have a uniform texture as a whole. Furthermore, preferably, the direction of either or both of the multiple concave and convex stripes of the pattern portion 12 of the facing material 11 is the same, and the coating material forming the pattern portion is filled in the joint portion between adjacent facing materials 11 spaced 3 to 10 mm apart to a thickness greater than the thickness of the facing material.

[0068] This filling method is not particularly limited and can be done by putting the coating material into a tube-shaped container and filling the joint area from the end of the tube, and it is also possible to fill the coating material using a trowel or spatula, etc. When the same coating material as that of the facing material 11 is used for this filling, it is possible to carry out the filling without curing the facing material 11, resulting in good work efficiency.

[0069] After filling, a pattern of multiple recesses, protrusions, or both, having the same directionality as the patterned portion 12 is formed. This allows the finished wall surface to have a sense of unity as a whole and a textured finish. As a method for forming a pattern of multiple concave and / or convex stripes having the same orientation as the pattern portion 12 after filling, the same method as that for forming the pattern portion 12 can be used.

[0070] In this method, for example, when finishing is performed using multiple sheets of covering material 11 as shown in Figure 1, the spaces between adjacent covering materials 11 are filled with coating material, and then the trowel is moved in the same direction as the pattern section 12, causing the aggregate in the coating material to roll, and the pattern is formed using the trajectory of the aggregate. When finishing is performed using multiple sheets of the covering material 11 shown in Figure 2, the spaces between adjacent covering materials 11 are filled with coating material, and then a comb trowel with a triangular comb shape is used to move the filled coating material in the same direction as the pattern section 12 to create a pattern.

[0071] In the case where a finishing process is carried out using a plurality of facing materials 11 as shown in FIG. 3, the spaces between adjacent facing materials 11 are filled with a coating material, and then a pattern is applied by a pattern roller. In this case, the pattern roller is moved in the same direction as the direction of the pattern portion 12 of the covering material 11, with the applied coating material at the center and including the surrounding pattern portion 12 of the covering material 11.

[0072] Furthermore, the process of finishing a wall surface using the facing material shown in FIG. 1 will be described in more detail. First, the covering material 11 shown in Fig. 1 is prepared. The base material 13 of this covering material 11 is made of polyester nonwoven fabric with a basis weight of 50 g / m2, which is sealed with a water-based acrylic paint to improve the strength of the base material 13 and improve the adhesion with the adhesive.

[0073] For the sealing treatment, 25 g of paint was used per square meter, and the thickness of the base material 13 was adjusted to about 100 μm, making it flexible. This base material 13 was cut to a size of 80 cm x 80 cm, and the coating material for forming the pattern portion 12 was applied to the base material 13.

[0074] This coating material was made by mixing 10% by weight of silica sand with a particle size range of 1 to 1.5 mm as aggregate into the base material, which was a single gray coating material. The base material was mainly composed of an acrylic synthetic resin emulsion.

[0075] The coating material applied to the base material 13 is leveled with a trowel, and the coating material that has been leveled to a certain degree is moved laterally toward the base material 13 with the trowel, the silica sand is rolled, and the trajectory of the silica sand movement is adjusted to form a pattern of concave stripes in a fixed direction. After the pattern portion 12 was formed on the base material portion 13 in this manner, it was left to stand for a day and allowed to dry naturally. It was then forced to dry in an electric furnace at 100°C for 1 hour. After drying, the covering material was cut to a size of 60 x 60 cm, and a square covering material 11 was obtained.

[0076] The resulting facing material 11 had a directional pattern of concave stripes with a fixed horizontal direction, and the lengths of the pattern were random, with some long and some short. Fifty sheets of this covering material 11 were created, and the average thickness was in the range of 1.5 to 2.0 mm based on the grain size of the silica sand, and the weight per square meter was in the range of 1.0 to 1.5 kg, which was almost constant and stable.

[0077] Therefore, by forming a pattern portion using a single coating material that has a directional pattern of multiple concave and / or convex stripes, the pattern is emphasized, resulting in a design with texture and volume. This facing material 11 was flexible, and when the facing material 11 was bent along a cylinder having a diameter of 60 cm, no abnormalities such as cracks or breaks were observed on the surface of the facing material 11.

[0078] As shown in FIG. 4, the back surface of this covering material 11 has adhesive sections 21 on all four sides, and the adhesive sections 21 are protected by release paper sections 22. The adhesive processed portion 21 and the release paper portion 22 were made of 2 cm wide double-sided tape, the adhesive was an acrylic rubber-based material, and the release paper portion 22 was made of paper coated with fluorine resin and silicone resin.

[0079] The exterior wall surface of the building structure was finished using a plurality of these facing materials 11. This wall surface was a concrete surface, and the necessary base treatment was carried out before the facing materials were applied. This base preparation involved applying a cement-based cross-section repair material to the concrete defects with a metal trowel, resulting in a smooth wall surface that was the target of finishing. Furthermore, a water-based primer with an acrylic synthetic resin emulsion as the main ingredient was applied to this smooth surface with a paint roller to increase the adhesive strength with the adhesive.

[0080] A sheet-like joint material was applied before attaching the facing material 11. This sheet-like joint material was the same as the base material 12, and was a polyester nonwoven fabric with a basis weight of 50 g / m2 that had been sealed with a water-based acrylic paint. The width of this sheet-like joint material was 45 mm, and the roll was cut according to the length to be applied.

[0081] The sheet-like joint material was attached after determining the position where it would be attached, taking into consideration the position where the facing material 11 would be attached. The attached state is shown in FIG. FIG. 5 shows that sheet-like joint material 32 is attached in a grid pattern to a wall surface 31, and that facing material 11 is attached using this sheet-like joint material 32 attached in a grid pattern.

[0082] The sheet-like joint material 32 and the facing material 11 were attached using a polymer cement adhesive containing cement and an acrylic synthetic resin emulsion as main components. The sheet-like joint material 32 was attached by applying this adhesive to the wall surface 31 with a painting roller. The facing material 11 had the adhesive applied to its back surface with a painting roller, and was attached to the wall surface 31.

[0083] There are no particular limitations on the method of applying this sheet-like joint material 32, but multiple pieces of sheet-like joint material 32 are applied vertically to the wall surface 31 in locations taking into consideration the size of the facing material 11, the width of the sheet-like joint material, and the spacing between adjacent facing materials. Thereafter, a plurality of sheet-like joint materials 32 are attached horizontally at similarly considered locations, and the sheet-like joint materials 32 are attached to the wall surface 31 in a lattice pattern.

[0084] Conversely, multiple sheet-like joint materials 32 are attached horizontally to the wall surface 31 at locations taking into consideration the size of the facing material 11, the width of the sheet-like joint material 32, and the spacing between adjacent facing materials. After that, multiple pieces of sheet-like joint material 32 can be attached vertically at similarly considered locations, and the sheet-like joint material 32 can be attached to the wall surface 31 in a lattice pattern. Either method is acceptable.

[0085] Preferably, the end of the facing material 11 is near the center of the sheet-like joint material 32, the center of the sheet-like joint material 32 becomes the space between adjacent facing materials 11, and this part becomes the joint. By doing so, the adhesive processed portion 21 on the back surface of the facing material 11 can be uniformly adhered to the sheet-like joint material 32, making it possible to obtain a good adhesive effect.

[0086] After the sheet-like joint material 32 is applied in this manner, the facing material 11 is applied. In this case, the facing material 11 is arranged with a gap of 5 mm between adjacent facing materials, and the sheet-like joint material 32 is exposed at a gap of 5 mm as a joint. Moreover, the covering material 11 was attached so that all of the multiple recesses of the pattern portion 12 were horizontal to the wall surface 31 and had the same orientation.

[0087] The wall surface 31 pasted and finished in this way can be separated from the pattern of the adjacent mounting material 11, highlighting the pattern of the multiple directional concave and / or convex stripes of one mounting material, and fully utilizing the textured design pattern. Furthermore, on one side of this finished wall surface 31, the joints between adjacent facing materials 11, spaced 5 mm apart, were filled with a single gray coating material with a patterned portion 12 formed therein, to a thickness greater than the thickness of the facing material 11. The cross section of this is shown in FIG.

[0088] In FIG. 6, a facing material 11 and a sheet-like joint material 32 are attached to a wall surface 31, and then a coating material 41 is filled in to a thickness equal to or greater than that of the facing material 11. In this way, the patterned portions 12 of adjacent mounting materials 11 can be separated, the horizontal concave pattern of one mounting material 11 is accentuated, and a wall surface, etc., that is finished while making full use of the textured design pattern can be given a unified textured finish as a whole.

[0089] When filling the coating material 41, the coating material 41 was placed in a 500 ml tube, the end of the tube was cut to approximately the width of the joint, and the coating material 41 was filled into the joint from the end of the tube, resulting in the state shown in Figure 6. In this filling, the same coating material as that of the facing material 11 was used, so that the filling could be carried out without curing the surface of the facing material 11, and the work efficiency was good.

[0090] Furthermore, a trowel is moved in the same direction as the pattern part 12 of the facing material 11 on a part of the wall surface that has been filled with the coating material 41 before the coating material 41 dries, and the aggregate in the coating material 41 is rolled, and a pattern is formed by utilizing the trajectory of the aggregate. This state is shown in Figure 7. By doing this, it is possible to obtain a finished wall surface with a unified texture as a whole. [Explanation of symbols]
