Description

  TECHNICAL FIELD The present invention relates to a wall surface decorative method for a building and a wet coating material used for the same, and more particularly, to a wall decorative method for a building in which a siding outer wall made of a siding material is decoratively applied by a wet method, and a wet method used for the same. Regarding the coating material.

At present, when a wall surface such as an outer wall of a building becomes dirty, a repair method using a paint such as paint or a siding material to which a siding material is attached is used. In the case of a tiled building, renovation is often performed using a special adhesive and a net without peeling the tile. In the case of a block wall or the like, the entire surface is often repainted.
As in the case described above, the conventional wall repairing method focuses on improving the durable life of a building by repairing the base of a dirty or deteriorated wall.

  2. Description of the Related Art In recent years, many buildings are found by dry construction methods represented by block walls, siding boards, PC (precast / concrete) plates, metal siding plates, and the like. This method is considered to be promoted in the future because it is an excellent labor-saving method, but on the other hand, coating using a wet coating material represented by plastering material (hereinafter sometimes referred to simply as “wet material”). The goodness of the walls has also been reviewed and is increasing gradually. This seems to be the difference between the fact that the painted wall is a handmade product and that the dry material used in the dry method is factory-produced.

  At present, painted walls are proposed by various manufacturers of putty materials and the like, and are used not only for new construction but also for renovation work. The finishing is performed by a method such as ironing, roller finishing, combing finishing (finishing streak grooves), scraping finishing (battery finishing performed in a semi-solid / medium-tight state), and the like.

The durability of the siding outer wall, etc. as a factory final finished product manufactured using recent siding materials is semi-permanent, but the outer wall surface that has been subjected to surface treatment such as paint may deteriorate over time. Since the surface becomes dirty, the surface is refreshed by washing the surface with water or a detergent solution of detergent in water, or refreshed by repainting or painting the top coat every few years (for example, Patent Document 1).
On the other hand, phenol (neomafoam (: trade name), etc.), styrene (canelite (: trade name), etc.), urethane (achilles board (: trade name), etc.), wood wool board (MK board (: trade name), etc.), Insulation plywood, slate, siding (new, old, with or without paint), FRP (unsaturated polyester resin), vinyl chloride, etc. An elastic base adjustment mortar (cationic acrylic resin) for application and a cationic acrylic emulsion developed as an aqueous sealer for on-site application to these are already commercialized and known (for example, see Non-Patent Document 2). ).

"Lambda (Cement Hollow Extrusion Molded Plate)" manufactured by Showa Denko Kenzai Co., Ltd., "Search January 10, 2003", Internet, <URL: http://www.sdk.co.jp/lambda/> "Sealex AP" manufactured by Fujikawa Building Materials Co., Ltd., "Search January 23, 2004", Internet, <URL: http://www.fujikawakenzai.co.jp/seihin/cRexAP.files//frame.htm 〉

  However, on the siding-finished siding outer wall surface or the like, the siding finish is maintained even when refreshed, and the aesthetic appearance and texture are not further improved. If you have the financial resources, you can rebuild or change the surface finish to tiled, but that would be a very expensive renovation.

  Therefore, the present inventors have conducted extensive research on a method of making the quality of a painted wall more inexpensive and simpler in the renovation of a building such as a house or an outer wall that has been siding finished. As a makeup method, a wiping method using a wet material has been found and proposed.

  After that, the present inventors conducted further confirmation tests and studies in order to develop an optimum wet material for the wall surface of the building, particularly for the siding material (outer wall surface). The basic requirements of the wet material for the siding material include, as described above, the siding outer wall surface and its adhesiveness with respect to the adhesive strength to the joints and the like (hereinafter sometimes referred to as “adhesiveness”), as well as wiping (wiping). In addition to two of the wiping properties (wiping and wiping operability) from the necessity of the step), the elasticity and the non-shrinkage of the siding are appropriate as described later. The main required performance is four).

  Conventionally used mortar-based wet materials mixed with an acrylic emulsion resin, for example, a water-based emulsion mortar, are common as joint materials used for joints such as ordinary tiles, and are inexpensive and easy to use. Things. However, when such a mortar-based material is used as a wet material, it is very easy to apply, and the wiping workability is good, but if the siding where various materials exist is the opponent, the compatibility is poor. There was a problem that the adhesiveness was not satisfied and there was a risk of peeling, which was not practical. In this case, examples of the siding material having poor compatibility include, for example, siding made of glass or metal, or siding provided with a top coat containing a material component such as Teflon (registered trademark) (Comparative Example 1 in Table 1 described later). reference).

Acrylic resin-based materials are commonly called putty materials, and when they are used as wet materials, they have high adhesiveness and resistance to cracking, but their wiping work is poor because of their poor wiping workability. (See Comparative Example 2 in Table 1 described later).
Further, when the above-mentioned cation-based elastic base adjustment mortar (cationic acrylic resin) is used as a wet material, there is a problem that workability of application and wiping is poor. This was caused by the aggregate (silica sand) contained in the cation-based elastic base adjustment mortar, and it was found that this hindered the application and wiping properties (Comparative Example in Table 1 described later). 3).
Therefore, when the confirmation test was performed by further removing the aggregate (silica sand) contained in the cation-based elastic base adjustment mortar, the wiping workability was improved, but the non-shrinkage property was not satisfied. (See Comparative Example 4 in Table 1 described later).

Therefore, the present invention has come to fruition as a repair method using a wet method and a decorative method for the purpose of improving the aesthetic appearance and texture of a building, which was not considered at all in the above-described conventional wall repair method. The first object is to increase the asset value of a building having a wall surface.
It is a second object of the present invention to provide an optimum wet coating material capable of satisfying the required performance of the wet coating material for the wall of a building.

In order to solve the above problems and achieve the above object, the invention according to the claims employs the following characteristic means and configurations.
The invention according to claim 1 is characterized in that the wall of the building is decorated with a wet coating material. (See claim 2).

According to a third aspect of the present invention, in the method of making a wall of a building according to the second aspect, the wet coating material has an appropriate adhesion and a wiping property to the wall. A coating step of applying the wet coating material to substantially the entire surface of the wall surface including at least one of the joint and the concavo-convex pattern; and after the coating step, the wet coating material is coated with the joint and the concave. A wiping step of wiping the wet coating material on the wall surface including the convex pattern so as to remain on at least one surface of the patterns.
Here, "wet coating material has appropriate adhesion and wiping properties to the wall surface" means that at least one of joints and concave patterns to achieve the effects of the present invention described below. A coating process of applying a wet coating material to substantially the entire surface of the wall surface including the wall surface including the convex pattern so that the wet coating material remains on at least one surface of the joints and the concave pattern after the coating step. It means the minimum necessary working conditions for carrying out and executing the wiping step of wiping the wet coating material on the surface.
Further, `` substantially the entire surface of the wall surface including at least one of the joints and the uneven pattern '' means that the wet coating material is applied by filling at least the joints and the concave portions of the concave pattern, Therefore, the work by a skilled person does not need to be applied to the convex pattern portion (for example, when the convex pattern portion covers a relatively large area).

  According to a fourth aspect of the present invention, in the method of making a wall of a building according to any one of the first to third aspects, the wall is a siding outer wall made of a siding material.

  According to a fifth aspect of the present invention, in the method of making a wall of a building according to any one of the first to fourth aspects, the wet coating material is a coating material such as cement, lime, or gypsum. There is a feature.

  According to a sixth aspect of the present invention, in the method of making a wall of a building according to any one of the first to fourth aspects, the wet coating material is a finish coating material such as a putty material. .

  According to a seventh aspect of the present invention, the material of the siding material according to the fourth aspect is made of a combination of at least one of a metal system, a wood system, a ceramics system, and the like.

  According to an eighth aspect of the present invention, there is provided a wet coating material used for a wall surface makeup method in a building according to any one of the first to seventh aspects, wherein the wet coating material contains a cationic material component. Features.

  According to a ninth aspect of the present invention, in the wet coating material according to the eighth aspect, the wet coating material includes an elastic resin material component that exhibits elasticity at least when dried.

  According to a tenth aspect of the present invention, in the wet coating material according to the ninth aspect, in addition to the elastic resin material component, at least a material component exhibiting non-shrinkage that falls within an appropriate degree of shrinkage when dried is included. And

  According to an eleventh aspect of the present invention, in the wet coating material according to the ninth or tenth aspect, the elastic resin material component is removed from the wet coating material to enable trial coating.

  As described above, according to the present invention, it is possible to solve the above-described problems of the related art and to provide a new method of making a wall of a building. That is, according to the wall surface makeup method of the present invention, since the wall surface in a building is made with a wet coating material, it is very easy as a construction method, and the amount of the wet coating material used can be suppressed to a relatively small level. Inexpensive, and the aesthetics and texture of buildings with wall surfaces are improved. In particular, when a siding outer wall surface made of a siding material including at least one of joints and uneven patterns is applied through a coating process and a wiping process using a wet coating material, a factory production having a relatively monotonous finish is performed. Because the siding outer wall of the product is not evenly wiped with the applied wet coating material, the aesthetic appearance and texture are improved to the extent that the handmade warmth is completely opposite to the monotonous finish. Has a remarkable effect.

  Further, according to the present invention, since the wet coating material contains a cationic material component, it is possible to determine whether the material of the outer wall surface of the building, particularly, the material of the siding material is a metal material, a wood material, a ceramic material, or the like. Can meet the required performance, and can be used for a wide range of siding materials. Therefore, both new construction and renovation can be easily performed.

  Further, according to the present invention, by including an elastic resin material component that exhibits elasticity at least when the wet coating material is dried, the movement of the outer wall surface in the building, particularly follows the movement of the siding itself and the siding, The generation of cracks and the like can be prevented.

  Further, according to the present invention, by removing the elastic resin material component from the wet coating material and enabling the test coating, it is possible to determine whether or not the pattern design desired by the user several times in a short time. However, you can have it checked by trial coating.

Hereinafter, embodiments of the present invention including the best mode for carrying out the present invention (hereinafter, referred to as “embodiments”) will be described with reference to the drawings.
The present invention relates to a wall surface makeup method for a building using wiping (wiping) which is not included in the conventional wall repair and makeup method of a building, and an embodiment of the invention (hereinafter, “embodiment”). Will be explained.
As an embodiment of the present invention, a case will be described in which the method for applying a wall face in a building according to the present invention is applied to a surface of a siding outer wall made of a siding material having a remarkable effect of the present invention, that is, a siding outer wall face. . In this example, it is assumed that the siding outer wall surface has at least one of a joint having a relatively shallow depth and a concavo-convex pattern having a relatively small step as a construction condition.

As is well known, the material of the siding outer wall may be any of metal-based, wood-based, ceramic-based, and the like, or may be a material formed by appropriately combining these. In this example, the siding outer wall surface has a concave joint and an uneven pattern is formed.
Further, as a prerequisite for wiping, the wet coating material has appropriate adhesiveness (adhesiveness) and wiping properties to a siding wall surface as an example of a wall surface in a building.
When applying a wet coating material regardless of the siding material (metal, wood, ceramic, etc.), the performance basically required as a wet coating material includes the adhesiveness (adhesion) and wiping described above. Elasticity and non-shrinkage are required in addition to the take-off.
That is, the adhesiveness (adhesiveness) is a required performance relating to the adhesive strength with the outer wall surface of the siding and its joints, and the wiping performance (wiping workability) requires a wiping (wiping) step. Required performance. Elasticity means at least the ability to follow the movement of the siding itself and the movement of the siding when dry, and is the required performance to prevent cracks and cracks, etc., and the non-shrinkage is at least a moderate range when dry. This is the required performance to be within the amount of shrinkage, that is, within an appropriate degree of shrinkage.

  Hereinafter, with reference to FIG. 1, the steps in the decorative siding outer wall surface construction method will be described. As shown in FIG. 1, this step includes a cleaning step (I) as a first step, a coating step (II) as a second step, a wiping step (III) as a third step, and a fourth step. It comprises a finishing step (IV) as a step.

  First, the washing step (I) for washing the outer wall surface of the siding to be renovated and made up is performed. In the cleaning step (I), the surface base of the siding outer wall is sufficiently cleaned by, for example, high-pressure cleaning using water, a detergent solution, or the like. This washing step (I) is not always necessary in the present invention. That is, for example, immediately after the siding outer wall is manufactured at a factory or the like, or immediately after being constructed as a building, and the surface is not dirty, the present invention is particularly preferred because the wall surface is excellent in design. This is because a specific makeup method may be applied. Therefore, the washing step (I) is not an essential step of the present invention.

Next, an application step (II) of applying and applying a wet coating material (hereinafter, referred to as “wet material”) on the outer wall surface of the siding is performed. As described above, the wet material is applied to substantially the entire siding outer wall surface including at least one of the joint and the concave pattern. At this time, the siding is thinly coated with a trowel so that the wet material can sufficiently enter the joints and concave portions of the uneven pattern on the siding outer wall surface.
Here, as the wet material, a material suitable for the material of the outer wall surface of the siding and a desired material is selected and used from materials made of a coating material such as cement, lime or gypsum.

Next, a wiping step (III) is performed after the coating step (II). That is, the wet material on the siding outer wall surface including the convex pattern is wiped so that the wet material remains on the surface of at least one of the joint and the concave pattern (both the joint and the concave pattern in this embodiment) of the siding outer wall surface. .
In the wiping step (III), tools such as squeezed rags, sponges, or brushes with short hairs (hereinafter referred to as “wiping tools”) are checked by checking the tightness (solidified state) of the wet material application section. Wiping (wiping) of the wet material at the convex portion on the outer surface of the siding. By repeating this wiping, the wet material in the convex portions of the base siding material is removed to some extent, and the wet material in the joints and the concave portions in the vicinity thereof is wiped well.

Next, as a finishing step (IV), after the applied wet material is sufficiently hardened, the surface is wiped with a clean rag or the like, or is polished in addition thereto to finish.
Further, after several days, after the applied base (wet material) is sufficiently dried, an appropriate top coat is applied to prevent contamination. The finishing step (IV) is not a necessary step in the present invention, and the wet material contains, for example, a component corresponding to the top coat, and performs a function corresponding to the top coat when sufficiently dried and cured as described later. In the case where it is fulfilled, it may be unnecessary. Therefore, the finishing step (IV) is not an essential step of the present invention.

In the example of the above-described embodiment, an example in which the present invention is applied to the siding outer wall surface is described. However, the present invention is not limited to this, and various wall surfaces (for example, indoor ceilings, Needless to say, the present invention is applicable to indoor and outdoor wall surfaces, indoor and outdoor floor surfaces, and the like. Further, the wall surface of the building is not limited to the example of the embodiment described above, and may be any wall provided with at least one of a joint having a relatively shallow depth and an uneven pattern having a relatively small step.
In order to apply to a wide range of siding materials irrespective of siding materials (metals, woods, ceramics, etc.), it is important that the wet material contains a cationic material component. In the conventional anion-based wet material, when applied to concrete or mortar, the required performance was almost satisfied as described in the problem section to be solved by the present invention. Alternatively, for example, when a top coat containing a Teflon (registered trademark) component is applied to an outer wall surface of a siding made of metal, wood, ceramic, or the like, a sufficient adhesive strength cannot be obtained, and eventually, peeling is performed. Is not practical.

  In addition, in order for the wet material to satisfy the above four required performances, it is necessary that the wet material includes at least an elastic resin material component exhibiting elasticity when dried, and at least other than the elastic resin material component. It is also necessary to include a material component exhibiting non-shrinkage that falls within an appropriate degree of shrinkage when dried.

  The use of a wet material obtained by removing the elastic resin material component from the elastic resin material having elasticity and non-shrinkability (hereinafter referred to as “test coating wet material”) enables trial coating, and color patterns and patterns on the wall surface. The user can confirm the design confirmation many times in a simple process in a short time, and the user can finally determine a desired design. FIG. 12 shows an outline of a process of applying a makeup to, for example, an outer wall surface of a siding using the test coating wet material.

  As shown in FIG. 12, from the cleaning step (I), which is not an essential step, the coating step (II) of applying and applying a test wet material to the outer wall surface of the siding is performed in the same manner as described above. After performing the wiping step (III), check whether the pattern and design are desired by the user, take a color photo or color video if necessary, and mix the components of the test coating wet-type material Although there is some time width, for example, if it is within 3 hours as in Example 4 described later, the test coating wet material can be easily dropped by the water washing step (IV) of washing with water.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Throughout the embodiments and the like, components (members and components) having the same function, shape, and the like will be described once and will not be further described by assigning the same reference numerals. For the sake of simplicity of the drawings and the description, even if they are components that should be shown in the drawings, components that do not need to be specifically described in the drawings may be appropriately omitted without omission. The thickness of each layer in the cross-sectional view is exaggerated and enlarged.

The first embodiment will be described with reference to FIGS.
In the first embodiment, as shown in FIGS. 2 and 3, each step of the makeup method in the case where the siding outer wall 2 of the siding outer wall 1 of the tile-like or pseudo-stone style is applied with a wet material will be described.

The siding outer wall surface 2 shown in FIGS. 2 and 3 has a large brick pattern of a sandstone texture, that is, a textured surface of a brick and a relatively shallow linear joint 3 having a maximum depth of 2-3 mm. In addition to being provided with a relatively uneven surface pattern, it is finished in a smart design that moderately suppresses the uneven pattern. In FIGS. 2 and 3, reference numeral 4 denotes a concave portion of the uneven pattern on the siding outer wall surface 2, and reference numeral 5 denotes a convex portion of the uneven pattern.
As a material for the siding outer wall 1, for example, a metal-based steel plate or an aluminum plate which has been subjected to an appropriate surface treatment is used.

First, as a cleaning step (I), the siding outer wall surface 2 to be repaired / make-up is sufficiently and cleanly cleaned by high-pressure cleaning using a detergent solution or water.
Next, as an application step (II), an existing cement-based tile joint material 6 (color: white) as a wet material is applied to the entire surface of the siding outer wall surface 2 as a coating tool, for example, a rubber iron (hereinafter referred to as “rubber iron”). Apply with. In FIG. 3, the cement-based tile joint material 6 (hereinafter, simply referred to as “joint material 6”) is shown by a cross-section in a satin pattern. Since the depth of the joint 3 is 2 to 3 mm at the maximum as described above, the joint material 6 is filled in the recess 4 by applying the joint material 6 by ironing, and especially the joint 3 is sufficiently jointed. The material 6 is packed and the portion of the convex portion 5 is applied so as to be very thin.

Next, a wiping step (III) is performed. That is, one to two hours after the completion of the application of the joint material 6, the surface of the siding outer wall surface 2 to which the joint material 6 has been applied is checked using, for example, a sponge as a wiping tool while checking the tightness of the joint material 6. After wiping, the material (joint material 6) of the joint 3 and the concave portion 4 on the surface is lightly wiped so as not to be wiped off.
Further, after 1-2 hours from the wiping of the joint material 6, after confirming that the material (joint material 6) remaining in the concave portion 4 is sufficiently hardened, the surface is repeatedly wiped with a sponge. Then, extra material (joint material 6) on the siding outer wall surface 2 is dropped cleanly.

  Next, as the finishing step (IV), after several days have passed and the material (joint material 6) has been sufficiently dried, the joint 3 and the concave portion 4 include the siding outer wall surface 2 coated with the joint material 6. A top coat 7 made of an appropriate material is applied to the entire surface of the siding outer wall surface 2 to prevent contamination.

FIG. 4 shows a state of the siding outer wall surface 2 after makeup in each of the above-described steps. In FIG. 4, white portions remaining in the joints 3 and the concave portions 4 on the surface are shown in white. (Joint material 6).
Compared to the state before makeup on the siding outer wall surface 2 shown in FIG. 2, the state after makeup on the siding outer wall surface 2 shown in FIG. 4 seems to have individual differences in terms of preference, Aesthetically, the siding outer wall surface 2 having a relatively monotonous finish, which is a factory-produced product, has a white material (joint material 6) penetrating into the joints 3 and the concave portions 5 on the surface, and the wiping is not uniform. The handmade warmth is completely opposite to the monotonous finish. In addition, the texture of the siding outer wall surface 2 after the makeup is clearly different, and the siding material, which is a conventional dry material, looks warm like a handmade wet material finish, and the durability of the siding outer wall surface 2 is high. Rather improve without decreasing. Eventually, the asset value of the building having the wall surface will increase.

Second Embodiment A second embodiment will be described with reference to FIGS.
The second embodiment has a siding outer wall 11 having a siding outer wall surface 12 in place of the siding outer wall 1 having the siding outer wall surface 2 to be subjected to makeup in the first embodiment as compared with the first embodiment. The main difference is that an existing putty-like finish coating material 16 as a wet material is used instead of the joint material 6 of Example 1. The second embodiment will be described below focusing on the differences.

  As shown in FIGS. 5 and 6, the siding outer wall surface 12 is a large brick pattern having a sandstone texture similar to that of the first embodiment, and has a relatively shallow depth of a maximum of 1 to 2 mm. In addition to the linear joints 13, the concave and convex portions 4 and the convex portions 5 are provided as a concavo-convex pattern having relatively few steps, as in the first embodiment. The material of the siding outer wall 11 is the same as in the first embodiment.

Each step of the makeup method for the siding outer wall surface 12 will be described.
First, as a cleaning step (I), the siding outer wall surface 12 to be repaired / make-up is sufficiently and cleanly cleaned by high-pressure cleaning using a detergent solution or water.
Next, as an application step (II), a putty-like finish coating material 16 (color: white) is applied to the entire surface of the siding outer wall surface 12 using, for example, a rubber iron as an application tool. In FIG. 6, the putty-like finish coating material 16 is shown by a cross section of a satin pattern. Since the depth of the joint 13 is at most 1 to 2 mm as described above, the putty-like finish coating material 16 is packed in the recess 4 by ironing with the putty-like finish coating material 16, and the joint 13 particularly The part is sufficiently filled with the putty-like finish coating material 16 and the part of the convex portion 5 is applied so as to be very thin.

Next, a wiping step (III) is performed. The existing putty-like finish coating material 16 has a very high adhesion to the base material (siding outer wall surface 12) when dried, so immediately after the application, the putty-like finish coating material 16 is used, for example, using a sponge as a wiping tool. The surface of the siding outer wall surface 12 coated with 16 is wiped, and the material of the joints 13 and the concave portions 4 on the surface (the putty-like finish coating material 16) is wiped clean so as not to be wiped off. The uncoated material (putty-like finish coating material 16) is removed as soon as possible.
The existing putty-like finish coating material 16 has severe skinning on the surface, and although the applied content is still soft, only the surface is easily skinned, so that wiping timing and finishing are difficult.
Next, as a finishing step (IV), several hours after the wiping of the putty-like finish coating material 16 is completed, the joint 13 and the recess 4 include the siding outer wall surface 12 including the putty-like finish paint material 16 applied thereto. A top coat 17 made of an appropriate material is applied to the entire surface of the wall surface 12 to prevent contamination.

FIG. 7 shows a state of the siding outer wall surface 12 after the dressing by the above-described process. In FIG. 7, white portions (white materials remaining in the joints 13 and the concave portions 4 on the surface) are shown in white. This shows a putty-like finish coating material 16), which has the same aesthetic appearance and texture as described in the first embodiment, and also improves the durability of the siding outer wall surface 12 without decreasing it. Eventually, the asset value of the building having the wall surface will increase.
As described in the embodiment, in Examples 1 and 2, the cleaning step (I) and the finishing step (IV) can be omitted.

  As can be seen from Examples 1 and 2, the construction method can be very easily carried out, and the wet material is basically finished by wiping and then wiping. It can be understood that the method is very easy (dry method for the convex portion and wet method for the concave portion). From the above-mentioned contents, the decorative method of the wall surface in the building according to the present invention and the wet coating material used for the same are not limited to the siding outer wall surface, but the wall surface in general buildings (for example, indoor ceiling, indoor and outdoor wall surfaces). , Including indoor and outdoor floors).

Third Embodiment A third embodiment will be described with reference to FIGS. 8 to 12 and Table 1.
Example 3 is different from Examples 1 and 2 in that the joint material 6 of Example 1 and the putty-like finish coating material 16 of Example 2 (both wet materials) are used instead of siding materials (metal-based, wood-based). The main difference lies in the use of a cationic elastic substrate adjustment material containing a cationic material component that can be applied to a wide range of siding materials regardless of whether the material is a ceramic material or a ceramic material.
Hereinafter, Example 3 will be described with a focus on the differences. First, in order to compare the content of the material components of Example 3 and the characteristics thereof, a part was also described in the problem section to be solved by the invention. Comparative examples 3 and 4 will be described.

(Comparative Example 3)
The wet material according to Comparative Example 3 is mainly composed of the above-mentioned cation-based elastic base adjustment mortar (cationic acrylic resin) as the above-mentioned cation-based elastic base adjustment material, and is applied to the siding outer wall surface. When used as, there was a problem that workability of application and wiping was poor. This was attributed to the aggregate (silica sand) contained in the cation-based elastic substrate adjusting mortar, which was found to hinder the application and wiping properties.

  The cation-based elastic base adjustment mortar (cationic acrylic resin) was developed by Fujikawa Building Materials Co., Ltd. FIG. 8 shows the outline of the test specimen used for the adhesion (adhesion) test, and FIG. 9 shows the adhesion (adhesion). FIG. 10 shows the test results of the adhesion (adhesion) strength of the test method.

  As shown in FIG. 8, two siding boards 21 having a size of 300 × 300 mm were bonded using a caulking material 28. At this time, the bottom surface of each siding board 21 was fixed with a plywood 27 using epoxy resin so that each siding board 21 did not move in the in-plane and out-of-plane directions. After the application of the caulking material 28, it was confirmed that the caulking material 28 was sufficiently cured, and then a cation-based elastic substrate adjusting mortar was applied. The number N of test pieces was set to 3, and as a curing period, air curing was performed for 7 days after the application of the caulking material 28. After curing, 12 g of a three-fold diluted solution of Sealex AP (trade name: cationic acrylic emulsion manufactured by Fujikawa Building Materials Co., Ltd.) was applied as a primer (a permeable base reinforcing material, also known as sealer) and dried sufficiently. Then, 12 g of the second application was applied. After the primer was applied, it was confirmed that the primer was sufficiently dried, and then an elastic finish was applied thereon to obtain a test specimen. After finishing, an adhesion (adhesion) test was performed with a curing period of 7 days and the number of test pieces N = 5.

The specifications of the siding board 21 for the test were a cement-based (ceramic-based) siding board having a fluororesin (polytetrafluoroethylene) -based coating as a final finish (top coat). In FIG. 8, reference numeral 29 denotes a joint formed at a joint.
As shown in FIG. 9, before the adhesion (adhesion) test, a 40 × 40 mm steel attachment 30 shown by cross hatching is attached and fixed to the application surface of the elastic finish material described with reference to FIG. 8 by epoxy resin. Then, a cut was made in the periphery with a cutter, and an out-of-plane adhesion test was performed. The tester measured the adhesive strength at a crosshead speed of 1.0 mm / min using an autograph manufactured by Shimadzu Corporation. 8 and 9, reference numeral 26a denotes a portion of the cation-based elastic base adjustment mortar and the elastic finish material where the coating thickness is large, and reference numeral 26b denotes a cation-based elastic base adjustment mortar and the elastic finish material. Each of the completely coated surfaces with a small coating thickness is shown.

  From the test results of the adhesion strength shown in FIG. 10, it can be seen that the adhesion strength of the completely coated surface 26b on which the cation-based elastic base adjustment mortar and the elastic finish are applied relatively thinly tends to be low. This is because the elastic finish is immersed in water and slicked and wiped off, so that there is much slag at the thin complete application surface 26b and the strength is reduced. FIG. 10 summarizes the results of performance tests performed on the above-mentioned elastic finishing materials based on JIS A 6909 (finish coating material for building).

The cation-based elastic base adjustment mortar is a blend of ultra-high-molecular-weight polyethylene short fiber as a material component exhibiting high strength and non-shrinkage property than carbon / aramid fiber and silica sand of No. 4 or No. 5. is there. By mixing ultra-high-molecular polyethylene short fibers (short fiber length 12 mm), joint cracks are prevented and super elastic re-emulsifying powder acrylic cation resin has strong adhesion (adhesion) and flexibility, so siding It acts as a cushioning material to the elastic finishing material following the deformation of the siding and the movement of the siding. Incidentally, the performance of the cation-based elastic base adjustment mortar is as follows: bending strength is 22.5 kgf / cm ² , stroke to break is 4.0 mm, compressive strength is 40 kg / cm ² , water absorption is 0.28 g, standard The curing adhesion was 10 kgf / cm ² , the low temperature curing adhesion was 10 kgf / cm ² , and the standard adhesion of FRP (unsaturated polyester resin) was 5.8 kgf / cm ² .

  However, in the evaluation results of Comparative Example 3, as shown in Table 1, the wiping property was at an unusable level, and the application / wiping workability was poor. This is because the original material of the cation-based elastic base adjustment mortar blended in Comparative Example 3 uses silica sand of relatively coarse particles of Nos. 4 to 5 (the smaller the number, the larger the particle diameter). Therefore, it was found that the workability of applying and wiping, such as applying a thin film or wiping, was poor.

(Comparative Example 4)
In Comparative Example 4, since the application and wiping workability of Comparative Example 3 was poor and it was at an unusable level, silica sand as an aggregate was removed from Comparative Example 3 to improve the application and wiping workability, and the ultra-high performance was obtained. The same test and evaluation as described above were conducted by blending and adjusting the composition from Comparative Example 4 in which the molecular polyethylene short fibers were also removed. As a result, the amount of shrinkage was increased due to the loss of the aggregate, and cracks were generated. As shown in Table 1, the non-shrinkage reached an unusable level.

  Therefore, in Example 3, as compared with Comparative Example 4, a small amount of silica sand of No. 5 or 6 finer than Comparative Example 3 and a fine aggregate of No. 7 or 8 were added, resulting in a wiping property. And the non-shrinkage property were at the level of good use and at the level of use, and the composition was well balanced between the application / wiping workability and the anti-shrinkage force. However, it did not reach a level at which no cracking occurred.

In Example 4, compared with Example 3, the ultrahigh molecular weight polyethylene short fiber blended in Comparative Example 3 was mixed. This compounding amount was smaller than the compounding amount in Comparative Example 3 in order to avoid inferior coating and wiping workability as compared with Comparative Example 3, and was added while maintaining a balance that no cracks were generated. As shown in Table 1, an ideal wet-type material containing a cation-based material component having a good use level in all of the four required performances was obtained by the above-described blending method.
Using the wet material of Example 4, for example, the siding outer wall surface 2 (for example, a metal steel plate or an aluminum plate coated with a fluororesin (polytetrafluoroethylene) -based coating) shown in FIGS. 2 and 3 A specific example of applying makeup will be described with reference to FIGS.

  2 and 3, first of all, as a cleaning step (I) or a base adjustment, which is not an essential step, the unevenness of the outer wall surface 2 of the siding to be renovated / make up (adjustment of siding floating and unevenness by carpentry work). At the same time, debris, dust, grease, and the like on the ground surface of the siding outer wall surface 2 are sufficiently and thoroughly washed using, for example, a detergent solution or water to obtain a dry and clean surface.

  Before proceeding to the coating step (II), if the peripheral portion including the siding outer wall surface 2 is severely degraded and water-absorbed, a primer coating treatment may be performed. As a primer, when "SIREX AP" (trade name) manufactured by Fujikawa Kensetsu Kogyo Co., Ltd., which is a kind of cationic acrylic emulsion, is applied, it works particularly effectively in order to secure adhesion. As a mixing example, a mixture of 16 kg of water and 16 kg of water relative to 16 kg of Sealex AP (main agent), that is, a mixture of 1: 1 main agent and water was used. This primer coating process is not an essential step and is unnecessary when the periphery of the siding outer wall surface 2 is in a dry and clean state.

Next, the wet material of Example 4 used in the coating step (II) is prepared.
Examples of the composition of the wet material of Example 4 (hereinafter sometimes referred to as “siding design mortar”) include a one-powder material A containing a cationic component and an aggregate (sand, cement), and a cationic elastic resin. A main material B containing a superelastic re-emulsifying powder acrylic cation resin as a material is prepared. As a composition example of 1 powder type material A, powder: 20 kg, fresh water: 3.5-4.0 L, and as a composition example of main material B, powder: 20 kg, admixture: 3.4 kg (above elasticity) Base adjustment mortar), Shimizu: 2.0 to 2.5 L. One powder material A has four standard colors, and a liquid pigment is blended as a custom color.

  In a clean container of stainless steel or plastic, add 90% of standard water (about 3.5L) water, add 1 powder material A and main material B, knead well with a stirrer, and gradually add the remaining water Knead until ready to work.

  Next, as a coating process (II), the kneaded siding design mortar (wet material of Example 4) is applied to the entire surface of the siding outer wall surface 2 including the joints 3 using, for example, a rubber iron as a coating tool. Since the depth of the joint 3 is a maximum of 2 to 3 mm as described above, the siding design mortar is filled with iron by siding design mortar and the siding design mortar is sufficiently filled particularly in the joint 3 part. The design mortar is packed, and the portion of the convex portion 5 is applied so as to be very thin.

  Next, a wiping step (III) is performed. That is, the siding design mortar is cured until the surface layer becomes semi-dry after the application of the siding design mortar (curing conditions: temperature: 20 ° C., about 10 to 20 minutes). After this curing, while observing the tightness of the siding design mortar, using, for example, canelite (trade name: a kind of foam insulation or abrasive) as a wiping tool, the siding outer wall 2 coated with the siding design mortar is used. Grind until the surface is visible.

  The appearance (design pattern) of the siding outer wall surface 2 that has been seen is confirmed, and if necessary, the material of the joints 3 and the concave portions 4 on the surface is partially or entirely wiped off so that the material of the joints 3 and the concave portions 4 on the surface is not wiped off. ) Wipe gently with). When using the above-mentioned cannelite, the rough and siding design mortar is cut out when rubbing lightly, and when rubbing strongly, it will be cut off itself, so wiping workability compared to using a normal cloth type wiping tool Was very good.

  Then, as a finishing step (IV), after several days have passed and the wet material (siding design mortar) of Example 4 has been sufficiently dried, the siding design mortar is applied to the joints 3 and the recesses 4 thereof. A top coat 7 made of an appropriate material is applied to the entire surface of the siding outer wall surface 2 including the outer wall surface 2 to prevent dirt (not an essential step).

In Example 5, a superelastic re-emulsifying powder acrylic cation resin (mixing resin in a mixture) as a cationic elastic resin material component was removed from the wet material of Example 4 used in the coating step (II). If not used, the time for solidification can be extended, so that trial coating for the pattern design, etc., of the siding outer wall surfaces 2 and 12 can be performed. For example, the siding design mortar (but not containing the admixture resin) can be easily dropped by washing with water shown in FIG. 12, and the trial coating can be performed as many times as desired until a desired pattern design is obtained. This is in contrast to the case where a general paint / paint is used for confirmation, in which it takes time to remove the paint / paint and it takes a lot of work.
As described above, the present invention has been described with respect to specific embodiments and examples. However, the present invention is not limited to the above-described embodiments and examples, and may be configured by appropriately combining these. It will be apparent to those skilled in the art that various embodiments and examples can be configured within the scope of the present invention according to the necessity and use thereof.
