Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall construction method for constructing a three-dimensional, high-quality painted wall on the surfaces of the inner and outer walls of a building.

[0002]

2. Description of the Related Art Generally, for wall surfaces that are required to have a high-class feeling and artistry, there is a tendency to prefer wall coverings that make use of the solid texture of natural stone such as granite, marble and sandstone. However, wall coverings made of genuine natural stone are expensive, and there are significant restrictions on construction such as wall shape and joint division. Therefore, conventionally, a so-called stone material finish coating material has been applied to the wall surface to perform a wall construction method for obtaining a texture resembling a natural stone material.

As a finish coating material used in such a wall construction method, a ceramic coating material obtained by mixing synthetic resin emulsion with natural stone or ceramic aggregate is typical. It is possible to obtain deep colors and textures similar to those of various natural stone materials by changing the color and particle size of each type of aggregate to be mixed in two or three types.

The ceramic coating material is usually applied by using a spray gun, a roller, a trowel or the like after applying a cement-based base adjustment coating material to a base material which has been pretreated with a primer or the like. The surface of the applied ceramic coating material is subjected to a sander finish if necessary, and then a clear coat coating material is applied.

[0005]

In the above-mentioned conventional wall coverings made of a stone finish coating material, the surface is often finished to have a fine stone-like uneven surface, but depending on the design intention, it may be a split skin-like irregular surface. There is also a case where a rough pattern is formed, or an artificial three-dimensional pattern is added by brushing, combing, roller pressing, or the like. However, simply forming various undulations and patterns on the surface of the stone finish coating material tended to make the texture monotonous, and it was not possible to express a sufficient sense of luxury and profoundness. Further, in the case of forming a mural-like or craft-like three-dimensional pattern, it has been sometimes desired to finish by emphasizing the change in color tone and the shadow.

Therefore, the present invention has a deeper texture and color feeling than the conventional wall covering made of stone finish coating material,
Another object of the present invention is to provide a wall lining method that is extremely excellent in designability and that can freely express shadows and changes in color tone according to the surface undulations and patterns.

[0007]

In order to solve the above-mentioned problems, in the wall lining method of the present invention, a cement-based base conditioning coating material is thickly applied to the surface of a base wall material that has been cured and pretreated, and An undercoating step of forming a design undulation on the surface before the adjustment coating material is cured, and after the base adjustment coating material is cured, a synthetic resin emulsion is mixed with a colored aggregate made of natural stone or porcelain And an intermediate coating step of coating the first ceramic coating material on the entire surface of the base adjustment coating material.

In the present invention, in the undercoating step of thickening the base adjustment coating material, a design relief which determines the impression of the coated surface is formed over the entire coated surface. At this stage, it is possible to freely give a three-dimensional expression of a wide variety of patterns, from natural stone to murals and crafts.
In forming the undulations, various tools such as a trowel, a brush, a bamboo broom, a rake, or a pressing plate can be used depending on the intention of patterning. Then, in the intermediate coating step of applying the first ceramic coating material, a solid stone-like texture or color is applied to the entire coated surface. Since this intermediate coating process does not require the thickness as much as the undercoating process, a method with good workability such as spraying with a spray gun can be selected.

According to the present invention, since the undulations are formed on the surface of the undercoating coating material which is relatively cheaper than the ceramic coating material and suitable for thickening, workability is better than that when thickening the ceramic coating material. , It is possible to give a wide variety of economical design expressions.

As the undercoat adjusting coating material, a cement-based elastic cation obtained by mixing Portland cement and an inorganic aggregate in a hardening liquid composed of a cationic acrylic synthetic resin emulsion is particularly preferable. It is excellent in strength and resistance to cracking.

Further, in the wall covering method of the present invention, following the above-mentioned intermediate coating step, a second ceramic coating material having a color tone different from that of the first ceramic coating material, or a silicon resin type, urethane resin type, acrylic resin And a fluororesin-based colored coating material is partially coated on the surface of the first ceramic coating material. By this overcoating step, the texture and color tone can be further deepened, and the shade of the undulations and the change in color tone can be emphasized, and an extremely three-dimensional finish can be obtained.

Further, in the wall covering method of the present invention, following the above-mentioned intermediate coating step or top coating step, a metal powder coloring resin coating material having a color tone different from that of the coating material used in each of the above-mentioned steps is applied in the intermediate coating step or It is characterized in that it is provided with a change coating step of partially coating the coating surface by the top coating step. By this changing coating step, a metallic luster feeling is partially imparted to the painted surface, and a more luxurious finish can be obtained.

Further, in the wall coating method of the present invention, following the above-mentioned intermediate coating step, top coating step or change coating step, a silicone resin-based, urethane resin-based, acrylic resin-based or fluororesin-based clear coating is applied to the entire coating surface. It is characterized by comprising an upper treatment step of applying a coating material. This allows
The weather resistance and stain resistance of the painted surface can be improved.

According to another aspect of the wall construction method of the present invention, a synthetic resin emulsion is mixed with a colored aggregate made of natural stone or ceramics on the surface of a base wall material that has been cured and prepared. The step of applying the ceramic coating material of No. 3 thickly, and forming the design undulations on the surface before the third ceramic coating material is cured; and the third ceramic coating material is cured. Then, a fourth ceramic coating material having a color tone different from that of the third ceramic coating material or a colored coating material of silicon resin type, urethane resin type, acrylic resin type or fluororesin type is applied to the third ceramic coating material. And a top coating step of partially coating the surface thereof.

That is, this wall coating method is a combination of the undercoating step and the intermediate coating step of the wall coating method according to the above-mentioned structure in one step (bottom / intermediate coating step). By using a ceramic coating material (third ceramic coating material) suitable for thickening, it is possible to perform the base adjustment, the formation of three-dimensional undulations, and the imparting of a stone-like texture in the same step. As a result, the process can be shortened, and the man-hour and the construction cost can be reduced. Also in this invention, the fourth ceramic coating material having a different color tone, or the silicon resin-based, urethane resin-based, acrylic resin-based, or fluororesin-based colored coating material is partially overcoated to improve texture and color tone. By further deepening and emphasizing changes in shades and color tones, it is possible to obtain an extremely three-dimensional finish.

Also, a metallic luster can be imparted to the coated surface by the change coating step of partially coating the metal powder colored resin coating material. Further, the weathering resistance and stain resistance of the coated surface can be improved by an overtreatment step of applying the clear coat coating material on the entire coated surface.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in the order of steps with reference to the drawings.

<Curing of Substrate and Sub-Treatment> The wall lining method of the present invention is applied to almost all of the base wall materials constituting a general inner wall and outer wall regardless of whether they are newly constructed walls or renovated walls. be able to. Mortar finish, concrete, AL
It is particularly suitable for C panel, PC panel, slate board, GRC board, extrusion molded cement board, plaster board, wood plywood and the like. In the pretreatment of these base wall materials, after masking parts other than the coated surface in advance, a primer whose main component is a synthetic resin emulsion is applied to the coated surface by spraying or a roller. The primer may be general water-soluble or oil-based (organic solvent type), and is appropriately selected according to the type of base wall material and the coating site.

When the base is an iron plate surface, it is rust-proofed with an epoxy resin-based rust preventive or the like, and then a base-conditioning material such as a cement-based elastic cation is sprayed thinly in two portions to roughen the surface. It is good to leave it on the surface. Further, even when repairing an old tile surface, it is not necessary to remove the tile, and the surface conditioner is sprayed as it is to leave the surface rough.

When a joint is provided, as shown in FIG.
After marking out joints on the surface of the base wall material 1, the joint bottom 2 is painted along the joint ink. For painting the joint bottom 2,
For example, a joint colorant obtained by mixing a calcareous pigment or a calcareous aggregate into a synthetic resin emulsion is used. As the joint colorant, a relatively dark color is excellent in appearance after finishing. In this wall construction method, new joints can be freely provided regardless of old tile joints, for example, even when an old tile wall is repaired.

A joint bar 3 is attached to the painted joint bottom 2. The joint bar 3 is of a multi-layer type in which, for example, the back surface of a foam polyethylene core material 31 is an adhesive surface, and a release paper 32 is attached to this back surface, and a release paper 33 is laminated on the surface of the core material 31. Is preferred.

<Undercoating step> In the undercoating step, as shown in FIG. 2, the cement-based undercoat adjusting coating material 4 is applied to the entire surface of the undercoating wall material 1 with a slightly thicker thickness (about 1 mm to 15 mm). . This application may be performed by spraying with a spray gun or applying with a roller or a trowel. As the base adjustment coating material 4, a cement-based elastic cation obtained by mixing Portland cement and an inorganic aggregate in a hardening liquid composed of a cationic acrylic synthetic resin emulsion is particularly preferable. Since this elastic cation has excellent adhesiveness to the base and also has high followability to the displacement of the base, it has characteristics that it is suitable for thickening and is unlikely to cause cracks even after construction. FIG. 5 shows the composition of "Cerafiller elastic cation" manufactured by Yamamoto Kikai Kako Co., Ltd. as a concrete example of the cement-based elastic cation.

However, it is also possible to use a less expensive non-elastic cement-based thickening base adjustment coating material for a newly constructed wall having a good surface condition of the base or an indoor wall surface having a small area.

In the undercoating step, a design undulation is formed on the surface of the undercoat adjusting coating material 4 until it is cured. Although depending on the thickness and the season, when a cement-based elastic cation is used for the base adjustment coating material 4, the time required for drying and curing is about 30 minutes to 1 hour. Cement-based elastic cations are convenient because they have good malleability and can easily form undulations, and the curing time is neither too short nor too long.

The undulating design means a large and small unevenness imitating the texture of natural stone or a stucco pattern, or a concrete three-dimensional pattern such as a mural or a craft. The work of forming the undulations is an artificial work, but depending on the design intention, the roller, trowel,
By using various tools such as a rake, a brush, a bamboo broom, and an embossing board, it is possible to freely create various patterns of undulations. However, the color of the coated surface at this stage is the monotonous gray color of the ground control coating material itself.

If the base adjusting coating material 4 is completely cured while covering the joint rod 3, the peripheral portion of the joint may be peeled off when the joint rod 3 is removed. Therefore, it is preferable to first peel off only the release paper 33 on the surface layer of the joint bar 3 to expose the core material 31 at the stage of forming the designed undulations on the surface.

<Intermediate Coating Step> In the intermediate coating step, as shown in FIG. 3, the first ceramic coating material 5 is applied to the entire surface of the hardened base adjustment coating material 4. The first ceramic coating material 5 used here is preferably a mixture of a synthetic resin emulsion and a plurality of types of colored aggregates made of natural stone or ceramics. By this intermediate coating step, the color and texture peculiar to the aggregate are given to the entire coated surface. Aggregates made of natural stone or porcelain exhibit a heavy stone-like texture and hardly fade or discolor, and are suitable for high-grade wall coverings. In FIG. 6, as a specific example of the first ceramic coating material 5,
The composition of "Ceracast S" manufactured by Yamamoto Ceramics Co., Ltd. is shown below.

The application of the first ceramic coating material 5 may be either spraying with a spray gun or coating with a roller or a trowel. However, it is sufficient that the first ceramic coating material 5 has a substantially uniform thickness over the entire coating surface. Does not need As a result, the undulations formed on the surface of the base adjustment coating material 4 will appear beautifully on the surface of the first ceramic coating material 5.

<Overcoating Step> In the overcoating step, as shown in FIG. 4, the second ceramic coating material 6 is applied to the surface of the first ceramic coating material 5.

The second ceramic coating material 6 is similar to the first ceramic coating material 5 in basic composition, but the first ceramic coating material 5 is different due to the difference in aggregate and the addition of pigment. The color tone and texture are different from. In Figure 7,
As a specific example of the second ceramic coating material 6, the composition of “Terax 100” manufactured by Yamamoto Ceramics Co., Ltd. is shown.

By partially thinly applying the second ceramic coating material 6 to the surface of the first ceramic coating material 5 using a brush or a brush, a complicated and delicate color tone change is given to the coated surface. be able to. For example, when the second ceramic coating material 6 having a darker color tone than the first ceramic coating material 5 is applied to the shadow side portion of the undulations, the shadow of the undulations is emphasized, and a very three-dimensional finish can be obtained. Also,
For example, even when stone-like monotonous unevenness is formed over the entire surface of the first ceramic coating material 5, by applying an irregular pattern of the second ceramic coating material 6 having a different color tone, The texture is much deeper than the stone finish.

In this overcoating step, the above-mentioned second
In place of the ceramic coating material 6 of the above, a colored coating material (not shown) of silicon resin type, urethane resin type, acrylic resin type or fluororesin type may be used. These coating materials are excellent in weather resistance and chemical resistance, have an extremely rich color tone, and have good workability. By imparting a partial color tone change or a shadow with these coating materials, it is possible to achieve a design expression different from the second ceramic coating material 6. Although these coating materials include water-based coating materials and organic solvent-based coating materials, it is preferable to use water-based coating materials when it is necessary to consider the effects on the human body due to solvent volatilization and environmental pollution.

As described above, in the top-coating step, a coating material having a different color tone is applied not on the entire surface to be coated, but a novel design effect which has not been obtained can be imparted. The coating material to be used can be selected from various coating materials according to the design intention. Further, this overcoating step may be performed over two or more layers by changing the color tone and type of the coating material.

<Variable Coating Step> If a finish with a glossy feeling is desired from the design intent, a variable coating step is added. In this change coating step, for example, a metal powder coloring resin coating material in which various metal powders are dispersed in acrylic resin is partially applied with a brush or a brush. In the case of mural-like or craft-like wall covering, by adding a metallic luster in this changing coating process, a more luxurious and high-class impression can be emphasized.

<Overtreatment Step> The overtreatment step is a step for forming a protective layer on the coated surface at the end of the above-mentioned steps. In this step, a silicone resin-based, urethane resin-based, acrylic resin-based, or fluororesin-based clear coat coating material is applied over the entire coated surface. The clear coat coating material also includes an aqueous type and an organic solvent type and is not particularly limited in the present invention, but an appropriate one is selected according to the composition of the lower layer coating material and environmental conditions. The clear coat coating material may be applied by spraying with a spray gun or by a roller. By this top treatment step, the weather resistance and stain resistance of the coated surface are improved. However, if the wall surface is not easily contaminated, such as indoors, the above treatment step can be omitted.

After forming the final protective layer in this way, the core material 31 of the joint bar 3 is removed to expose the joint bottom 2, and the curing is removed to complete the process.

<Other Embodiments of the Present Invention> In the wall covering construction method described above, the undercoating step of thickening the base adjustment coating material 4 to form the undulations on the surface, and the first ceramic coating material 5 on the entire surface. The intermediate coating step of applying a stone-like texture by applying it is performed stepwise, but by using a ceramic coating material suitable for thickening (third ceramic coating material)
It is also possible to combine the processes into one process (bottom / intermediate coating process).

The ceramic coating material suitable for thickening contains a large amount of aggregate which is lighter and bulkier than the first ceramic coating material 5, and is prepared by adjusting the composition of the synthetic resin emulsion or thickening material and adhering it. It is a coating material that is mixed to improve cracking and peeling and to prevent cracking and peeling. The first ceramic coating material 5 is rather suitable for spraying (thinning), whereas the ceramic coating material suitable for thickening is rather suitable for ironing. However, it is also possible to spray the latter thickly with a stucco gun or the like.

Specific examples of the ceramic coating material suitable for thickening include "Kotefine (New Cotefine) series" manufactured by Yamamoto Ceramic Industry Co., Ltd., "Sandstone" manufactured by Kikusui Chemical Co., Ltd., SK Kaken Co., Ltd. There are products such as "Elegance Stone Sagan". FIG. 8 shows the composition of “COTEFINE P” manufactured by Yamamoto Ceramics Co., Ltd.

The ceramic coating material suitable for thickening has a stone-like color and texture by itself. Therefore, by using it, it is possible to adjust the groundwork, form three-dimensional undulations, and impart a stone-like texture. Can be performed in the process of. As a result, the process can be shortened, and the man-hour and the construction cost can be reduced.

Even when such an under / intermediate coating step is performed, the subsequent steps (top coating step, change coating step, top treatment step) are the same as described above.

<Expansive Utilization of the Present Invention> The wall mounting method of the present invention is not limited to the form applied on-site to the wall material fixed to the building, but also the wall panel processed in advance in a factory or the like. It can also be applied to mass-produced products such as. Further, it can be provided as a kind of a decorative article such as a picture to be attached to a wall, for example, in the form of being housed in an appropriate frame.

[0043]

According to the wall lining method of the present invention comprising the steps as described above, the base adjustment coating material is applied in a slightly thicker thickness in the undercoating step, and the surface thereof is designed to have various patterns by artificial work. By forming all the undulations, it is possible to freely and broadly express design from natural stone-like natural irregularities to concrete three-dimensional patterns such as murals and crafts. Then, by the intermediate coating step of applying the first ceramic coating material over the entire surface, it is possible to impart a stone-like and solid texture to the entire coated surface. Furthermore, the texture and color tone can be further deepened by the top coating step of partially applying the second ceramic coating material or the silicone resin-based, urethane resin-based, acrylic resin-based, or fluororesin-based colored coating material. By emphasizing the shades of undulations and changes in color tone, it is possible to obtain an extremely three-dimensional finish. In this way, it is possible to provide a wall covering that is rich in design expression and luxury.

Further, by using the ceramic coating material suitable for thickening, the undercoating step and the intermediate coating step are performed in the same step (undercoating / intermediate coating step), so that the steps can be shortened.
Man-hours and construction costs can be reduced.

The wall construction method of the present invention can be applied to almost all general base wall materials for inner walls and outer walls regardless of whether they are newly constructed walls or renovated walls. Furthermore, since the coating materials that have been widely used in the past are used in combination, the construction cost is low, the construction is easy, and the reliability of quality is high.
