Description

This disclosure relates to a method for finishing walls, such as interior and exterior walls of buildings and other structures, and its field of application is the construction field.

Many methods for finishing walls have been proposed in the past, and among them, Japanese Patent Application Laid-Open No. 05-209453 proposes a method for finishing a flexible sheet-like covering material.
This describes a method using a flexible covering material which, when viewed from the front, consists of a decorative part, a base material part, an adhesive part, and a release paper part, and a roll- or strip-shaped joint member which, when viewed from the front, consists of a base material part, an adhesive part, and a release paper part; the joint member is applied first after calculating the size of the covering material and the joint spacing, and then a flexible sheet-like covering material is adhered to a specified position with the adhesive while the release paper is peeled off.

This allows the flexible sheet-type covering material and joint members to be prepared, the joint members to be pre-applied to the joint formation location, and the flexible sheet-type covering material to be used to easily finish the wall surface while providing the desired joint spacing.

Japanese Patent Application Laid-Open No. 05-209453

In this type of wall finishing method, after the joint members have been applied, the flexible sheet-like covering material can be applied from any part, allowing the finishing work to be carried out efficiently.
However, when joint members are attached in this manner, there is no connectivity between the joint members adjacent to them, and it may not be possible to obtain sufficient strength for the wall or sufficient effects in terms of repairing the wall.

For example, when renovating a wall surface that is covered with tiles or stone, the finishing method described in Patent Document 1 may result in the flexible sheet-like covering material and the joint members adhered to it becoming independent, and the entire wall surface may not be in a unified state.
Therefore, when tiles or stones come off from the old wall surface, the flexible sheet-like covering material attached to them may come off together with them.

The present disclosure aims to provide a method for finishing walls that integrates the surfaces of the walls of a structure, prevents the materials that make up the old wall surface from peeling off, and is relatively easy to finish, resulting in a good finish.

A method for finishing the wall surface of a structure, in which multiple strip-shaped reinforcing members are attached at regular intervals in the vertical direction to the surface to be finished, and then multiple strip-shaped reinforcing members are attached at regular intervals in the horizontal direction while being attached to the vertical strip-shaped reinforcing members, so that the surface to be finished is covered in a mesh pattern with the vertically attached strip-shaped reinforcing members and the multiple horizontally attached strip-shaped reinforcing members, and a flexible sheet-like covering material is attached to the surface to be finished that is covered in the mesh pattern.

This allows the band-shaped reinforcing members to be attached to areas such as corners such as protruding or recessed corners in the vertical direction of the surface to be finished, the left and right sides of an opening, and the vertical ends of the surface to be finished, and then the horizontal band-shaped reinforcing members can be attached using these as starting points. This allows the band-shaped reinforcing members to be integrated into a mesh-like structure, and prevents the material that makes up the old wall surface from peeling off, starting from the vertical band-shaped reinforcing members. As the finishing can be done based on the band-shaped reinforcing members, a relatively easy and good finish can be obtained.

A method for finishing the wall surface of a structure, in which multiple strip-shaped reinforcing members are attached at regular intervals in the horizontal direction of the surface to be finished, and then multiple strip-shaped reinforcing members are attached at regular intervals in the vertical direction while being attached to the horizontal strip-shaped reinforcing members, so that the surface to be finished is covered in a mesh pattern with the horizontally attached strip-shaped reinforcing members and the multiple vertically attached strip-shaped reinforcing members, and a flexible sheet-like covering material is attached to the surface to be finished that is covered in the mesh pattern.

This allows the band-shaped reinforcing members to be attached to areas such as the story level, eaves, and upper and lower parts of openings that are in the horizontal direction of the surface to be finished, as well as the horizontal edges of the surface to be finished, and then vertical band-shaped reinforcing members can be attached using these as starting points. This allows the band-shaped reinforcing members to be integrated into a mesh-like structure, and prevents the material that makes up the old wall surface from peeling off, using the horizontal band-shaped reinforcing members as starting points. The finishing can also be done using the band-shaped reinforcing members as a base, making it relatively easy to obtain a good finish.

In a compartment formed from a plurality of band-shaped reinforcing members attached vertically and horizontally, two or more adjacent compartments are grouped together, and adhesive is applied to each compartment or group of compartments, and the flexible sheet-like covering material is attached so that the ends thereof are near the center of the band-shaped reinforcing members.
This ensures that the adhesion between the flexible sheet-like covering material and the band-like reinforcing member is even on both sides, preventing the material that makes up the old wall surface from peeling off.

The adhesive portions covered with release paper are spaced apart in the range of 3 to 15 mm on both sides of the longitudinal direction of the belt-shaped reinforcing member, and a space in the range of 3 to 15 mm is provided between the ends of adjacent flexible sheet-like covering materials, exposing the belt-shaped reinforcing member.
This makes the finishing easier, resulting in a decorative finish, ensures uniform adhesion between the flexible sheet-like covering material and the band-like reinforcing member on both sides, and prevents the material that makes up the old wall surface from peeling off.

An example of a finishing method for a surface to be finished will be described. 3 shows an example of a belt-shaped reinforcing member. An example of a flexible sheet-like surface layer material is shown. 1 shows an example of the back surface of a flexible sheet-like surface material.

An embodiment of the present disclosure will be described. Figure 1 shows an example of a finishing method for a surface to be finished, such as a wall surface.

First, multiple strip-shaped reinforcing members 12 are attached at regular intervals in the vertical direction on the surface to be finished 11 in the viewing direction A, and then multiple strip-shaped reinforcing members 12 are attached at regular intervals in the horizontal direction while being attached to the vertical strip-shaped reinforcing members 12, so that the surface to be finished 11 is covered in a mesh-like pattern by the vertically attached strip-shaped reinforcing members 12 and the multiple horizontally attached strip-shaped reinforcing members 12, forming multiple sections 13, and then a flexible sheet-like covering material 14 is attached to the surface to be finished 11 covered in the mesh-like pattern.

In addition, multiple strip-shaped reinforcing members 12 are attached at regular intervals in the horizontal direction of the surface to be finished 11 in the B viewing direction, and then multiple strip-shaped reinforcing members 12 are attached at regular intervals in the vertical direction while being attached to the horizontal strip-shaped reinforcing members 12, so that the finished surface is covered in a mesh-like pattern by the horizontally attached strip-shaped reinforcing members 12 and the multiple vertically attached strip-shaped reinforcing members 12, forming multiple sections 13, and a flexible sheet-like covering material 14 is attached to the finished surface 11 covered in the mesh-like pattern.

On the surface to be finished 11 in the viewing direction A, the band-shaped reinforcing members 12 are attached to corners such as vertical outside corners 15 and inside corners 16, vertical edges 17, and other areas such as the left and right sides of an opening.
Since horizontal band-shaped reinforcement members 12 can be attached starting from the previously attached vertical band-shaped reinforcement members 12, the band-shaped reinforcement members 12 can be integrated into a mesh-like structure, thereby preventing the material that makes up the old wall surface, which is the surface to be finished 11, from peeling off.

Furthermore, since the finishing can be carried out based on the belt-shaped reinforcing member 12, it is relatively easy to obtain a good finish.
In the finishing surface 11 in the B viewing direction, the band-shaped reinforcing members 12 are attached from areas such as the horizontal story portions, eaves, upper and lower parts of openings, and the horizontal edges 17 of the target surface.

Since the vertical reinforcing band-shaped members 12 can be attached starting from the horizontal reinforcing band-shaped members 12 that have been attached previously, the reinforcing band-shaped members 12 can be integrated into a mesh-like structure, thereby preventing the material that makes up the old wall surface, which is the surface to be finished 11, from peeling off.
Furthermore, since the finishing can be carried out based on the belt-shaped reinforcing member 12, it is relatively easy to obtain a good finish.

In many cases, the surface 11 to be finished will be the wall surface of a structure such as an architectural or civil engineering structure, and the constituent base materials will be concrete, mortar, metal, wood, glass, wallboard materials, panels, and the like.
These wallboard materials include ceramic siding boards, flexible boards, calcium silicate boards, extrusion molded 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.

Furthermore, some panels are made of a plurality of base materials or wallboard materials and have decorative surfaces.
In the present disclosure, the effect is more pronounced in cases where the base material constituting the wall surface is composed of multiple wall boards or panels, or where these surfaces are painted with paint or the like, or where the surface of the wall surface is an existing finished surface with a fixed object such as a tile attached.

In the case of such a finishing target surface 11, cracks may occur in the wall surface as the structure moves, and in some cases, wall panels, tiles, and other materials that make up the wall surface may peel off.
In addition, paints and other coatings are formed on the surface for coloring and to protect the wall, and these coatings can develop defects due to partial deterioration over time, or the coating can peel off. In some cases, the base material that makes up the wall can be damaged, such as by cracks or chips.

By attaching multiple strip-shaped reinforcing members 12 vertically and horizontally and integrating them into a mesh-like structure, it is possible to prevent the material that constitutes the surface to be finished 11 from peeling off, and because the finishing can be done based on the strip-shaped reinforcing members 12, it is possible to obtain a relatively easy and good finish.

The belt-shaped reinforcing member 12 is preferably flexible so that it can easily adapt to undulating conditions.
Even within the finishing surface 11 where this band-shaped reinforcing member 12 is attached, in the case of repairs involving deterioration over time, there are few straight lines and many wavy lines, and this tendency is particularly strong at corners such as protruding corners 15 and recessed corners 16, where there are few straight lines.

For this reason, the belt-shaped reinforcing member 12 can be made of metal or plastic, but it is preferable to use a relatively thin material having a thickness of 1 mm or less, such as flexible woven fabric, nonwoven fabric, glass cloth, ceramic paper, synthetic paper, or any of these that have been sealed.
If the thickness is more than 1 mm, a step will be created with the base, and when a finishing material is used, the step may deteriorate the design of the flexible sheet-like covering material 14. Even if this step is to be eliminated, if the step is large, exceeding 1 mm, the work becomes time-consuming and difficult.

When the reinforcing member 12 is thin and flexible, being 1 mm or less in thickness, it is possible to make the reinforcing member 12 in a roll form, and it can be cut to any desired length for use, allowing efficient work.
Furthermore, as shown in FIG. 2, the belt-shaped reinforcing member 12 may have adhesive portions 22 covered with release paper 21 on both sides in the longitudinal direction thereof, the adhesive portions being spaced apart from each other by a distance in the range of 3 to 15 mm.

When a band-shaped reinforcing member 12 as shown in Figure 2 is used, it becomes easier to provide a space in the range of 3 to 15 mm between the ends of adjacent flexible sheet-like covering materials 14 described below, and this space can be used as a joint.
By utilizing this adhesive portion 22, the flexible sheet-like covering material 14 is attached while peeling off the release paper 21, so that the end of the flexible sheet-like covering material 14 is reliably adhered, finishing can be easily performed, and a finish with excellent design can be obtained.

Since the adhesive is applied to the area surrounded by this belt-shaped reinforcing member 12, the adhesive portion can be protected by the release paper 21.
In addition, by providing adhesive portions 22 at equal positions on the left and right sides of the band-shaped reinforcing member 12, the adhesion between the flexible sheet-like covering material 12 and the band-shaped reinforcing member 14 is equal on the left and right sides, preventing the material constituting the old wall surface from peeling off.

The width of the adhesive portion 22 is preferably in the range of 5 to 30 mm, and within this range, the edge of the flexible sheet-like covering material 14 can be adhered sufficiently.
The adhesive of the adhesive portion 22 is not particularly limited, and any known adhesive can be used. In view of ease of availability, acrylic rubber-based or non-vulcanized butyl rubber-based adhesives are particularly preferable, although silicone rubber-based, styrene butadiene rubber-based, polyisoprene-based, polyvinyl ether-based, etc. can also be used.

The release paper 21 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 portion 22 and the release paper 21 are integrated are preferably used because they are easy to process.
This type of tape includes double-sided tape, which is an integrated adhesive portion 22 and release paper 21, and can be processed by attaching the combined tape to both sides of the belt-shaped reinforcing member 12 in the longitudinal direction using adhesive on the other side.

Other than using double-sided tape, there is a method in which an adhesive is applied to a certain width to form an adhesive portion 22, and then the adhesive portion 22 is covered with a release paper 21 for protection.
This band-shaped reinforcing member 12 is long and has a certain width, and its length is not particularly limited, but in the case of the viewing direction A in Figure 1, it is preferable that it is the height of the surface to be finished 11, and in the case of the viewing direction B, it is the length in the width direction.

Furthermore, if there is an opening such as a window on the finishing surface 11, it is preferable that the length is to the opening. However, it is desirable that the length is the vertical length of the finishing surface 11 of the structure, but from the viewpoint of work efficiency, it is preferable that the length is at least the length of the story of the structure in the vertical direction.
In addition, in the case of the A viewing direction, multiple strip-shaped reinforcing members 12 may be attached in the vertical direction at regular intervals, and the length of the strip-shaped reinforcing members 12 then attached in the horizontal direction may be the length connecting adjacent strip-shaped reinforcing members 12 attached in the vertical direction.

In the case of the B viewing direction, multiple strip-shaped reinforcing members 12 are attached horizontally at regular intervals, and the length of the strip-shaped reinforcing members 12 attached vertically thereafter may be the length connecting adjacent strip-shaped reinforcing members 12 attached horizontally.
Furthermore, if such a strip-shaped reinforcing member 12 is flat, it can be folded before being attached, so that it can be easily processed into the shape of an external corner 15 or an internal corner 16, and the surface 11 to be finished can be reinforced to match the shape of the corner, allowing for efficient work.

The width of this band-shaped reinforcing member 12 is preferably in the range of 20 to 100 mm. If it is narrower than 20 mm, the strength will be reduced and the effect of integrating the surface of the surface to be finished 11 and preventing the material constituting the surface to be finished 11 from peeling off will be reduced.
If the width is wider than 100 mm, the application will be time-consuming and it may be difficult to fit the finishing materials later.

Such a belt-like reinforcing member 12 is attached to the surface to be finished 11. In this attachment, the position on the surface to be finished 11 where the belt-like reinforcing member 12 is to be attached is confirmed and marked in advance.
The markings are often followed by the use of an adhesive or pressure sensitive adhesive, and although there are no particular limitations, various types of adhesives and pressure sensitive adhesives can be used, such as synthetic rubber, vinyl acetate, polymer cement, acrylic rubber, modified silicone, etc.

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.
The adhesive is often applied with a spatula, a trowel, a paint roller used for painting, etc., and is applied to the area where the belt-shaped reinforcing member 12 is to be attached. By using such tools, the work can be performed efficiently.

After the adhesive is applied, the belt-shaped reinforcing member 12 is attached. In order to reliably bond the belt-shaped reinforcing member 12, the adhesive is often applied to an area slightly wider than the width of the belt-shaped reinforcing member 12.
It is preferable to remove the adhesive that protrudes from the belt-shaped reinforcing member 12 so as not to leave a step. If finishing is carried out later while the adhesive used here remains and there is a step, the step may not be completely hidden.

Alternatively, the back surface of the belt-shaped reinforcing member 12 may be previously subjected to adhesive processing, and then the resultant surface may be attached to the surface to be finished 11. This prevents the adhesive from spilling out when applying the adhesive or when adhering the belt-shaped reinforcing member 12.
In this manner, a long strip-shaped reinforcing member 12 having a constant width is attached to the surface 11 to be finished.

A plurality of strip-shaped reinforcing members 12 are attached at regular intervals in the vertical direction to the surface 11 to be finished in the viewing direction A. In many cases, the reinforcing members are attached in the order of the outside corner 15, the inside corner 16, and the end portion 17, or from the left or right side, but the order of attachment is not particularly limited.
Thereafter, a plurality of horizontally extending strip-shaped reinforcing members 12 are attached to the vertically extending strip-shaped reinforcing members 12 at their intersections 18 at regular intervals, and are then attached to the surface to be finished 11. The surface to be finished is covered in a mesh pattern by a plurality of sections 13 formed from the plurality of vertically and horizontally extending strip-shaped reinforcing members 12.

The intersections 18 can be bonded using the adhesive material described above, or can be bonded using a pressure sensitive adhesive or double-sided tape.
Next, a flexible sheet-like covering material 14 is applied to the surface to be finished that is covered in a mesh pattern.

This flexible sheet-like covering material 14 is attached to the surface to be finished 11 to finish the surface, protect the wall and add a decorative element. It is used for finishing the interior and exterior wall surfaces of architectural structures and is generally quadrilateral in shape, such as a rectangle or square.
The surface is expressed by coloring such as printing or painting, by creating an uneven shape, or by a combination of these.

Because this flexible sheet-like surface material 14 is flexible, it can follow the movement of the finishing surface 11 to which it is attached over time, and can prevent the material that makes up the old wall surface from peeling off.
The flexible sheet-like covering material 14 is preferably sized at 1200×1200 mm or less for ease of application to the wall surface and for design reasons, and its weight is preferably in the range of 1 to 10 kg per ^m2 .

With this weight per ^square meter, the flexible sheet-like covering material 14 can have a voluminous design and can be adhered without shifting.
This flexible sheet-like covering material 14 has flexibility, and this flexibility is judged by bending the covering material along a cylinder with a diameter of 60 cm and checking whether or not cracks or breaks occur on the surface of the covering material, and this is deemed to be normal.

The thickness of the flexible sheet-like covering material 14 is preferably in the range of 2 to 15 mm, and the size is more preferably in the range of 300 to 900 mm. If it is within this range, it will be easy to handle and install, and the design of the finished wall surface will be good.
A typical example of this flexible sheet-like surface layer material 14 is as shown in FIG. 3, which has a decorative material portion 31 on the front side and a base material portion 32 for supporting the decorative material portion 31 on the back side.

The decorative material portion 31 expresses the design of the finished wall surface, and can be obtained by painting the base material portion 32. Alternatively, it can be obtained by attaching a flexible member to the base material portion 32.
For this coating, general paints and coating materials can be used, but the coating film must be flexible after drying. Preferably, the paint or coating material can be made thicker.

One example is the use of a coating material containing colored aggregate, which is made by mixing natural stone or crushed stone, colored aggregate, colored plastic granules, or crushed plastic granules with a synthetic resin emulsion or a solvent-based synthetic resin.
By using this colored aggregate-containing coating material, the design of the flexible sheet-like covering material 14 is improved, and the design of the wall surface finished with it is also improved.

The base material portion 32 supports the decorative member 31, but also has the effect of adjusting the absorption of adhesive or glue when the flexible sheet-like covering material 14 is attached to a wall surface with an adhesive or glue.
Further, in order to improve the tensile, bending and tear strength of the entire flexible sheet-like covering material 14, the base material portion 32 is an important element.

The substrate 32 may be a relatively thin material such as woven fabric, nonwoven fabric, glass cloth, ceramic paper, synthetic paper, or a material that has been sealed, or may be a plate-shaped material made of plastic or metal, or a sheet-shaped material made of polymer cement mortar.
The flexible sheet-like covering material 14 can be obtained by applying paint or the like that will become the decorative material portion 31 to the base material portion 32, drying and hardening it, and laminating and compounding it.

In a preferred embodiment, the flexible sheet-like covering material 14 shown in FIG. 4 has adhesive sections 41 on all four sides of the back surface thereof, and the adhesive sections 41 are protected by release paper sections 42 .
By using this type of configuration, the release paper portion 42 can be peeled off while the flexible sheet-like covering material 14 is attached, thereby allowing the adhesive processed portion 41 to be attached to the band-shaped reinforcing member 12, and the four sides of the flexible sheet-like covering material 14 can be fixed more firmly and instantly to the wall surface.

Furthermore, the flexible sheet-like covering material 14 does not shift during the time until the adhesive hardens and dries, and can be reliably adhered.
The width of the adhesive processed portion 41 is preferably in the range of 5 to 30 mm, and within this range, it is possible to sufficiently adhere the edge of the flexible sheet-like covering material 14. The adhesive of the adhesive portion 22 is not particularly limited, and any known adhesive can be used.

The adhesive may be the same as the adhesive used for the belt-shaped reinforcing member 12 shown in FIG.
The release paper portion 42 is a known material that is normally used for adhesive tapes, labels, etc., and may be the same as the release paper 21 used for the belt-shaped reinforcing member 12 shown in FIG.

It is preferable to use a tape or the like in which the adhesive processed portion 41 and the release paper portion 42 are integrated, since this simplifies processing.
This type of tape is available as double-sided tape, and has an adhesive processing section 41 and a release paper section 42 integrated together. By using adhesive on the other side of the tape, the tape can be easily processed by adhering the tape to the four sides of the base material section 32 on the back surface of the flexible sheet-like covering material 14.

Other than using double-sided tape, it can also be obtained by applying an adhesive to a certain width to form an adhesive processed portion 41, and then covering and protecting the adhesive processed portion 41 with a release paper portion 42.
By using the band-shaped reinforcing member 12 shown in Figure 2 described above and the flexible sheet-like covering material 14 shown in Figure 4, in which adhesive processing has been applied to all four sides of the base material portion 32 on the back surface thereof, the adhesion between the adhesive processing portions 41 on the four sides of the flexible sheet-like covering material 12 and the adhesive portions 22 of the band-shaped reinforcing member 12 can be made more sufficient.

The adhesive for attaching this flexible sheet-like surface material 14 is not particularly limited, but various adhesives such as synthetic rubber, vinyl acetate, polymer cement, acrylic rubber, and modified silicone can be used.
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 sections 13 of the surface 11 to be finished, which is covered in a mesh pattern, and then a flexible sheet-like surface material 14 is attached. This adhesive is often applied using a spatula, a trowel, or a paint roller used for painting, and the use of these tools allows the work to be carried out efficiently.
It is also possible to apply the adhesive to multiple sections 13 and then attach a flexible sheet-like surface material 14 to each of the applied sections 13, and after applying the adhesive, the number of flexible sheet-like surface materials 14 that can be attached within the open time of the adhesive will be attached.

Furthermore, it is also possible to group a plurality of compartments 13 into a compartment group, and attach a flexible sheet-like surface material 14 having a size corresponding to the size of the compartment group.
In this case, there will be portions on the surface of the band-shaped reinforcing member 12 of the compartments 13 that make up the compartment group where a flexible sheet-like surface material 14 will be attached, so adhesive will also be applied to the band-shaped reinforcing member 12 to which this flexible sheet-like surface material 14 will be attached.

This allows a large flexible sheet-like surface material 14 to be attached, making the attachment work more efficient.
In addition, the compartments 13 can be made into smaller units, which makes it possible to increase the number of strip-shaped reinforcing members 12, thereby making it possible to prevent the material constituting the old wall surface from peeling off.

The wall finishing method of the present disclosure is carried out using the above-mentioned constituent materials, and the method will be described in detail.
First, the surface to be finished 11 shown in FIG. 1 is a wall surface formed of concrete, and in order to make the surface smoother, a base adjustment material whose main component is cement was used and the wall surface was smoothed with a metal trowel.

The belt-shaped reinforcing member 12 and the sheet-shaped surface material 14 are attached to the smoothed wall surface with an adhesive, but prior to this, a general water-based primer whose main component is an acrylic synthetic resin emulsion is applied to improve adhesion.
In this manner, the surface to be finished 11 was prepared, and marks were made at the positions where the band-shaped reinforcing members 12 were to be attached. Following these marks, the band-shaped reinforcing members 12 were attached from the outside corners 15 and the inside corners 16 in the vertical direction of the surface to be finished 11 in the viewing direction A, so that the center of the band-shaped reinforcing member 12 was 600 mm away from the outside corners 15.

Then, using the band-shaped reinforcing member 12 attached to the protruding corner 15 as a starting point, band-shaped reinforcing members 12 were attached from the upper and lower horizontal ends 17 so that the center of the band-shaped reinforcing member 12 was 600 mm away from the upper end 17.
By attaching the band-shaped reinforcing members 12 in this manner, a plurality of sections 13 can be formed, and the surface 11 to be finished can be covered in a mesh-like pattern.

The belt-shaped reinforcing member 12 is a polyester nonwoven fabric that has been sealed with an acrylic paint, and has a width of 45 mm, a thickness of 300 μm, and a length of 50 m in roll form. Since it is in roll form, it was cut with scissors to an appropriate length that is equal to or greater than the height and width of the surface 11 to be finished.
The belt-shaped reinforcing member 12 attached to the protruding corner 15 was folded in half from the center in the width direction of the belt-shaped reinforcing member 12 before attachment, processed into the shape of the protruding corner 15, and attached to that shape.

For this bonding, an adhesive that uses an acrylic synthetic resin emulsion as a binder and becomes clear after drying was applied with a paint roller, and the belt-shaped reinforcing member 12 was attached.
The adhesive was applied to an area slightly wider than the width of the belt-shaped reinforcing member 12, and any adhesive that protruded beyond the belt-shaped reinforcing member 12 was removed so as not to leave any step.

This enabled multiple belt-shaped reinforcing members 12 to be attached in the vertical and horizontal directions, and the belt-shaped reinforcing members 12 to be integrated into a mesh-like structure.
Next, the flexible sheet-like surface layer material 14 is attached. The flexible sheet-like surface layer material 14 used has a decorative material portion 31 on the front side as shown in Fig. 3 and a base material portion 32 for supporting the decorative material portion 31 on the back side.

The decorative material portion 31 was obtained by applying a coating material containing colored aggregate to the base material portion 32. The base material portion 32 was made of a polyester nonwoven fabric.
The flexible sheet-like surface material 14 was attached by applying an adhesive containing an acrylic synthetic resin emulsion as a binder and a filler to each section 13 with a paint roller.

This flexible sheet-like surface material 14 was attached so that the end of the flexible sheet-like covering material 14 was near the center of the band-shaped reinforcing member 12, and the distance between the end of the flexible sheet-like surface material 14 and the end of the adjacent flexible sheet-like surface material 14 was 3 mm.
This makes it possible to attach a band-shaped reinforcing member 14 to a vertical protruding corner 15 of the surface to be finished 11, and then use this as a starting point to attach a horizontal flexible sheet-like surface material 14.The band-shaped reinforcing members can be integrated into a mesh-like structure, thereby preventing the material that makes up the surface to be finished 11 from peeling off.

In addition, the adhesion between the flexible sheet-like covering material 14 and the band-like reinforcing member 12 is even on the left and right sides, which improves the prevention of peeling off of the material constituting the surface to be finished 11, making it possible to obtain a relatively easy and good finish.
Next, strip-shaped reinforcing members 12 were attached to the upper and lower ends 17 of the surface to be finished 11 in the horizontal direction of the surface to be finished 11 in the B viewing direction, so that the center of the strip-shaped reinforcing member 12 was 600 mm away from the upper end 17.

Then, starting from the band-shaped reinforcing member 12 attached to the upper end 17, a band-shaped reinforcing member 12 was attached to the end 17 in the vertical direction, and from there, the centers of the band-shaped reinforcing members 12 were attached at intervals of 600 mm.
By attaching the band-shaped reinforcing members 12 in this manner, a plurality of sections 13 can be formed, and the surface 11 to be finished can be covered in a mesh-like pattern.

This belt-shaped reinforcing member 12 was made of polyester nonwoven fabric that had been sealed with an acrylic paint, and had adhesive portions 22 covered with release paper 21 spaced apart by 5 mm on both sides of the longitudinal direction of the belt-shaped reinforcing member 12, as shown in Figure 2.
The adhesive portion 22 and the release paper 21 were made of double-sided tape having a width of 20 mm, and the belt-shaped reinforcing member 12 made from this was 45 mm wide, 300 μm thick, and 50 m long in a roll.

Since the strip-shaped reinforcing member 12 is in a roll form, it is cut to an appropriate length equal to or greater than the widthwise length of the surface 11 to be finished, and used, and the length of the strip-shaped reinforcing member 12 to be attached vertically is cut to a length sufficient to connect adjacent strip-shaped reinforcing members 12 attached horizontally, and used.
For this bonding, an adhesive containing an acrylic synthetic resin emulsion as a binder and a filler was applied with a spatula, and the belt-shaped reinforcing member 12 was attached.

The adhesive was applied to an area slightly wider than the width of the belt-shaped reinforcing member 12, and any adhesive that protruded beyond the belt-shaped reinforcing member 12 was removed so as not to leave any step.
This enabled multiple belt-shaped reinforcing members 12 to be attached in the vertical and horizontal directions, and the belt-shaped reinforcing members 12 to be integrated into a mesh-like structure.

The flexible sheet-like surface material 14 used had a decorative material portion 31 on the front side as shown in Figure 3, as described above, and a base material portion 32 for supporting the decorative material portion 31 on the back side, and the back side was provided with an adhesive processed portion 41 and a release paper portion 42 as shown in Figure 4.
The adhesive portion 41 and the release paper portion 42 were made of the same double-sided tape having a width of 20 mm as used for the belt-shaped reinforcing member 12 described above.

When applying adhesive to this section 13, since the periphery is protected by release paper, even if the adhesive overflows a little, it has no effect, and the adhesive can be applied reliably and evenly to every corner of the entire section 13.
In this manner, the adhesive is applied within a specified amount, and the flexible sheet-like covering material 14 is attached. When attaching the flexible sheet-like covering material 14, the release paper 21 on the belt-like reinforcing member 12 is peeled off to expose the adhesive portion 22, and the four periphery of the flexible sheet-like covering material 14 is adhered, and the remaining portion is adhered with the adhesive.

This makes it possible to attach the strip-shaped reinforcing member 12 from the upper horizontal end 17 of the surface to be finished 11 and then attach the vertical strip-shaped reinforcing member 12 from this starting point, thereby preventing the material constituting the surface to be finished 11 from peeling off.
Moreover, the finishing is made easier, and a finish excellent in design can be obtained, and the adhesion between the flexible sheet-like covering material 14 and the belt-like reinforcing member 12 is made uniform on both sides, making it possible to better prevent peeling off.
