The cosmetic part 12 represents the design of the finished wall surface, and the base part 13 can be painted or the like. Alternatively, it can be obtained by attaching a flexible member to the base 13 or the like.

  Although a general paint can be used for this coating, the coating film after drying needs to have flexibility. It is preferable to use a colored aggregate-containing coating material in which natural stone and its crushed stone, colored aggregate, colored plastic particles, plastic crushed particles and the like are mixed with a synthetic resin emulsion or a solvent-type synthetic resin.

By using this coloring aggregate-containing coating material, the design of the flexible sheet-like covering material 11 is improved, and the design feeling of the wall surface finished using it is also improved.
Although the base material part 13 supports the decorative member 12, it is also possible to adjust the suction of the adhesive and the adhesive when the flexible sheet-like covering material 11 is attached to the wall by the adhesive and the adhesive. is there.

In addition, the base portion 13 for improving the tensile, bending, and tear strength of the entire flexible sheet-like covering material 11 is an important factor.
The base portion 13 may be a sheet of a relatively thin material such as woven fabric, non-woven fabric, glass cloth, ceramic paper, synthetic paper, etc., or a material obtained by treating them, or a relatively thin plate made of plastic or metal or a sheet of polymer cement mortar. There are also molded ones.

Thus, the flexible sheet-like covering material 11 can be obtained by applying a paint or the like to be the decorative material part 12 to the base material part 13, drying and curing it, and laminating and forming a composite.
The flexible sheet-like covering material 11 preferably has a size of 1200 × 1200 mm or less, which is easy to attach to the wall surface and designed, and its weight is preferably in the range of 1 to 10 kg / m ² .

If the weight per this m ^2, flexible type sheet face material 11 becomes a design with a voluminous, it is capable of adhering without deviation.
The flexible sheet-like covering material 11 has flexibility, and as the flexibility, the covering material is bent along a cylinder having a diameter of 60 cm, and at that time, a crack, a crack or the like on the surface of the covering material Judging from the occurrence of no, there shall be no abnormality.

The thickness of the flexible sheet-like covering material 11 is preferably in the range of 2 to 15 mm, and the size thereof is more preferably in the range of 300 to 900 mm. Within this range, the handling and construction, and the design of the finished wall surface will be good.
As a preferred embodiment, adhesive processing parts 14 are provided on the four sides of the back surface of the flexible sheet-like covering material 11, and the adhesive processing parts 14 are protected by a release paper 15.

With such a form, by sticking the flexible sheet-like covering material 11 while peeling off the release paper 15, it is possible to stick to the adhesive part of the joint member described later, and it becomes stronger and more instantaneous The four circumferences of the flexible sheet-like covering material 11 can be fixed to the wall surface.
Furthermore, the flexible sheet-like covering material 11 does not shift before the adhesive is cured and dried, and the bonding can be performed reliably.

The width of the tacking portion 14 is preferably in the range of 5 to 30 mm. Within this range, the end of the flexible sheet-like covering material 11 can be sufficiently adhered. The adhesive material of the adhesive processing part 14 is not particularly limited, and known materials can be used.
Acrylic rubbers and non-vulcanized butyl rubbers are particularly preferable due to the availability thereof, and silicone rubbers, styrene butadiene rubbers, polyisoprenes and polyvinyl ethers may be used.

Further, as the release paper 15, a paper obtained by applying a fluororesin or a silicone resin, which is a known material used for an adhesive tape, a label or the like, can be used.
It is preferable to use tapes or the like in which the adhesion processing unit 14 and the release paper 15 are integrated, because the processing becomes simple.

There is a double-sided tape in this type of tape, and the one on which the adhesion processing part 14 and the release paper 15 are integrated is used on the other side of the adhesive material and the base material of the back surface of the flexible sheet-like covering material 11 It can process easily by sticking on the four sides of the part 13.
Aside from using a double-sided tape, it can be obtained by a method such as coating an adhesive with a fixed width and forming an adhesive processed portion 14 and then covering and protecting the adhesive processed portion 14 with a release paper 15. .

Next, an example of the joint member is shown in FIG. The joint member 21 is a roll-like or strip-like long member having a constant width of about 20 to 100 mm, and has an adhesive portion 23 covered with a release paper 24 on both sides in the longitudinal direction.
The base portion 22 of the joint member 21 is preferably made of a relatively thin 1 mm or less such as woven fabric, non-woven fabric, glass cloth, ceramic paper, synthetic paper, etc.

In the case of 1 mm or more, a step is formed between the portion where the joint member 21 is attached and the portion where the joint member 21 is not attached, and even if the flexible sheet-like covering material 11 is attached over the step, it may not be hidden. May be affected.
More preferably, it is 0.5 mm or less, and in that case, the level difference can be made inconspicuous by the flexibility of the thickness of the flexible sheet-like covering material 11 and the softness thereof.

  The width of the adhesive portion 23 is preferably in the range of 5 to 30 mm, and within this range, the end portion of the flexible sheet-like covering material 11 can be adhered sufficiently. The pressure-sensitive adhesive material is not particularly limited, and known materials can be used, but acrylic rubber-based or non-vulcanized butyl rubber-based ones are particularly preferable due to the availability thereof and the like, and other silicones Rubber type, styrene butadiene rubber type, polyisoprene type, polyvinyl ether type and the like can be used.

As the release paper 24, a paper obtained by applying a fluorocarbon resin or a silicone resin, which is a known material generally used for an adhesive tape, a label or the like, can be used.
It is preferable to use a tape or the like in which the adhesive portion 23 and the release paper 24 are integrated, because the processing becomes simple.

This tape includes the double-sided tape described above, and the adhesive unit 23 and the release paper 24 are integrally attached to one side of the base portion 22 in the longitudinal direction using the adhesive material on the other side. Can be processed.
Other than using a double-sided tape, there is a method of applying an adhesive material with a fixed width, forming an adhesive part 23 and then covering the adhesive part 23 with a release paper 24 for protection.

The adhesive portions 23 on both sides in the longitudinal direction of the joint member 21 can be disposed without providing a fixed distance, but it is also possible to provide a distance in the range of 3 to 15 mm, in which case, It is preferable to use an adhesive part covered with release paper on both sides in the longitudinal direction of the joint member 21 with an interval of 3 to 15 mm.
By using this joint member 21, it is possible to easily make a certain interval.

In the case of using the joint member 21 in the case of leaving a certain interval, the joint member 21 for the interval is exposed on the wall surface finished thereby, and the exposed portion represents the design as the joint It becomes a thing.
Moreover, it is also possible to give a function to the joint member 21 and to exhibit the function from the exposed portion.

The functions include waterproofness and moisture permeability. In order to add such a function, a paint or the like having that function is used as a treatment material.
As an example of this function, a paint that forms a moisture-permeable coating film is used as a dressing treatment material, and the exposed portion is provided with moisture permeability performance. Thereby, the dew condensation water which generate | occur | produces in a wall can be discharge | released outside.

The object wall surface is finished using the flexible sheet-like covering material 11 and the joint member 21.
First, pretreatment such as ground adjustment and primer treatment is performed on the target wall surface as necessary. The pretreatment such as base preparation and primer treatment is intended to improve the smoothness of the target wall surface to improve the finish or to improve the adhesion of the flexible sheet-like covering material 11 and the joint member 21. It is.

Next, assuming the finish of the wall surface, allocation of the attachment position of the flexible sheet-like covering material 11 is determined, and the position where the joint member 21 is attached is marked on the wall surface.
This allocation varies depending on the size of the flexible sheet-like covering material 11, but is determined so as to be evenly and uniformly arranged on the target wall surface.

According to the determined allocation, the position where the joint member 21 is to be attached is marked and attached so that the four turns of the flexible sheet-like covering material 11 can be the position where the adhesive portion 23 of the joint member 21 can be covered. An example of the state which affixed the joint member 21 is shown in FIG.
In the one shown in FIG. 3, the joint member 21 to be attached in the lateral direction is attached first, and then the joint member 21 in the longitudinal direction is attached. The way of pasting is not particularly limited, and is selected from assignment, work efficiency, and the like.

The joint member 21 is often attached using an adhesive or an adhesive, and these are not particularly limited, but synthetic rubbers, vinyl acetates, polymer cements, acrylic rubbers, Various adhesives and adhesives such as denatured silicon can be used.
Further, as these forms, there are a solvent type using an organic solvent as a solvent, an aqueous type using water, and a non-solvent type not using them. The solvent type is preferably used.

This adhesive is often applied by a coating roller used for spatula, iron or coating, etc., and application is performed to the portion where the joint member 21 is to be attached. By using such a device, work can be performed efficiently.
After applying the adhesive, the joint member 21 is attached. The adhesive is often applied slightly wider than its width in order to securely bond the joint member 21.

It is preferable to remove the adhesive protruding from the joint member 21 so that no level difference is left. If the adhesive used here remains and the flexible sheet-like covering material 11 is attached after that with the step, the step may not be concealed.
When the joint member 21 is attached in this manner, a space 31 surrounded by the release paper 24 is formed. The space 31 is a portion where the base of the wall surface is exposed. An adhesive is applied to this portion, and the flexible sheet-like covering material 11 is attached. An example of the process of affixing is shown in FIG. The process of FIG. 4 is performed on the target wall surface 41.

As the adhesive 42, the adhesive used for attaching the joint member 21 can be used, and the adhesive can be applied using a similar device.
When the adhesive material 42 is applied to the space 31, the periphery is protected by the release paper, and even if it slightly protrudes, there is no influence, so that the entire space 31 can be reliably applied to every corner without spots.

Thus, the adhesive 42 is applied within the range of a prescribed amount, and the flexible sheet-like facing 11 is attached. When affixing the flexible sheet-like covering material 11, the release paper 24 in the joint member 21 is peeled off to expose the adhesive portion 23, and the four peripheries of the flexible sheet-like covering material 11 are adhered. Bond with adhesive.
By bonding the four circumferences of the flexible sheet-like covering material 11 with the adhesive 23, it can be instantaneously fixed, and the flexible sheet-like covering material 11 is fixed until the adhesive material 42 cures and dries. can do.

By finishing the wall surface in this way, the adhesive 42 can be easily applied to the wall surface, enabling efficient finishing work and sufficient adhesion of the flexible sheet-like covering material after attachment. It is a thing.
Furthermore, a space of 3 to 15 mm can be provided between adjacent flexible sheet-like coverings by using adhesive members 23 on both sides in the longitudinal direction of joint member 21 with a gap of 3 to 15 mm. Therefore, the interval becomes the exposed portion of the joint member 21 and is expressed as a joint, and the finish of the wall surface can be excellent.

It is also possible to place a sealing material on the joint where the joint member 21 is exposed, whereby the waterproof performance of the wall surface after finishing can be further improved.
As the sealing material used for this, known sealing materials are used, and there are silicone type, modified silicone type, polysulfide type, acrylic urethane type, urethane type and acrylic type. Among these, silicone-based or modified silicone-based ones are preferable from the viewpoint of moisture permeability, and modified silicone-based and polysulfide-based sealing materials are suitable from the viewpoint of contamination resistance.

The hardness and viscosity of the sealing material may be the same as the range used as a building sealing material, and can be used without problems if it is within 20 seconds which is a standard in extrudability of the JISA 5758 building sealing material.
The shape of this placed joint can be filled into the entire space provided, and can be a flat joint made flat or a slightly rounded pudding joint. In this case, it is possible to drive using a commonly used sealing gun.

  In addition, the corner portion formed by the flexible sheet-like covering material 11 and the joint member 21 has a substantially triangular cross section not more than the thickness of the flexible sheet-like covering material 11 of 0.5 mm to 3.0 mm or less. It is preferable to place the joint member 21 so that the exposed portion of the joint member 21 can be effectively used and the amount of sealing material used is also reduced.

Drying and curing may be accelerated by using less sealing material.
Further, since the sealing material protruding to the flexible sheet-like covering material 11 is eliminated by placing the sealing material at a thickness equal to or less than the thickness of the flexible sheet-like covering material 11, the surface of the flexible sheet-like covering material 11 is Work efficiency can be improved because work can be performed without curing.

Further, in this case, the sealant syringe having a nozzle diameter of 0.5 to 3.0 mm is used to drive the corner portion formed by the flexible sheet-like covering material 11 and the joint member 21.
In this way, casting is possible with a substantially triangular cross section. Even if the cross-sectional shape of the nozzle is circular, a substantially triangular cross-section can be obtained by applying a sealing material so as to hold it down. In addition, if the tip of the nozzle is obliquely cut like an injection needle, it can be carried out in a state where the surface is flat and the surface is not raised.

The color tone of the sealing material is preferably similar to that of the joint member 21 and may be transparent.
By being a thing of a similar color, and being transparent, it becomes a thing which looks like the sealing material and the joint member 21 were united, and there is no sense of incongruity.
By using similar colors, it is possible to hide the sticking adhesive 23 that has run out.

Furthermore, it is preferable that the adhesive processed portions 14 be provided on the four sides of the back surface of the flexible sheet-like covering material 11, protected by the release paper 15, and the covering material 11 be affixed while peeling off the release paper 15. By doing this, the adhesion of the end portion of the covering material 11 becomes more reliable.
The same adhesive processing section 14 as the adhesive section 23 of the joint member 21 can be used as the adhesive processing section 14, and the same release paper as the release paper 24 of the joint member 21 can be used as the release paper 15.

Further, a double-sided tape is also preferably used, and since an adhesive processing unit 14 and a release paper 15 can be used integrally, the processing can be easily performed. Alternatively, after a pressure-sensitive adhesive material is applied with a constant width to form a pressure-sensitive adhesive processed portion 14, the pressure-sensitive adhesive processed portion can be covered and protected with a release paper 15.
The width of the adhesion processing part 14 corresponds to the width of the adhesion part 23 of the joint member 21, and the size of the adhesion processing part 14 is matched to the adhesion part 23 of the joint member 21 to be used. Therefore, the width is preferably in the range of 5 to 30 mm.
