Description
本開示は、再塗装方法、この再塗装方法に用いる孔開け具、および再塗装方法により再塗装を行った建物に関するものである。 The present disclosure relates to a repainting method, a drilling tool used in the repainting method, and a building that has been repainted by the repainting method.
従来、既設の建物において、外壁あるいは屋根などの既設の建材の塗装膜に経年劣化が生じた場合、旧塗装膜の上から、上塗り再塗装を行うことにより外観品質の低下を抑えることは知られている（例えば、特許文献１参照）。
また、このような建物の建材に用いる塗料として、透湿性と防水性とを兼ね備えた塗料が知られている（例えば、特許文献２）。この塗料は、シリコン樹脂エマルションと、シリコン樹脂以外の合成樹脂エマルションとを含有するものであり、例えば、アクリルシリコン樹脂エマルションと、シリコン樹脂エマルションと、分散剤と、消泡剤と、成膜助剤と、着色顔料と、体質顔料と、ｐＨ調整剤とを配合したものが例示されている。
Conventionally, in existing buildings, when the coating film of existing building materials such as outer walls or roofs deteriorates over time, it is known that the deterioration of the appearance quality is suppressed by recoating the top coating on the old coating film. (For example, refer to Patent Document 1).
Moreover, the coating material which has both moisture permeability and waterproofness is known as a coating material used for the building materials of such a building (for example, patent document 2). This paint contains a silicone resin emulsion and a synthetic resin emulsion other than a silicone resin. For example, an acrylic silicone resin emulsion, a silicone resin emulsion, a dispersant, an antifoaming agent, and a film forming aid. And a combination of a color pigment, an extender pigment, and a pH adjuster.
しかしながら、従来の再塗装では、旧塗装膜の上に、単に新しく上塗りをして新塗装膜を形成するようにしていたため、以下に述べるような問題が生じることがあった。
塗装の際には、塗装膜の下に僅かな空隙部分が生じる場合がある。このような空隙は、作業品質によって生じることもあるが、特に、塗料に骨材を含んで塗装面に凹凸を付けるスタッコ塗装の際に生じやすい。
そして、このように塗装膜の下に空隙部分が存在すると、外気の寒暖差により空隙部分に結露が生じ、この部分が日射などにより温度が上昇した場合に、空隙内の空気および水分が膨張し、塗装膜が外方に膨らんで外観品質が低下するおそれがあった。
However, in the conventional repainting, the new coating film is simply formed on the old coating film to form the new coating film, which may cause the following problems.
When painting, a slight gap may be formed under the coating film. Such voids may occur depending on work quality, but are particularly likely to occur during stucco painting in which the paint includes aggregates and the painted surface is uneven.
If there is a void portion under the coating film in this way, condensation occurs in the void portion due to the temperature difference of the outside air, and when the temperature rises due to solar radiation, the air and moisture in the void expand. The coating film may swell outward and the appearance quality may deteriorate.
また、塗料として上記の特許文献２に記載の塗料のように透湿性を有する塗料を用いることで、上記の空隙部分で膨張した空気や水分（水蒸気）が塗装膜を通過して外方に放出され、上記の塗装膜に膨らみが生じる不具合を抑制することができる。 Further, by using a paint having moisture permeability like the paint described in Patent Document 2 above, the air or moisture (water vapor) expanded in the gap portion is released to the outside through the paint film. In addition, it is possible to suppress a problem that the above-described coating film bulges.
しかしながら、上塗りに用いたた塗料が透湿性を備えていても、上記特許文献１に記載のように再塗装を行って、複数の塗装膜を重ねた場合には、塗装膜の厚みが増す分だけ透湿性、通気性が低下する。このため、空隙内の空気、水分が膨張した場合に、塗装膜を通過させることができずに、上記のように塗装膜が膨らむおそれがあった。 However, even if the paint used for the top coating has moisture permeability, when repainting is performed as described in Patent Document 1 above and a plurality of coating films are stacked, the thickness of the coating film increases. Only moisture permeability and breathability are reduced. For this reason, when the air and moisture in the gap expand, the coating film cannot be passed through, and the coating film may swell as described above.
本開示は、既設建材の再塗装後の外観品質向上を図ることが可能な再塗装方法、この再塗装方法に用いる孔開け具および再塗装方法による新塗装膜を備える建物を提供することを目的とする。 An object of the present disclosure is to provide a repainting method capable of improving the appearance quality after repainting of existing building materials, a drilling tool used in the repainting method, and a building provided with a new coating film by the repainting method. And
本開示の再塗装方法は、既設の建材の旧塗装膜の上から再塗装する再塗装方法であって、
前記旧塗装膜に複数の孔を穿設した後に、前記旧塗装膜の上塗り塗装を行って新塗装膜を形成することを特徴とする再塗装方法とした。
The repainting method of the present disclosure is a repainting method in which repainting is performed on the old paint film of an existing building material,
A re-coating method is characterized in that after forming a plurality of holes in the old paint film, a new paint film is formed by performing an overcoating of the old paint film.
なお、前記建材が金属材料であってもよい。
また、前記上塗り塗装に用いる塗料が透湿性を有することが好ましい。
また、前記旧塗装膜に複数の孔を開ける際に、複数の針が突設された孔開け具を用いて、前記複数の針を前記旧塗装膜に突き刺して前記孔を穿設することが好ましい。
The building material may be a metal material.
Moreover, it is preferable that the coating material used for the said top coat has moisture permeability.
Further, when a plurality of holes are formed in the old paint film, the holes may be formed by piercing the old paint film with the plurality of needles using a hole punching tool provided with a plurality of needles. preferable.
そして、本発明の孔開け具は、把持部と、前記把持部に回転可能に支持された円筒状の回転体と、前記回転体の外周から外径方向に突設された複数の針と、を備えることを特徴とする孔開け具とした。
また、本発明の建物は、建物外表面を形成する建材が、上記再塗装方法により旧塗装膜の上に上塗り塗装された新塗装膜を備えることを特徴とする建物とした。
And the drilling tool of the present invention includes a gripping part, a cylindrical rotating body rotatably supported by the gripping part, and a plurality of needles protruding in an outer diameter direction from the outer periphery of the rotating body, It was set as the drilling tool characterized by providing.
Moreover, the building of the present invention is a building characterized in that the building material forming the outer surface of the building includes a new coating film that is overcoated on the old coating film by the above repainting method.
本開示の再塗装方法による再塗装を行った建材では、旧塗装膜の下に生じた空隙内の空気および水分が膨張した場合、その空気および気化した水分（水蒸気）は、旧塗膜部分では孔を通過することができる。したがって、旧塗装膜の上に新塗装膜を重ねた場合に、両塗装膜の全厚み分を空気および水蒸気が通過するのと比較して、空気および水蒸気の通過が容易となり、新塗装面が膨らむのを抑制することができる。よって、再塗装後の外観品質を向上できる。 In building materials that have been repainted by the repainting method of the present disclosure, when the air and moisture in the voids created under the old paint film expand, the air and vaporized water (water vapor) Can pass through the hole. Therefore, when the new coating film is layered on the old coating film, the passage of air and water vapor becomes easier compared to the case where air and water vapor pass through the entire thickness of both coating films. Swelling can be suppressed. Therefore, the appearance quality after repainting can be improved.
また、建材が金属材料である場合、日射などにより建材が高温になり易く、上記の空隙内の空気および水分の膨張が生じやすいため、上記の新塗装面の膨らみ抑制効果およびそれによる外観品質の向上効果がより顕著となる。
また、上塗り塗装に用いる塗料として透湿性を有する塗料を用いた場合、上記の空隙内の空気および水蒸気が新塗装膜を通過しやすく、新塗装面の膨らみ抑制効果およびそれによる外観品質の向上効果を確実に得ることができる。
また、旧塗装膜に複数の孔を開ける際に、孔開け具を用いた場合、複数の孔を同時に設けることができ、孔開け作業性に優れる。
In addition, when the building material is a metal material, the building material is likely to become hot due to solar radiation, etc., and the expansion of air and moisture in the gap is likely to occur. The improvement effect becomes more remarkable.
In addition, when a paint with moisture permeability is used as the paint used for the top coat, the air and water vapor in the above gap easily pass through the new paint film, and the effect of suppressing the swelling of the new paint surface and the effect of improving the appearance quality thereby Can be definitely obtained.
Moreover, when using a drilling tool when making a several hole in an old coating film, a several hole can be provided simultaneously and it is excellent in drilling workability | operativity.
そして、本発明の孔開け具は、把持部を把持し、旧塗装膜に沿って回転体を転がしながら移動させるだけで、旧塗装膜に複数の孔を開けることができ、作業性に優れる。

Moreover, the building of this invention can improve the external appearance quality after repainting of the building material which forms a building outer surface.
以下、本開示の再塗装方法を実施するための形態を、図面に基づいて説明する。
（実施の形態１）
以下に、図面に基づいて実施の形態１の再塗装方法、この再塗装方法に用いる孔開け具、この再塗装方法により再塗装を行ったユニット建物について説明する。
Hereinafter, the form for implementing the repainting method of this indication is demonstrated based on drawing.
(Embodiment 1)
Hereinafter, the repainting method of the first embodiment, the drilling tool used in this repainting method, and the unit building that has been repainted by this repainting method will be described based on the drawings.
図１は、実施の形態１の再塗装方法により再塗装を行う対象である既設の建材としての外壁材１０を示す断面図である。
この外壁材１０は、本実施の形態１では、金属材料（例えば、アルミ）により形成されたものである。
FIG. 1 is a cross-sectional view showing an outer wall material 10 as an existing building material that is a target to be repainted by the repainting method of the first embodiment.
In the first embodiment, the outer wall material 10 is formed of a metal material (for example, aluminum).
また、外壁材１０は、ユニット建物に用いられたもので、このユニット建物を構築する建物ユニットの製造時に、工場において塗装された工場塗装膜３０により覆われている。この工場塗装膜３０は、スタッコ玉吹塗装により形成されたもので、骨材２１を有した下塗層２０に工場塗装膜３０を上塗りして形成されている。なお、骨材２１としては、大理石、砂などを用いることができる。 The outer wall material 10 is used for a unit building, and is covered with a factory coating film 30 that is painted in a factory when the building unit that constructs the unit building is manufactured. This factory coating film 30 is formed by stucco ball blowing coating, and is formed by overcoating the factory coating film 30 on the undercoat layer 20 having the aggregate 21. As the aggregate 21, marble, sand, or the like can be used.
さらに、既設の外壁材１０は、ユニット建物の建築後、再塗装が一度成されており、工場塗装膜３０の上に再塗装膜４０が設けられている。
なお、この再塗装膜４０および工場塗装膜３０には、透湿性を有した塗料が用いられている。このような透湿性を有した塗料として、例えば、シリコン系、フッ素系、ポリアミド系、アクリル系のポリウレタン系の塗料が用いることができる。具体的には、特許文献２に記載された塗料や特開昭６３−４３９７６号公報、特開平１−２８１１８０号公報、特開平２−１５０４７５号公報、特開平１０−１１０１３６号公報、特開平１１−９２７０８号公報、特開２００２−２２６７６３号公報、特開２００２−３３２４２５号公報に記載された塗料などを用いることができるが、これに限定されるものではない。
Furthermore, the existing outer wall material 10 is repainted once after the building of the unit building, and the repainted film 40 is provided on the factory painted film 30.
The repaint film 40 and the factory paint film 30 are made of a paint having moisture permeability. As such a paint having moisture permeability, for example, a silicon-based, fluorine-based, polyamide-based, or acrylic polyurethane-based paint can be used. Specifically, the paints described in Patent Document 2, JP-A-63-43976, JP-A-1-281180, JP-A-2-150475, JP-A-10-110136, JP-A-11 Although the paint etc. which were described in -92708 gazette, Unexamined-Japanese-Patent No. 2002-226863, and Unexamined-Japanese-Patent No. 2002-332425 can be used, it is not limited to this.
また、上述のスタッコ玉吹塗装により形成された工場塗装膜３０には、骨材２１による凹凸形状により空隙１００が生じている。
この空隙１００は、空気の他に寒暖差による結露により内部に水分を含む。そして、この空隙１００が、日射を受けるなどして高温になると、空隙１００の空気および水分が膨張する場合がある。
Further, in the factory coating film 30 formed by the above-described stucco ball blowing coating, a void 100 is generated due to the uneven shape by the aggregate 21.
The air gap 100 contains moisture in addition to air due to condensation due to temperature difference. And when this space | gap 100 becomes high temperature by receiving a solar radiation etc., the air and water | moisture content of the space | gap 100 may expand | swell.
この場合、工場塗装膜３０および再塗装膜４０は、透湿性、通気性を有するため、膨張した空気および水分は、水蒸気１１０となって、図１において矢印に示すように、外気中に放出される。したがって、塗装膜強度が空隙１００の膨れ強度を上回る関係（塗装膜強度＞膨れ強度）となっており、両塗装膜３０，４０は、大きな膨れや破損が生じることは無い。なお、外壁材１０として金属材料のものを用いているため、空隙１００は、より高温になり易く、その内部の空気および水分は、より膨張しやすい。 In this case, since the factory coating film 30 and the repainting film 40 have moisture permeability and air permeability, the expanded air and moisture become water vapor 110 and are released into the outside air as indicated by arrows in FIG. The Therefore, the coating film strength exceeds the swelling strength of the gap 100 (coating film strength> swelling strength), and the coating films 30 and 40 are not greatly swollen or damaged. In addition, since the thing of a metal material is used as the outer wall material 10, the space | gap 100 tends to become high temperature, and the air and water | moisture content inside the air | atmosphere tend to expand more easily.
次に、上記の図１に示す既設の建材としての外壁材１０を、実施の形態１による再塗装方法により２回目以降の再塗装を行う手順について説明する。
この再塗装方法では、塗装を行う前に孔開け工程を実施する。
図２は、孔開け工程の実施後の既設の建材である外壁材１０（塗装対象）を示す断面図である。孔開け工程では、少なくとも、再塗装膜４０に複数の孔４１を貫通して形成する。この場合、孔４１は、工場塗装膜３０に達するように開けてもよいし、あるいは、再塗装膜４０を完全に貫通しない場合でも、後述の効果を得ることは可能である。
Next, a procedure for repainting the outer wall material 10 as the existing building material shown in FIG. 1 by the second and subsequent repainting methods according to the first embodiment will be described.
In this repainting method, a drilling step is performed before painting.
FIG. 2 is a cross-sectional view showing the outer wall material 10 (coating object) that is an existing building material after the drilling step. In the drilling step, at least the plurality of holes 41 are formed through the repaint film 40. In this case, the hole 41 may be opened so as to reach the factory coating film 30, or even if the hole 41 does not completely penetrate the repainting film 40, the effects described later can be obtained.
ここで、この孔開け工程に用いる孔開け具２００を図４Ａ、図４Ｂに基づいて説明する。
この孔開け具２００は、把持部２１０と、ローラ（回転体）２２０と、針２２１とを備える。
把持部２１０は、把持パイプ２１１と、ローラ支持部２１２とを備える。
把持パイプ２１１は、把持しやすい太さの金属製あるいは樹脂製のパイプである。
Here, the drilling tool 200 used for this drilling process is demonstrated based on FIG. 4A and FIG. 4B.
The punching tool 200 includes a grip portion 210, a roller (rotating body) 220, and a needle 221.
The grip portion 210 includes a grip pipe 211 and a roller support portion 212.
The gripping pipe 211 is a metal or resin pipe having a thickness that is easy to grip.
ローラ支持部２１２は、図示のように一対の支持片２１２ａ，２１２ａと、この一対の支持片２１２ａ，２１２ａを、離間して対面した状態に支持する支持部２１２ｂと、により略逆Ｕ字状に形成されている。
そして、把持パイプ２１１は、支持部２１２ｂから略直角に起立状態でその一端が支持部２１２ｂに結合されている。
As shown in the figure, the roller support portion 212 is formed in a substantially inverted U shape by a pair of support pieces 212a and 212a and a support portion 212b that supports the pair of support pieces 212a and 212a so as to face each other apart. Is formed.
The grip pipe 211 is erected at a substantially right angle from the support portion 212b and one end thereof is coupled to the support portion 212b.
ローラ２２０は、円筒状に形成され、軸方向の両端部が蓋材２２２により塞がれている。そして、両端の蓋材２２２が、ローラ支持軸２１３を中心に回転可能に一対の支持片２１２ａ，２１２ａに支持されている。 The roller 220 is formed in a cylindrical shape, and both end portions in the axial direction are closed by a lid member 222. The lid members 222 at both ends are supported by the pair of support pieces 212a and 212a so as to be rotatable about the roller support shaft 213.
針２２１は、例えば、鉄やステンレスなどの金属製のものを用いることができ、本実施の形態１では、一般構造用圧延鋼材（ＳＳ）のものを用いている。また、針２２１は、ローラ２２０の外周から外径方向に突出され、先端がとがった形状に形成されたもので、全体長さ５〜３０ｍｍ、半径０．５〜３ｍｍ程度の範囲の大きさで、軸方向に沿って一定間隔で複数設けられ、かつ、周方向に複数列設けられている。さらに、針２２１は、図示のように、隣り合う列では、軸方向に沿う方向の位置を異ならせて、周方向に互い違いに配置されている。 The needle 221 can be made of, for example, a metal such as iron or stainless steel, and in the first embodiment, a general structural rolled steel (SS) is used. The needle 221 protrudes from the outer periphery of the roller 220 in the outer diameter direction and is formed in a shape with a sharp tip, and has a total length of 5 to 30 mm and a radius of about 0.5 to 3 mm. A plurality are provided at regular intervals along the axial direction, and a plurality of rows are provided in the circumferential direction. Furthermore, as shown in the figure, the needles 221 are alternately arranged in the circumferential direction in adjacent rows with different positions in the axial direction.
また、本実施の形態１では、針２２１として、円柱状の根本部２２１ａの先端面から円錐部２２１ｂを立ち上げた形状のものを用いている。根本部２２１ａは、長さ０〜１０ｍｍ程度、半径１〜３ｍｍ程度の範囲の大きさに形成されている。なお、長さ０とは、根本部２２１ａを形成しないものも含むことを意味する。
また、円錐部２２１ｂは、長さ５〜３０ｍｍ程度、半径０．５〜２ｍｍ程度の大きさに形成されている。
In the first embodiment, the needle 221 has a shape in which the conical portion 221b is raised from the tip surface of the columnar root portion 221a. The root portion 221a is formed in a size in a range of about 0 to 10 mm in length and about 1 to 3 mm in radius. In addition, the length 0 means that what does not form the root part 221a is included.
Further, the conical portion 221b is formed to have a length of about 5 to 30 mm and a radius of about 0.5 to 2 mm.
なお、ローラ２２０は、例えば、直径３０〜１００ｍｍ程度、幅１００〜２００ｍｍ程度の範囲のものを用いるのが好ましい。また、針２２１は、例えば、１００〜５００本程度設けるのが好ましい。 For example, it is preferable to use a roller 220 having a diameter of about 30 to 100 mm and a width of about 100 to 200 mm. Moreover, it is preferable to provide about 100 to 500 needles 221, for example.

具体的には、作業者は、把持部２１０の把持パイプ２１１を握って、ローラ２２０を、再塗装膜４０に沿って転動させる。これにより、針２２１が、再塗装膜４０に対して略直角に突き刺さり、再塗装膜４０を貫通する孔４１を複数形成することができる。
As described above, in the hole making step, the hole 41 penetrating the repaint film 40 is opened using the hole making tool 200 shown in FIGS. 4A and 4B.
Specifically, the operator grasps the grip pipe 211 of the grip portion 210 and rolls the roller 220 along the repaint film 40. Thereby, the needle 221 can be pierced at a substantially right angle with respect to the repaint film 40 and a plurality of holes 41 penetrating the repaint film 40 can be formed.

The new coating film 50 also uses a paint having moisture permeability. Further, as the paint, the above-described silicon-based or fluorine-based paint can be used.
（実施の形態１の作用）
次、実施の形態１の作用を説明する。
実施の形態１の作用の説明する前に、図５に基づいて、孔開け工程を実施せずに再塗装膜４０の上から新塗装膜５０を形成した場合について説明する。
(Operation of Embodiment 1)
Next, the operation of the first embodiment will be described.
Before explaining the operation of the first embodiment, a case where a new coating film 50 is formed on the re-coating film 40 without performing the hole forming step will be described based on FIG.
図１に基づいて説明したように、工場塗装膜３０の下に、空隙１００（図１参照）が生じた場合、外壁材１０が日射などにより高温になると、空隙１００内の空気や水分が膨張する。特に、外壁材１０が金属である場合、より高温になり易く、このような空隙１００内の空気、水分の膨張が生じやすい。 As described with reference to FIG. 1, when the void 100 (see FIG. 1) is generated under the factory coating film 30, the air and moisture in the void 100 expand when the outer wall material 10 becomes hot due to solar radiation or the like. To do. In particular, when the outer wall material 10 is a metal, the temperature tends to be higher, and the expansion of air and moisture in the gap 100 is likely to occur.
このように、空隙１００の空気や水分が膨張した際に、図５に示すように、塗膜が、工場塗装膜３０、再塗装膜４０、新塗装膜５０と重なってその厚みが増すと、各塗装膜３０，４０，５０のそれぞれが透湿性を有していても、全体での透湿性および通気性が低下する。
このため、図５に示すように、空隙１００内が膨張した際に空気や水蒸気１１０がこの三重の各塗装膜３０，４０，５０を通過できず、外部に放出されない。このため、各塗装膜３０，４０，５０の下に、図５に示すような空気溜まり１２０が生じ、工場塗装膜３０、再塗装膜４０、新塗装膜５０が膨れ上がる現象が生じ、外観品質が低下する。また、このとき、膨れ強度が塗装膜強度を上回ると（塗装膜強度＜膨れ強度）、工場塗装膜３０、再塗装膜４０、新塗装膜５０が破損するおそれもある。
Thus, when the air and moisture in the gap 100 are expanded, as shown in FIG. 5, when the coating film overlaps with the factory coating film 30, the repainting film 40, and the new coating film 50, the thickness thereof increases. Even if each of the coating films 30, 40, 50 has moisture permeability, the overall moisture permeability and air permeability are reduced.
For this reason, as shown in FIG. 5, when the inside of the space | gap 100 expand | swells, air and the water vapor | steam 110 cannot pass through each of these triple coating films 30,40,50, and are not discharge | released outside. Therefore, an air reservoir 120 as shown in FIG. 5 is generated under each of the coating films 30, 40, 50, and a phenomenon in which the factory coating film 30, the repainting film 40, and the new coating film 50 are swollen occurs, and the appearance quality is increased. Decreases. At this time, if the swelling strength exceeds the coating film strength (coating film strength <blowing strength), the factory coating film 30, the repainting film 40, and the new coating film 50 may be damaged.
それに対し、本実施の形態１では、図３に示すように、空隙１００の内部の空気や水分が膨張した場合、その空気や水蒸気１１０は、再塗装膜４０の孔４１を通って容易に通過し、新塗装膜５０の透湿性に基づいて新塗装膜５０を通過して外部に放出される。
すなわち、工場塗装膜３０、再塗装膜４０、新塗装膜５０における通気性、透湿性としては、工場塗装膜３０および新塗装膜５０をそれぞれ通過可能な透湿性、通気性を有していればよい。このため、図５に示すように、三層の各塗装膜３０，４０，５０が直接に重なったものと比較して、空隙１００内の空気および水分を容易に外部に放出することができる。
したがって、塗膜の膨れ上がり現象や破損が生じるのを抑制して、高い外観品質を維持することができる。
On the other hand, in the first embodiment, as shown in FIG. 3, when air or moisture inside the gap 100 expands, the air or water vapor 110 easily passes through the hole 41 of the repaint film 40. Then, based on the moisture permeability of the new coating film 50, it passes through the new coating film 50 and is released to the outside.
That is, as the air permeability and moisture permeability in the factory coating film 30, the repaint film 40, and the new coating film 50, as long as they have moisture permeability and air permeability that can pass through the factory coating film 30 and the new coating film 50, respectively. Good. For this reason, as shown in FIG. 5, the air and water | moisture content in the space | gap 100 can be discharge | released outside easily compared with what each three-layer coating film 30,40,50 directly overlapped.
Accordingly, it is possible to maintain the high appearance quality by suppressing the swelling phenomenon and damage of the coating film.
（実施の形態１の効果）
以下に、実施の形態１の再塗装方法の効果を列挙する。
１）実施の形態１の再塗装方法は、
既設の建材としての外壁材１０の旧塗装膜としての工場塗装膜３０、再塗装膜４０の上から再塗装する再塗装方法であって、
旧塗装膜の少なくとも再塗装膜４０に複数の孔４１を穿設した後に、工場塗装膜３０、再塗装膜４０の上から上塗り塗装を行って新塗装膜５０を形成することを特徴とする。
したがって、旧塗装膜としての工場塗装膜３０、再塗装膜４０の下の空隙１００部分内の空気および水分が膨張した場合、その膨脹空気および膨張水蒸気は、再塗装膜４０の部分では孔４１を通過することができる。よって、膨張空気および膨張水蒸気により新塗装膜５０が膨らむのを抑制することができ、再塗装後の外観品質を向上できる。
(Effect of Embodiment 1)
The effects of the repainting method according to Embodiment 1 are listed below.
