Description
本発明は、水系塗料組成物および壁面化粧方法に関する。さらに詳しくは、古壁の補修に用いられ、とくに塗り壁などに代表される多孔質素材を利用した吸放湿性能を有する内装用の壁面を化粧するのに用いられる水系塗料組成物および壁面化粧方法に関する。 The present invention relates to a water-based coating composition and a wall surface decorative method. More specifically, the water-based coating composition and wall surface makeup used for repairing old walls, especially for making interior wall surfaces having moisture absorption and desorption performance using porous materials such as painted walls. Regarding the method.
けいそう土などに代表される多孔質素材を利用した内装仕上材を塗った壁は、表面の細やかな凹凸が和風伝統の風合いを持った壁として好まれている。また、けいそう土、ゼオライトおよび蛭石などに代表される多孔質素材を含有させて吸放湿性をもたせたことにより、居住空間の快適性を確保できるものである。しかるに、これらの内装壁も長年使用する間に、壁面の汚れやアクやシミ（いずれも経年的に壁面に滲み出る汚れ）が発現することがあるが、これらは美感を低下させるので、化粧して綺麗な壁にしたいという要望がある。 Walls with interior finishes made of porous materials such as diatomaceous earth are preferred as the walls with fine texture on the surface and traditional Japanese texture. Moreover, the comfort of the living space can be ensured by incorporating a porous material typified by diatomaceous earth, zeolite, and meteorite to impart moisture absorption and desorption. However, while these interior walls have been used for many years, stains on the walls, axes and stains (both stains that ooze out on the walls over time) may appear, but these deteriorate the aesthetics, so make up There is a desire to make a beautiful wall.
従来より存在する古壁の化粧は、つぎのようにして行われていた。
内装壁の表面に、リフォームとして塗装を行う場合、アクシミ止めとして、通常アクリル系樹脂などによるシーラー処理が必要であり、シーラー処理を行うと塗り壁表面の吸放湿性能を著しく低下させてしまう。またシーラー処理をしない場合でも、市販のペンキ等で塗装を行うと多量の着色顔料や樹脂によるコーティングによって、塗り壁の吸放湿性や意匠性を損なうことになり、必ずしも満足し得るものは今までなかった。
Conventional makeup of old walls has been performed as follows.
When coating the surface of the interior wall as a renovation, a sealer treatment with an acrylic resin or the like is usually required to prevent a stain, and if the sealer treatment is performed, the moisture absorption / release performance of the painted wall surface is significantly reduced. Even without a sealer treatment, coating with commercially available paints, etc., may damage the moisture absorption and design of painted walls due to the coating with a large amount of color pigments and resins, and the ones that are always satisfactory can be satisfied. There wasn't.
内装用塗料としては、種々の従来技術文献が存在しており、特許文献１のそれらの一つである。しかし、この特許文献１は、最初に内装壁を構成するための塗料組成物であり、古壁の吸湿性能を損うことなく、古壁を美麗に装飾する等の性能を意図したものではない。また、長期間かけて発現するアクやシミを隠蔽する等の性能も当然に意図したものではなく、そのような効果を発揮することもできないものである。 There are various prior art documents as interior paints, and one of them is Patent Document 1. However, this patent document 1 is a coating composition for constituting an interior wall first, and does not intend performance such as beautiful decoration of the old wall without impairing the moisture absorption performance of the old wall. . Moreover, the performance of concealing the spots and stains that develop over a long period of time is not intended as a matter of course, and such an effect cannot be exhibited.
本発明は、上記事情に鑑み、古壁がもつ吸放湿性を損なうことなく化粧することができる水系塗料組成物および壁面化粧方法を提供することを目的とする。
また、古壁から染み出したアクやシミを隠蔽できる水系塗料組成物および壁面化粧方法を提供することを目的とする。さらに、古壁に対し新たに美的外観を付与するよう装飾できる水系塗料組成物および壁面化粧方法を提供することを目的とする。
In view of the above circumstances, an object of the present invention is to provide a water-based paint composition and a wall surface makeup method that can make up without impairing the moisture absorption and desorption properties of old walls.
It is another object of the present invention to provide a water-based paint composition and a wall surface decorative method capable of concealing scum and spots that have exuded from old walls. It is another object of the present invention to provide a water-based paint composition and a wall surface decorative method that can be decorated to give a new aesthetic appearance to an old wall.
本発明者らは、上記事情に鑑み鋭意検討を重ねた結果、無機質粉体を配合すると共に、樹脂固形分４０〜６０重量％カチオン型アクリル系エマルション樹脂と樹脂固形分４０〜６０重量％カチオン型酢酸ビニル系エマルション樹脂を３：７〜７：３の割合で配合したバインダーを１０〜３０重量％配合した水系塗料組成物とすることにより、該水系塗料組成物をローラーや刷毛等を用いて壁面に塗布することによって目的を達成しうることを認め、本発明を完成するに至った。
エマルション樹脂によるバインダーの造膜過程の際、アクリルエマルション粒子と酢酸ビニルエマルション粒子が混在することにより、アクリル/酢酸ビニル樹脂のハイブリッドの塗膜が形成され、アクリル樹脂が有する耐候性、耐水性を維持すると共に、酢酸ビニル樹脂が有する透湿性を維持することができた。
また古壁に対するアクシミ止め対策として、カチオン型凝集剤を配合することにより、塗布作業性を低下することなく、アクシミ止め効果を発揮することができる。
As a result of intensive studies in view of the above circumstances, the present inventors have blended inorganic powder, and have a resin solid content of 40 to 60 wt% cationic acrylic emulsion resin and a resin solid content of 40 to 60 wt% cationic type. By using a water-based coating composition containing 10 to 30% by weight of a binder in which a vinyl acetate emulsion resin is blended at a ratio of 3: 7 to 7: 3, a wall surface is used for the water-based coating composition using a roller or a brush. It was recognized that the object could be achieved by applying the coating to the present invention, and the present invention was completed.
During the process of forming a binder with an emulsion resin, acrylic and vinyl acetate emulsion particles are formed by mixing acrylic emulsion particles and vinyl acetate emulsion particles, maintaining the weather resistance and water resistance of the acrylic resin. At the same time, the moisture permeability of the vinyl acetate resin could be maintained.
In addition, as a countermeasure against a stain on the old wall, the effect of aching can be exhibited without deteriorating the coating workability by adding a cationic flocculant.
本発明の水系塗料組成物によれば、塗り壁に代表される多孔質素材を利用した吸放湿性能の高い壁面に対し、その壁面がもつ吸放湿性能を損なうことなく壁面表面を水系塗料によって装飾する事ができる。 According to the water-based paint composition of the present invention, the wall surface is coated with water-based paint without impairing the moisture absorption / release performance of the wall surface with respect to the wall surface having high moisture absorption / release performance using a porous material typified by a painted wall. Can be decorated.
（本発明の技術原理）
本発明で用いるカチオン型アクリル系エマルション樹脂は、耐水性を有し強靭な膜を形成する性質があり、カチオン型酢酸ビニル系エマルション樹脂は、親水性を有し水蒸気分子の拡散移動が可能で吸放湿性を阻害しない性質を有している。
図１に基づき、本発明の技術原理を説明する。Ａは本発明の塗料組成物であり、Ｂは比較例として示した一般的な塗料組成物である。Ｉは乳化状態を示し、ＩＩは塗布後に水分が蒸発していく状態を示し、ＩＩＩは塗料が硬化し成膜できた状態を示している。
乳化状態Ｉでは、本発明の塗料でもアクリル系樹脂の粒子と酢酸ビニル樹脂の粒子は分散しており、一般的塗料Ｂと同様である。しかし、塗布後に段々と水分が蒸発していく状態ＩＩでは、アクリル系樹脂粒子同士が結合し、また酢酸ビニル系樹脂粒子同士が結合する。そして、塗膜組成物が融着し成膜された状態ＩＩＩでは、酢酸ビニル樹脂粒子が互いに結合して作られた部分が水蒸気分子通路となって、透湿性を発揮することとなる。一般塗料が全く水蒸気通路を有しないのと比べると、透湿効果が高くなることが明らかである。
このような水蒸気通路の形成は、耐水性を有する樹脂（アクリル系）と親水性を有する樹脂（酢酸ビニル系）の２種類の性質の異なる樹脂を用いて塗膜を形成したことにより可能となったものである。また、本発明では、塗膜自身がアクリル系樹脂で形成された強靭な膜を有するので、塗膜自体による封じ込めも可能である。さらに、塗料組成物にカチオン形凝集剤を配合したときは、アクやシミの成分が凝集剤に吸着され、塗膜表面にアクやシミがでることはないので、アクシミ防止効果を発揮できる。
なお、カチオン型凝集剤を非カチオン型エマルションに添加すると、水系塗料組成物が不安定な状態となり、瞬時のゲル化や貯蔵時のゲル化により変質し、塗布作業に支障を来す他、アクシミの防止、吸放湿性能、下地表面の凹凸への追従性が失われる。しかし、カチオン型エマルションに添加するなら、そのような不都合はなく、アクシミ防止効果のみを発揮することができる。本発明はこのような性質も利用したものである。
(Technical principle of the present invention)
The cationic acrylic emulsion resin used in the present invention has the property of forming a tough film with water resistance, and the cationic vinyl acetate emulsion resin is hydrophilic and can diffuse and move water vapor molecules. It has the property of not inhibiting moisture release.
The technical principle of the present invention will be described with reference to FIG. A is a coating composition of the present invention, and B is a general coating composition shown as a comparative example. I indicates an emulsified state, II indicates a state in which moisture evaporates after application, and III indicates a state in which the coating is cured and a film can be formed.
In the emulsified state I, the acrylic resin particles and the vinyl acetate resin particles are dispersed in the paint of the present invention, and the same as in the general paint B. However, in the state II in which moisture gradually evaporates after application, acrylic resin particles are bonded together, and vinyl acetate resin particles are bonded together. In the state III where the coating composition is fused and formed into a film, a portion formed by bonding the vinyl acetate resin particles to each other becomes a water vapor molecular passage and exhibits moisture permeability. It is clear that the moisture permeable effect is higher than that of the general paint having no water vapor passage.
Such a water vapor passage can be formed by forming a coating film using a resin having two different properties, a water-resistant resin (acrylic type) and a hydrophilic resin (vinyl acetate type). It is a thing. Moreover, in this invention, since the coating film itself has a tough film | membrane formed with the acrylic resin, the containment by the coating film itself is also possible. Further, when a cationic flocculant is blended in the coating composition, the components of axes and stains are adsorbed by the aggregating agent, and no axes or stains are formed on the surface of the coating film.
In addition, when a cationic flocculant is added to a non-cationic emulsion, the water-based coating composition becomes unstable and changes in quality due to instantaneous gelation or gelation during storage, which may hinder the application work. Prevention, moisture absorption / release performance, and followability to irregularities on the underlying surface are lost. However, if added to the cationic emulsion, there is no such inconvenience, and only an axime prevention effect can be exhibited. The present invention also utilizes such properties.
本発明の水系塗料組成物に使用されるバインダーは、カチオン型アクリル系エマルション樹脂（アクリル酸エステル、アクリルスチレン共重合体、アクリル樹脂エチレン酢酸ビニル共重合体など）とカチオン型酢酸ビニル系エマルション樹脂（エチレン酢酸ビニル共重合体、酢ビ塩化ビニル共重合体、酢酸ビニルベオバ共重合体など）を配合した合成樹脂エマルションである。 The binder used in the water-based coating composition of the present invention includes a cationic acrylic emulsion resin (such as an acrylate ester, an acrylic styrene copolymer, an acrylic resin ethylene vinyl acetate copolymer) and a cationic vinyl acetate emulsion resin ( A synthetic resin emulsion containing an ethylene vinyl acetate copolymer, a vinyl acetate vinyl chloride copolymer, a vinyl acetate beoba copolymer, and the like.
本発明の塗料組成物は古壁の化粧が主たる用途である。古壁の化粧に用いる場合、下地となる塗り壁（古壁）に対する塗料の接着を良くするためには、この合成樹脂エマルションの下地への染み込みが重要となる。樹脂の粘度が著しく高い場合や樹脂量が極端に多い場合は、下地に染み込み難く不適である。
また、接着強度の問題だけでなく、染み込みによる下地表面の凹凸への追従性が無い場合、下地の塗り壁がもつ独特な風合いを失ってしまう。しかしながら、粘度が著しく低い場合や樹脂量が少ない場合、今度は塗材の垂れや顔料の剥がれ、風化により強度不足が生じる。
本発明では、これらの点をつぎに記述するように、アクリル系樹脂と酢酸ビニル系樹脂の配合割合を工夫することで解決している。
The coating composition of the present invention is mainly used for makeup of old walls. When used for makeup of old walls, in order to improve the adhesion of the paint to the painted wall (old wall) as the base, it is important to soak the synthetic resin emulsion into the base. When the viscosity of the resin is remarkably high or the amount of the resin is extremely large, it is not suitable because it does not easily penetrate into the base.
In addition to the problem of adhesive strength, if there is no followability to the unevenness of the underlying surface due to soaking, the unique texture of the underlying coating wall is lost. However, when the viscosity is remarkably low or the amount of resin is small, this time, the coating material droops, the pigment peels off, and weathering causes insufficient strength.
In the present invention, these points are solved by devising the blending ratio of the acrylic resin and the vinyl acetate resin as described below.
カチオン型アクリル系エマルション樹脂とカチオン型酢酸ビニル系エマルション樹脂の配合割合は３〜７：７〜３の範囲に調整する。カチオン型酢酸ビニル系エマルション樹脂の割合がこの範囲を下回ると、樹脂膜の透湿性を低下させてしまい、カチオン型酢酸ビニル系エマルション樹脂の割合がこの範囲を上回ると樹脂膜の耐水性や光沢性を低下させることとなる。一方、カチオン型アクリル系エマルション樹脂の割合がこの範囲を下回ると、耐水性や光沢性を低下させてしまい、カチオン型アクリル系エマルション樹脂の割合がこの範囲を上回ると樹脂膜の透湿性を低下させることとなる。上記配合割合であると、透湿性を維持でき、かつ耐水性や光沢性も保持できる。 The blending ratio of the cationic acrylic emulsion resin and the cationic vinyl acetate emulsion resin is adjusted to a range of 3-7: 7-3. If the proportion of the cationic vinyl acetate emulsion resin is below this range, the moisture permeability of the resin film will be reduced. If the proportion of the cationic vinyl acetate emulsion resin is above this range, the water resistance and glossiness of the resin film will be reduced. Will be reduced. On the other hand, if the proportion of the cationic acrylic emulsion resin is below this range, the water resistance and gloss will be reduced, and if the proportion of the cationic acrylic emulsion resin exceeds this range, the moisture permeability of the resin film will be reduced. It will be. If it is the above blending ratio, moisture permeability can be maintained, and water resistance and gloss can be maintained.
上記配合割合のバインダー各樹脂に対しては、樹脂固形物割合は、下記のようにすることが好ましい。
すなわち、バインダーとして用いるカチオン型アクリル系エマルション樹脂固形分の割合は、４０〜６０重量％の範囲が好ましい。４０重量％を下回ると、液ダレにより壁面に充分な塗膜が形成されない。６０重量％を上回ると粘度が高くなり、塗料の伸びが悪く作業性が低下する。
さらに、バインダーとして用いるカチオン型酢酸ビニル系エマルション樹脂の樹脂固形分の割合は４０〜６０重量％の範囲が好ましい。４０重量％を下回ると、液ダレにより壁面に充分な塗膜が形成されない。６０重量％を上回ると粘度が高くなり、塗料の伸びが悪く作業性が低下する。
It is preferable that the resin solid ratio is as follows for each resin of the above-mentioned blending ratio.
That is, the ratio of the solid content of the cationic acrylic emulsion resin used as the binder is preferably in the range of 40 to 60% by weight. When it is less than 40% by weight, a sufficient coating film is not formed on the wall surface due to liquid dripping. If it exceeds 60% by weight, the viscosity will be high, and the paint will be poorly stretched and workability will be lowered.
Furthermore, the ratio of the resin solid content of the cationic vinyl acetate emulsion resin used as the binder is preferably in the range of 40 to 60% by weight. When it is less than 40% by weight, a sufficient coating film is not formed on the wall surface due to liquid dripping. If it exceeds 60% by weight, the viscosity will be high, and the paint will be poorly stretched and workability will be lowered.
バインダーとして配合する無機質粉体は、炭酸カルシウム、雲母石、珪藻土、カオリン、クレー、タルク、シリカ粉、蝋石等の粉体が用いられる。
無機質粉体の粒径は６０μｍ以下に調整すべきである。粒径が６０μｍを超えると、塗布したときに多孔質素材壁面の質感を損なうこととなる。さらに、無機質粉体は５〜２５重量％（水系塗料組成物１００重量部に対し）の割合で配合すべきであり、５重量％を下回ると塗装したときの下地の隠蔽率を低下させてしまい、２５重量％を上回ると多孔質素材壁面の質感を損なうこととなる。前記配合割合であると、けいそう土を含む既存塗装膜の微少凹凸を活かす質感保持も可能である。
As the inorganic powder to be blended as the binder, powders such as calcium carbonate, mica stone, diatomaceous earth, kaolin, clay, talc, silica powder and wax stone are used.
The particle size of the inorganic powder should be adjusted to 60 μm or less. When the particle diameter exceeds 60 μm, the texture of the porous material wall surface is impaired when applied. Furthermore, the inorganic powder should be blended at a ratio of 5 to 25% by weight (with respect to 100 parts by weight of the water-based coating composition), and if it is less than 5% by weight, the concealment rate of the base when coated is reduced. If it exceeds 25% by weight, the texture of the porous material wall surface will be impaired. When the blending ratio is used, it is possible to maintain a texture that makes use of minute irregularities of an existing coating film containing diatomaceous earth.
本発明の塗料組成物に凝集剤を配合する場合は、カチオン型凝集剤を１〜１０重量％（水系塗料組成物１００重量部に対し）の割合で配合する。１重量％を下回ると下地のアクシミ止め効果が十分に発揮されず、１０重量％を上回るとアクシミ止め効果は高まるが、塗料がゲル状となって塗装作業性を低下させ、また塗料の長期的な貯蔵安定性が低下する。前記配合割合であると、アクシミ止めの効果が充分であり、かつ塗装作業性が良く貯蔵安定性も良好に維持できる。
カチオン型凝集剤の代表的なものとしては、ジシアンジアミド・ポリアルキレンポリアミン重縮合物、酢酸亜鉛、酢酸アルミニウム等が挙げられる。カチオン型以外の凝集剤（アニオン系凝集剤）を添加した場合、カチオン型アクリル系エマルション樹脂とカチオン型酢酸ビニル系エマルション樹脂をバインダー樹脂として使用していることから、ゲル化による不具合が生じるため、カチオン型凝集剤を使用すべきである。
When the flocculant is blended in the coating composition of the present invention, the cationic flocculant is blended at a ratio of 1 to 10% by weight (based on 100 parts by weight of the aqueous coating composition). If the amount is less than 1% by weight, the effect of stopping the undercoating of the groundwork is not sufficiently exhibited. If the amount exceeds 10% by weight, the effect of preventing the axiety is increased, but the paint becomes gelled, thereby reducing the workability of the paint. Low storage stability. When the blending ratio is used, the effect of preventing agitation is sufficient, the coating workability is good, and the storage stability can be maintained well.
Typical examples of the cationic flocculant include dicyandiamide polyalkylene polyamine polycondensate, zinc acetate, aluminum acetate and the like. When a non-cation type aggregating agent (anionic type aggregating agent) is added, since a cationic acrylic emulsion resin and a cationic vinyl acetate emulsion resin are used as a binder resin, problems due to gelation occur. Cationic flocculants should be used.
本発明の塗料組成物に着色顔料を配合する場合は、着色顔料として酸化チタン、酸化亜鉛、酸化鉄、べんがら、カーボンブラック等が用いられる。着色顔料は５〜１５重量％の割合で配合する。５重量％を下回ると塗装したときの下地の隠蔽性が低下することとなり、１５重量％を上回ると多孔質素材壁面の質感を損なうこととなる。前記配合割合であると、けいそう土を含む既存塗膜の微少凹凸からなる質感を活かすことができる。 When a coloring pigment is blended in the coating composition of the present invention, titanium oxide, zinc oxide, iron oxide, red pepper, carbon black or the like is used as the coloring pigment. The color pigment is blended in a proportion of 5 to 15% by weight. If the amount is less than 5% by weight, the concealability of the base when coated is lowered, and if it exceeds 15% by weight, the texture of the porous material wall surface is impaired. When the blending ratio is used, it is possible to make use of the texture of the minute unevenness of the existing coating film containing diatomaceous earth.
着色顔料として光輝性顔料を使用する場合は、各種金属粉（金、銀、銅、真鍮、アルミ、亜鉛など）、メタリックカラー蒸着粉、着色マイカ粉、蓄光顔料などを使用できる。 When a bright pigment is used as the color pigment, various metal powders (gold, silver, copper, brass, aluminum, zinc, etc.), metallic color deposited powder, colored mica powder, phosphorescent pigment, and the like can be used.
本発明で用いる無機質粉体や着色顔料は、その粒径が大きすぎると塗り壁の意匠性を損なってしまうため、６０μm以下に調整する。
また無機質粉体や着色顔料を多量に配合すると、塗り壁の意匠性を損なうため、無機質粉体と着色顔料は合計で４０重量％以下とする。また光輝性顔料の粒径が大きすぎると光輝性が低下する為、光輝性顔料の粒径は６０μm以下に調整する。この光輝性顔料の粒径が６０μmを超えると、ローラーや刷毛などを用いて塗り壁などの下地に塗布する際、塗材による下地の隠ぺい力が落ちるなどの問題を有する。
The inorganic powder and color pigment used in the present invention are adjusted to 60 μm or less because the design of the coated wall is impaired if the particle size is too large.
In addition, if a large amount of inorganic powder or colored pigment is blended, the design of the painted wall is impaired, so the total amount of inorganic powder and colored pigment is 40% by weight or less. Further, if the particle size of the glitter pigment is too large, the glitter is lowered. Therefore, the particle size of the glitter pigment is adjusted to 60 μm or less. When the particle size of the glitter pigment exceeds 60 μm, there is a problem in that the hiding power of the base due to the coating material is lowered when applied to the base such as a coating wall using a roller or a brush.
本発明の塗料組成物に水系糊料を配合する場合は、水系糊料としてHEC（ヒドロキシメチルセルロース）、MC（メチルセルロース）、CMC（カルボキシメチルセルロース）等を用いることができる。
また、水系糊料は０．５〜１．５重量％の割合で配合する。０．５重量％を下回ると、塗料としての粘性が不足し塗装作業性が低下し、また長期的な貯蔵安定性も低下する。１．５重量％を上回ると粘性が高すぎて塗装作業性が低下し、長期的な貯蔵安定性も低下する。
When an aqueous paste is blended in the coating composition of the present invention, HEC (hydroxymethylcellulose), MC (methylcellulose), CMC (carboxymethylcellulose), or the like can be used as the aqueous paste.
The aqueous paste is blended at a ratio of 0.5 to 1.5% by weight. When the amount is less than 0.5% by weight, the viscosity as a coating is insufficient, the coating workability is lowered, and the long-term storage stability is also lowered. If it exceeds 1.5% by weight, the viscosity is too high, the coating workability is lowered, and the long-term storage stability is also lowered.

(Wall decoration method)
When using the water-based coating composition of the present invention, the water-based coating composition taken out from the bag or can is applied to the entire area of the coating wall base with a roller or a brush and dried. By doing so, it is possible to achieve an extremely beautiful surface finish without unevenness in color, and to make beautiful old walls.
Furthermore, an addition color pigment may be added to the water-based paint composition described above at the site of the application work. Also in this case, as specified in claim 8, the blending ratio of the color pigment is preferably 5 to 15% by weight in order to maintain the texture of the porous material wall surface.
さらに、必要に応じて、本発明の水系塗料組成物には、各種の添加剤として、消泡剤、防腐剤、分散剤、ｐＨ調整剤、レベリング剤、増粘剤、撥水剤、可塑剤、酸化防止剤、紫外線吸収剤、ハジキ防止剤、皮張り防止剤等の公知慣用の種々のものを、適宜、添加して使用することが出来る。これらの配合割合は、本発明の効果に影響を与えない範囲で添加することができる。 Furthermore, if necessary, the water-based coating composition of the present invention includes, as various additives, antifoaming agents, preservatives, dispersants, pH adjusters, leveling agents, thickeners, water repellents, plasticizers. In addition, various well-known and commonly used ones such as an antioxidant, an ultraviolet absorber, a repellency inhibitor, and an anti-skinning agent can be appropriately added and used. These blending ratios can be added within a range that does not affect the effects of the present invention.
本発明の水系塗料組成物を壁面に塗装するに当っては、ローラー、刷毛、吹付けガン等を用いて塗装することができる。塗膜の厚さは５０〜１００μmであり、５０μmを下回ると、下地に対する隠蔽性が低下することとなり、１００μmを上回ると下地の質感を損なうこととなる。 When the water-based coating composition of the present invention is applied to the wall surface, it can be applied using a roller, a brush, a spray gun or the like. The thickness of the coating film is 50 to 100 μm. When the thickness is less than 50 μm, the concealing property to the base is lowered, and when it exceeds 100 μm, the texture of the base is impaired.
本発明の壁面化粧方法によれば、けいそう土などに代表される多孔質素材を利用した壁面に対し、それらがもつ吸放湿性能や意匠性を損なうことなく、また古壁に対するアクシミ止め効果を持たせ、着色顔料や光輝性顔料などによって構成される塗材によって古壁を装飾することができる。 According to the wall surface decorative method of the present invention, the wall surface using a porous material typified by diatomaceous earth does not impair the moisture absorption and release performance and design properties of the wall material, and also prevents the scumming on the old wall. The old wall can be decorated with a coating material composed of colored pigments, glitter pigments, and the like.
