Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は防水材の下地処理工法に関するものであり、更
に詳しく云えば、通気性レジモル（レジンモルタル）を
使用して素地の水分及び気体を施工後除去するか、また

地の平滑性を得る施工工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a waterproofing material undercoating method, and more specifically, it uses a breathable resin mortar to remove water and gas from a substrate. The present invention relates to a construction method that is removed after construction or the pressure of gas is relaxed to prevent blisters and at the same time obtain smoothness of a base.
従来防水材で防水工事を行うに当たり、素地の水分及び
気体による防水材のフクレが耐久性、美観において、膜
厚の不均一が耐久性において、問題となっていた。Conventionally, when performing waterproofing work with a waterproof material, blistering of the waterproof material due to moisture and gas of the base material has been a problem in terms of durability and aesthetics, and unevenness of the film thickness in durability.
この解決には素地の乾燥などによる水分や気体の完全な
除去が要求されていたが、気象状況などに左右され、完
全な除去が不可能であった。このため、防水材の施工に
おいてフクレ及び下地の凹凸による防水材の問題が多数
発生している。For this solution, it was required to completely remove water and gas by drying the substrate, but it was impossible to completely remove it due to the weather conditions. For this reason, there are many problems with the waterproof material due to blistering and unevenness of the base in the construction of the waterproof material.
（問題点を解決するための手段・作用〕 本発明によれば、上記の問題は被塗面に通気性レジモル

ト、ＥＰＤＭゴムシート、塩ビシートが挙げられる。(Means and Actions for Solving Problems) According to the present invention, the above problems can be solved by applying a breathable resin on the surface to be coated and then applying a waterproof material to form a waterproof layer. Examples of the waterproof material here include coating type waterproof materials such as urethane elastomer, inorganic elastic waterproof material, synthetic rubber waterproof material and sheet waterproof material such as butyl rubber sheet, EPDM rubber sheet, and vinyl chloride sheet.
本発明に使用される通気性レジモルとは、比較的粒径の

は、例えば中心粒径が１４メッシュ、２０メッシュ、２
８メッシュ等であって、その粒度分布として中心粒径の
前後１０メッシュ以内に８０％以上の骨材粒子が含まれ
るものである。このように骨材の粒径がそろっていない
と、主たる骨材粒子の間隙に微小な骨材粒子が充填され
て通気性が悪くなるので好ましくない。The breathable regimol used in the present invention is composed of an aggregate and a binder having a relatively uniform particle size, and the aggregate / binder ratio is 1/4 to 1/20. As such an aggregate, for example, the median particle diameter is 14 mesh, 20 mesh, 2
The particle size distribution is 8 mesh or the like, and 80% or more of aggregate particles are included within 10 meshes before and after the central particle size as the particle size distribution. If the particle diameters of the aggregates are not uniform as described above, fine aggregate particles are filled in the gaps of the main aggregate particles, and the air permeability deteriorates, which is not preferable.
例えば、硅砂、ガラスビーズ、セラサンド、セラパール
の単独グレードとエポキシ、ウレタン、アクリル、合成
ゴム等のバインダーで作られるレジンモルタルを使用
し、配合比としてはバインダー／骨材＝１／４〜１／20
が望ましい。１／４以下ではバインダーが多すぎ通気性
を悪くし、１／20以上ではモルタルの強度が不足する。
このような配合でつくられたレジモルは骨材の隙間が完
全に開いており、その隙間を液体や気体が自由に通過で
き、従ってレジモルから水分や気体を除くことができ
る。For example, use a single grade of silica sand, glass beads, cerasand, and cerapearl and resin mortar made of a binder such as epoxy, urethane, acryl, and synthetic rubber. The compounding ratio is binder / aggregate = 1/4 to 1/20
Is desirable. If it is 1/4 or less, the amount of the binder is too large to deteriorate the air permeability, and if it is 1/20 or more, the strength of the mortar is insufficient.
In the regimol prepared by such a composition, the gaps between the aggregates are completely opened, and the liquid and the gas can freely pass through the gaps, so that the water and the gas can be removed from the regimol.
通気性レジモルの厚みは１mm以上であれば良く、それ以
下では骨材の粒径が小さすぎて十分な通気性が得られ

材又はシート接着剤を塗布し、シート防水で防水を行え
ばフクレの発生しない防水が可能となる。The thickness of the air-permeable resin is not less than 1 mm, and if it is less than 1 mm, the particle size of the aggregate is too small to obtain sufficient air-permeability, resulting in poor workability. Apply this breathable resin mortar to the surface to be coated (a primer may be used at this time),
If the surface of the breathable resin is stopped, a coating type waterproof material or a sheet adhesive is applied onto the surface, and the sheet is waterproof to prevent blistering.

008に合格するものが望ましい。The breathable regimol may be sealed as long as it has thixotropy and is not impregnated into the breathable regimol, but a two-component urethane putty and a waterproof material with anti-sagging additive are preferred. JIS A 6021, JIS A 6 as waterproof material
Those who pass 008 are desirable.
