受ける為に耐用年数が短かい。(1) The paint film is thin and the painted surface is exposed to the outside world, which causes corrosion of marine steel structures due to water quality, quicksand velocity, contact with ships or wood, etc.
Their service life is short because they are directly affected by marine organisms, temperature, ultraviolet rays, etc.
(2) 有機系又は樹脂系の塗料を用いて塗布膜を厚
くすることは非常に高価な施工費用を要する。(2) Increasing the thickness of the coating using organic or resin-based paints requires very high construction costs.
(3) 有機系又は樹脂系の塗布面に無機系の被覆保
護材を直接に接着させて塗り厚を厚くすること
は技術的に困難である。(3) It is technically difficult to increase the coating thickness by directly adhering an inorganic protective coating to an organic or resin-based coated surface.

セメント系被覆保護材７を厚く付着せしめる。(3) An inorganic material such as cement slag or cement mortar is prepared by applying an adhesive effective for inorganic cement to the surface of the aggregate 6 fixed on the surface of the adhesive and adding various admixtures by brushing, troweling, or spraying. The cement-based covering protection material 7 is thickly applied.
(4) 硬化した無機セメント系被覆保護材７の表面
に防水剤８を塗布する。(4) Apply a waterproofing agent 8 to the surface of the hardened inorganic cement-based coating protection material 7.
本発明方法は上記の通りであるから極めて容易
