The present invention includes 13 to 75% by weight of a polymer binder, 8 to 50% by weight of a cement binder, and 3 to 45% by weight of a filler. The polymer binder comprises 60 to 99% by weight of an acrylic emulsion and methyl methacryl. Finishing coating composition of water-side manholes and pump station manholes comprising 0.1-15% by weight of acrylate resin, 0.1-15% by weight of siloxane emulsion and 0.1-15% by weight of ethylene vinyl acetate emulsion, preparation method of water-side manholes using the same, and preparation of pump station manholes It is about a method. According to the present invention, by using an acid-resistant cement-based binder, a polymer binder having excellent durability and adhesion, a filler having excellent durability and insulation against acid, salt, and the East Sea, it is excellent in strength, high fluidity, elasticity, adhesion and durability, and particularly acid resistance and A manhole excellent in heat insulation can be manufactured. |
