PURPOSE: An eco-friendly surface protecting method is provided to apply salt-caused damage preventing function, an anti-neutralizing function, a water-repellent function, and an anti-corrosion function to the surface of a concrete structure. CONSTITUTION: The surface of a concrete structure is treated(S10). The surface of the concrete structure is washed based on a high pressure(S20). A putty material is applied on the surface of the concrete structure(S30). A base coating layer is formed on the surface of the concrete structure based on a surface protecting agent, and a primary curing process is implemented(S40). A middle coating layer is formed on the surface of the base coating layer based on the surface protecting agent, and a second curing process is implemented(S50). A top coating layer is formed on the surface of the middle coating layer based on the surface protecting agent, and a third curing process is implemented(S60). The surface protecting agent is composed of an epoxy base resin component and a hardening component. The epoxy base resin component includes an epoxy resin, a reactive diluents, a coagulant, an emulsifier, and water. The hardening component includes polyoxypropylenediamine, toluene, titanium oxide, garamite, a pigment, and water.
