The present invention relates to an eco-friendly complex paint composition and a construction method for protecting surface of steel structure and concrete structure using same, in which paint is prepared by using a modified unsaturated polyester resin as a base resin and adding a curing agent, such as metallic salt hydroxide. At this point, the present invention provides an eco-friendly complex paint composition and a construction method for protecting surface of steel structure and concrete structure using same, in which the metallic salt hydroxide is preprocessed to introduce an organosilane group on to a surface thereof, so that an increase in viscosity is prevented and isoprene rubber is included to prevent a contraction, so that a crack problem can be solved. Paint for protecting surfaces of steel structures and concrete structures according to the present invention has superior adhesiveness to surfaces of steel structures and concrete structures to be painted, has superior properties, such as durability, weatherability and waterproofness, and has very good uniformity of formed paint film and good performance of preventing generation of surface cracks. Therefore, a superior effect of protecting surfaces of steel structures and concrete structures can be provided. |
