Fair-faced concrete protective agent applied to special-shaped curb and application of fair-faced concrete protective agent

The invention relates to the field of road engineering, and particularly discloses a fair-faced concrete protective agent applied to special-shaped curbs and application of the fair-faced concrete protective agent. The fair-faced concrete protective agent is prepared from the following raw materials in parts by weight: 70 to 90 parts of fluorocarbon coating, 5 to 10 parts of nano filler, 2 to 8 parts of flexible fiber, 2 to 8 parts of curing agent, 1 to 5 parts of adhesion promoter, 1 to 3 parts of film-forming agent, 0.5 to 1 part of defoaming agent, 1 to 2.5 parts of dispersing agent and 10 to 22 parts of water. The application comprises the following steps: S1, preparing fair-faced concrete; s2, a protective agent is evenly sprayed to the surface of the bare concrete, a protective agent film layer is formed after the protective agent is cured, and the finished special-shaped curb is prepared; the coating has the advantages of being good in water resistance and weather resistance, stable in chemical propert
