The invention discloses a surface-cracking-resistant paint for fair-faced concrete and an application method thereof. A base paint of the surface-cracking-resistant paint for fair-faced concrete belongs to a water-soluble inorganic paint which can reach and even surpass a carbonation resistance effect of a present concrete paint. The base paint has effects of preventing carbon dioxide from entering and increasing basicity of the surface of fair-faced concrete. Thus, the base paint has a dual-protection effect on carbonation of fair-faced concrete. Then, a top coating is applied to protect the base paint so as to allow the base paint to give play to a long-term carbonation resistance effect. Thus, the paint provided by the invention has a lasting protective effect on fair-faced concrete, and the surface of concrete remains original texture. In addition, the surface-cracking-resistant paint for fair-faced concrete has no special requirements on construction conditions and environment. It is not necessary to strictly process the surface of concrete, and toxic substances are not volatilized during the construction and using processes. The paint provided by the invention is harmless to the health of human body.
