PURPOSE:To provide the high-degree crack following property and high shielding property for concrete to the title coated film by forming the film from a matrix with a dry coated film having >=50% elongation and a surface-treated cloth consisting of the fiber having >=20% elongation and having >=15kg/10mm tensile strength. CONSTITUTION:The concrete protecting composite coated film is formed from (a) a matrix (e.g., urethane rubber, acrylic rubber, etc.) with the dry coated film having >=50% elongation and (b) a cloth consisting of the fiber having >=20% elongation and surface-treated (e.g., plasma treatment, treatment with an adhesive, etc.) to improve the adhesive property to the matrix. For example, a concrete layer 1 is surface-treated with a primer, a putty, etc., coated with the matrix (a), laminated with the cloth (b), and further coated with the matrix (a) to form a coated film. In addition, the matrix (a) and the cloth (b) can be further coated.
