To provide a corrosion preventive coating material capable of securing excellent applicability even in the case of being used for a planar corrosion prevention object such as a steel sheet pile, and to provide a protective cover-fitted corrosion preventive coating material comprising the same.
Disclosed is a corrosion preventive coating material at least comprising a corrosion preventive sheet layer and a film layer pasted on the corrosion preventive sheet layer, and in which the corrosion preventive sheet layer is obtained by impregnating a base material at least with petroleum wax, and the film layer is porous at least in the pasted layer with the corrosion preventive sheet layer. Also disclosed is a protective cover-fitted corrosion preventive coating material at least comprising the corrosion preventive coating material and a protective cover. It is preferable that the film layer is a multilayer film comprising a base layer and a porous surface layer(s) formed on one side or both sides of the base layer, the base layer is a nonporous layer or a porous layer having independent pores, the surface layer is composed of a porous surface layer having independent pores and/or continued pores, and the film layer is pasted with the corrosion preventive sheet layer in the porous surface layer.
