It is an object to obtain a water-curable supporting bandage which can be applied to even an affected part of complicated shape with sufficient time, when it is applied by winding it around an affected part such as bone fracture for fixing. A supporting bandage comprising a water-curable polyurethane pre-polymer composition held on the fabric material is applied to an affected part without water supply. Sufficient time can be taken for application of the supporting bandage to the affected part. After completion of the application, the polyurethane prepolymer is rapidly cured by supplying water from outside of the supporting bandage to obtain a sufficient strength. The fabric material of the supporting bandage has from 15 to 33 apertures per cm<2 >and a numerical opening rate of aperture of from 14 to 35%, and is flexible. This fabric material is covered with a water-curable polyurethane prepolymer composition comprising a polyurethane prepolymer containing a polyol and polyisocyanate, and a catalyst. In this polyurethane prepolymer composition, an ethylene oxide component of the polyol is contained in an amount of 12 wt % or higher.
