A method of applying a construction material to an industrial article by impregnating a piece of fabric material (12) with a resinous pliable-mastic material (14) having the property that, while in its pliable condition, it readily adheres to surfaces of articles. This fabric has the further property that, upon exposure to aqueous moisture in a gaseous medium or water in the atmosphere or under water, it hardens spontaneously, holding the impregnated fabric material (12) in a moisture-impervious envelope (10) together with a charge of substantially dry gas (16) until used. The envelope is then opened and the impregnated fabric material (12) is applied directly to the industrial article in the presence of moisture. |
