PROBLEM TO BE SOLVED: To eliminate asbestos which is sprayed onto ceiling or its beam as refractory material, without scattering of the same. SOLUTION: The invention relates to the treating agent for releasing applied asbestos layer comprising an aqueous solution of ionically cross linking polysaccharides, excellent in hydrophilicity, water retention, appropriate viscosity, permeability, and safety different from conventional products and has a high gel strength. The invention provides various excellent effects such as handling, remarkable reduction of re-scattering by combined use of a sticky emulsion, and provides easy judgement of appropriate spraying amount and indication that the subject to be sprayed is dangerous by combined use of a coloring agent.
