PROBLEM TO BE SOLVED: To obtain an aqueous slurry having a rheological characteristics and a coating film-forming performance capable of forming a coating film of a specific thickness on a perpendicular surface and suitable for building and civil engineering work by admixing a hydraulic and/or air-hardening inorganic binding material, inorganic fine particles and/or an inorganic aqueous solution with water. SOLUTION: An inorganic fine particle and/or an inorganic aqueous solution is contained in an effective amount to impart an aqueous slurry with characteristics rendering it possible to form a coating film thicker than 1 mm on a perpendicular surface. The inorganic fine particle means an inorganic particle of the colloidal dimension or an inorganic fine particle containing an inorganic particle of the colloidal dimension. As the inorganic colloidal particle are exemplified colloidal silica, colloidal silicic acid, colloidal alumina and the like. The inorganic aqueous solution is an aqueous solution wherein an inorganic compound is dissolved in water and is originally in a state of an aqueous solution, and water glass is exemplified. This aqueous slurry may contain a foaming agent as required.
