PROBLEM TO BE SOLVED: To largely improve coating workability of an inorganic coating by largely increasing viscosity of an inorganic binder by a slight amount of addition in thickener for inorganic binder and inorganic coating. SOLUTION: Guar gum-based polysaccharide, xanthan gum-based polysaccharide or Locust bean gum-based polysaccharide is used as the thickener for inorganic binder, and No.3 sodium silicate, lithium silicate, potasium silicate, colloidal silica or ethyl silicate is used as the inorganic binder. As a result, viscosity of each inorganic binder is largely increased by addition of 1 wt.% each polysaccharide and a film thickness exhibiting resistance to sagging and a film-forming property as the inorganic coating are largely improved. The inorganic coating excellent in coating workability is obtained by using the thickener and the polysaccharide. COPYRIGHT: (C)2005,JPO&NCIPI
