PURPOSE: Provided is a natural inorganic paint composition excellent in drying ability, coating workability, water resistance, and storage stability at 50deg.C, which dose not contain an organic solvent component. CONSTITUTION: The natural inorganic paint composition contains 12-32wt% of a potassium silicate resin, 0.5-15wt% of a butylacryl/styrene copolymer auxiliary resin having an emulsion average particle size of 50-250nm, 30-60wt% of a coloring pigment and an extender, 0.3-5.0wt% of a humid dispersant, a stabilizer, a thickener, and other additives, and 20-40wt% of water, wherein the potassium silicate resin contains SiO2 and K2O in the molar ratio of 2.6-4.0 and has a solid component of 28-32wt%. |
