PURPOSE: A polyurea paint composition is provided to give strength and tenacity inside molecular structure, thereby using for various usage like waterproofing, floor material, etc, and to increase the construction efficiency due to short hardening time. CONSTITUTION: A polyurea paint composition comprises: a resin mixture containing 20-40 weight% epoxy prepolymer, 20-40 weight% polyoxypropylene amine, 15-25 weight% cross-linking agent, 2-8 weight% pigment, and 2-8weight% additive; and a hardener, which is obtained by mixing 70-130 parts by weight polypropylene glycol, or polyoxypropylene diamine into 100.0 parts by weight isophorone diisocyanate or methylene diphenol diisocyanate. The volume ratio of the resin mixture and the hardener is 1:1. The polyoxypropylene amine comprises 16-33 weight% polyoxypropylenediamin, and 4-7 weight% polyoxypropylene triamine.
