The present invention relates to a polyurea resin composition for a high permeability waterproof paint and a method of constructing a polyurea waterproof coating using the same, and to explain in more detail, the subject is, based on 100 parts by weight of a prepolymer containing isocyanate at the end, a silver nanocolloid solution 5 to 20 parts by weight, 3 to 10 parts by weight of a particle dispersant, 0.5 to 3 parts by weight of an antioxidant, and the curing agent, based on 100 parts by weight of polyoxypropylenediamine, 30 to 70 parts by weight of diethyltoluenediamine and , 5 to 15 parts by weight of alkali silicate, 5 to 12 parts by weight of polyoxyethylene castor oil, 0.5 to 3 parts by weight of UV stabilizer, 0.2 to 2 parts by weight of antifoaming agent are included, so that the antibacterial property is excellent and there is no fear of discoloration. The present invention relates to a polyurea resin composition for a highly permeable waterproof paint that has an effect of penetrating into concrete and reinforcing the internal structure densely, and a method of constructing a polyurea waterproof coating using the same. |
