The present invention relates to a mineral-based wetting primer composition for concrete waterproof polyurea, and a concrete polyurea waterproofing method using the same. The mineral-based wetting primer composition for concrete waterproof polyurea is formed by mixing a main material including 25-55 wt% of a water-soluble epoxy resin, 10-35 wt% of water, 25-45 wt% of a mineral binding agent formed of ordinary Portland cement, blast furnace slag fine powder, fly ash, attapulgite, trimethylamne, and silicon waste sludge, and 0.01-15 wt% of an additive, and a hardener including 25-55 wt% of polymercaptane, 5-10 wt% of modified aliphatic polyamine, 5-20 wt% of an anhydride hardener, 10-15 wt% of phenalkamine, and 10-35 wt% of a hardening accelerator at a ratio of 3-4 weights of a main material and 1 weight of a hardener. According to the present invention, the mineral-based wetting primer composition can be environmentally friendly without a smell, can be hardened at a low temperature below ...
