Zusammenfassung:	PROBLEM TO BE SOLVED: To provide one-liquid moisture-curing polyurethane coating waterproof material in condition of good working environment without using a low-molecular organic solvent. SOLUTION: The one-liquid moisture-curing polyurethane coating waterproof material, in which the viscosity is in the range of from 6,000 to 50,000 mPa s/23°C, is obtained by mixing (C) an isocyanate group terminal prepolymer with (D) a CO2gas absorbent, (E) a filler, (F) a plasticiser and (G) an accelerator, wherein (C) the isocyanate group terminal prepolymer is obtained by reacting a polyol component with an isocyanate component, in which the ratio of containing isocyanate group of a produced isocyanate group terminal prepolymer is 1.5-3.6% by mass, when (A) the polyol component containing 40-80% of a polyoxytetramethylene glycol, in which the number average molecular weight is 250-4,000, in hydroxyl equivalent in the mixture of polyol is reacted to (B) a polyisocyanate.
