The invention relates to the technical field of waterproof coatings, in particular to a single-component polyurethane waterproof coating capable of being formed through one-time construction and application of the single-component polyurethane waterproof coating. The single-component polyurethane waterproof coating is prepared from the following raw materials: 25 to 30 parts of polyether glycol, 3 to 6 parts of polyether triol, 8 to 12 parts of diisocyanate, 10 to 20 parts of plasticizer, 30 to 45 parts of filler, 1 to 2 parts of pigment, 0.1 to 0.3 part of catalyst, 0.2 to 0.5 part of antioxidant, 0.2 to 0.5 part of ultraviolet light absorber, 0.2 to 0.4 part of defoaming agent, 0.3 to 0.5 part of dispersing agent, 1 to 2 parts of thixotropic agent, 0.2 to 0.4 part of base material wetting agent and 0.1 to 0.2 part of adhesion promoter. Wherein the thixotropic agent is a mixture of modified bentonite and a polyurea thixotropic agent in a mass ratio of (1-1.6): 1. The single-component polyurethane waterproof
