The invention relates to a single-component organic silane modified polyether coating, which is composed of the following substances according to the total mass fraction of 100%: 25% to 45% of silane modified polyether, 10% to 15% of nano calcium carbonate, coloring 0% to 15% of additives, 20% to 30% of fillers, 0.2% to 1% of ultraviolet absorbers, 0.2% to 1% of ultraviolet stabilizers, 0.2% to 1% of antioxidants, 5% to 15% of plasticizers, 0.2% to 2% of water agent, 0.2% to 2% of coupling agent, 0.3% to 0.7% of drying agent and 5% to 10% of isoparaffin solvent. The invention also has very good adhesion to wet base surfaces, and is suitable for waterproofing of various base surfaces and various complex base surfaces; the construction environment is comfortable, and the weather resistance is good; the deformation adaptability of the base material is strong, and the mechanical properties are comparable to those of solvent-based single surfaces. The components of polyurethane waterproof coatings are basically the same; the storage stability is good.
