A method for providing a high-build, low-sag coating by applying an aqueous coating composition including a waterborne polymer, preferably an emulsion polymer, having a glass transition temperature from 0 C. to 70 C., a hydrophobically modified polyurethane thickener, and a coalescent having solubility in water of less than 3 weight % and evaporation rate of at least 0.01(butyl acetate evaporation rate=1.0) to a substrate in a single coat having a thickness of at least 0.05 mm. when dried, and drying, or allowing to dry, the applied coating is provided. The aqueous composition and a curable composition are also provided.
