Abstract: The present invention provides two-component instant-set aqueous coating compositions that provide coating films having good film quality despite a rapid film build and set. The compositions comprise, as Component I, a film-forming aqueous anionically stabilized polymer composition, such as an elastomeric acrylic or vinyl polymer, and one or more surfactants; and, as Component II, a polycation tolerant mixture of polycation, an aqueous polymer composition, such as a film-forming acrylic emulsion polymer, and a nonionic or ethoxylated anionic surfactant having an average of 7 or more or, preferably, 9 or more ethylene oxide groups per molecule. Component I can be an elastomeric roof coating composition. The compositions can be co-sprayed to form coatings, e.g. roof coatings.
