A cure promoter composition is disclosed, including an accelerator which may include a thiocarbamate, a hydrated thiocarbamate, a dithiocarbamate, a thiazole, a mercaptothiazole, a sulfenamide, a thiazolesulfenamide, a metal salt of thiocarbamate, sulfur chloride, or combinations thereof. The cure promoter composition also includes a compatibilizing carrier, one or more organic solvents, a catalyst, an optional reducing agent, an optional reactive silane, an optional reactive organometallic, an optional gelling agent, and an optional aqueous component. A method for applying the cure promoter composition is disclosed, including contacting the organic solvents, the accelerator, the carrier, the reactive silanes, the reactive organometallics, the reducing agents, and the catalyst with one another to prepare the cure promoter composition, homogenizing the cure promoter composition, pausing after homogenizing to allow the cure promoter time to react, applying a sealant onto a substrate, and applying the cure promoter composition to a surface of the sealant.
