Expose the beauty. Control the depth. Dayton Superior Top-Cast® Surface Retarder is a professional-grade, spray-applied surface retarder designed to create consistent, high-quality exposed aggregate finishes. Ideal for decorative flatwork, this top-surface treatment delays the set of cement paste at the surface only — allowing you to wash off the cream and reveal the aggregate beneath. From subtle sand exposure to full decorative aggregate, Top-Cast gives you predictable, repeatable results. Ideal For: Exposed aggregate flatwork Sidewalks, plazas, and drive lanes Architectural concrete Decorative commercial and residential projects Features: Top-surface application for controlled exposure Available in multiple grades for varied depth Uniform, consistent finish Easy spray application Water-based and environmentally conscious formulation Size: 5 Gallon Pail At Pretty Concrete Store, we supply the materials that elevate the craft — because exposed aggregate should look intentional, refined, and beautifully executed.
