Top Cast

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.
