"When two leaders come together in a cooperative relationship such as this, only good things can happen," said Brad Costello, Product Manager for Dayton Superior. "Top-Cast® is a state-of-the-art product, something both decorative and flatwork concrete contractors and our distribution network are excited about," Costello added.

Top-Cast Surface Retarder

Top-Cast is the industry's only micro etch surface retarder. Water-based, Top-Cast is environmentally friendly and ideal for poured-in-place flatwork. It is available in 11 depths of etch to provide a comprehensive array of effects from micro-etch to fully exposed aggregate. Each grade is color and number coded for safety and convenience.

Each product grade of Top-Cast creates a unique degree of reaction to produce the desired effect. The retarding chemicals diffuse into the paste during the first hours of curing, and slow down the cement hydration reaction. The retarded surface does not require the contractor to cover with plastic, and can be washed off with a water hose and broom or pressurized water the same day or next day, depending on mix design and ambient conditions, revealing the aggregate in the concrete mix. Immediately after pressure washing and allowing the surface water to evaporate, the concrete can be sealed with Dayton Superior's Cure & Seal 30 EF, Ultra Seal 30 EF or a combination of the two to enhance the appearance and provide for a richer look with added protection. The Top-Cast combined with Dayton's Earth Friendly Cure & Seal 30 EF or Ultra Seal 30 EF (moisture insensitive sealers) provides the fastest turn-around time in the industry for exposed aggregate decorative concrete.
