(DAYTON, Ohio) — Dayton Superior Corporation, North America’s premier concrete accessory manufacturer, and Grace Construction Products, a worldwide leader in the construction industry, have come together to form a unique manufacturing and distribution partnership for the Top-Cast® product line helping decorative concrete contractors and precast concrete producers. Top-Cast is a concrete surface retarder which helps contractors easily control the degree of exposed aggregate in finished concrete, bringing beauty and uniqueness to any decorative concrete or architectural precast concrete project.

Providing Winning Solutions for Today’s Decorative Concrete Contractor and Architectural Precast Concrete Producer

The Dayton-Grace alliance provides the concrete contracting community a program that is unparalleled in today’s construction market. Dayton Superior has a distribution network of over 3000 locations throughout North America that support the decorate concrete market; Grace has long been a technical and manufacturing leader in concrete construction products including architectural precast concrete and exposed aggregate slabs. Together this combination will bring better products to market faster, providing the contractor with state-of-the-art solutions.

Dayton’s expansive distribution network accelerates the delivery of innovative technologies and products to the concrete market, said Grace Product Manager, Brian Impellizeri. The Dayton-Grace partnership builds on the strengths of both companies and provides a proactive market strategy to meet the demands of the contractor, added Impellizeri.

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.
