Functional & Decorative Concrete Surfaces
TOP-CAST® Decorative Solutions help achieve an architectural finish with an exposed aggregate look. Our products are more than just a surface retarder — it’s a surface retarder that’s optimized for robust, consistent performance in all temperature and weather conditions. TOP-CAST® will create perfect, eye-catching flatwork that will satisfy both contractors and customers.
In twelve different specified depths, our TOP-CAST® Series (01-150) produces effects ranging from a barely-there acid-washed sheen to a stonney look. TOP-CAST® Series (01-150) is colour-coded, so the appropriate etch depth is easy to identify by contractors.

Sublime Ease-of-Use for Cast-in-Place Concrete
Surface retarders work by preventing the topmost layer of poured-in-place flatwork from curing. Once the rest of the concrete has cured, contractors can simply wash off the top layer. This achieves a texture that’s similar to the effect of sandblasting or acid washing concrete and even deeper exposure, but without any danger to workers or the environment. TOP-CAST® surface retarder has characteristics that make it one of the most effective and easy-to-use surface retarders on the market.
Stands Up to the Elements
TOP-CAST® surface retarder saves contractors on setup and installation time, and results in a more effective product. In addition, the surface retarder is designed to be extremely stable and robust, with the ability to resist temperatures of up to 150°F. Changes in weather, temperature, and humidity barely affect its efficacy.
Fire-and-Forget Technology
TOP-CAST® incorporates other innovations that make it extremely easy for contractors to work with.
For example, TOP-CAST® is colour coded so the appropriate etch depth is easy to identify by contractors.
The product will retard to a certain depth, and then deactivate on its own, leaving contractors free to concentrate on other issues.
