Concrete Surface Retarders & Deactivators
Surface retarders, also called surface "deactivators," are applied to fresh concrete to chemically delay the set of the surface mortar. Unlike concrete set retarders, they allow the rest of the concrete to cure normally, without affecting the setting rate or strength gain. Because surface retarders work by stopping the hydration process ...
