Rapid Set® FLOW CONTROL® is a flow enhancing additive that allows higher fluidity or lower water requirement. Reducing water content by adding FLOW-CONTROL will increase the final strength and durability.


Use FLOW CONTROL with Rapid Set cement products. Add 1 to 4 packets of FLOW CONTROL to increase fluidity, and/or increase strength to satisfy jobsite requirements. A trial batch is recommended to fine-tune the dosage. FLOW CONTROL may be used in combination with all other products of the Rapid Set® Concrete Pharmacy®.


  1. Place desired amount of potable water into mixing container.
  2. Add half cement product into mixing container and mix with mechanical drill/mixer.
  3. Continue mixing while adding FLOW-CONTROL 2.1-oz (60-grams) powder to mixing container.
  4. Add remaining cement product into mixing container. Follow product mixing instructions and maximum water requirements described on the package of the cement product.
  5. Mix to a workable, lump-free consistency. Do NOT exceed 4 packets per 50-lb to 70-lb bag of Rapid Set branded cement product. Too much water in the mixture may cause aggregate segregation, which can reduce strengths.
