Dry Cast Plasticizer

ConTec SP-306 combines a swipe agent with an effective mix lubricant and hydration aid. Its unique chemistry creates a low to moderate swipe appearance while its lubrication properties minimize both feed and compaction times. SP-306 is ready-to-use liquid for use in most low slump concrete masonry units. It improves compaction and density producing higher compressive strength and less permeable units.

Features & Benefits

  • Improves cement particle dispersion & hydration
  • Produces a low to moderate swipe
  • Increases compressive strength
  • Optimizes material flow to shorten machine cycle times
  • Creates more defined edges improving overall appearance
  • Reduces mechanical abrasion in equipment


ConTec SP-306 can be used in all types of manufactured concrete where low to moderate swipe is desired. SP-306 is not a water reducer.

ConTec TS-922 is available in bulk quantities or packaged in 55-gallon drims and 260 gallon totes. An ICT representative will work with you to determine the proper dispensing system to match your operation.


ConTec SP-306 must be stored at temperatures above 35 degrees, Care should be taken to prevent the product from freezing. Should SP-306 freeze, warm until completely liquid then use mechanical agitation to reconstitute.


The typical dosage range for ConTec SP-306 is 2-5 fl oz/100 lb (1330-325 mL/100 kg) of cement. As with most plasticizers, water content should be monitored to achieve desired appearance. Consult your ICT technical representative for recommendations and guidelines for your application.
