Concrete Solutions for architects, engineers and builders since 1974

Admixtures, Surface & Evaporation Retarders

Use Vexcon’s accelerating admixtures to increase the early set times and strength gains of concrete. Ideal for cold weather use and during normal temperatures for fast rack installations providing cost savings from quicker finishing of flat work and early form removal. Our acrylic admixtures will improve the strength, durability and resistance to chemicals, freeze-thaw cycles and UV light of finished concrete. Evaporation retarders are ideal to reduce the evaporation or cure rate and extend finishing time of fresh concrete on hot and windy days.

StarSeal Assist

Concentrate that reduces the rate of mositure evaporation in fresh concrete.Extends working time and assist in concrete slab finishing in rapid drying conditions.

STARSEAL ASSIST is an evaporation retarder that is applied to fresh concrete during finishing to extend working time.

When properly applied, StarSeal Assist forms a thin, continuous monomolecular film that reduces early moisture evaporation between the various placing and finishing operations, a major cause of plastic shrinkage cracking.

BENEFITS

  • Helps prevent plastic shrinkage cracking
  • Holds in surface moisture reducing evaporation rate
  • Extends finishing time
  • Minimizes rapid drying due to high wind, direct sunlight and high temperatures
  • Economical concentrate
  • Easy to use, just mix with water
  • DOT approved
  • Dyed yellow as visual application aid

StarSeal Assist RTU

Ready to use product that reduces the rate of mositure evaporation in fresh concrete.Extends working time and assist in concrete slab finishing in rapid drying conditions.

STARSEAL ASSIST RTU is a ready to use evaporation retardant that is applied to fresh concrete during finishing to extend working time.

When properly applied, StarSeal Assist RTU forms a thin, continuous monomolecular film that reduces early moisture evaporation between the various placing and finishing operations, a major cause of plastic shrinkage cracking.

BENEFITS

  • Formulated for instant usage
  • No dilution required
  • Helps prevent plastic shrinkage cracking
  • Holds in surface moisture reducing evaporation rate
  • Extends finishing time
  • Minimizes rapid drying due to high wind, direct sunlight and high temperatures
  • Dyed yellow as visual application aid

StarSeal Envio Set

Top surface retarder for exposing aggregate in horizontal and vertical concrete.

STARSEAL ENVIO SET is a concrete top surface retarding agent and conditioner. Apply to fresh concrete to inhibit the setting of the top surface layer while the remainder of the concrete cures normally. After the concrete sets or forms are removed, simply and easily remove StarSeal Envio Set and unhardened mortar to reveal a beautifully textured exposed aggregate surface.

BENEFITS

  • Allows removal of the top layer of freshly placed concrete to reveal the natural colors of the various aggregates
  • Water borne for environmentally sensitive areas
  • Pink color for ease of application
  • Easily exposes aggregate
  • Low odor
