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

StarSeal Envio Strong

Acrylic admixture that improves flexural strength of cement based mixes. Reducing concrete slab cracking and Improving wear, impact, freeze/thaw and chemical resistance.

STARSEAL ENVIO STRONG is a technically advanced non re-emulsifiable modified vinyl emulsion polymer designed for use as an admixture to Portland cement mixes to improve adhesion and mechanical properties as an ASTM C 1059, Type II Bonding Agent.

Concrete or mortar prepared using StarSeal Envio Strong exhibits fast curing, good resistance to most common industrial chemicals, ultra violet light and high adhesion to many surfaces.

BENEFITS

  • Non re-emulsifiable
  • Improves bond strength
  • Increases durability under freeze/thaw cycling
  • Resists most common industrial chemicals
  • Reduces cracking
  • Interior and exterior use for vertical and horizontal applications

StarSeal Triple Set

Multi purpose calcium chloride based accelerating admixture designed to reduce set times, improve wear resistance, increase strength and workability of concrete and masonry.

STARSEAL TRIPLE SET is a chloride accelerating admixture for use in concrete, Portland cement and mortar.  StarSeal Triple Set is a ready to use liquid, added directly to the gauging water to reduce the water requirements and set times of concrete and mortar mixes.

StarSeal Triple Set improves workability, increases early and ultimate strength of concrete and mortar, and improves wear resistance properties.

BENEFITS

  • Reduces set time in cold weather applications
  • Increases early and ultimate strength of concrete and mortar
  • Improves workability
  • Assists in cold weather construction scheduling
  • Enhances the effects of air entraining agents

StarSeal Triple Set NC

Accelerating non-chloride admixture ensuring that the product does not contribute to the corrosion of reinforcing steel. Improves workability, strength and wear resistance properties of concrete and masonry.

STARSEAL TRIPLE SET NC is a non-chloride accelerating admixture for use in concrete, Portland cement and mortar. StarSeal Triple Set NC is a ready to use liquid, added directly to the gauging water to allow for cold weather placement of concrete, Portland cement, mortar and pre-cast members. It decreases critical cold weather set times leading to early high and ultimate increased strength and improved wear resistance properties. In addition, it reduces bleeding and segregation and improves workability.

StarSeal Triple Set NC contains no added chloride ions ensuring that the product does not contribute to the corrosion of reinforcing steel.

BENEFITS

  • Improves workability
  • Reduces set time in cold weather applications
  • Will not contribute to corrosion of reinforcing steel
  • Improves strength of concrete and mortar
  • Significant improvement in early stiffening and setting characteristics
  • Assists in cold weather construction scheduling
  • Reduces efflorescence
