Sika® Antisol® ER 50

(former MasterKure® ER 50)

EVAPORATION REDUCER

Sika® Antisol® ER 50 evaporation reducer reduces surface moisture evaporation from freshly placed concrete, especially in rapid drying conditions, such as high concrete surface or ambient temperatures, low humidity, high winds, direct sunlight, or work in heated interiors during cold weather.

  • Does not affect concrete strength (early and ultimate), abrasion resistance, and durability
  • Reduces or eliminates crusting, stickiness, and underlying sponginess, resulting in a consistent surface
  • Allows reduced slump and water content in concrete to facilitate proper hydration of high-strength mixtures
  • Reduces surface moisture evaporation by approximately 80% in wind and approximately 40% in sunlight to reduce plastic shrinkage cracking and wind crusting
  • Prolongs surface plasticity for longer working time in hot, dry, or windy conditions

Application

Consumption

Coverage

  • One gallon (3.8 L) of Sika® Antisol® ER 50 mixed with nine gallons (34.1 L) of water yields 10 gallons (37.9 L) of sprayable solution.
  • 10 gallons of Sika® Antisol® ER 50 solution (1 to 9) should cover 2,000–4,000 ft2 (186–372 m2) of fresh concrete.
  • If more than one application is required, e.g., in adverse drying conditions, additional material will be required.
Application steps

APPLICATION

  1. Agitate Sika® Antisol® ER 50 before mixing with water. Depending on the application, mix at a ratio of up to 1 part Sika® Antisol® ER 50 concentrate to 9 parts water. Re-agitate mixed materials before applying.
  2. Apply with a constant pressure or industrial sprayer.
  3. Sika® Antisol® ER 50 forms a monomolecular film when sprayed onto the concrete surface immediately after screeding or between finishing operations (as needed). The protective shield of Sika® Antisol® ER 50 usually lasts as long as the concrete remains plastic, despite succeeding floating operations. When applying surface hardeners using the delayed application method, use Sika® Antisol® ER 50 after screeding. When applying surface hardeners using the early application method, use Sika® Antisol® ER 50 only after the specified quantity of dry shake has been incorporated into the concrete by floating and after the first floating operation, if necessary.
  4. Treated surfaces are easily distinguished from untreated surfaces because of the greenish-yellow color of the film in the presence of moisture and light. The fluorescent tint of the film disappears completely upon drying. The residue remaining on the surface of hardened concrete does not impair bonding or alter color.
