MasterKure ER 50 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.
It can be used in concrete surfaces where the evaporation rate exceeds the bleed rate, air-entrained and non-air-entrained concrete. silica-fume concrete. concrete containing fly ash.
- 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
- Reduces surface moisture evaporation approximately 80% in wind and approximately 40% in sunlight to reduce plastic shrinkage cracking and wind crusting
- Allows reduced slump and water content in concrete to facilitate proper hydration of high-strength mixes
- Facilitates the use of air-entrained concrete to make air entrainment possible in rapid-drying conditions
- Prolongs surface plasticity for longer working time in hot, dry, or windy conditions
