Evaporation Retarder - Concentrate

Evaporation Retarder is an evaporation retardant film for freshly placed concrete. This product retards the evaportation of moisture from fresh concrete surfaces by forming a monomolecular film on the surface. Evaporation Retarder is effective in combating rapid drying of the surface during adverse conditions including high temperatures, low humidity high winds, direct sunlight or interior work in heated conditions

Uses

• Fresh concrete surfaces where the evaporation rate exceeds the rate of bleeding of the concrete
• Exterior placements during times of low humidity, high winds, direct sun or temperatures exceeding 75˚F (24˚C)
• Interior placements in heated areas or with low humidity or areas subjected to drafts
• Large dry shake placements where surface moisture must be retained for proper installation

Key Advantages

• Reduces surface moisture loss by approximately 80% in windy conditions and 40% in direct sunlight Will not interfere with the adhesion of subsequentcuring & sealing compounds
• Reduces crusting, stickiness and sponginess which may cause uneven or poor surface texture
• Reduces plastic shrinkage cracking and wind crusting on flat-work
• Allows lower water content in concrete mix since Evaporation Retarder eliminates the need to add extra mixing water to the mix to compensate for rapid evaporation during finishing
• Keeps the surface plastic and finishable for a longer time

Mixing and Coverage Estimates

Evaporation retarder is supplied in a highly concentrated form and must be diluted prior to use. One (1) gallon of retarder should be mixed with nine (9) gallons of clean water to make ten (10) gallons of evaporation retarder.

These ten gallons should cover from 2,000 to 4,000 square feet of fresh concrete. Under severe conditions, more than one application of this product may be required.
