EVAPRE evaporation retardant is an economical, high quality, water-based compound. It is specifically designed to form a thin monomolecular film to reduce rapid moisture loss from the concrete surfaces prior to curing. EVAPRE provides a significant aid in producing high-quality concrete flatwork. Rapid evaporation of water is retarded, slab surface conditions are normalized, and workers can adhere more closely to established finishing schedules. EVAPRE is also VOC-compliant.

EVAPRE significantly reduces plastic shrinkage and cracking, wind crusting, stickiness, and sponginess, which often cause poor and uneven surface texture. These conditions result when the hydration is more rapid than the movement of bleed water to the surface. EVAPRE effectively combats and minimizes the effects of rapid-drying conditions such as low humidity, low dew point, high winds, direct sunlight, hot weather, heated concrete, or placement of concrete in a heated enclosure or interior area during cold weather. The protective film shield disappears as soon as the concrete is no longer plastic.

Features

• Significantly reduces plastic shrinkage and cracking caused by evaporation in low humidity, high temperatures, and high winds.
• Allows use of lower slump and lower water: cement ratio concrete.
• Provides smooth and durable concrete flatwork.
• Reduces wind crusting, stickiness, and sponginess, which often cause poor and uneven surface texture.
• Allows finishing crews to adhere to established schedules.
• Reduces overall cost because timing of finishing operations is less critical.
• VOC-compliant.
• Helps minimize surface cracking due to early water loss of silica fume concrete.
