With summer right around the corner, extra precautions must be taken to avoid concrete damage from hot and dry conditions during curing. When moisture is evaporated too quickly from newly poured concrete, significant shrinkage and cracking will occur. Warm temperatures, low humidity, and wind all contribute to accelerated evaporation rates.
EVAPRE evaporation retardant is a high quality, cost-effective, water-based compound specifically designed to effectively reduce the rate of surface evaporation. EVAPRE forms a thin monomolecular film to reduce rapid moisture loss from the concrete surfaces prior to curing, giving newly poured concrete the time needed to gain sufficient strength to resist unwanted shrinkage, cracking, wind crusting, stickiness, and sponginess, which often cause poor and uneven surface texture. Once the concrete begins to set, the protective film shield disappears.
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. With rapid evaporation stunted, slab surface conditions will be normalized and workers can adhere more closely to established finishing schedules.
W. R. MEADOWS also offers EVAPRE-RTU, a ready-to-use, pre-mixed alternative to EVAPRE. EVAPRE-RTU is time saving and easy to apply.
EVAPRE and EVAPRE-RTU are both VOC-compliant.
