Ice melt featuring an optimal blend of magnesium chloride, calcium chloride, and sodium chloride. Max-Blend 5300 melts ice and snow fast, while keeping surfaces clear longer. Melts ice down to -10 degrees Fahrenheit/-23 degrees Celsius. Features a unique formulation that resists refreezing so fewer applications are needed. Safe when used as directed on air-entrained, cold-weather concrete that is at least 1 year old. Use 1 cup (10 ounces) of ice melt per square yard and spread evenly, avoiding piling or overspreading. Remove resulting slush. Reapply ice melt as needed.
