WINTER DOW Calcium Flake Ice Melt 50#

DOW Calcium Chloride Flake Ice Melt – 50 lb Bag

Conquer severe winter storms with confidence using Dow Calcium Chloride Flake Ice Melt, an 83% to 87% pure, natural-brine formula engineered to perform when temperatures plunge to -25°F. Designed with an integrated dust suppressant for cleaner handling, these high-performance flakes generate rapid exothermic heat to clear commercial entryways, parking lots, and walkways fast. Beyond winter ice control, this versatile industrial solution doubles as an effective dust suppressant for gravel access roads and a reliable cold-weather concrete accelerator for local construction projects throughout East Greenwich, Rhode Island and surrounding southern New England job sites.

Key Features & Benefits

• Rapid Exothermic Heat: Delivers immediate melting power upon contact to break the bond between ice and pavement quickly in sub-zero conditions.

• Extreme Low-Temperature Range: Actively melts ice and packed snow effectively down to -25°F (-32°C).

• Dust-Suppressed Handling: Formulated to minimize airborne dust during loading, spreading, and commercial application.

• Dual-Purpose Utility: Functions as a high-efficiency winter de-icer, road dust control agent, and cold-weather concrete set accelerator.

• High-Purity Composition: Contains 83% to 87% pure calcium chloride flakes sourced from natural brine for maximum melting capacity.

• Convenient Packaging: Supplied in a moisture-resistant 50 lb bag designed for easy lifting, stacking, and spreader loading.

Ideal Applications

• Commercial parking lots, retail sidewalks, and building entryways

• Gravel access roads, active construction sites, and unpaved haul roads for dust suppression

• Cold-weather masonry and concrete placement projects requiring set acceleration

• Industrial facility maintenance and winter safety management

Frequently Asked Questions

• How much area does a 50 lb bag cover? For standard ice clearing, one 50 lb bag covers approximately 1,000 to 1,500 square feet, depending on ice thickness and ambient temperature. Apply lightly at a rate of 2 to 4 ounces per square yard.

• Can this product be used on newly poured concrete? Do not use calcium chloride on concrete that is less than one year old or on poorly finished surfaces to prevent potential surface scaling.

• How does calcium chloride compare to standard rock salt (sodium chloride)? Calcium chloride works significantly faster and remains effective at much lower temperatures (-25°F vs. 15°F for rock salt), while requiring less product per square foot to achieve results.

• What is the best way to store opened bags? Store unused flakes in a tightly sealed, moisture-proof container in a dry area to prevent clumping, as calcium chloride readily absorbs moisture from the air.

Pro Contractor Tip

When utilizing calcium chloride flakes as a concrete accelerator during sub-freezing masonry work, dissolve the flakes in the mix water rather than adding them directly to the dry aggregate to ensure uniform distribution and prevent flash setting.
