MAG Pellet Flake Bags
Magnesium Chloride is considered (by some) as the best total ice-melter that is less corrosive on metal surfaces, protects concrete from spalling, is less toxic and environmentally as safe as Calcium Chloride and much less corrosive than Sodium Chloride (rock salt).


  • MAG is less irritating to the skin.
  • MAG corrodes metal surfaces less.
  • MAG is safer around vegetation.
  • MAG is safer on concrete.
  • MAG is safer for use around animals and humans.
  • MAG is environmentally friendlier.
  • MAG Brine is an effective road salt prewetting agent.
  • MAG is an effective tennis court conditioner.
  • MAG can be used for tire ballasting.


Description: Large, flat, clear to off-white flakes containing over 51% water of hydration.

Relative deicing speed: Starts about as fast as calcium chloride, but may become diluted and ineffective.

Lowest practical temperature: Down to 5° F.

Effect on concrete: Chemical attacks concrete at a “slow rate”. Can cause damage from freeze-induced expansion pressures by increasing number of freeze/thaw cycles.

Effect on vegetation: Used as recommended, will not harm vegetation. However, magnesium chloride, on a percentage basis, contains 17-56% more chloride ions that other “salt” type deicers.

Residue: Leaves no powdery residue.

Manufacturer’s recommended application rate: Below.

Comments: Flake magnesium chloride contains over 51% water. It starts deicing almost as fast as calcium chloride but may become diluted and ineffective. *”Slowly” attacks concrete chemically.

*Reference for “slow” rate of concrete attack per American Concrete Institute, ACI 201 2R-92, Guide to Durable Concrete.


On unpaved roads, construction sites and parking lots:

MAG should be applied on the basis of up to 2 lb/sq. yard, and reapplied at 50% of this rate when the surface appears dry. Road surfaces should be graded prior to MAG® application.

On tennis courts or recreation fields:

MAG should be applied on the basis of up to 1 lb/sq. yard, and reapplied at 50% of this rate when the surface appears dry:
