Unique sizing mixture of large and small crystals of natural sodium chloride - small crystals melt on contact and large crystals provide longevity and instant traction. Leaves no oily residue.
The smallest crystals dissolve quickly white the larger crystals last longer, reducing the amount of rock salt needed to get the job done. It may be used on most surfaces ranging from blacktop, wood, stone, and gravel to properly cured air-entrained concrete.
