SODIUM CHLORIDE ( Rock Salt)

 

Rock salt is the most economical product to melt ice and loosen packed snow. Rock salt is made up of a mixture of large and small crystals of naturally occurring sodium chloride. The small rock salt crystals melt instantly, while the larger ones provide traction and dissolve steadily to provide relief longer. Rock salt works best at temperatures above 5 degrees Fahrenheit and should be used sparingly, spread 1/2 to 1 cup per square yard evenly over ice and packed snow surfaces.

Quantity and melting action will depend upon temperature and thickness of the ice and packed snow. Reapply as necessary. When ice and snow soften, remove slush and any excess ice melter from pavement for good concrete maintenance. Notice: All ice melting agents work by reducing the freezing point of water. This can result in more frequent freeze-thaw cycling of the melted snow and ice, which can cause spalling (surface scaling of concrete). As such, use only on properly placed, cured and sealed, air-entrained concrete.

To lessen the possibility of freeze-thaw cycling and potential damage, promptly remove slush as it is formed. Do not use on porous or improperly cured concrete, concrete less than one year old, wood or other porous materials. As with any ice melting agent, particular care should be used when grass and vegetation are adjacent to the deicing surface as excess application may cause damage. Use this product at your own risk.
