The best practice is to purchase a product that is specially designed for snow and ice removal and then to closely observe the directions for use as shown on the package. Diamond Crystal® Solar Salt Extra Coarse and Diamond Crystal® Rock Salt may be used to remove snow and ice from concrete sidewalks, parking lots and asphalt surfaces. Diamond Crystal® Pellets with Softener Care™ Additive, Diamond Crystal® Red Out® Pellets with Iron Fighter® Additive, Diamond Crystal® Sun Gems® and Diamond Crystal® Red Out® Sun Gems® are not recommended for this use due to their large size.
Directions for Use: Remove excess snow. 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.
