Anti-Icers & De-Icers
ABOUT ANTI-ICERS & DE-ICERS
• An ANTI-ICER is used as a pre-treatment before a storm to prevent bonding of snow and ice to the surface. This makes
snow removal much easier.
• A DE-ICER is applied after a storm.
• De-Icers work by lowering the freezing point of water.
• Every de-icer has a characteristic minimum temperature at which it can melt ice.
• After a de-icer is applied and begins melting ice, the concentration becomes diluted and the minimum melting
temperature rises.
• This freezing point gradually increases and eventually will reach a point where it will not permit further melting.
• Chemical de-icers are not designed to be a complete substitute for snow removal but should be used as an aid to simplify
removal by other means, such as by shovel, blower or plow.
APPLICATION INFORMATION
• Anti-Icers should be applied before a storm at 1/2 gallon per 1000 square feet.
• De-Icers should be applied at a rate of 1 gallon per 1000 square feet for thin ice. When ice is more than one inch thick,
apply at a rate of 3 gallons per 1000 feet.
