CMA40 application rates vary according to climate and maintenance practices. CMA40 is applied at rates similar to road salt, but heavier in the first application and lighter as the storm continues.
Apply early in the storm to prevent snow/ice bonding. Typical rates for the first application:
300 to 400 lbs./lane mile
5 to 15 lbs./1000 square feet
20 to 40 grams/square meter
Wait at least 20 minutes to remove snow/ice. Re-apply when snow/ice accumulation shows first tendency to pack (bond); plow regularly.
