Here you can see the range with a 25kg bag of de-icing agent on a 1.5m wide pavement.
Only 10g per square metre: With SNO-N-ICE you can spread twice the area as with the same amount of road salt. With 25kg of SNO-N-ICE you can cover 1,666m, whereas you run out of road salt after 833m.
As you only have to spread SNO-N-ICE once a day, you avoid expensive labour costs
