spreader calibration information

Spreader Types

There are three basic types of spreaders available to apply deicers:

  • Broadcast – Used when covering very large areas, such as wide walkways or parking lots.
  • Bottom-drop – Used for more narrowed areas, such as sidewalks, or areas with sensitive vegetation nearby.
  • Hand-held – Used in very small areas and steps.

Using a Spreader

A spreader should be properly calibrated before use to accurately deliver the recommended application rate of a deicer. Calibration setting mechanisms are either dials or levers and differ between spreader makes and models.

Various spreader manufacturers tested samples of PELADOW® in their spreaders based on the recommended application rate. Listed below are their recommended settings for the leading spreaders on the market.

PELADOW RECOMMENDED APPLICATION RATE = 28 lbs. per 1000 ft2

Based on melting a thin sheet of ice at 20° F in 30 minutes. Always use the least amount necessary. Adjust based on ice thickness and temperature.
