Step 1:
Use
Chart 1
to estimate the number of LBS/1,000 square feet of
coverage (Example: 20 LB bag with 10,000 square foot coverage = 2.0 LBS/1,000 square feet)
Step 2:
Find the closest LBS/1,000 square feet in
Chart 2
that you estimated
using
Chart 1
(Example: 2.0 LBS/1,000 square feet = Spreader
Setting of 13)

Determining a Setting Rate Use chart below to determine the
Setting Rate
based on
Grams/
Squar
e Meter
of coverage as directed on the bag.
All spr
ead widths ar
e deter
mined by the particle size and density
.
Below will give approximate spr

The settings fur
nished on the Rate Setting Matrix ar
e intended as a guide only
. V
ariations in physical characteristics of material applied,
walking speed, and r
oughness of gr
ound surface may r
equir
e slightly dif
fer
ent spr
eader settings. Due to the above conditions, EPI
makes no warranty as to the uniformity of coverage actually obtained fr
om the settings listed.
