Scrub Brushes
There are four different types of brushes available to
cover applications from cleaning heavily soiled floors to
polishing. A pad driver is also available to take
advantage of the many cleaning pads on the market.
Please refer to the following to assist in selecting the
proper brush or pad for the work at hand.
Uncoated Floors
Aggressive Grit
is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
Mild Grit
is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions. Advan-
tages are faster ground speed than nylon bristles on
light solid applications.
Polypropylene
is a general-purpose scrub brush with
stiff bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.
Finished Floors
Nylon bristles
are used in a variety of applications on
coated or uncoated surfaces.
White Pads
(Polishing) are used for dry polishing to
achieve a high-gloss appearance, or surface washing
on highly polished or burnished floors.
Red Pads
(Buffing) are used for light-duty scrubbing.
When used with a mild detergent they will provide
surface cleaning without removing the finish.
Blue Pads
(Scrubbing) are used for heavy-duty
scrubbing and light stripping. The blue pads remove
less finish than brown stripping pads, yet will remove
black marks, stains and dirt.
Black Pads
(Stripping) are used for easy and complete
removal of old floor waxes/finishes. They will quickly
remove ground in dirt, black heel marks, and spills.
When used with the proper stripper, this pad leaves the
floor clean and ready for finishing.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.
