BRUSH SELECTOR GUIDE - DISC

We provide brushes and pad holders that will give you the best possible performance between machine and ﬂ oor. Following are descriptions of the materials and their applications.

ProLite: Bristles are made from light-duty polypropylene for general scrubbing when you do not want to scratch or remove ﬁ nish from

the ﬂ oor. Recommended for use in place of red pads.

Prolene: Polypropylene material for medium-duty scrubbing on concrete, terrazzo and vinyl ﬂ oor tile. Recommended for use in place of

green or blue pads.

Union Mix: Medium grade natural ﬁ bers for polishing ﬁ nished ﬂ oors with standard-speed equipment. Recommended for use in place of

white pads.

AgLite Grit 500: For light scrubbing when used wet; bufﬁ ng or polishing when used dry on urethane coated, sealed concrete or other resilient

hard surface ﬂ oors. Recommended for use in place of red or white pads.

MidGrit 240: For general purpose scrubbing when you need a lighter action for sealed or unsealed concrete, stone, terrazzo, quarry tile and

other resilient hard ﬂ oor surfaces. Recommended for use in place of green or blue pads.

MidLite Grit 180: For general purpose scrubbing of sealed or unsealed concrete, stone, terrazzo, quarry tile and other resilient hard ﬂ oor surfaces.

Recommended for use in place of green or blue pads. Dyna Grit 80: For aggresive, heavy-duty scrubbing or stripping of ﬂ oors. Recommended for use in place of brown pads. Magna Grit 46: For extreme heavy-duty scrubbing or stripping of ﬂ oors. This brush has extra large diameter silicon carbide grit impregnated

synthetic bristles. Recommended for use in place of black pads. Short Trim Pad Holder: Made with a structural foam block and center ring for correct pad centering. It has a “shower feed” design for getting solution

to the ﬂ oor.

BRUSH SELECTOR GUIDE - CYLINDRICAL

We provide brushes and pad holders that will give you the best possible performance between machine and ﬂ oor. Following are descriptions of the materials and their applications.

Soft Nylon: Least aggressive brush available. Used on soft-ﬁ nish ﬂ oors where a more aggressive brush would leave

scratch marks, or in applications requiring very light cleaning.

Stiff Nylon: Cleaning action similar to polypropylene. More durable and wear-resistant than polypropylene.

Prolene: Low cost, yet effective in cleaning many common ﬂ oor surfaces.

MidLite Grit 180: Least aggressive grit brush. Used for daily cleaning of hard-ﬁ nished ﬂ oors.

Dyna Grit 80: Medium aggressive grit brush. Good all-around brush for medium to heavy buildup removal. Can also be

used for general stripping operations.

Magna Grit 46: Most aggressive grit brush. Used primarily to clean heavy buildup on concrete ﬂ oors in factories, or for

heavy stripping of ﬁ nish.
