Disk Brushes for Floor Cleaning: Scarifying, Scrubbing, and Polishing Guide

One Machine, Many Brushes — How to Match Disk Brushes to Your Cleaning Task

Floor cleaning machines are only as effective as the brush driving them. Using a polishing disk on heavy grease — or a scarifying brush on polished marble — wastes time and damages surfaces. Here is how to match the right disk brush to each cleaning stage.

Stage 1: Scarifying (Heavy Deposit Removal)

Scarifying disk brushes use hardened steel wire bristles mounted in segmented plastic disks. They scrape away compacted oil, grease, and dirt from unsealed concrete and industrial flooring. Scarifying is always a dry process.

Important: Steel wire can produce sparks — use non-spark phosphor bronze brushes in hazardous areas.

Stage 2: Heavy Industrial Scrubbing

After scarifying, heavy scrubbing disks use abrasive nylon filaments embedded with 46-grit to 120-grit silicon carbide. Pamin Tuff-Grit (1.7mm, 46-grit) is our most aggressive option.

Stage 3: General Scrubbing

Medium-duty scrubbing disks use polypropylene (0.6-0.8mm) or nylon (0.5-0.75mm) filaments. These are the workhorses of daily floor maintenance — effective on most sealed hard floors.

Stage 4: Polishing and Burnishing

Polishing disks use natural fibres (bassine, union fibre) or synthetic compounds. They run at higher RPMs (400+) and should always be used dry. Bassine is static-free, making it suitable for hazardous non-spark areas.

Carpet Shampoo Brushes

A separate category uses fine nylon, PP, or polyester filaments (0.25-0.5mm) for wet or foam carpet cleaning. These require a brush support centre to manage machine weight on soft carpet fibres.
