A non-woven nylon, polyester, or natural fibre disc up to 1" thick. Each disc has various types and sizes of intertwined fibers, some of which may have grit particles bound to the fibre surface. Coarseness of the pad determines its use: least coarse for buffing, with increasing coarseness for scrubbing and stripping. Pads are color-coded to designate their coarseness and use. Lighter-color pads tend to be less abrasive, with darker-color pads being the most abrasive. Pad manufacturer's generally follow these guidelines:

1. Natural fibre for burnishing; 2. White for polishing; 3. Beige for buffing; 4. Red for spray-buffing and light scrubbing; 5. Blue or green (medium abrasive) for scrubbing and stripping; 6. Brown or black (extremely abrasive). Armstrong does not recommend the use of brown or black pads on any of our resilient floors.
