Mercer Industries 447080 Floor Sanding Screen Disc, 80 Grit
The Mercer 447080 comprises 10 discs designed for 20″ floor buffers or rotary machines. With an 80 grit, these screen discs are suited for removing old finishes, wax, and rough work on worn wood floors. They can also strip paint, varnish, glue, and wax from hardwood, concrete, stone, and tile surfaces. The open-screen construction helps debris separation and cooling during use, contributing to consistent performance on large surface areas.
Mercer Industries 430036 Silicon Carbide Cloth Back Floor Disc
This 20″ cloth-backed disc comes in a 20-pack with 36X (silicon carbide) grit, suitable for hardwood and concrete prep. The heavy X-weight cloth backing provides strength and durability for extended use on a floor buffer. The disc’s grit profile offers steady material removal with predictable results, helping you prepare surfaces before finishing or refinishing.
Mercer Industries 45020G Green Floor Maintenance Pad
This 5-pack includes 20″ green maintenance pads designed for floor buffers. The green pad is intended for wet scrubbing and can be washed and reused. Pads are typically used to maintain finish and clean surfaces without removing substantial material, and they can be used on both sides for extended life on the machine.
Floor Sanding Mesh Finishing Screens (20 Inch)
These 20″ finishing screens use silicon carbide grains for light abrading and scuffing, ideal for between-coats refinishing work on wood or stone floors. They are designed to be used with a pad and pad driver and are suited for low-speed buffers (175-350 RPM). The mesh construction allows debris passage and some cooling during use.
3M Buffer Pad 5100 Red 20″ (5/Case)
The 3M 5100 red pad is a light-duty pad intended for everyday cleaning under automatic scrubbers and spray buffing. It helps remove light soils and scuff marks while preserving finish. The pad is designed to work with water-based finishes and is compatible with typical 20″ floor buffers.
Mercer Industries 447120 Floor Sanding Screen Disc, 100 Grit
Though shown as a 19″ option in some listings, the 447120 line uses a 20″ diameter screen disc format with 100 grit. It is designed for use on floor buffers, making it suitable for removing finishes, smoothing surfaces, and preparing floors for finishing. This option complements coarser grits for an efficient workflow on large areas.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm your floor buffer’s pad driver type and center hole configuration (2″ is common) to ensure proper fit with 20″ discs and pads.
- Grit Range: Coarser grits (36X, 80) remove material quickly, while finer grits (100, 120) refine surfaces and prepare coatings. For best results, pair coarse removal with intermediate finishing grits.
- Backing Material: Cloth-backed discs offer strength for heavy-duty work; mesh and screen discs promote debris clearance and are good for finish work between coats.
- Pad Type: Maintenance pads (green pads) are suitable for wet scrubbing; finishing screens are ideal for light scuffing between coats; stripper pads handle heavy finishes but require caution on sensitive flooring.
- Durability & Reusability: Consider reusable pads for cost efficiency and reduced waste. Some pads are washable; others are single-use depending on the floor and soil.
- Surface Suitability: Wood, concrete, stone, and tile floors may respond differently to the same pad. Always test on a small area before full-scale use.
- Maintenance & Safety: Use appropriate protective gear and follow the floor finish manufacturer’s recommendations for prep and finishing steps.
