Resin and metal bond polishing pads serve different stages of the stone and concrete finishing process.
Stone and concrete polishing progresses through multiple grit stages, each requiring the correct bond type to achieve the target surface finish efficiently. Resin bond pads dominate fine polishing stages; metal bond pads handle heavy grinding and lippage removal. Protec Tools offers both bond types in color-coded grit sequences for fabrication shops and flooring contractors.
Metal Bond Pads
Metal bond pads use a sintered or electroplated metal matrix that resists wear during aggressive stock removal. They flatten lippage, remove epoxy coatings, and prepare surfaces for resin pad sequences.
- Grit range: Typically 16–200 for grinding and honing passes.
- Best for: Initial lippage removal on granite and concrete floors.
- Limitation: Leaves visible scratches if used as final finish without resin follow-up.
Resin Bond Pads
Resin bond pads provide a cushioned cutting action that produces higher gloss levels on stone and densified concrete. They dominate the 400–3000 grit finishing range.
Sequence Best Practice
- Start with metal bond for stock removal and lippage leveling.
- Transition to resin bond at 200 grit — do not skip more than one grit step.
- Complete with 1500–3000 grit resin for mirror finish on granite.
- Replace pads when cutting action stops; continuing wastes labor and overheats the surface.
