DiamaPro 5“ Wet/Dry Honeycomb Pad, 400 grit

- Mid-grit resin polishing pad for the refinement stage — 400 grit sits in the middle of the resin polishing sequence, used after coarser resin pads (50, 100, 200) have removed the metal-bond scratch pattern and started building the surface refinement. Begins to develop visible sheen and prepares the floor for the final gloss-building steps. Part of DiamaPro Systems' resin polishing pad line, calibrated for cutting speed and tool life.

- Smaller 5" footprint for tight-area and detail polishing — the 5" diameter is sized for narrow edges, around columns and obstructions, on stair treads, in corners, and anywhere a 7" pad is too bulky to maneuver. The smaller pad is also easier to control on overhead work and detail polishing where operator fatigue from a heavier 7" pad becomes an issue. Choose 5" for precision work; choose 7" for production speed on open floors.

- Flexible honeycomb resin design for even pressure and dust evacuation — the hexagonal pattern molded into the pad's face creates large channels that evacuate dust during dry use and water during wet use, preventing the diamond surface from loading up. The honeycomb structure also flexes around contours and lippage, maintaining consistent contact pressure across the entire pad face — important for an even sheen as the surface transitions toward high gloss.

- Wet/Dry dual-mode operation — usable in either condition: wet polishing reduces heat and extends pad life, dry polishing is more convenient on job sites without water access. Note: a 5" backing pad with hook-and-loop attachment is required to mount this pad to a 5" hand polisher (like the DiamaPro HGP-5). Do not run a 5" pad on a 7" backer — the size mismatch creates unsafe exposed hook-and-loop edges at high RPM.

- The revitalization step for worn polished edges — per industry guidance, 400 grit is also the recommended starting point when restoring scuffed or worn polished concrete that doesn't need full re-grinding. On a 5" pad specifically, this is the go-to grit for cleaning up edge polish that's degraded faster than the main floor — the pad cuts enough to remove scuffs and surface haze without dropping back to the metal-bond stage. The "fix without re-grinding" pad for the perimeter and detail areas.
