Buying Guide

Match pad type to process

Choose wet diamond pads for continuous, high-gloss concrete polishing and dry pads for quick touch-ups or areas where water use is restricted

Select correct pad diameter

Use 4" pads for grinders and tight spaces, 6–7" pads for larger polishers to balance coverage and control during concrete polishing

Grit progression matters

Follow a multi-step grit sequence (coarse to fine, e.g., 50 up through resin-bond finer grits) to remove surface defects and build shine without overworking the slab

Consider pad bonding and material

Diamond-segment and resin-based pads perform differently on concrete and stone—resin bonds often yield higher gloss on polished concrete while bonded segments are better for heavy material removal

Value vs. longevity

Multi-pack options can lower cost per pad, but higher-rated diamond pads typically last longer under professional loads, affecting lifetime cost
