Buying Guide
Grit Range and Progression
Choose grit progression that matches your project. Coarser grits remove heavy material quickly, while finer grits produce high-gloss finishes. For concrete floors, a typical progression starts at around 50 or 100, then moves through 200, 400, 800, 1500, 3000 and beyond for bright polish. For countertops, a tighter finish usually starts at 100 and moves to 400, 800, 1500 and 3000. Ensure your kit includes a complete range or plan to buy individual grits to fill gaps.
Wet vs Dry Polishing
Wet polishing reduces dust and helps control heat, which improves surface gloss and prolongs pad life. Dry polishing can be convenient but may generate more dust and heat, potentially causing uneven finishes. Many diamond pad sets are designed for both methods, but always consult the user manual and never exceed recommended RPM for dry polishing on delicate surfaces.
Backing Type and Compatibility
Backing systems affect pad attachment and ease of change. Hook-and-loop backs are common and allow quick interchange on many grinders. Some kits include backing pads or holder accessories to simplify mounting. Confirm your grinder’s thread size (for example 5/8”-11) and ensure compatibility with the backing system to avoid slippage and damage during polishing.
Pad Size and Tool Compatibility
Pad diameter should match your machine’s polishing head. The most common sizes are 4 and 5 inches. Larger pads cover more area but require more powerful equipment and careful handling to avoid gouges. Consider your machine’s speed range and whether you will polish floors, countertops, or vertical walls to determine the best pad size and grit sequence.
Maintenance and Safety
Clean pads after use to remove resin buildup. Store in a dry place away from direct sun to prevent pad degradation. When polishing, wear eye protection, a dust mask, and hearing protection if using loud grinders. Inspect pads for cracks or chunking and replace worn pads promptly to prevent damage to the workpiece.
