Progress through 100 → 200 → 400 → 800 → 1500 → 3000 grit. Wet polishing pads\n  with water feed give best results on granite. Keep RPM at 3,000-4,500.

Start at 100 grit to remove scratches and etching, then progress 200 → 400 → 800\n  → 1500 → 3000 grit. Always use wet polishing for marble — dry heat can cause thermal shock. Light pressure only.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use diamond polishing pads on marble?\u003c\/h3\u003e\n\u003cp\u003eBegin with 100 or 200 grit on marble (skip 50 unless there is severe damage). Marble is softer than granite — use lighter pressure.\n  White resin bond pads prevent gray discoloration on Carrara, Calacatta, and Thassos marble.\u003c\/p\u003e\n\n\u003ch3\u003eWhat polishing pad should be used to polish granite countertops?\u003c\/h3\u003e\n\u003cp\u003eFor granite countertops, use resin bond wet diamond polishing pads with hook \u0026amp; loop backing.
