Diamonds aren't just for jewelry. They're the key to professional stone restoration. Here's the science behind our process.
How We Use Diamond Abrasives to Restore Stone The "secret" behind professional stone restoration? Industrial diamonds. Here's how they work. Why Diamonds? Diamond is the hardest natural material on Earth (10 on the Mohs scale). This means diamond abrasives can: - Cut through any natural stone - Create precise, controlled surface removal - Produce progressively finer finishes - Last longer than any other abrasive material The Grit Progression We use a sequence of diamond pads, each finer than the last: Coarse (50-100 grit) Purpose: Remove deep damage - Eliminates deep scratches and stains - Levels lippage between tiles - Removes old coatings and buildup - Aggressive material removal Medium (200-400 grit) Purpose: Refine and smooth - Removes marks left by coarse grinding - Begins smoothing the surface - Prepares for honing Fine (800-1500 grit) Purpose: Honing - Creates a smooth, matte surface - Removes all visible scratches - The stopping point for honed finishes Ultra-Fine (3000+ grit) Purpose: Polishing - Creates high-gloss mirror finish - Closes surface pores - Produces maximum light reflection - Creates the "wow" factor Types of Diamond Tools We Use Floor Machines Weighted machines that hold multiple diamond pads. These cover large areas efficiently and evenly. Hand Polishers For countertops, edges, and detailed work. These allow precision in tight spaces. Diamond Brushes For textured surfaces where flat pads can't reach into grooves. Diamond Cups For aggressive grinding on
