A \u003cstrong\u003elower grit number\u003c\/strong\u003e means a coarser abrasive — ideal for rapid material removal and initial shaping. A \u003cstrong\u003ehigher grit number\u003c\/strong\u003e produces a finer, smoother polish. Start coarse and work your way up to achieve that flawless, mirror-like finish on your stone or concrete surfaces.\u003c\/p\u003e\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDIY home renovation projects\u003c\/li\u003e\n  \u003cli\u003eProfessional stone fabricators and countertop installers\u003c\/li\u003e\n  \u003cli\u003eConcrete floor grinding and finishing\u003c\/li\u003e\n  \u003cli\u003eMarble restoration and polishing\u003c\/li\u003e\n  \u003cli\u003eGranite surface preparation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFor further guidance on safe use of abrasive tools and personal protective equipment, visit the OSHA Abrasive Wheel Machinery Safety Guidelines.\u003c\/p\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Angle_grinder\" target=\"_blank\" rel=\"noopener\"\u003eAngle grinder\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003eQ: What surfaces is this 80mm polishing pad backer compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This polishing pad backer is designed for use on a wide range of hard surfaces including granite, marble, concrete, quartz, and natural stone. Its silicon carbide and resin construction handles both wet and dry grinding applications on all of these materials.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What interface does this polishing pad backer use?\u003c\/h4\u003e\n\u003cp\u003eA: This pad backer features an \u003cstrong\u003eM10 spiral interface\u003c\/strong\u003e, which is the standard thread size used by most angle grinders and rotary polishing tools, making it easy to attach and swap out on commonly available equipment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I choose the right grit for my project?\u003c\/h4\u003e\n\u003cp\u003eA: For initial surface grinding, heavy material removal, or rough shaping, choose a \u003cstrong\u003elower grit number\u003c\/strong\u003e (coarser). For finishing, smoothing, and achieving a polished appearance, choose a \u003cstrong\u003ehigher grit number\u003c\/strong\u003e. For best results, work through progressively finer grits until you reach your desired surface finish.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this pad backer be used wet and dry?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — this pad backer is designed for both wet and dry use. Wet use with water helps keep the surface cool, reduces dust, and extends pad life.
