SALI 4-inch 30G Diamond Polishing Pads 10-Pack — Wet Stone Grinding Pads for Granite, Marble, Quartz

These 4-inch pads combine industrial-grade diamond particles with a tough resin matrix to remove heavy scratches, level rough spots and prepare stone or concrete for finer polishing steps. Supplied with hook-and-loop backing, the kit installs quickly on drills, angle grinders, polishers and rotatory tools that accept a 4" pad, while water-assisted use reduces dust and extends pad life. The set contains 10 identical 30-grit discs so you have enough abrasive life for small renovation jobs or multiple touch-ups.

How do these pads perform on dense materials like granite or quartz?

SALI 30-grit pads are built for heavy material removal on dense surfaces. The coarse diamond grit cuts fast and consistently, exposing fresh stone for subsequent finer grits and reducing time spent on manual grinding.

• 30-grit diamond formulation for aggressive stock removal
• Durable resin bond that resists flaking under load
• Best used wet to minimize dust and improve cut rate
• Consistent wear pattern for predictable results

Which tools can I use these 4" pads with and how do I attach them?

The pads accept standard hook-and-loop attachment and fit most 4-inch backing plates, making them compatible with variable-speed polishers, angle grinders, handheld drills (with appropriate backing), and rotary tools. Always check your tool’s RPM rating and thread or backing size before installation.

• Hook-and-loop backing for fast installation and removal
• Use with variable-speed polishers, grinders, or drill adapters
• Confirm tool speed and use lower RPMs for wet polishing
• Keep constant water feed for cooling and cleaner cuts

What surfaces and project types are these pads suited for?

These pads are versatile across most solid-surface materials. They excel at renovating countertops, smoothing concrete, removing deep scratches from marble, and preparing terrazzo or vitrified tile for finishing steps.

• Granite, marble, quartz and engineered stone
• Concrete countertops, floors and patches
• Tiles, terrazzo and other natural stone surfaces
• Suitable for edge work, small flat areas, and detail repairs

How should I use and maintain the pads for best life and results?

Use these pads wet to reduce dust, cool the diamond surface and prolong usable life. Replace a pad when cutting efficiency drops or the resin bond is visibly worn; avoid dry grinding on hard stones to prevent premature failure.

• Run at recommended lower RPMs for wet sanding/polishing
• Keep steady water flow to flush debris and cool diamonds
• Rotate pads periodically to prevent glazing and uneven wear
• Store in a cool, dry place away from direct sunlight

Who this is for: Professionals, renovators and serious DIYers who need an economical, repeatable solution for heavy stock removal and surface preparation on stone and concrete. The SALI 10-pack gives contractors and homeowners enough coarse pads for countertop refinishing, patch preps, or multiple small jobs without constantly replacing single discs. If you require finishing grits after leveling, follow these 30-grit pads with progressively finer diamond pads to achieve the desired sheen.
