    • Sanding Discs & Paper

    Professional Stone Surface Preparation & Finishing Abrasives

    Sanding Discs & Sandpaper

    Prepare, smooth, and refine granite, marble, and natural stone with professional sanding discs and abrasive sandpaper from BB Industries. Designed for scratch removal, edge shaping, surface preparation, and finish refinement, these abrasives bridge the gap between aggressive diamond grinding and final polishing. Available in silicon carbide and aluminum oxide formulations, they deliver consistent results for fabrication shops, installers, restoration professionals, and stone artisans.

    Silicon Carbide Sandpaper

    Silicon carbide abrasives provide fast, consistent cutting on granite and other hard natural stones. They are the preferred choice for scratch removal, edge refinement, and surface preparation before polishing.

    Multiple Attachment Styles

    Choose from hook-and-loop (Velcro®), PSA (pressure-sensitive adhesive), and other attachment systems to match your sanding equipment. Hook-and-loop discs are ideal for frequent grit changes during fabrication.

    Surface Preparation

    Sanding discs are commonly used to remove tool marks, smooth repaired areas, prepare stone for sealers, refine countertop edges, and hand-finish detailed areas that larger grinders cannot easily access.

    Professional Abrasive Brands

    BB Industries carries premium abrasives from Hermes, Alpha, Scorpion, and Starcke, providing dependable performance for fabrication shops, installers, restoration professionals, and decorative stone artisans.

    Choosing the Right Sandpaper for Stone

    Selecting the correct abrasive depends on the hardness of the material and the amount of stock removal required. Progressing through the proper grit sequence is essential for achieving a smooth finish without leaving deep scratches beneath finer abrasives.

    • 60-120 grit: Remove heavy scratches, tool marks, and perform initial shaping.
    • 220-400 grit: Refine the surface and prepare for polishing.
    • 600-1000 grit: Produce a smooth pre-polish finish and final hand refinement.
    • Material selection: Silicon carbide is recommended for granite and other hard stones, while aluminum oxide works well for many general sanding applications.

    Frequently Asked Questions

    What sandpaper should I use for polishing granite?

    Silicon carbide sandpaper in grits from approximately 220 through 1000 is commonly used for granite edge finishing and surface preparation. While sandpaper works well for detail work and hand finishing, diamond polishing pads remain the preferred solution for full-surface polishing because they cut faster and last significantly longer.

    What is the difference between hook-and-loop and PSA sandpaper?

    Hook-and-loop (Velcro®) sandpaper attaches quickly to a compatible back-up pad and allows rapid grit changes during polishing. PSA (pressure-sensitive adhesive) discs adhere directly to the backing pad and must be peeled away for replacement. Hook-and-loop systems are generally preferred for professional fabrication because they allow faster workflow.

    When should I use sanding discs instead of diamond polishing pads?

    Sanding discs are ideal for removing scratches, smoothing repairs, preparing surfaces for sealers, and refining edge profiles before polishing. Diamond polishing pads are better suited for achieving high-gloss finishes and completing the final polishing stages on granite, marble, quartz, and other natural stone.

    Can sanding discs be used for hand finishing?

    Yes. Sandpaper is commonly used by hand to finish inside corners, decorative edges, repaired areas, small stone pieces, and other detailed locations where powered polishing tools cannot easily reach.

    Why is grit progression important when sanding stone?

    Each grit should remove the scratch pattern left by the previous abrasive. Skipping grit levels often leaves deeper scratches hidden beneath finer finishes, making them visible after polishing. Working through the proper grit sequence produces a smoother, more consistent finished surface.
