    Built for Durability and Ease of Use
    The 3M™ Stikit™ Blue Abrasive Disc Roll (PDF, 749 Kb) is bonded using upgraded resins for enhanced durability. An anti-loading coating across the abrasive surface helps keep dust from gathering between the abrasive grains for faster cut and consistent performance throughout the life of the disc.

    3M™ Blue Abrasives deliver consistently excellent results in a minimum amount of time on jobs ranging from aggressive paint removal and fresh filler sanding to blend preparation and sanding primer.
    These abrasives are recommended for use with 3M™ Stikit™ Disc Pads
    Our Stikit™ Attachment System
    3M™ Stikit™ Blue Abrasive Disc Rolls is packaged as multiple adhesive-backed discs rolled onto a core. These discs tear off conveniently one at a time for speed and efficiency and they require no liners which saves material costs. 3M™ Stikit™ discs come ready to use with a pressure sensitive adhesive coating on the backs — simply press the disc onto the backup pad and you're ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next disc. We recommend using Stikit™ discs with 3M™ Stikit™ Disc Pads. For best results, we recommend use with the 3M™ Stikit™ Disc Roll Dispenser PN 05450.
