3M 7100160821 Sanding Screen 100 Grit 17 Inches

Product Description

The 3M 7100160821 is a 17-inch diameter sanding screen designed for material removal and surface preparation on hard and semi-hard surfaces. Built with a silicone carbide abrasive bonded in resin, this medium-grit screen delivers consistent cutting action across concrete, marble, stone, wood, and urethane finishes. The open-mesh construction allows dust to pass through rather than load the screen, extending usable life compared to solid abrasive pads. At 100 grit, it sits in the medium range, making it suitable for initial smoothing passes as well as light stock removal on finish flooring and surface restoration projects. Weighing 2.5 pounds per package, it ships as a single-count unit.

This sanding screen is intended for use with rotary floor machines in commercial and residential settings. Floor care professionals, concrete finishing crews, and flooring installers use it to prepare and refinish surfaces before applying sealers, coatings, or finish layers. Typical applications include scuff-sanding urethane-coated hardwood floors, cleaning and abrading stone or marble surfaces, and opening up concrete for coating adhesion. The 17-inch diameter fits standard floor buffer pads and drive plates used in professional floor maintenance equipment.

Installation Notes

Installation and use should be performed by a flooring professional or trained floor care technician. Before use, ensure the floor machine is powered off and unplugged while mounting the screen to the drive plate or backing pad. Inspect the screen for tears or damage before each pass, as a compromised screen can snag on surface irregularities. Follow equipment manufacturer guidelines for machine speed and downward pressure appropriate to the surface being worked.
