The Ultimate Choice for Surface Preparation Hand Finishing

This ultra-flexible and conformable non-woven abrasive roll is the perfect solution for cleaning or fine finishing. The Scotch-Brite™ Multi-Flex Sheet is a great replacement for steel wool and eliminates contaminants.

The ultra-fine grade silicon carbide abrasive mineral is suitable for cleaning and finishing surfaces by hand in woodworking, metalworking, synthetics fabrication, and maintenance operations.

The Scotch-Brite™ Multi-Flex Sheet comes in three grades, each offering a different level of aggressiveness for cutting and finishing:

  • Most Aggressive – High Cut for Paint Prep and Wood
    The purple grade is highly conformable and offers a high cut for paint preparation and wood finishes without dumping edges. It is ideal for scuffing new panels, door jambs, and under bonnet areas. It is also great for scuffing prior to primer and paint for proper mechanical adhesion, for tire clean-up, and for cleaning grease, oil, and rust from engine and other mechanical parts.
  • Less Aggressive – For Exceptional Finishes on Wood and Metal
    The grey Multi-Flex Sheets are perfect for preparing color coat and simple blending and can be used with 3M™ Prep and Blend Liquid (09308) or degreaser. Use these, as well, for light scuffing of primer and paint.
  • Least Aggressive – For Cleaning and Fine Finishing
    The copper grade is the least aggressive and is used for water-based paint systems and critical color blending. Use it for light scouring and with 3M™ Prep and Blend Liquid (09308) or degreaser.
