3M 7100048572 Silicon Carbide Sheet 400 Grit 3-2/3x9 in

Product Description

The 3M 7100048572 is a silicon carbide abrasive sheet designed for fine finishing and surface preparation tasks. Built on an A-weight light paper backing, this sheet delivers consistent cut and finish on a range of substrates. The load-resistant coating helps prevent premature glazing during use, extending the working life of each sheet. At 400 grit, it is suited for final-stage sanding, light stock removal, and between-coat scuffing on wood, metal, plastic, and painted surfaces. Trade professionals in finishing, fabrication, and surface prep rely on this sheet for controlled, repeatable results.

This abrasive sheet is used in hand-sanding applications across automotive refinishing, woodworking, metalworking, and general surface preparation. Its 3-2/3 inch by 9 inch format fits standard hand-sanding blocks and is compatible with manual sheet-folding techniques common in finishing trades. The 400-grit silicon carbide mineral provides a fine scratch pattern appropriate for pre-polish prep, sealer scuffing, and final finish work on both hard and soft materials.
