3M 7000118311 Wetordry Abrasive Sheet 80 Grit

Product Description

The 3M 7000118311 is a silicon carbide Wetordry abrasive sheet designed for wet or dry sanding applications. Built on a flexible C-weight paper backing, this sheet delivers consistent cut and finish across a range of surfaces including metal, paint, primer, and composite materials. The 80-grit designation makes it appropriate for aggressive material removal and surface preparation before finer finishing stages. At 0.07 pounds per sheet, it is lightweight and easy to handle during hand or block sanding. Trade professionals in auto body, HVAC fabrication, and general metalworking rely on this sheet for reliable, repeatable results.

This abrasive sheet is suited for both wet and dry sanding operations, giving the technician flexibility depending on the substrate and finish requirements. Wet sanding helps control dust and extend sheet life on painted or primed surfaces. Dry sanding works well for raw metal prep and material removal. The 9 inches x 11 inches format fits standard sanding blocks and can be cut to size for detail work. It is commonly used in professional shop environments and field service where surface prep is required before coating or assembly.
