3M 7000118312 Wetordry Abrasive Sheet 100 Grit 9x11 in

Product Description

The 3M 7000118312 is a silicon carbide Wetordry abrasive sheet designed for wet or dry sanding applications. Built on a C-weight paper backing, it delivers consistent cut and finish across a wide range of surfaces. The 100-grit rating makes it suitable for intermediate material removal and surface prep work where a moderate scratch pattern is needed before finer finishing passes. Each sheet measures 9 inches x 11 inches, fitting standard hand-block and machine sanding setups. Tradespeople and finishing specialists use this sheet when working on metal, fiberglass, primer coats, and similar substrates that require controlled abrasion without aggressive stock removal.

This abrasive sheet is used across automotive refinishing, bodywork prep, metal fabrication, and general industrial surface preparation. It performs equally in wet and dry conditions, making it a practical choice when water or lubricant is needed to reduce loading or manage surface heat. The 9 x 11 inch format is a standard size that folds or cuts easily to fit sanding blocks, orbital backing pads, or hand-sanding applications common in body shops, manufacturing environments, and trade finishing work.

Key Features

• Silicon carbide abrasive mineral for sharp, consistent cut on hard surfaces
• C-weight paper backing provides flexibility with adequate support for hand and block sanding
• Rated at 100 grit for intermediate surface prep and scratch refinement
• Runs wet or dry, reducing loading and extending sheet life in wet applications
• Standard 9 inches x 11 inches sheet size fits common sanding blocks and backing pads

Compatibility

Designed as an OEM-style replacement abrasive sheet for general wet or dry hand-sanding and block-sanding applications across automotive, metalworking, and industrial finishing workflows.

Installation Notes

This product is installed by hand or fitted to a sanding block or backing pad — no power tools or special equipment required. When sanding wet, ensure surrounding electrical components and surfaces sensitive to moisture are protected. Fold or cut to size as needed using standard shop scissors or a straight edge. Replace the sheet when abrasive loading or glazing reduces cut efficiency.
