3M 7000118315 Wetordry Abrasive Sheet 150 Grit

Product Description

The 3M 7000118315 is a silicon carbide Wetordry abrasive sheet designed for wet or dry sanding applications in trade and finishing work. Built on a C-weight paper backing, this sheet delivers consistent cut and finish performance across a range of surfaces. At 150 grit, it sits in the medium-fine range, suitable for smoothing, scuff sanding, and surface preparation before priming or coating. The 9-inch by 11-inch sheet size is the standard format compatible with most hand-sanding blocks and manual finishing setups. Silicon carbide abrasive cuts aggressively on harder surfaces and breaks down predictably for a consistent finish.

This abrasive sheet is used across automotive refinishing, metal prep, fiberglass work, and general surface conditioning in trade environments. Its wet-or-dry construction makes it practical for applications where water or lubricant is used to reduce loading and extend sheet life. Plumbers, body shop techs, and general contractors reach for this format when hand sanding pipes, fittings, panels, or substrate surfaces prior to bonding or coating. The 9-inch by 11-inch format can be cut or folded to fit smaller work areas as needed.

Key Features

• Silicon carbide abrasive mineral for consistent cut on hard surfaces and composites
• 150 grit rating for medium-fine material removal and surface prep
• C-weight paper backing balances flexibility and tear resistance for hand sanding
• Wet or dry use — compatible with water, oil, or solvent lubricants
• Standard 9-inch by 11-inch sheet size fits most hand blocks and can be hand-cut to size

Compatibility

Designed as a general-purpose abrasive sheet for hand sanding applications across metal, fiberglass, primers, and hard surface finishing tasks where a 9-inch by 11-inch C-weight sheet is specified.

Installation Notes

No installation required. When used wet, ensure the work surface and surrounding area are appropriate for water or lubricant exposure. Fold or cut the sheet to fit sanding blocks using a straight edge and utility knife. Wear appropriate PPE including gloves and eye protection when sanding — especially on metals, composites, or coated surfaces that may generate fine particulate.
