3M 7100027106 Wetordry Abrasive Sheet 320 Grit

Product Description

The 3M 7100027106 is a silicon carbide Wetordry abrasive sheet built for fine sanding and surface finishing tasks. Mounted on a C-weight paper backing, the sheet delivers consistent cut and surface contact across flat and contoured work areas. At 320 grit, it is suited for smoothing between finish coats, light paint preparation, and final-stage material removal. The sheet measures 9 inches by 11 inches, a standard size that fits most hand-sanding blocks and can be cut to size for detail work. It runs wet or dry, giving the installer flexibility based on material type and desired finish quality. Trade professionals in HVAC, plumbing, and general finishing applications reach for this sheet when prep work demands a controlled, fine abrasive.

This abrasive sheet is used across a wide range of professional trade applications including metal surface preparation, fiberglass finishing, primer scuffing, and lacquer or paint smoothing. It is well suited for residential and light commercial work where a fine, consistent scratch pattern is required before applying a final coating or sealant. The wet sanding capability makes it practical for applications where dust control is a priority or where the workpiece benefits from lubricated cutting action to reduce loading and heat buildup.
