3M 7100138727 Woodworking Sanding Sponge

Product Description

The 3M 7100138727 is a woodworking sanding sponge designed for material removal and surface finishing on flat and contoured workpieces. Measuring 3.75 inches x 4.75 inches x 0.5 inches and weighing 0.03 pounds, this sponge conforms to irregular profiles while maintaining abrasive contact across the entire surface. It is suited for use on wood, metal, plastic, and painted surfaces. Trades and finishing professionals reach for this sponge when sealing coats, finish coats, or prep work require consistent scratch patterns without the rigidity of a sanding block.

This sanding sponge is appropriate for both residential and light commercial finishing applications. It performs on flat panels, inside corners, coves, moldings, and other contoured surfaces where sheet sandpaper is difficult to control. Common use cases include between-coat sanding of sealers and topcoats on cabinetry, furniture, trim, and millwork, as well as light material removal on metal and plastic assemblies.

• Compact 3.75 inches x 4.75 inches x 0.5 inches profile fits comfortably in one hand

Compatibility

Designed as a general-purpose sanding sponge for woodworking, finishing, and surface preparation tasks on wood, metal, plastic, and painted surfaces.

Installation Notes

This sanding sponge is used by finish carpenters, cabinet makers, painters, and general tradespeople. Before sanding any coated surface, confirm the previous coat is fully cured per the coating manufacturer guidelines. Apply consistent, even hand pressure and sand with the grain on wood surfaces to avoid cross-grain scratches. Wear appropriate respiratory protection when sanding in enclosed spaces or when working with materials that generate hazardous dust.
