3M 7100113705 Large Area Sanding Sponge Fine Medium Grit

Product Description

The 3M 7100113705 is a dual-grit large area sanding sponge designed for both dry and wet sanding applications across a wide range of surfaces including wood, paint, metal, plastic, and drywall. It features two abrasive grades — fine and medium — on a single sponge body, reducing the need to switch between tools mid-job. Measuring 4.875 inches by 2.875 inches by 1 inch, the sponge is sized for one-hand control on flat and contoured surfaces. After use, the sponge can be rinsed clean and reused, making it a practical choice for ongoing finish work and prep tasks.

This sanding sponge is suited for residential and light commercial finishing work. Typical applications include surface prep before painting or coating, feathering drywall compound, scuff sanding between finish coats on wood or metal, and removing light oxidation or surface contamination from plastic components. Its dual-grit format makes it especially efficient for situations where a tech or finisher needs to step through two grit stages without reaching for separate abrasives. Sold individually, with a minimum order quantity of 10 units.

Installation Notes

Sanding sponges of this type are typically used by painters, drywall finishers, and general contractors during surface prep and finish coat stages. No power tools or special equipment are required. When wet sanding, keep the sponge damp but not saturated, and rinse thoroughly after each use to clear abrasive loading. Dispose of the sponge when abrasive surfaces no longer cut effectively.
