Product Description
Product Description
3M Sanding Sponges are designed for sanding wood, paint, metal, plastic or drywall. This sponge features conventional 3M abrasives and is made with durable, flexible foam. The block shape makes it easy to hold and sands flat, contoured, or irregular surfaces. Sanding is an integral step in preparing a surface to receive a coating. For the best sanding results, sand with the grain of the surface and work through a sequence of grits, from coarse to very fine, skipping no more than one grit between each sanding step.
From the Manufacturer
For either dry or wet sanding. Ideal for sanding wood, paint, plastic and drywall. Rinse and reuse.

- Reviewed in the United States on September 2, 2018Having a LONG history with all products 3M, I have to say there TRULY are the cremede la creme of every single product they make. Have you EVER had a sub-par 3M item?? No you haven’t! From their excellent products to their quality control, you NEVER get a substandard product. The world would be a better place if 3M manufactured everything! Lol
But all joking aside, these sanding sponges are the best I’ve ever used, bar none! They last longer, perform better, and are not that much more pricey than “entry level” products. Why pay the same or more, for less?
Get these to replace whatever you’re currently using, and you will never look at another company again. Seriously.

5.0 out of 5 stars Decent drywall sander
Works far better than the flat disk sander. Easily gets into corners. Perfect for drywall
