Hands Down the Best Habd Sanders, Period.
Having 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! LolBut 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.

Great to use for clean crisp drywall corners
The beveled side is a must to use on inside corners when drywalling. The long flat side is great for feathered joints too. Make sure to use eye protection & a respirator.

Gets the job done
Works great for sanding drywall. I mainly use the sanding sponges on the inside corners. The larger ones allow for a better grip. Did not hold up as well as expected but made it through a fairly large job
Thea Slimp –
Great sander with lots of surface area
This was great to use, we had to blend new drywall into textured walls. Essentially had to make everything flat and this tool really was essential. I’m going to buy another one! I like the square corner edge and angled edge.

Works far better than the flat disk sander. Easily gets into corners. Perfect for drywall
Jul’s –
Good product. It is another tool that it goes into your toolbox. However, the 45 degree angle gives us a better access to an adjacent surface but make sure you use another tool to finish your sanding with a rigid sand paper to avoid any waving onto your final product.I do recommand.

Worked perfectly for a drywall project on the corners and smaller flat areas.
