Tool Review: 3M Ultra Flexible Sanding Sheets
Ben Brunick takes a look at these contortionist sanding sheets
Rubbery and somewhat translucent, 3M Ultra Flexible Sanding Sheets excel at conforming to just about any profile. Available in grits of 100, 150, 220, and 320, it’s the only sanding sheet I’ve ever used that actually stretches, refusing to tear. It can be crumpled as tight as you want during use and then it returns to its original flat state.
Although this flexibility is its main attraction, the sandpaper also shines when used with a sanding block, where it refuses to tear when easing sharp corners and edges. That, along with its non-clogging characteristics, means it needs to be changed only when its grit finally gives up the ghost.
These assets can at times be liabilities. Because it doesn’t hold a crease, it tends to roll when sanding without a backer. Also, its rubbery backing can overheat if pushed too hard during high-speed sanding sessions at the lathe. It has certainly earned a spot on my shelf.
