Mirka 2-3/4-in. x 16-1/2-in. 36 Grit PSA File Sanding Sheet, Gold (23-364-036)

The Mirka 23-364-036 PSA File Sheet is a sanding sheet designed for aggressive material removal on long sanding tools and file boards. This is a sanding sheet designed for coarse sanding, stripping, and leveling work. Model Number 23-364-036. With a 36 grit rating and a 2-3/4 in x 16-1/2 in size, it is aimed at users who need a long abrasive sheet that cuts fast instead of loading up a tool with a grit that is too fine for the job.

What matters most here is the grit. A 36 grit abrasive is not for finish sanding. It is for the early stage of the job, when you need to remove material quickly, knock down high spots, or strip a surface before moving through finer grits. If you are shaping filler, leveling rough stock, or cleaning up a surface before the next sanding step, this coarse sanding sheet makes more sense than trying to force a medium grit to do heavy removal.

The sheet format also matters. At 2-3/4 inches wide and 16-1/2 inches long, this Mirka abrasive is built for tools and sanding setups that use a longer file-style sheet. That longer footprint helps spread pressure across more of the work surface, which can make it easier to keep a panel or workpiece flatter during sanding. For users working on broad areas or long passes, that is a practical advantage over smaller sheet formats.

The product name identifies it as a PSA file sheet, which means it uses a pressure-sensitive adhesive style attachment. That setup is useful when you want the sheet to stay planted on the sanding surface without shifting around during aggressive passes. On jobs where you are leaning into the cut and trying to move material quickly, secure attachment is part of getting consistent results.

Mirka is well known for abrasives, and this product sits in the category where abrasive choice directly affects speed and finish quality. A coarse sheet like this is about getting through the rough stage efficiently so you can move on to refinement with the right follow-up grit. Used in the proper sanding sequence, it helps cut down the time spent fighting a surface that still needs major correction.

Who should buy it? This Mirka sanding sheet makes sense for users who already run a compatible file-style sanding setup and know they need an extra coarse sheet for rapid removal. It is best suited to bodywork, surface prep, rough shaping, and any sanding process that starts with serious cut before moving into finer finishing steps. If you need finish-ready results from one sheet, this is not the right grit. If you need to remove material fast and move the job forward, it is doing exactly what it should.
