The Mirka Iridium 3x5 Grip 54H 240 Sandpaper Sheets, model 24-35M-240, are fine-grit sanding sheets for users who need clean surface prep and dependable attachment on compatible finish sanders. This is a sandpaper sheet designed for fine sanding and finish preparation. If you are working through paint prep, between-coat sanding, light refinishing, or final smoothing before finish, this size and grit land in a very practical spot.

The 240 grit matters because it gives you more control during the refinement stage. Instead of removing material aggressively, it helps smooth scratches left by coarser abrasives and gets surfaces ready for the next step. That makes it a good fit for wood finishing, filler feathering, primer prep, and other sanding work where surface quality is the whole point.

The 3 x 5 inch format is built for smaller finish sanders that use this sheet size, and the grip backing means quick changeovers without messing with clamps. On the job, that saves time when you are stepping through grit changes or replacing a loaded sheet before it starts dragging the finish quality down.

The 54-hole pattern is there for dust extraction on compatible sanding platforms. Better dust pull means the abrasive face stays clearer, the sheet keeps cutting more consistently, and you spend less time fighting buildup. That is especially useful on painted surfaces, primers, and fine dust applications where clogging can kill performance fast.

This Mirka sanding abrasive is sold in a 50-pack, which makes sense for shops and contractors who burn through consumables regularly. Instead of buying a few sheets at a time, you are set up with enough stock to keep production moving through prep and finish stages without constantly reordering.

If you already run compatible hook-and-loop finish sanders and want a fine sanding sheet for controlled surface prep, this is the kind of consumable that earns its keep. It is a straightforward fit for woodworkers, painters, refinishers, cabinet installers, and serious DIY users who care more about surface quality than brute stock removal.
