Mirka 24-38P-150 Iridium 2.75" x 16" Perforated Strips 150G is a premium sanding strip for finish sanding and material removal across wood, metal, automotive refinishing, and industrial surface prep. This is a sanding strip designed for dust-controlled surface preparation and finishing. Model Number: 24-38P-150. If you need a strip that cuts aggressively without loading up early, this is the kind of abrasive that earns its keep.

The big story here is the abrasive itself. Mirka uses a ceramic and aluminum oxide grain blend that gives the strip a hard initial bite, then keeps the scratch pattern even as you work. That matters when you are trying to move fast but still need a predictable finish before primer, paint, stain, or final coating. In 150 grit, it lands in a useful middle ground for smoothing, blending, and refining surfaces without being overly coarse.

Dust management is another real advantage. These Iridium strips use an optimized multihole perforation pattern that helps pull dust away from the work surface. Less dust sitting under the strip means less clogging, more consistent cutting, and less time wasting sheets that quit early. On finish work, that also helps reduce random deep scratches caused by packed debris.

Mirka also built these strips for real shop use, not one-pass throwaways. The backing is listed as latex C-paper, which gives the strip flexibility, while the low VOC resin bonding system is designed for strong grain adhesion. In plain terms, the abrasive stays put better, including when the strip is folded or worked hard around edges and profiles. That helps the strip last longer and keeps the cut more consistent over its service life.

The 2.75 in x 16 in format fits long sanding applications, and the center perforation gives you another option: tear the strip to fit 2.75 in x 8 in sanders. That kind of flexibility is useful if you run more than one sander size in the shop or want to stock one strip that can cover multiple setups. No alignment of the strips is required, which makes changeover simpler and keeps you moving.

Mirka positions these strips for automotive refinishing, wood processing, metal processing, marine work, and vehicle manufacturing, and that lines up with the spec sheet. If you are sanding body filler, leveling primer, refining wood surfaces, or cleaning up fabricated metal before finishing, this abrasive makes sense. It is a good fit for pros who care about cut speed, dust extraction, and consistent finish quality, and it is also a smart upgrade for serious DIY users who are tired of sanding sheets that load up too fast.
