The Mirka 23-352-180 Gold 8 in. PSA Sanding Disc 180 Grit is a pressure-sensitive adhesive sanding disc made for finish sanding and surface prep. This is a sanding disc designed for fine sanding, smoothing, and prep work on broad surfaces. Model Number: 23-352-180. If you need a disc that gives you consistent cut, clean adhesion to a PSA backup pad, and enough durability for repeated use, this one is aimed squarely at that job.

At 180 grit, this disc sits in the range where surface quality matters more than aggressive removal. It is a practical choice for refining wood, leveling primer, or cleaning up a surface before the next finishing step. The 8 inch diameter gives you wide coverage, which helps on larger workpieces where smaller discs slow you down.

Mirka's Gold abrasive line is known for combining steady cut with dependable finish quality, and the construction details here explain why. The resin bonding supports the abrasive grain so it stays working longer, while the special stearate coating is there to reduce clogging and loading. That matters because loaded discs stop cutting well and force you to either press harder or swap discs sooner than you should.

The backing also matters on a sanding disc, and this one uses a flexible C/D weight latex backing that balances toughness with enough give to stay useful on real surfaces. In plain terms, it is not so stiff that it fights the work, and not so flimsy that it falls apart early. That balance is a big part of why these discs are commonly chosen for general finish-sanding applications.

Because this is a PSA disc, it is meant to stick to a matching pressure-sensitive adhesive sanding pad rather than a hook and loop backup pad. That gives you a secure attachment and a flat interface, which is helpful when you want even contact across the face of the disc. If your sander or backup pad is set up for PSA discs, this is the right style of abrasive to keep on hand.

This Mirka sanding disc makes the most sense for users who need reliable fine-grit abrasives in box quantity, whether that is in a cabinet shop, paint prep workflow, fabrication environment, or a serious home shop. If your work depends on clean surface prep and repeatable finish quality, a 50-pack like this is the kind of consumable that earns its keep fast.
