Mirka 6-in. 180 Grit PSA Sanding Disc with C-Weight Backing (23-342-180)

The Mirka 23 Series Gold 6 in PSA Linkrol Disc, 180-Grit, C-Weight Backing is a sanding disc for power sanders built for general-purpose finishing work. This is a sanding disc designed for dry sanding primer, lacquer, and similar surface prep applications. Model number 23-342-180. If you need an abrasive that can handle production sanding without loading up too quickly, this one is aimed right at that job.

What matters here is the balance between cut and finish. At 180 grit, this Mirka sanding disc is suited to finer sanding steps where you are smoothing surfaces and preparing them for the next stage, not aggressively stripping heavy material. The source data also notes that finer grits are suitable for dry sanding surfaces with primer and lacquer, which makes this a practical choice for finish prep, repaint work, and shop sanding where consistency matters.

Mirka’s Gold abrasive line is known as an all-around sanding material, and that shows in the way this disc is positioned. It is described as durable and well suited for sanding at high speeds, which is important if you are running a power sander for longer passes and do not want the abrasive to give up halfway through the job. A sanding disc that holds together and keeps cutting saves time, especially on repeated prep work.

The semi-open grit binding and special stearate coating are the details that make this product more useful in real work. Those features are meant to prevent clogging and pill forming, which helps the abrasive stay cleaner as dust and finish residue build up. In plain terms, that means less wasted paper, less frustration, and a more even sanding pattern over the life of the disc.

The 6 inch size fits the common workflow for random orbit sanding and other power sanding tasks where broad, even surface contact matters. The PSA Linkrol format gives you a pressure-sensitive adhesive style attachment, which is useful when you want a secure hold during sanding and a straightforward disc change when it is time to swap grits.

This Mirka 23 Series Gold 6 in PSA Linkrol Disc, 180-Grit, C-Weight Backing makes the most sense for body shops, finish carpentry prep, cabinet work, paint prep, and serious DIY users who care about surface quality. If your sanding jobs involve primer, lacquer, or other finishing layers and you want a dependable abrasive instead of the cheapest option on the rack, this is the kind of disc worth using.
