Mirka GOLD 6" Grip P36 Sanding Discs, model 23-622-036, are 6 inch grip-backed abrasive discs built for fast, aggressive sanding and surface prep. This is a sanding disc designed for heavy material removal, stripping, and leveling across a wide range of shop and finishing materials. If you need an abrasive that cuts hard at the start of the job, this coarse P36 version is aimed at that kind of work.

Mirka describes the Gold line as a durable, multi-use abrasive for high-speed sanding, and that matters in real use. On a random orbit sander or other compatible 6 inch grip sanding setup, the coarse grit helps remove paint, flatten body filler, shape plaster and filler, and break down rough wood surfaces before moving into finer grits. The stated resistance to clogging and pilling is especially important in coating removal and filler sanding, where loaded paper slows the cut and forces more disc changes.

The 6 inch format is a common sweet spot for general sanding because it gives you enough coverage to move quickly without feeling oversized on broad prep work. The grip backing also keeps disc changes simple. When you're stepping through grits during refinishing, paint prep, or repair work, that quick on-off attachment saves time and keeps the process cleaner than fighting adhesive-backed paper.

This Mirka abrasive is positioned as a true multi-surface option. Based on the provided material list, it is suitable for copper alloys, brass, bronze, non-ferrous metal, paint stripping and removal, plaster, filler, glass fiber, synthetic materials, chipboard, veneer, plastics, primer, paint sanding, body filler, hardwood, soft or resinous wood, and lacquers. That wide material coverage makes it useful for body shop prep, woodworking, remodeling, and general finishing work where the substrate changes from one task to the next.

The coarse P36 grit is not a finish-ready disc, and that is the point. It is for the early stages where speed matters more than surface refinement. Use it when you need to remove material efficiently, then step into finer grits for smoothing and finish prep. If your job starts with rough stock, old coatings, heavy primer, or built-up filler, this is the kind of abrasive you reach for first.

Each pack includes 50 discs, which makes sense for production sanding and repeat prep work. Pros will appreciate having enough discs on hand for batch work, while serious DIY users get a box size that covers multiple projects without constantly reordering. If you already run a compatible 6 inch grip sander and want a dependable coarse abrasive for demanding prep work, this Mirka disc is the right kind of consumable to keep in the shop.
