This is a \u003cstrong\u003ePSA sanding disc roll designed for finish sanding and polishing\u003c\/strong\u003e. Model Number: \u003cstrong\u003e23-314-400\u003c\/strong\u003e. If you need a finer grit for smoothing surfaces before final finishing, this is the kind of abrasive that belongs in the drawer instead of a coarser prep disc.\u003c\/p\u003e\n      \u003cp\u003eThe P400 grit puts this Mirka sanding disc firmly in the finishing range. That makes it a practical choice when the job has already been shaped and leveled, and now you need to refine the surface, reduce visible scratch patterns, or prep for the next coating or polishing step. It is not meant for aggressive removal. It is meant for controlled, lighter sanding where consistency matters.\u003c\/p\u003e\n      \u003cp\u003eMirka uses aluminum oxide abrasive here, which is a proven material for general-purpose sanding. In real use, that matters because it gives you a reliable cut without turning this into a specialty-only disc. The source data also calls out a coated construction, a semi-open coating, and a special stearate treatment intended to reduce clogging and pilling. That is the kind of detail that helps when you are sanding finer material and do not want the disc loading up too quickly.\u003c\/p\u003e\n      \u003cp\u003eThe PSA backing is the other big reason to buy this product. Pressure-sensitive adhesive discs are straightforward: peel, stick, sand, replace. For users doing repeated changeouts, that can be faster and cleaner than messing with other attachment styles when the tool or pad setup is already built around PSA. If your workflow depends on quick disc swaps and a flat, secure hold, PSA still gets the job done.\u003c\/p\u003e\n      \u003cp\u003eAt 5 inches in diameter, this size fits a common sanding format used in many finishing and surface-prep setups. The roll format is also practical. Instead of dealing with loose discs sliding around the bench, the discs stay organized and easier to grab during repetitive work. For a shop that goes through fine grit abrasives regularly, that is a simple but real convenience.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka abrasive is best suited for painters, body shop users, finish carpenters, woodworkers, and serious DIYers who already know where a P400 disc fits in the sanding sequence. If you are doing final surface prep, refining between coats, or polishing-related sanding steps, this grit makes sense. If you need heavy removal, skip this and move coarser. If you need a clean finishing step with a trusted abrasive brand, this is the right lane.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eStay Consistent on Finish Work\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260624710_1.jpg\" alt=\"Mirka 23-314-400 PSA Disc Roll 5 in P400 PK100 fine sanding discs in roll form for finish sanding and polishing in a shop setting\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eFine-grit sanding is where cheap abrasives start wasting your time.
