Finishing Sheet, 400 Grit, Qty. 50\u003c\/strong\u003e is a finishing abrasive sheet pack built for surface prep and fine sanding. This is a finishing sheet designed for smoothing surfaces, refining previous sanding marks, and handling light prep work before final coating or polishing. Model Number: \u003cstrong\u003e20-101-400\u003c\/strong\u003e. If you need a practical sanding sheet for shop use, paint prep, or finish correction, this is the kind of consumable that earns its keep by cutting cleanly without driving up cost.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is the balance between finish quality and value. A 400 grit abrasive sits in the fine-sanding range, so it is useful when the goal is refinement rather than heavy stock removal. On the job, that means less risk of leaving deep scratch patterns that take extra time to clean up later. For anyone doing finish sanding by hand or using a sanding block, a 9 inch by 11 inch sheet is also a familiar size that is easy to fold, tear, or trim for the task at hand.\u003c\/p\u003e\n      \u003cp\u003eMirka describes the BaseCut line as an economical abrasive built with strong design, production processes, and materials. In plain terms, that means these finishing sheets are meant to give you a solid initial bite while still lasting long enough to keep sheet changes under control. That matters in real work because cheap abrasives often stop cutting early, load up fast, or force you to use more sheets than expected. A durable sanding sheet saves time even when the price per pack looks similar.\u003c\/p\u003e\n      \u003cp\u003eThis abrasive is suited for a wide variety of applications including wood and composites, and Mirka also calls out use on putty and lacquer removal. That gives it a broader range than a one-purpose sheet. In a cabinet shop, bodywork setting, or general repair workflow, that flexibility is useful because surface prep rarely stays limited to one material. You may be leveling filler on one pass, smoothing sealer on the next, and blending a finished wood surface after that.\u003c\/p\u003e\n      \u003cp\u003eThe 9 inch by 11 inch format also makes sense for users who want control. Full sheets are easy to use for hand sanding, and they can be cut down for detail work, edges, and smaller sanding blocks. For finish work, that control matters more than raw speed. You want even pressure, predictable scratch pattern, and enough sheet life to get through repetitive prep without wasting material.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka finishing sheet pack is a good fit for woodworkers, painters, refinishers, auto body users, and serious DIYers who go through abrasives regularly and want dependable results without stepping into a premium specialty sheet for every task. If your work involves fine sanding, surface correction, or final prep before coating, the Mirka 20-101-400 Base Cut 9 in. x 11 in. Finishing Sheet, 400 Grit, Qty. 50 is a smart shop staple to keep on hand.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"tnincluded-wrapper\"\u003e\n        \u003cul\u003e\n          \u003cli\u003e(50) Mirka Base Cut finishing sheets\u003c\/li\u003e\n          \u003cli\u003eSheet size: 9 in. x 11 in.\u003c\/li\u003e\n          \u003cli\u003eGrit: 400\u003c\/li\u003e\n        \u003c\/ul\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-key-specifications\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003ctable class=\"aplusspecs\"\u003e\n        \u003ctr\u003e\n          \u003cth\u003eProduct Type\u003c\/th\u003e\n          \u003ctd\u003eFinishing sheet\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eBrand\u003c\/th\u003e\n          \u003ctd\u003eMirka\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eModel Number\u003c\/th\u003e\n          \u003ctd\u003e20-101-400\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eSheet Size\u003c\/th\u003e\n          \u003ctd\u003e9 in. x 11 in.\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eGrit\u003c\/th\u003e\n          \u003ctd\u003e400\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eQuantity\u003c\/th\u003e\n          \u003ctd\u003e50 sheets\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eRecommended Materials\u003c\/th\u003e\n          \u003ctd\u003eWood, composites, putty, lacquer\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003cth\u003eApplication\u003c\/th\u003e\n          \u003ctd\u003eFine sanding and finishing\u003c\/td\u003e\n        \u003c\/tr\u003e\n      \u003c\/table\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-applications-uses\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt For\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"tags\"\u003e\n        \u003cspan class=\"tag\"\u003eWoodworking\u003c\/span\u003e\n        \u003cspan class=\"tag\"\u003ePainting\u003c\/span\u003e\n        \u003cspan class=\"tag\"\u003eAutomotive\u003c\/span\u003e\n        \u003cspan class=\"tag\"\u003eRefinishing\u003c\/span\u003e\n        \u003cspan class=\"tag\"\u003eSurface Prep\u003c\/span\u003e\n        \u003cspan class=\"tag\"\u003eFinish Sanding\u003c\/span\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-tool-nut-take\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eTool Nut's Take\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"eyebrow\"\u003eTool Nut's Take\u003c\/div\u003e\n      \u003ch3\u003eMirka 20-101-400 Base Cut 9 in. x 11 in.
