Part of the 3M 211K series, it uses a J-weight cloth backing that provides flexibility for contour sanding while maintaining enough support for flat-surface finishing passes. Aluminum oxide abrasive is a reliable choice for general-purpose material removal on wood, metal, and composites. This sheet is rated for dry use only and is not waterproof or load-resistant, making it best suited for fine finishing rather than aggressive stock removal.\u003c\/p\u003e\u003cp\u003eThis sanding sheet fits residential and light commercial finishing applications. It is commonly used by finishing carpenters, painters, and general contractors for between-coat sanding on wood surfaces, light deburring of metal components, and surface prep before priming or topcoat application. The super fine 400-grit designation suits final-stage prep work where scratch patterns must be minimized before applying sealers or finish coats.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 grit aluminum oxide abrasive for super fine surface finishing\u003c\/li\u003e\n\u003cli\u003eJ-weight cloth backing provides flexibility for both flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eSeries 211K construction engineered for consistent cut and finish\u003c\/li\u003e\n\u003cli\u003eDry-use only configuration keeps the sheet appropriate for controlled finishing environments\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per sheet for easy handling during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for use with hand-sanding blocks and orbital finishing sanders that accept standard sanding sheet formats.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSanding sheets are installed by finishing trades, carpenters, and general laborers as a consumable abrasive. Secure the sheet firmly to the backing pad or sanding block before use to prevent slippage. Do not use this sheet wet or with liquid lubricants, as it is rated for dry use only. Inspect the sheet for loading or glazing during use and replace when cut rate degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Super Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 211K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry or Wet\/Dry\u003c\/strong\u003e: Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Resistant\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000118258\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51695175631154,"sku":"7000118258","price":18523.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e67f48fa32f6962b106316173b5a27c3.jpg?v=1788332105","url":"https:\/\/voomisupply.com\/products\/3m-7000118258-sanding-sheet-400-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
