This is a PSA abrasive strip designed for aggressive sanding and surface preparation. Model Number: \u003cstrong\u003e40-364-036\u003c\/strong\u003e. If you need to knock down material quickly before moving to finer grits, this is the kind of strip that makes sense.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is the coarse \u003cstrong\u003eP36 grit\u003c\/strong\u003e. That grit level is meant for serious removal, not finish sanding. It is the right choice when you are leveling rough surfaces, stripping heavy buildup, or starting the first pass on a surface that needs a lot of correction before refinement.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out a \u003cstrong\u003especially reinforced backing\u003c\/strong\u003e and its \u003cstrong\u003eProgressive Bond\u003c\/strong\u003e technology. In practical terms, that means the strip is built to handle higher sanding loads without giving up durability too early. The reinforced backing matters on edges and harder-working contact points where cheaper abrasive strips tend to wear out fast or break down unevenly.\u003c\/p\u003e\n      \u003cp\u003eAnother useful detail is flexibility on curved surfaces. A lot of aggressive abrasives cut well but fight you when the work is not flat. This Mirka strip is built to stay useful in shaped or contoured areas while still giving you the bite you expect from a coarse sanding product. Mirka also notes low clogging, which helps the abrasive keep cutting instead of loading up early.\u003c\/p\u003e\n      \u003cp\u003eThe \u003cstrong\u003e70 x 420 mm\u003c\/strong\u003e format makes this a purpose-built abrasive strip for tools and sanding setups that accept that size and use a \u003cstrong\u003ePSA\u003c\/strong\u003e attachment method. If your work depends on secure adhesive-backed strips rather than hook and loop, this setup is simple and dependable. It is a practical choice for users who want a firm hold during aggressive sanding passes.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a good fit for bodywork, wood surface prep, paint removal, filler shaping, and other heavy sanding tasks where speed matters more than finish quality on the first pass. Pros will appreciate the durability and cut rate. Serious DIY users will like it when they have rough prep work that would waste time with finer paper.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt to Remove Material Fast\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\/20260623786_1.jpg\" alt=\"Mirka Coarse Cut 70 x 420 mm PSA P36 abrasive strip for heavy sanding and surface preparation on wood, filler, or coated materials in shop work\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eIf your first sanding pass is about removing material, not babying the surface, this strip is in its lane.
