Per Lavina's published guidance, contractors typically start with 14, 30, or 70 grit metals to open the slab before progressing through finer grits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Lavina X \/ S series Quick Change mounting\u003c\/strong\u003e — the new X-Quick Change trapezoid pads attach directly to the heads of Lavina X and S series machines with \u003cstrong\u003eno special plates required\u003c\/strong\u003e. Important compatibility note: the new X-QC system is \u003cstrong\u003enot cross-compatible\u003c\/strong\u003e with the previous Quick Change tooling designed for older Lavina PRO and SPS models, which use a separate plate system. Verify your Lavina machine generation before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- 2-button (double-segment) configuration for heavier machines\u003c\/strong\u003e — two diamond buttons per pad create more surface contact than a single-button, extending tool life and stabilizing the cut. Lavina recommends double-segment tools for \u003cstrong\u003egrinders 30\" and larger\u003c\/strong\u003e, where the extra contact patch helps the machine pull weight efficiently. Single-button pads cut faster on lighter machines under 25\".\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Engineered for medium concrete (2,500–4,000 PSI)\u003c\/strong\u003e — per Lavina's official guidance, medium concrete is defined as 2,500–4,000 PSI, and the Grey bond is the recommended match. \u003cstrong\u003eLavina's color scheme is its own system distinct from other manufacturers:\u003c\/strong\u003e Yellow series for soft concrete, Grey for medium, Red\/Gold\/White for hard. Don't confuse with the Red = medium convention used by other tooling lines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Default 30-grit choice for typical commercial slabs\u003c\/strong\u003e — most commercial and residential concrete falls in the 2,500–4,000 PSI range that Grey is engineered for, making this the most-stocked pad on a Lavina-equipped truck. Run a Mohs scratch test if slab hardness is in question — if it tests above Mohs 7, step to a softer bond (Red, Gold, or White); if below Mohs 4, step to the harder Yellow series to avoid burning through pads.\u003c\/p\u003e","brand":"Niagara Machine, Inc","offers":[{"title":"Default Title","offer_id":52141658898713,"sku":"X2B-MC-0030","price":43.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/0d71896d-f6c4-4a6e-b712-48f49166ae26.png?v=1777491793","url":"https:\/\/shop.simiron.com\/es\/products\/lavina-grit-30-quick-change-grey-trapezoid-pad-with-two-button-for-medium-concrete","provider":"Simiron","version":"1.0","type":"link"}
