Mixed from equal parts A and B, it creates a strong, flexible bond on both concrete and wood subfloors above, on, or below grade, with high water resistance to surface flooding. Suitable for ColorFields rubber tile and sheet, rubber tile, and rubber or vinyl stair treads. Sold as a two-part 1 gallon package (Mat # 124114).\n  \u003c\/p\u003e\n\n  \u003cdiv class=\"pft-notice-critical\"\u003e\n    \u003cstrong\u003ePot life warning — 15 to 20 minutes:\u003c\/strong\u003e Once Parts A and B are mixed, working time is only 15–20 minutes at 72°F — significantly shorter than other two-part adhesives in this line. Mix only what you can spread and cover within that window. Pour the entire mixed contents onto the subfloor immediately after mixing to slow curing.

Key differences — MR-721 has a much shorter pot life (15–20 min vs 45–50 min) and cannot be used over cut-back adhesive residue. MR-725 handles cut-back residue and lower temperatures (down to 50°F). If your job site has cut-back residue or you need more working time, MR-725 is the better choice.\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pft-section\"\u003e\n    \u003ch2\u003eIdeal For\u003c\/h2\u003e\n    \u003cdiv class=\"pft-use-case-list\"\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eColorFields Rubber Tile \u0026amp; Sheet\u003c\/span\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eRubber Tile\u003c\/span\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eRubber \u0026amp; Vinyl Stair Treads\u003c\/span\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eHeavy Foot \u0026amp; Vehicle Traffic\u003c\/span\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eFlood-Prone Areas\u003c\/span\u003e\n      \u003cspan class=\"pft-use-case-pill\"\u003eBelow-Grade Concrete\u003c\/span\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cp class=\"pft-availability\"\u003e\n    \u003cstrong\u003eAvailable through PreFloorTools.com.\u003c\/strong\u003e Sold as a two-part 1 gallon kit. \u003cstrong\u003ePart B is a hazardous material — obtain and review both SDS documents before ordering.
