Formulated for concrete floors, walls, precast, tilt-up, and masonry applications above or below grade, it delivers a light, workable consistency that holds a no-slump form once placed. With a full 1-inch single-lift depth neat — twice the depth of typical trowel-grade patch mortars — and a ready-to-seal window of as little as 24 hours, Ultra Patch is designed for contractors who need reliable, high-strength repairs with minimal downtime. It is equally suited to horizontal, vertical, and overhead applications.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTrowel-grade, polymer-modified concrete repair mortar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSet Time — Initial Set (ASTM C266, 70°F)\u003c\/td\u003e\n\u003ctd\u003e30 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSet Time — Final Set (ASTM C266, 70°F)\u003c\/td\u003e\n\u003ctd\u003e90 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressive Strength — 1 Day (ASTM C109)\u003c\/td\u003e\n\u003ctd\u003e1,500 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressive Strength — 7 Days (ASTM C109)\u003c\/td\u003e\n\u003ctd\u003e3,000 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressive Strength — 28 Days (ASTM C109)\u003c\/td\u003e\n\u003ctd\u003e4,000 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength Change — 28 Days, Air Cure (ASTM C157)\u003c\/td\u003e\n\u003ctd\u003e-0.08%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength Change — 28 Days, Water Cure (ASTM C157)\u003c\/td\u003e\n\u003ctd\u003e+0.03%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFreeze-Thaw Scaling Resistance (ASTM C672)\u003c\/td\u003e\n\u003ctd\u003e25 cycles = 0% loss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlant Shear Bond Strength — 7 Day (ASTM C882)\u003c\/td\u003e\n\u003ctd\u003e1,480 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexural Strength — 28 Days (ASTM C348)\u003c\/td\u003e\n\u003ctd\u003e465 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYield Per Bag\u003c\/td\u003e\n\u003ctd\u003e0.47 cu ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Single-Lift Depth (neat)\u003c\/td\u003e\n\u003ctd\u003e1 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMixing Water Per 50 lb Bag\u003c\/td\u003e\n\u003ctd\u003e5.5 quarts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReady to Seal\u003c\/td\u003e\n\u003ctd\u003eAs little as 24 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging\u003c\/td\u003e\n\u003ctd\u003e50 lb bag \u0026amp; 50 lb plastic pail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShelf Life\u003c\/td\u003e\n\u003ctd\u003e12 months (unopened, stored in dry facility)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical State (dry)\u003c\/td\u003e\n\u003ctd\u003eSolid \/ Powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eGray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Density (mixed)\u003c\/td\u003e\n\u003ctd\u003e2.6 – 3.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eUltra Patch stands apart from standard trowel-grade mortars by offering a full 1-inch single-lift depth neat — double the typical limit — combined with excellent hang for vertical and overhead work, eliminating the need for multiple thin lifts on deeper repairs.
