VERSASPEED LS100: Rapid Hardening Horizontal Repair Mortar with Extended Working Time

VERSASPEED LS100 is a versatile, single-component repair mortar designed for horizontal, form, and pour repair projects. With its rapid strength gain and extended working time, it simplifies the repair process, requiring only the addition of water. This low-shrinkage, high early strength material enables fast turnaround projects, with repaired areas ready for standard tire traffic just 5 hours after the final set. Its appearance resembling concrete makes for seamless repairs on surfaces ranging from approximately 1/4” to 6” (6 mm to 15 cm) in thickness. Please note that VERSASPEED LS100 is a slower setting version of our popular VERSASPEED 100 material.
