QWIKstitch is an ultra-low viscosity material formulated to penetrate deep into cracks, mending them back together. Its fast cure time makes quick work of repair jobs; concrete repaired with EUCO QWIKstitch can be opened to heavy traffic in less than one hour. QWIKstitch can be mixed with aggregate to make a tough mortar perfect for quickly repairing pop-outs and spalls. • Can be applied at a range of thicknesses with the use of clean, oven-dried silica • Very fast cure time • Static mixers available with needle tips - for neatly injecting very narrow cracks • Low viscosity - deep penetration into cracks • Wide application temperature range: 0°F to 110°F • Low VOC and no solvent odor Applications: • Cracked concrete surfaces, interior and exterior • Spalled floor joints • Repair of pop-outs and delaminations on floors Coverage: • 21.2 oz cartridge: 38 in³ * Actual coverage depends on temperature, texture, and substrate porosity.
