Euco QWIKstitch – Rapid-Setting Urethane Crack & Spall Repair

Euco QWIKstitch is a fast-curing, two-component hybrid urethane repair liquid designed to quickly mend cracks, spalled joints, and uneven concrete surfaces. Formulated with ultra-low viscosity, it penetrates deeply into cracks, restoring structural integrity. Whether used in neat form or combined with aggregate, it cures rapidly—often allowing heavy traffic in as little as one hour—making it a reliable, efficient solution for both interior and exterior concrete repairs

Ultra-low viscosity for deep penetration and crack sealing
Rapid cure: tack-free in ~10 minutes, open to traffic in 30–60 minutes
Versatile: usable neat or mixed with oven-dried silica to create mortar for spalls and pop‑outs
Wide temperature range: performs between –18 °C and +43 °C (0 °F–110 °F)
Low VOC, solvent-free odor, suitable for indoor use
