When to choose this product
For cracks, spalls and small defects in industrial and retail concrete floors. A two-component repair polymer that can be ground and polished with the surrounding concrete.
Product advantages
- This revolutionary polyurea/polyurethane hybrid is intended for use in repairing cracks and small surface defects such as bolt holes and pop-outs in industrial, retail or commercial concrete floors. This polishable repair system is for random crack and surface spalls/pop-outs and other surface defects in industrial concrete floors that are subject to wheeled traffic in industrial or retail concrete floors.
- Low viscosity allows penetration into cracks as narrow as 0.40 mm. At the TDS test conditions, traffic is possible in 15–30 minutes and grinding flush in about 25 minutes. Not a movement-joint filler.

Preparation and working conditions
Use on clean, dry concrete at 0°C or above; condition material to 21–27°C. Remove unsound concrete. Clean cracks up to about 3 mm with a wire wheel and vacuum. Wider or moving cracks need a different repair approach; the TDS directs wider routed joints to C² Joint Fill.
Practical advice
Test a representative area with the equipment and preparation planned for the job. Let it dry before assessing the result and coverage.
