K12 delivers industrial-grade strength that outperforms conventional concrete. With 40–45 MPa compressive strength and ≤ 300 mm³ abrasion resistance, it withstands heavy forklift traffic and constant foot traffic without cracking or dusting. Its versatile formula handles thicknesses from 3 mm to 30 mm in a single pour — from thin resurfacing to deep pothole repairs — one product covers every job.
K12 gets your floors back in service fast. Walkable in just 2–3 hours and ready for light traffic the same day — compared to traditional concrete repairs that take days to cure. Its self-leveling technology spreads smoothly and finds its own level, delivering a perfectly flat finish with minimal manual troweling. Less downtime, faster completion, and no repeat repairs mean real cost savings from day one.
Manufactured under ISO 9001 certified systems with premium German additives, K12 delivers consistent, reliable performance in every bag. It's fully compatible with all major floor finishes — epoxy, polyurethane, carpet, vinyl, rubber, natural stone, and more — providing a smooth, highly bondable base. Plus, its low-VOC, water-based formula is safe for indoor use and eco-friendly, reducing waste by repairing instead of replacing concrete.
