Sikadur-20 Crackseal — Low-Viscosity Epoxy Crack Sealer for Concrete Floor and Pavement Crack Repair (140 ml)

Fine cracks on concrete floors and pavements present a specific repair challenge that standard crack fillers are not designed to address effectively. Paste-consistency fillers cannot penetrate fine floor cracks by trowel application — they bridge the crack surface without filling its depth, leaving a hollow repair that breaks down under wheel loads and foot traffic within weeks. What fine floor cracks need is a low-viscosity liquid system that flows into the crack under gravity, penetrates its full depth, and cures in place to seal the crack completely from the bottom up rather than just across the top.

Sikadur-20 Crackseal from Sika India Pvt. Ltd. is a low-viscosity epoxy crack sealer engineered for fine crack repair on concrete floors and pavements. The low viscosity of the mixed epoxy system allows it to flow freely into fine floor cracks under gravity — self-levelling across the crack width and penetrating the full crack depth before curing to a hard, durable epoxy seal that restores the structural continuity of the floor surface and prevents moisture and contaminant ingress through the crack.

The cured epoxy seal achieves high tensile and compressive strength at the crack interface, strong adhesion to the concrete faces of the crack, and chemical resistance to oils, fuels and cleaning agents commonly encountered on industrial and commercial floors. It is suitable for dormant cracks on warehouse floors, factory floors, car park decks, external pavements and any concrete floor surface where fine cracks need to be sealed permanently before the crack propagates further or allows moisture ingress that causes subsurface deterioration.

For floor repair contractors, facility managers and civil engineers handling crack sealing on concrete floors and pavements — Sikadur-20 Crackseal delivers the low-viscosity epoxy crack sealing performance that deep, permanent fine crack repair on horizontal concrete surfaces demands.

A construction chemical crack sealing solution from Sika for concrete floor crack repair — Sikadur-20 Crackseal is the low-viscosity epoxy specification for fine floor cracks where gravity fill and full depth penetration are the requirements.
