PERMANENT REPAIR FOR HAIRLINE, SHRINKAGE & SETTLEMENT CRACKS Professional-grade polyurethane crack filler that penetrates deep into tight cracks and chemically “welds” concrete slabs together. Prevents cracks from spreading and restores long-term slab strength.
ULTRA LOW-VISCOSITY FORMULA FLOWS DEEP INTO TIGHT CRACKS Reaches places thick patching compounds and epoxies cannot. Ideal for repairing fine cracks in interior or exterior concrete floors, garages, basements, patios, driveways, pool decks, and other slabs.
FAST-CURING, HIGH-STRENGTH CONCRETE CRACK REPAIR Cures in minutes for quicker return to service. Hardens stronger than the surrounding concrete and won’t shrink, peel, chip out, or loosen — even under foot traffic or vehicle load.
NO GRINDING, CHISELING OR SPECIAL EQUIPMENT NEEDED Easy DIY application using any standard 10-oz caulking gun. No routing or heavy prep work required. Perfect for concrete crack repair before applying epoxy, polyaspartic, or other floor coatings.
