Sikaflex Self-Leveling Sealant is a single-component, premium-grade polyurethane sealant engineered to seal horizontal expansion joints in concrete and cementitious slabs with minimal effort. This self-leveling formulation is ideal for driveways, sidewalks, balconies, warehouses, and other concrete applications where professional results are required without intensive finishing work.
The sealant’s accelerated curing capacity allows it to be applied to new concrete just 24 hours after pour, or to wet concrete as soon as one hour after rainfall. Once cured, it remains flexible and waterproof, providing durable protection for concrete joints and structures.
Features and Benefits
- Self-Leveling Action: The sealant naturally flows into joints and settles to a flat, professional surface without manual tooling, troweling, or knife work.
- Bulk 29-Oz. Size: The generous cartridge volume is designed for large projects, reducing the need for frequent cartridge changes.
- Fast Application to Wet Concrete: Can be applied to new concrete 24 hours after pour or to wet concrete just one hour after rainfall, enabling faster project timelines.
- Flexible and Waterproof: Remains flexible after cure and is waterproof and water-immersible, protecting joints from moisture.
- Indoor and Outdoor Versatility: Performs reliably in both covered and exposed applications, making it suitable for diverse construction and maintenance projects.
