Developed by UN1ON Infinity to address structural vulnerabilities in masonry and concrete, UN1ON Krack Seal is a premium-grade, flexible, single-component crack-filling compound. Engineered specifically to tackle the challenging thermal expansions and moisture-driven wall damage common in the Mehsana region, this ready-to-use acrylic paste is designed to seal internal and external cracks permanently.
Unlike traditional rigid fillers or white cement that easily shrink, crack, and drop out over time, UN1ON Krack Seal cures into a tough, highly elastomeric, and waterproof seal. It locks out rain, groundwater rise, and ambient humidity, preventing moisture from seeping into internal walls and causing paint peeling, damp patches, or structural degradation.
Key Features & Technical Benefits
Shrinkage-Free Elastomeric Form: Formulated with advanced polymers that dry without shrinking, ensuring the filled cavity stays packed tightly while maintaining the elasticity needed to move with structural settling.
Superior Moisture & Water Resistance: Formulates an absolute waterproof barrier inside the crack, completely blocking water ingress, driving rain, and subsequent efflorescence (salt buildup).
Outstanding Substrate Adhesion: Exhibits excellent bonding strength over a wide range of building materials including cement plaster, concrete, brickwork, stone, and fiber cement boards.
Excellent Paintability & Sandability: Once fully cured, it forms a smooth, flexible surface that can be easily sanded and painted over with any water-based or oil-based exterior/interior emulsion without staining or ghosting through the topcoat.
