UN1ON KRACK SEAL is an advanced, ready-to-use, single-component acrylic crack-filling compound specially formulated to repair and seal surface gaps, plaster fissures, and structural cracks across residential, commercial, and industrial properties in Modasa. Designed with high-elasticity polymers, UN1ON KRACK SEAL penetrates deeply into plaster and masonry cracks up to 5 mm, forming a flexible, non-shrink, and weather-resistant seal that accommodates natural thermal expansion and building contraction without cracking or peeling. It effectively prevents water ingress, internal wall dampness, and efflorescence, protecting the structural integrity of internal and external walls, parapet joints, window frames, and plasterwork. Easy to apply with a putty knife or spatula, this fast-curing compound offers superior adhesion to cementitious substrates, plaster, brickwork, and concrete, while leaving a smooth, sandable finish that blends seamlessly under paint, primer, or exterior wall coatings for long-lasting protection.
