Key item features

  • Versatile Application: A super thick rubberized paste designed for spreading, shaping, forming, and sealing a wide range of surfaces including wood, glass, tile, concrete, metal, and brick.
  • Durable Performance: Dries into a strong, flexible rubber that expands and contracts with surfaces, ensuring it will not shrink, crack, or peel once cured.
  • Watertight Seal: Effectively fills large gaps, cracks, and holes, creating a watertight, rubberized coating that seals out air, water, and moisture.
  • Extreme Adhesion: Capable of being applied on dry, wet, and even underwater surfaces, it will not dissolve or wash away and dries underwater.
  • Paintable Finish: Once fully cured, the rubberized coating can be painted any color, allowing for seamless integration with various projects.
  • Massive Coverage: This 12 lb container provides extensive coverage for both indoor and outdoor projects, ideal for massive leaks and flooding.
  • Easy Application: User-friendly for crafts, hobbies, gardening, and all types of projects, with best results achieved by applying a generous amount with firm pressure.
