Flex Paste is a super thick rubberized paste that you spread, shape, form and seal to virtually any surface. It starts as a thick paste and dries to a strong, flexible rubber coating that seals out air, water and moisture. This moldable sealant clings instantly to surfaces and fills large gaps, cracks and holes without shrinking or washing away, making it an excellent choice for both interior and exterior repairs.
Whether you’re tackling foundation cracks, sealing roof leaks, repairing bath and shower areas, or preventing rodents and pests from entering your home, Flex Paste works on wood, glass, tile, concrete, aluminum, metal, brick, stucco, masonry, fiberglass, ceramic, PVC, EPDM and many other materials. It can be applied on dry or wet surfaces—even underwater—and the finished surface can be painted any color, shaped to fit any form, and resists UV damage, chemicals and mildew.
Features and Benefits
- Multi-surface adhesion: Bonds reliably to wood, glass, tile, concrete, metal, brick, roofing materials, PVC and numerous other substrates for versatile repair and sealing applications.
- Moldable before hardening: The thick paste texture allows you to shape and position it into gaps and hard-to-reach areas before it sets, ensuring precise, custom-fit repairs.
- Works wet or dry: Can be applied on dry surfaces or in wet conditions, including underwater applications, without dissolving or losing adhesive strength.
- Never shrinks or cracks: Expands and contracts while maintaining its seal, preventing future gaps and water intrusion.
- Paintable and flexible: Dries to a flexible rubber coating that can be painted any color and remains pliable to accommodate surface movement.
- Stay Fresh container: Patented container design keeps the paste fresh and ready to use between applications.
