Joint & Seam Filler

Fiber reinforced fill coat and seam treatment

Joint & Seam Filler is a gungrade, crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, Silyl-Terminated-Poly-Ether (STPE) is easy to gun, spread and tool.

Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge larger gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components.

  • Streamlines preparation by eliminating the need for joint reinforcing tapes.
  • Solvent free. Isocyanate free. Phthalate free. Complies with all VOC regulations.
  • Bonds and cures in wet weather and on damp substrates. Tolerates rain immediately after application.
  • Silane functional polymer provides superior long term adhesion, crack filling and weathering characteristics.
