Fast-curing, two-part, self-expanding polyurethane foam for watertight seals

Sika Boom®-405 Water Stop is a two-part, fast curing, self-expanding polyurethane sealing foam that doesn't need ambient moisture to cure. Its high density and very fine, predominantly closed cell structure lead to a watertight seal in wall openings for pipes, ducts or pipe connections. The special packaging allows the application to be interrupted and then resumed by replacing the nozzle.

  • Tested for up to 1 bar water pressure.
  • Multiple instances of partial discharge possible.
  • Ready to apply (no pre-activation needed).
  • Very fast curing.
  • Good dimensional stability when cured (no shrinkage or post-expansion).
  • Good thermal insulation.
  • Can be cut, trimmed, sanded and painted.
