Description
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).
