Ampliar Description
Waterproof Sealing
Sika Boom®-405 Water Stop is a two-component, self-expanding, and very fast-curing polyurethane foam. Its high density and fine, predominantly closed-cell structure allow it to create water-resistant seals without relying on ambient moisture to cure.
Above- and Below-Ground Applications
It is suitable for sealing pipe and duct wall penetrations, cable conduits, pipe connections, precast concrete elements, and pipe plugs up to 200 mm in diameter. It can be used both indoors and outdoors and has been tested against water pressures of up to 1 bar.
Application and Limitations
The 320-ml container allows you to pause and resume application by changing the nozzle. The foam is touch-dry in about 3 minutes and can be cut after approximately 5 minutes. It must not be used in contact with drinking water, with continuously flowing water, as a structural fastener, or on components subject to vibration.
