Everbuild B1 Fire Foam Gun Grade 750ml

Everbuild B1 Gun Grade Fire Foam - 750ml

Everbuild B1 Gun Grade Fire Foam is a quick-setting, fire-rated, one-part polyurethane foam that slows the passage of flames and smoke. It expands up to 50 times the can contents, giving up to 35 litres of pink, medium fine cell foam from a 750ml can, and provides insulation and sound deadening once cured.

The foam is tack-free in 7-9 minutes and can be cut, sawn or plastered after one hour, with a long-term temperature resistance of -40 to +80 deg C when cured. It is applied at +5 to +30 deg C to clean, sound stone, brick, concrete, plaster and timber, moistened with water first. Used for filling gaps around pipe entries and window and door frames where a fire rated foam seal is required.
