Description

EVERBUILD® B2 GunGrade Fire Foam is a quick setting one part polyurethane foam with fire resistance properties. The foam expands on application 1.5 – 2 times its original volume. Once cured, the foam can be cut, sawn or plastered over after only one hour providing the working temperatures (can and surfaces) are between +5oC to +25oC, ideally 20oC.
