CERTIFIED FOR CONSTRUCTION USE – Everbuild Gun Grade expanding foam can be used as part of a fire-rated linear joint thanks to its high fire rating, signifying it can slow the passage of flames and smoke. QUICK CURING – This Everbuild pink foam expands and is tack-free in approximately 8 minutes, cuttable in 1 hour and fully cured in approximately 12 hours depending on temperature and relevant moisture. LARGE EXPANSION PROPERTIES – Grows up to 50 times the original can volume to economically fill large and unusually-sized gaps. VERSATILE APPLICATIONS – Ideal for filling irregular and large gaps where a fire rating is not required and where regular non-expanding fillers would fail, can also be used to help deaden noise and insulate behind cladding. FIRE RATED – Can be used to provide fire resistance in linear joint applications. ONE SIZE AND SHADE– This expanding foam 750ml pressurised cannister is coloured pink.
