FlameSafe® FS 900+ Sealant is cost-effective, water-based and cures to form a flexible shield against the spread of fire and smoke. FS 900+ does not contain solvents and, as a result, is not toxic and will not damage plastic pipes or cable jackets. FS 900+ can be used in various penetrations and construction/architectural joint configurations. Examples of listed systems include metallic and non-metallic pipes, cable and HVAC penetrations, concrete floor-to-floor, floor-to-wall and wall-to-wall applications, as well as for concrete, CMU and gypsum head of wall applications requiring dynamic joint movement. FS 900+ is a versatile, yet economical solution for a wide range of through-penetration and joint construction conditions. All contact surfaces must be free of loose dirt, scale, oil or other foreign material. Installation of material may vary according to the size of the opening being protected and the type of penetrant. Installation temperature should be between 40°F to 90°F. Material may be installed using a standard caulk gun or troweled into place using a mason’s trowel or putty knife. FlameSafe FS 900+ dries quickly and in such a way that it can be painted and finished like the surrounding wall or floor.
