Order Reference

Use Nullifire FS702 Intumastic Fire Resistant Acrylic Sealant to seal around dry internal joints, pipes and services to insulate and prevent the spread of fire and smoke for up to 240 minutes. Helping contain fires gives more time for evacuation of properties, saving lives, and may prevent more costly fire and smoke damage to a business, resulting in less downtime and faster re-opening.

Tack free between 15 minutes and an hour, the sealant can be over-painted with acrylic paints once fully cured and tools off easily with water. It may also be used in movement joints, offering a movement capability of up to 30%.
