FyreFLEX® sealant (also known as firemastic or fire caulking) is water-based, acrylic sealant with intumescent properties designed to restrict the spread of smoke, heat and fire between rated walls, ceilings, and compartments.
With a fire rating of 4 hours per AS1530.4:2014 and an RW54 acoustic performance, this product comes in 300ml (tube), 600ml (sausage), and 10L (bucket) sizes.
Easily applied with a standard caulking gun, it is especially suitable for thin, hard to reach areas. FyreFLEX® works great for data communication cabling, power cables trays, steel copper piping, wall floor joints, and can be painted over if white (for finished walls plasterboard) or left as is if grey (for concrete applications).
