Idealseal Firecheck Intumescent is an acrylic based sealant that expands when heated above 120°C to restrict the passage of smoke and fire. It has very good adhesion to many surfaces and cures to form a tough, flexible, paintable seal. In addition, it is easy to apply, almost odourless and non-corrosive to metals. The sealant achieves a 4 hour fire rating tested to EN 1366-4.
Idealseal Firecheck Intumescent is ideal for interior joints where a fire retardant seal has been specified to prevent the passage of fire and smoke. It is commonly used in fire retardant constructions within the general construction, cold storage and marine industry. Applications include sealing joints in and around internal partitions, lap joints in fire-rated cladding and for sealing between fire doors and fire-rated walls. Not suitable in joints where movement exceeds ± 7.5% of joint width.
Surfaces must be clean, dry and dust free. Cut the cartridge seal and screw on nozzle which should be cut to required size. Gun the sealant firmly into joint ensuring no air is trapped behind. Tool with a spatula wetted whilst acrylic is still wet. If required place masking tape along joint edges, removing within 5 minutes of application.
