Pack Size

Idealseal Firecheck Intumescent is an acrylic based, halogen free joint sealant formulated to form a char coat when temperatures exceed 125°C resisting the passage of fire and smoke. 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 noncorrosive to metals. The sealant achieves a 4 hour fire rating tested to BS EN 1366-3: 2004, BS EN 1366-4: 2006 and BS476 Part 20. It can also be used as an acoustic sealant with a Sound Reduction Index of 55Db tested to BS EN ISO 140-3: 1995.

USES

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. It also has very good adhesion to most building materials including concrete, brickwork, aerated concrete, painted wood, anodised aluminium and PVCu. Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene and bituminous substrates. For joints where movement exceeds ± 7.5% of joint width or in external joints use Idealseal Firecheck Plus Silicone.

APPLICATION

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.
