A flexible intumescent sealant supplied in standard cartridge
form for the prevention of fire and gas penetration through small
service penetrations and internal joints and cracks for up to 4
Firecote Intumescent Sealant is a one part emulsion acrylic based
sealant. It gives a firm yet flexible seal to joints in virtually
any fire rated structure. Under a high temperature load it will
char and swell up to three time its orginal size resisting the passage
of fire for up to four hours.
Firecote Intumescent Sealant is appropriate for sealing joints,
voids and irregular holes in fire walls, partitions and other structures,
and for maintaining their integrity when sealing around pipes and
cables that penetrate them. It can also be used for internal perimeter
pointing of fire rated door and window frames.
Tested following the principles of BS 476 Parts 20 and 22 (1987)
Loss Prevention Council report No TE82044 and SGS Yarsley Report

The sealant must not be applied below an ambient temperature of
5 degrees C.
Ensure all surfaces are clean and dust free. Priming is not normally
required but unusual substrata shoud be tested. Insert polyethylene
foam backing into the joint to a depth of 1Omm below surface. Gun
apply the Firecote Sealant to a smooth, flush finish.
Joint width must be at least 6mm and can be up to 25mm. A 10mm
deep single seal will give a fire rating of 2 hours. A dual seal
i.e. a single seal on each side of a wall or floor will give 4 hours
Single seals should be on the fire rated side of the structure.
Where a neat finish is required use masking tape which should be
removed immediately the sealant is smoothed off.
