| 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
hours.
Description
Firecote Intumescent Sealant is a one part emulsion acrylic based
sealant. It gives a firm yet flexible seal to joints in virtually

of fire for up to four hours.
Application
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.

Sitework
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
fire rating.
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.
