FSPG Fire Resistant Sealant

FSPG Fire Resistant Sealant has been designed to be used in tunnel systems and is approved for use on the London Underground Network.

FSPG Fire Resistant Sealant is a water based, acrylic sealant used to reinstate the fire resistance of wall and floor constructions where apertures are penetrated by multiple services and linear gap joints where wall and floor constructions abut.

Fire resistance tested in flexible walls, rigid walls and floors.
Tested in Linear Joints up to 50mm wide.
Tested in large service openings up to 490mm x 150mm.
Tested with Metallic Pipes, Cables, Cable Bunches, Cable Trays and Cable Ladders.
Causes no known effects to plastic pipes, plastic cables, sheathing or metallic components.
For use in low movement joints, remains flexible.
Halogen free, resists fungi and vermin.
Shelf Life 18 months.

For good adhesion the surfaces of the building elements shall be free of any dust or grease and may need to be primed. On good, clean virgin concrete & masonry, no priming required, though refer to substrate compatibility requirements.
Ensure that the aperture and services in question are tested with FSPG Fire Resistant Sealant and the site conditions are within the application specification. An annular space needs to be present around the service to apply sufficient installation depth.
Consider the movement of the joint to be sealed. This should include thermal, wind pressures, settlement and differential movement of components.
Consider the characteristics of the substrates as they affect the choice of sealant, i.e. how the surface finish may be affected by sealant compounds and the possibility of discolouration due to oil migration or staining.
Consider the location and environment of the joint to be sealed. Exposure to temperature extremes, ultra violet light, radiation, chemical attack, standing water and vibration.
Consider the characteristics of all available sealants for performance capabilities, hardness after weathering, movement capabilities in both extension and compression, adhesion properties and chemical resistance.
Adequate space and accessibility should be provided for applying and tooling the sealant. Mineral wool (min. 80kg/m3) or PE backing rod where required can be used as backing materials, though the FSPG Fire Resistant Sealant should be installed correctly to achieve the performance needed.
