FSPG Hi-Graphite HPE Sealant

FSPG Hi-Graphite HPE Sealant is a water based, acrylic sealant utilising a reactive formula that has intumescent properties to reinstate the fire resistance performance of wall and floor constructions where the penetrations of single or multiple services are present.

FSPG Hi-Graphite HPE Sealant expands upon contact with heat, the high pressure reactive process ensures that the material will expand up to 20 times under an expansion pressure of 7 bar. FSPG Hi-Graphite HPE Sealant is supplied in 310ml cartridges, 600ml foils and 5kg, 10kg and 20kg pails. The sealant is gunned or trowelled into the annular space in or between the separating elements to a specific depth in order to maintain the fire resistance of the construction in the event of a fire.

Rigid wall and floors, flexible wall and batts in wall and floor.
Linear Joints up to 20mm wide.
Large service openings up to 300mm x 750mm.
Batt aperture up to 1100mm x 750mm.

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 Hi-Graphite HPE 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 characteristics of all available sealants for performance capabilities, hardness after weathering, movement capabilities in both extension and compression, adhesion properties and chemical resistance.
Combustible service penetrations must be independently supported each side of the seal.
Mineral wool (min. 80kg/m³) or PE backing rod where required can be used as backing material for FSPG Hi-Graphite HPE Sealant. Backing material is not needed within all installations, though the FSPG Hi-Graphite HPE Sealant should be installed correctly to achieve the performance needed. Leave a minimum depth of 25mm to install HPE.
Apply FSPG Hi-Graphite HPE Sealant to the remaining space around the penetrations. The sealant should be installed to the minimum 25mm depth within a minimum 20mm annulus around the service.
Once the FSPG Hi-Graphite HPE Sealant has been installed to the specified depth on both faces of the penetration seal, smooth over the seal. This can be done with a spatula and water.
