QuelStop CE Marked HPE Graphite Sealant may be used for sealing around services such as cable, cable bundles, trays, ladders, combustible pipes, combustible insulations, either as part of a seal directly within the wall or floor substrate or as part of a QuelStop Fire Batt Seal.
All surfaces must be clean and free of any bond breaking contamination prior to application of the sealant.
The sealant should not be applied if the ambient temperature is below 5°C or above 35°C, as the adhesion may be impaired.
The QuelStop Intumescent HPE Graphite Sealant should be installed to the correct annulus and depth which depends on the penetrating services / material specification. The total annular space should be filled with compacted QuelStop HPE Sealant which is applied through the use of a standard sealant gun and once applied should be lightly compacted and smoothed off with a spatula to produce a professional and neat finish.
