Product Description:

Firestem™ Mortar is a fire rated load bearing system providing up to 4 hours fire protection to compartment walls and floors around service penetrations.

When mixed with water it can be poured or trowelled into service penetration openings preventing the passage of flame, smoke and toxic gases for periods of up to 4 hours.

Installation

Horizontal Seals
(load bearing in concrete floors)

  • Form a temporary (or permanent) shutter to the underside of the floor
  • The correct amount of Firestem™ Mortar is then mixed by hand or power mixer and cast into the aperture
  • This is then tamped down to consolidate to a minimum thickness, also ensuring that there are no gaps left behind penetrations
  • note: Any plastic pipes penetrating the seal shoule be fitted either with Firestem™ Fire Collar or Intumescent Pipe Wrap
  • On instruction, the wraps would be applied aroung each plastic pipeprior to the casting of the compound so that they would be embedded within the seal
  • Fire Collars can be embedded or fixed externally when the compound has set
  • If a temproary shuttering has been used, this is then removed

Vertical Seals

  • The correct amount of Firestem™ Mortar is then mixed by hand or power mixer
  • The remaining face of shuttering will be installed in stages.  this will allow the compound to be poured or plastered into place and allow tamping/consolidation of the material
  • The curing time of the compound may vary between 25 minutes and 1 hour depending on the water content and ambient temperature
  • If temporary shuttering has been used this is removed when compound is dry
  • note: For plastic pipe penetrations, see horizontal seals
