Product Description

Used in conjunction with either intumescent slabs or also non-fibrous slabs, the mortar provides a permanent fire stopping solution for load-bearing floors, walls and ceilings. For areas over 600 x 900mm, it’s essential to reinforce with 30mm chicken wire mesh, fixed with FB/C straps and support battens. Refer to the Technical Data Sheets for full details of the correct installation of mortar.

In the case where pipes, services or cables pass through the surface of a wall or floor, it is essential to fit Intumescent Wraps, Firoblok or Intumescent Collars to reinforce fire protection.

Available in dark grey, however also available in pink to identify mortar as fire-rated if required. Should you wish, we can supply a light aggregate to add to the Fire Mortar in 6.25kg bags.
