Firestop Compound is used to provide a fire rated seal around service penetrations in fire rated walls and floors.

Firestop Compound is a specially formulated gypsum based mortar, which is mixed with water to be trowelled or poured around service penetrations. Plastic pipe work must be protected with either Firestop Collars or Intumescent Pipe Wraps.
In floors a permanent shutter panel (50mm) is cut and friction fitted between services and the edges of the floor slab. Firestop Compound is then trowelled over the shutter to a depth of 25mm thick. This is allowed to harden. The Firestop Compound is then mixed to a pouring grade and tops the seal up to the required depth.
In walls, Firestop Compound is mixed into a stiff consistency for trowelling into smaller openings. In larger openings, Firestop Compound can be cast into blocks which can be built into walls. Firestop Compound sets in 30-45 minutes and is capable of accommodating foot traffic in approximately 72 hours.
