PFC Corofil Firestop Compound is a specially formulated gypsum based mortar, which is mixed with water to be trowelled or poured around service penetrations. Plastic pipework must be protected with either PFC Corofil Firestop Collars or Intumescent Pipe Wraps (see technical data sheets). In floors, depending on the hole size, PFC Corofil permanent shuttering panel (50mm) is cut and friction fitted between services and the edges of the floor slab. Firestop Compound is then trowelled over the shuttering to a depth of 25mm thick and 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 may be cast into blocks which are built into walls.

Install PFC Corofil Firestop Compound to provide up to 6 hours fire protection to all service penetrations through fire rated walls and floors. Installation to be fully in accordance with manufacturer’s instructions.
