Description
Firestop Compound is a specially formulated gypsum based mortar, which is mixed with water to be trowelled or poured around service penetrations.
In floors, PFC Corofil 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 cure. 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 openings.*
Firestop Compound sets in 30-45 minutes and is capable of accommodating foot traffic in approximately 72 hours.
*Plastic pipework must be protected with either PFC Corofil Fire Stop Collars or Intumescent Pipe Wraps. (See data sheets)
