Backing Material
Mineral wool (min. 80kg/m3) or PE backing rod where required can be use as backing materials, though the Pyrocoustic Sealant should be installed correctly to achieve the performance needed.
Pyrocoustic Sealant to be used installing FSi Stopseal Batts.
For good adhesion the surfaces of the building elements shall be free of any dust or grease and may need to be primed on good clean, virgin concrete & masonry, no priming required.
Ensure that the aperture and services in question are tested with Pyrocoustic Sealant and the site conditions are within the application specification. An annular space needs to be present around the service to apply sufficient installation depth.
All services and apertures need to be clean and clear of all dust and loose particles. The aperture temperature needs to at 5℃ or above at time of installation.
Upon installation make sure that you install the Pyrocoustic Sealant around all services needed.
Once compacted, smooth off the Pyrocoustic Sealant to produce a professional finish.
