The correct compound, installation depth and supporting construction must match the services and dimensions covered by the manufacturer documentation.

Installation
How Fire Stopping Compound Is Used
Compound systems are commonly specified where a robust fire stopping seal is required around larger or multiple service penetrations.
Mixed for Installation
Many compound systems are supplied as a dry material that is mixed with water before application in accordance with the manufacturer's instructions.
Forms a Solid Seal
Once installed and cured, the compound forms a solid seal around the services within the opening.
Multiple Services
Tested compound systems may accommodate cables, cable trays, pipes and combinations of services depending on the approved detail.
Specification
Choosing the Right Fire Stopping Compound
Check the complete penetration detail rather than choosing a compound by fire rating alone.
Wall or Floor
Check the supporting construction, its thickness and whether the tested detail applies to a wall or floor.
Service Type
Identify the cables, trays, pipes or mixed services passing through the penetration.
Opening Size
Check the aperture dimensions, seal depth and service arrangement covered by the system.
