Off-site application can move work earlier
Controlled shop conditions can support application before erection, but transport, lifting, connections and site repairs remain part of the final system.
On-site application follows the erected frame
Site spraying can include connections and repaired areas in one sequence, while requiring access, masking, environmental control and coordination with other trades.
The right route is project-specific
Programme, architecture, handling, environment, access and responsibility for repairs should be compared before procurement.
Project note
Final product selection, thickness and acceptance criteria must follow the approved tested system, responsible design and project specification. This article is contractor guidance, not a substitute for project fire engineering.
