The Pro FP403 Fireseal Hybrid Sealant 290ml – Fire Rated Protection is a specialist sealing solution designed to help prevent the spread of fire, smoke, and toxic gases through joints and gaps in fire-rated walls, floors, and partitions. It is an essential product for maintaining fire safety in residential, commercial, and industrial buildings.
Formulated with advanced hybrid technology, FP403 provides excellent fire resistance while remaining flexible, allowing it to absorb building movement without cracking or losing its seal. This makes it ideal for sealing around door frames, service penetrations, wall joints, cable and pipe entries, and construction gaps that must remain fire-protected.
When exposed to fire, the sealant helps to maintain the integrity of fire-rated structures, slowing down the spread of flames and smoke and giving occupants more time to escape. At the same time, it also provides strong acoustic and air sealing, improving sound insulation and reducing draughts.
FP403 adheres to a wide range of materials including concrete, plasterboard, metal, wood, PVC, and masonry, making it suitable for both new builds and refurbishment projects. It is also paintable after curing, allowing for a clean, professional finish.
The 290ml cartridge works with standard sealant guns, making application easy and precise even in tight spaces.
This fireseal is ideal for builders, fire protection installers, electricians, plumbers, and building maintenance teams who must meet fire safety regulations when sealing joints and penetrations.
Unsealed gaps allow fire and smoke to spread quickly. FP403 provides a fire-rated seal that helps contain fire and protect building occupants.
Cheap sealants offer no fire protection. FP403 is fire-tested, flexible, and certified for fire-rated applications, ensuring compliance and safety.
