Bostik Pro FP403 Fireseal Hybrid Sealant 290ml

The Bostik Pro FP403 Fireseal Hybrid Sealant 290ml is a high-performance, fire-resistant sealant designed for sealing joints in construction where fire resistance, flexibility, and durability are essential. Formulated using advanced hybrid polymer technology, it provides a permanent, elastic, and watertight seal while preventing the passage of flames, smoke, and toxic gases in the event of a fire.

This sealant is suitable for both internal and external applications, offering excellent adhesion to most construction materials without the need for a primer.

Features

  • Up to 4 hours of fire resistance (tested according to EN 1366-4)
  • Hybrid polymer formula – strong, flexible, and durable
  • Excellent adhesion to concrete, brick, plaster, wood, and metal
  • Low shrinkage and paintable after curing
  • Weatherproof and UV-resistant – suitable for indoor and outdoor use
  • Solvent-free and low-odour formulation

Uses

  • Sealing fire-rated joints and gaps in walls, floors, and ceilings
  • Perimeter sealing around fire doors and windows
  • Service penetrations and expansion joints
  • Ideal for fire compartmentation and acoustic sealing
