Fire Silicone B1 FR

A neutral, elastic silicone sealant for tested fire-resistant joint and penetration systems. The rating depends on the construction, joint size and backing material in the test report.

Product description

Where it fits

Use Fire Silicone B1 FR only in fire-resistant joints or penetration details covered by its test evidence.

System performance

Some tested joint systems are rated for up to four hours. Follow the relevant report for the joint width and depth, backing material, wall or floor and orientation. The product is supplied as a non-paintable finish; porous natural stone needs a compatible alternative.

Preparation and applicationFollow the product instructions step by step.

  1. 01

    Before starting, check that the sealant suits the joint movement and exposure and that you have any supporting report the project requires.

  2. 02

    Remove dust, grease, laitance, old sealant and loose coatings. Use the recommended primer or surface treatment where required.

  3. 03

    Use a suitable backing material where required, apply a continuous bead without trapping air and tool the joint before skin formation.

  4. 04

    Protect the joint from movement, water and contamination until it has cured sufficiently for service.
