Soudaseal FR

An elastic SMX hybrid-polymer sealant and adhesive for documented passive-fire joint systems, combining movement capability with tested assembly performance.

Product description

Elastic fire-resistant joints

Soudaseal FR combines hybrid-polymer movement capability with use in documented passive-fire joint systems, including selected internal and external window, door, expansion and connection joints.

Tested assembly performance

Published performance can reach four hours under EN 1366-4 or BS 476 Part 20 in matching tested configurations. Use the current application manual to match the joint geometry, backing, substrates and project requirements.

Preparation and application

Follow the product instructions step by step.

Use the guidance and documents for your chosen product. Contact us if the English TDS or SDS you need is not listed below.

  1. 01

    Confirm that the sealant, joint movement capability and evidence are suitable for the proposed joint and exposure.

  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.

For the best result

Match the product to the materials and application.

These practical points help you achieve a reliable result.

  • For sanitary, food-area, cleanroom or fire-resistant work, choose a product whose current documentation covers the intended use and system.
  • Match the product and preparation to the joint dimensions, movement, substrate porosity, coatings and environmental exposure.
  • For the best result, follow the current technical and safety information for the selected product.
  • For unfamiliar materials, coatings or site conditions, test adhesion and compatibility on the prepared surface first.
