Hodgson Sealants Intufire is a single-component, water-based sealant designed to be fire-resistant and possess acoustic properties. It is utilized to create a strong and flexible seal in joints within a diverse range of fire-rated structures, demanding fire resistance for up to 4 hours. Its unique intumescent characteristics prompt the sealant to expand and form a char when exposed to heat, effectively halting the dissemination of smoke and fire through the joint.

 

Key Features

  • Excellent adherence to a variety of common building surfaces such as timber, plasterboard, masonry, blockwork, plaster, and concrete
  • Formulated utilizing a special acrylic emulsion to ensure a strong seal while maintaining flexibility
  • Fire resistance of up to 4 hours
  • Effective in reducing sound transmission within joints
  • Appropriate for both horizontal and vertical joints without compromising fire safety rating
  • Joint flexibility with a movement capacity of ±12.5%
  • Can be painted over using solvent-based or water-based paints
  • Non-combustible and does not support combustion
  • Water-based, devoid of solvents and halogens, easily cleaned with water

APPLICATION

Joint Preparation: Before application, refer to the Technical Information Sheet named ‘Guidelines for Joint Design with Cartridge-Based Products.’

Surface Readiness: Ensure all surfaces are thoroughly clean, dry, and devoid of frost, grease, or loose substances. For a precise finish, use masking tape to shield the joint’s face edges; remove it promptly after tooling. Trim the cartridge’s screw thread tip and attach the nozzle. Adjust the nozzle’s diameter to match the joint size, then apply the sealant using a skeleton gun. Inject the sealant into the joints, guaranteeing no gaps or voids, and ensuring full contact between the sealant and both joint surfaces.

Finishing: Tool the sealant immediately after application, staying within the specified working time for the product. Some shrinkage may occur during drying. If a flush finish is desired, it’s advisable to slightly overfill/tool the joint to compensate.

LIMITATIONS

  • Inappropriate for use in joints that remain consistently damp or submerged.
  • Avoid usage on substrates that release oils or plasticizers.
  • Refrain from application in joints where the depth exceeds half the width unless accompanied by an appropriate backing material.
