Description

An acrylic, intumescent mastic for filling gaps, joints, voids and irregular holes to maintain the integrity of fire rated structures. In a fire the intumescent material in the sealant expands to many times its original volume to stop the passage of flames via the sealed gap. 

Typical applications for intumescent mastic include:

  • Sealing gaps around fire door frames,
  • 'Bedding down' fire hoods
  • Sealing around pipes and cables that penetrate firewalls.
  • General gap filling around fire rated structures

This mastic can be used on most common construction substrates, although, for unusual substrates, we recommend that a small area is tested before full application.

Long shelf life

Independently tested to provide up to 5 hours fire resistance depending on substrates, joint  depth/width and volumetric area (see table below).
