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).
Mastic is supplied in single 310ml cartridges or in discount packs of 12 cartridges (single colour packs).
In Brown, Grey or Off-White colour (all colours can be over-painted).
