BOSS FireMastic-300 Sealant

  • Description
  • Product Data Sheet
  • Work Photo Examples

Flexible fire and acoustic rated acrylic sealant. Suitable for sealing joints, linear gaps and service penetrations. Approved to AS1530.4-2014 & AS4072.1

This sealant is a one-part acrylic emulsion that is designed to resist the passage of fire, smoke and sound. FireMastic-300™ will intumesce and form a char when exposed to the heat of a fire, which will prevent the passage of fire and smoke for up to 5 hours in both integrity and insulation.

In normal use it will also maintain the sound reduction index of a structure.  FireMastic-300’s superior acoustic properties means it offers up to a 67dB sound reduction, making it ideal for high performance acoustic installation.

Sizes: 310ml / 600ml

Colours: Light Grey / White
