  • An acoustic and fire resistant mastic

  • Specifically formulated to maintain acoustic integrity

  • Fire retarding mastics

An acoustic and fire resistant mastic that fill gaps that reduce soundproofing performance by up to 10%.

Acoustic mastic is unlike normal mastic in that it has been specifically formulated for the function of filling gaps while maintaining acoustic integrity. In addition all our acoustic mastics are intumescent in that they are fire retarding mastics.


The product should be applied as a sealant around all soundproofing Jobs. It should be borne in mind that just a 1% gap within a soundproofing job can reduce the performance by 10%. We recommend to actively leave a gap when sound proofing and then fill that gap with acoustic mastic. In this way you are sure you have created a seal.

Sealing floor boards which are not in view can also be a very effective way of increasing the sound proofing performance of a floor.
