Acoustic and Intumescent Sealant is an absolute essential for soundproofing. General advice for the majority of soundproofing products, especially with the use of Acoustic Plasterboard, or installing rigid materials, is to leave a 2-5mm gap from the perimeter to reduce ‘Flanking Transmission’, a negative impact of sound taking an alternative route to the direct and ‘obvious’ path, for instance through the wall and not the two adjacent walls. This form of ‘Flanking Transmission’ is where sound passes between two solid materials in contact. Acoustic Sealant acts almost like a putty, meaning that it does not set solid. Acoustic Sealant is also to be used between Acoustic Plasterboard layers to increase the air-tightness of the ‘acoustic barrier’.

  • Cut off a suitable section from the plastic nozzle creating a pea-size exit hole to give you a suitably sized bead of sealant.
     
  • Pierce the metal lid through the nozzle with a screwdriver (or other long device) to expose the sealant. Forgetting to do this may cause the sealant to come out of the back of the cartridge when applying pressure with the gun.
     
  • Lock into the Jumbo Applicator Gun. 300ml will not be suitable here.
     
  • Apply force to the gun to expose sealant. If none appears to be coming out with force applied, try making sure the metal lid was pierced correctly.
     
  • Apply to installation instructions given on that particular Acoustic System.
