It forms a permanently flexible, fire-rated acoustic barrier — tested to BS 476 Part 20 \/ EN1366-4:2006 with up to 5 hours fire resistance, and acoustic rated to BS EN ISO 140\/3. It is also tested for air permeability to EN13141-1.\u003c\/p\u003e\n\u003cp\u003eAC95 is used throughout acoustic floor, wall, and ceiling assemblies to seal flanking paths — gaps, perimeter joints, and penetrations that would otherwise bypass the acoustic treatment and significantly reduce overall performance. Each 900ml cartridge provides approximately 20 linear metres of coverage at a 6mm bead diameter. Requires a jumbo sealant gun for application.\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic floor assemblies\u003c\/strong\u003e — seal the perimeter gap between the floating floor and the wall, and any gaps between floorboards, before and after installation of the finish floor covering.

Highly porous substrates such as new plaster should be primed with Everbuild PVA Bond diluted 1:4 with water. Surfaces may be slightly damp but not wet — damp conditions will extend cure time. Do not apply below 5°C.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAs a sealant:\u003c\/em\u003e cut nozzle slightly larger than the gap to be sealed.
