Everbuild Everflex AC50 is a strong and flexible acoustic sealant and adhesive. It can be used for filling gaps in areas where sound might escape and is specially formulated for sealing and bonding plasterboard or insulation boards. It can be used for walls, ceilings and dry linings, and is for indoor use only.

It’s acoustic-rated to BS EN ISO 140/3 requirements (the measurement of sound insulation in buildings and of building elements) and is also non-flammable. As the name Everflex suggests, the sealant is permanently flexible throughout its working life, allowing for natural movement. The high-strength silicone is solvent-free, making it more pleasant to work with.

Unlike many sealants, the white Everflex AC50 can be painted over. British brand Everbuild has specialised in sealant, adhesive and building chemicals for almost 30 years, so you know you’re in safe hands.
