Everbuild Everflex AC50 Acoustic Sealant and Adhesive White 380ml

DESCRIPTION

If you're working on a partition wall, drywall installation, or any interior project where sound reduction matters, the sealant you choose makes a genuine difference. Everbuild Everflex AC50 is purpose-built for exactly these applications - a high-performance acoustic sealant and adhesive that handles both sealing and bonding in a single, easy-to-apply product.

Its primary strength lies in reducing sound transmission through plasterboard partition systems. Applied around perimeter joints, sockets, switches, and service penetrations, it closes off the gaps that allow noise to travel between rooms, a detail that's easy to overlook during a build but hard to fix once everything is boarded up.

Beyond its acoustic properties, AC50 works equally well as a structural adhesive, bonding plasterboard, wood, metal, and other common building materials with a strong, durable hold. The permanently flexible formula accommodates natural joint movement and vibration without cracking or losing adhesion over time, which is essential in partition systems that are subject to ongoing structural movement.

The water-based, low-odour formula is a practical advantage for indoor work, no need to ventilate aggressively or down tools while the smell clears. Clean-up is straightforward too, which makes it a reliable choice for both professional contractors managing tight schedules and DIY users tackling home improvement projects. The smooth white finish is paintable once cured, so it integrates cleanly into finished surfaces without leaving a visible bead. A built-in mould-resistant biocide adds long-term hygiene protection, particularly useful in areas prone to moisture or condensation.

For adhesive applications, apply the adhesive to the surfaces and press firmly together. Follow drying and curing times as per the specific application.

WARNINGS

Keep out of reach of children. Wear protective gloves and avoid contact with skin and eyes. Use only in well-ventilated areas. May cause serious eye irritation.

A genuinely versatile product that earns its place on any interior build or renovation project where sound control and a quality finish both matter.
