Everbuild Sika Everflex AC50 Acoustic Sealant & Adhesive, 900ml
Everbuild AC50 Acoustic Sealant offers high flexibility, mould resistance, and excellent adhesion for plasterboard and insulation boards.
Everbuild Sika Everflex AC50 Acoustic Sealant & Adhesive is a high-performance, permanently flexible solution that provides excellent adhesion to most surfaces while being mould resistant and non-flammable. Once cured, it becomes overpaintable and is easy to clean up, making it a user-friendly choice for various applications.
This sealant forms both an acoustic and intumescent barrier, ensuring optimal performance when sealing gaps between plasterboard walls, floors, and ceilings. It is particularly effective for dry lining applications, providing enhanced soundproofing and fire resistance.
Key Applications as an Adhesive:
- Bonds plasterboard to plasterboard
- Adheres to wood, metal studding, and blockwork directly
- Seals and bonds most kraft-lined insulation boards
This 900ml cartridge is designed for professional and DIY use, delivering long-lasting durability and flexibility. Ideal for construction projects where both sealing and adhesive properties are required, the Everflex AC50 ensures a secure, high-performance finish.
