Ac50 Acoustic Sealant & Adh - 900ML

Everbuild Everflex AC50 Acoustic Sealant and Adhesive - 900ml

Everflex AC50 is a high-strength, permanently flexible acoustic sealant and adhesive supplied in a 900ml cartridge for use in a one litre mastic gun. It seals the perimeter gaps between plasterboard walls, floors and ceilings and bonds plasterboard directly to timber or metal studding and to blockwork.

The product is non-flammable, mould resistant and cleans up with a damp cloth within 30 minutes, and it can be overpainted once fully cured. As an adhesive it is gunned as a continuous 9 to 10mm bead at 250 to 350mm centres. Used for acoustic sealing of drylined partitions and for bonding kraft-lined insulation boards where a permanently flexible, high-grab joint is required.
