This is a high-strength, permane... morently flexible intumescent acrylic compound designed for sealing and bonding plasterboard and kraft-lined insulation boards in fire-rated and acoustic-controlled environments. It combines the performance of a sealant and adhesive, forming a dense, resilient barrier that expands under fire exposure to maintain compartment integrity. Water-based and solvent-free, it is simple to apply, non-flammable, and easily cleaned with water during use. It achieves up to five hours of fire resistance when tested to EN1366-4:2006, offering a 25% performance increase over standard fire-rated sealants. Once cured, it remains flexible and resistant to cracking, ensuring long-term acoustic and thermal stability in joint and panel systems. With a density of approximately 1.6 – 1.65 g/cm³ and a Shore A hardness of around 40, AC95 provides a stable, smooth seal with low slump characteristics, even on vertical joints. It performs reliably between –15 °C and +70 °C and maintains its integrity across a range of building materials including plasterboard, timber, metal, and blockwork. Designed for professional fire-stopping, acoustic isolation, and adhesive bonding applications, Everbuild AC95 offers high grab, mould resistance, and a consistent finish that supports both performance and aesthetic continuity in building interiors.
