The Everbuild brand is not only hugely popular with tradesmen and DIY'ers. It's quite literally huge - the biggest range in the business. In addition to core manufactured products the Everbuild range includes a wide range of ancillary items from sealant guns to dust sheets, line markers to masking tape.

The range of products Everbuild actually manufacture is extensive, from chemical blending for admixtures and water proofers through water based sealant manufacturing to the highly advanced polymer engineering undertaken in manufacturing silicone and hybrid sealants, as well as adhesives and a wide range of powder products.

Everbuild AC95 is a high strength, permanently flexible acoustic/intumescent sealant and adhesive specifically formulated for sealing and bonding plasterboard and other kraft lined insulation boards where a fire rated seal of up to 5-hours is required. It is a water based, solvent free formula which is easy-to-use and clean up and which adheres to just about all building substrates.

This Everbuild product is permanently flexible with high grab and will adhere to most surfaces whilst being mould resistant and Non flammable. When cured, it can be overpaintable and is easy to clean up. AC95 will form an acoustic and intumescent barrier by sealing gaps between plasterboard walls, floors and ceilings and dry lining applications.

As an adhesive Everbuild AC95 bonds plasterboard to plasterboard, wood and metal studding and direct to block work. It is also ideal for sealing and bonding most other kraft lined insulation boards.
