Everflex AC95 intumescent sealant and adhesive by Everbuild is formulated for fire-rated sealing. It seals and bonds plasterboards and insulation boards for walls, ceilings and dry lining applications. Adding a couple of beads between plasterboard sheets or around repairs before skimming stops cracking.\nThe intumescent sealant gives you up to five hours of fire resistance and meets EN 13666-4 standards, so it won''t compromise the building''s fire compartments. It''s also acoustic rated (to meet BS EN ISO 140/3) so is ideal for use in areas where sound might escape. With +/- 5% flexibility, the sealant allows for some movement, and as the name Everflex suggests, it doesn''t lose its elastic properties with age.\nThe white sealant is solvent-free, and is for interior applications only. Everflex AC95 sealant and adhesive is made by Everbuild, a British brand that has been manufacturing sealant, adhesive and building chemicals for almost 30 years.\n• Specifically formulated for fire-rated sealing and bonding\n• Designed for use on plasterboard and other kraft-lined insulation boards\n• Provides up to five hours of fire resistance\n• +/- 5% flexibility allows for movement\n• Solvent-free and suitable for interior use only\n• Fire rated - EN13666-4\n• Acoustic rated - BS EN ISO 140/3

DIY jobs Verified Purchase

Great product, did the job. I didn’t purchase the sealant gun as the job was in a confined space so I just opened the tube up and administered the contents from there, via a small pallet knife, which made the DIY job even cheaper

Cartridge size needs 3" diameter, 12" length gun

Product seems to be fine, and the builder liked the viscosity. Annoying though, that I had to buy a huge gun £19.99 to fit the 900ml cartridge. Even then, your problems not over because you need to have something long enough and thin enough to poke down the nozzle and pierce the seal.

Tube was damaged on the end causing end cap to come off where the nozzle was attached so had to chuck the hole tube in bin

Intumescent sealant needed to comply with building regulations, this one seemed to be a good choice

Good product, not so good packaging design

Easy to apply and sets well once I finally managed to get it out of the tube (had to cut it open as it doesn't fit a standard caulk gun)

Great value, but you do need a gun that will take 900ml cartridges. Sticks Fireline Plasterboard to steelwork really well with plenty of grab. Works well filling gaps and joins too. Don't forget to pierce the membrane first or you might distort the gun. (Not that I would do anything that stupid!)

Pretty good stuff. Impressed!!

wartwick Verified Purchase

Excellent product. Nice and sticky, goes in easily. Doesn't make a string bond, so better as a sealant than adhesive. Which was fine for my use anyway.

Price right - product right

I'm sure sealant works well but two tubes split from the top while using in the skeleton gun. Had to apply using a small tool trowel.
