Everbuild Power Pro Sealant Gun – 400ml

The Everbuild Power Pro sealant gun is what you reach for when you’re on a job that demands more than a cheap throwaway gun can give you. Designed for heavy duty use, it handles both 310ml and 400ml cartridges, which makes it one of the more practical options on the market for tradespeople who regularly switch between cartridge sizes. Whether you’re sealing around windows, pointing up bathroom suites or applying fire-rated or structural adhesives, a gun that fails mid-bead is nobody’s idea of a good time.

The extra pull trigger is where this gun earns its keep. High-viscosity products like power grab adhesives and thick sealants require real grip strength over a long shift, and a lightweight trigger mechanism will have your hand aching by mid-morning. The extra leverage here takes the strain off without sacrificing control over the bead.

What Makes the Everbuild Power Pro Stand Out

The swivel action barrel is a feature that sounds minor until you’ve spent twenty minutes applying sealant in an awkward corner. Being able to rotate the cartridge rather than your wrist is a small detail that adds up quickly across a full day’s work. It means you can keep consistent pressure and a cleaner line without contorting yourself into shapes your back will complain about later.

The hook end is a practical addition for keeping the gun close to hand on site without setting it down on a dusty surface or balancing it somewhere precarious. Anyone who’s knocked a loaded sealant gun off a scaffold board will appreciate that more than most.

Fits Both 310ml and 400ml Cartridges

The dual cartridge compatibility is genuinely useful. The 400ml format is increasingly common with construction adhesives and high-yield sealants, and a lot of older or cheaper guns simply won’t accept them. The Power Pro takes both without fuss, so there’s no need to keep a second gun in the bag for the larger cartridges.

At under a tenner, this is a solid, dependable tool that holds up to trade use and doesn’t ask much in return.
