The Bolthold CG40 hi thrust caulk gun is purpose-built for dispensing Bolthold EPX3 epoxy resin. Designed to handle the high resistance of two-component epoxy grout, this professional-grade caulk gun delivers the force required to properly mix and apply EPX3 epoxy without fatigue or material waste.
Unlike standard painter’s caulk guns, the CG40 features a 40:1 mechanical gain that provides the necessary pressure to evenly mix and dispense EPX3 epoxy. This makes installation faster, cleaner, and more consistent, especially in demanding asphalt anchoring applications.

...for the right job. This calk gun worked as well as it's made. It pumped out the two part epoxy like it was soft serve ice cream. No hesitation, buckling or hint of the need for extra force on my part. It's one of those tools when you use it, you wish you had THIS one instead of all the other junk you purchased hoping for quality only to be let down.. It was also my first time dealing with Fasteners Plus and I was pleasantly surprised at the efficiency and communication with each step. From ordering to shipping, they're a pleasure to work with.
Looks cool and worked great. Regular caulking gun might have been just fine though.
