Our take on the Bosch 10 Ounce Cordless Battery Powered Rod Caulk Gun GCG18V-20N

The Bosch GCG18V-20N is an 18V cordless rod caulk gun that holds standard 10 oz cartridges. It runs on Bosch's 18V Li-Ion batteries and is sold as a bare tool, so batteries and charger are separate. A rotating barrel, variable speed trigger and ladder hook make it easier to work overhead and at awkward angles than a manual skeleton gun. It suits contractors and serious DIYers already on the Bosch 18V platform who lay a lot of sealant or adhesive; occasional users may find a manual gun simpler and lighter.

  • 5-year limited warranty

Questions and answers

Does it come with a battery and charger?
No. It is a bare tool, so you need a Bosch 18V Li-Ion battery and charger, sold separately.
What size cartridges does it take?
Standard 10 oz cartridges. The barrel is a rod type, not a sausage or bulk frame.
Is it good for thick adhesives?
It has a medium thrust ratio, which handles sealants and most adhesives well. Very stiff, high-viscosity materials may push it to its limit.
Can I use it upside down or overhead?
Yes. The rotating barrel and ladder hook are made for overhead and ladder work, and the variable speed trigger helps control the bead.
How does it compare with a manual caulk gun?
It costs more and weighs more, but it saves hand strain on long or repeated beads and gives steadier speed control.
Which Bosch batteries fit?
Any Bosch 18V Li-Ion battery in the platform fits, including compact and Core packs.
Where is the Bosch 10 Ounce Cordless Battery Powered Rod Caulk Gun GCG18V-20N cheapest?
At Lowe's, for $299.00, as of our latest check.
