The Best Caulking Guns Tested in 2023

With its revolving frame, the Newborn 250 makes it easier to caulk around corners. No need to start and stop—simply rotate the barrel, and the angled tip of the tube rotates to the correct position to continue running a bead.

The Newborn 250 is built to last with a zinc alloy handle to reduce corrosion, and it features a hefty 18:1 thrust ratio to easily dispense medium-viscosity caulk, including butyl and acrylic. The tool also comes with a thumb release for dripless operation.

During testing, we found the Newborn 250 to be the easiest and smoothest for applying caulk and sealant. The frame rotated smoothly (certainly the smoothest of all the other models), and the hand grips were very comfortable. We also liked the built-in cutter that most high-thrust caulking guns don’t have. It did drip a bit, but the release was easy to access and press with one hand. The only complaint we might have is that just one handle has a rubber coating—coating both handles would be a benefit.
