Frequently Asked Questions (FAQs)
1. What advantages does a smooth rod caulk gun provide?
With an improved thrust ratio of 10:1 (or more), a smooth rod caulk gun requires much less pressure to push out a caulk bead. You can also control your bead much more efficiently since you can pull the trigger in small increments if needed.
2. What is the easiest caulking gun to use?
We found the easiest caulking gun to use during testing was the Newborn 250 Smooth Rod Revolving Frame Caulking Gun. It had plenty of power, a comfortable grip, a swivel frame, and dripped less than most other models on the list.
3. What is the metal rod for on a caulking gun?
Pierce the tube with the metal rod. This hook keeps the caulk in place. It also helps the trigger at the bottom of the gun function.
4. What is the difference between a rod and ratchet caulk gun?
Unlike ratchet drives that force the pressure bar to move in set small increments, the smooth-rod design of the dripless caulk gun provides you with an infinite range—a short handle squeeze for a small amount of caulk, a large squeeze to dispense more caulk.
