Best Caulking Guns (2026 Buying Guide)
A caulking gun is a device used to seal cracks and gaps. Caulk is made of either latex or silicone, both used for sealing a variety of materials like ceramic, glass, and wood. The caulk itself is contained in a tube, and the caulking gun holds that tube, regulates how much caulk is released, and controls where it goes.

Conclusion
Some of us need a caulking gun for regular use, while others need one only occasionally, and that difference should guide your choice. A pneumatic or cordless gun like the Chicago CP9885, DEWALT 20V MAX, or Milwaukee M12 makes sense for frequent, heavy-duty use, while a reliable manual gun like the Newborn 250 or 930-GTD is plenty for occasional home projects. Either way, look for a gun that's lightweight, dripless, and has the right thrust ratio for the materials you'll be using.
