For casual caulkers, a manual caulk gun is probably fine. But if you find yourself using one regularly or you have a big bathroom sealing, window insulating, or industrial adhesive applying project on the horizon, an electric model that’s faster and smooth to use (and won’t make your hand sore) is absolutely worth it. That’s particularly true when Walmart has a cordless caulk gun from a beloved tool brand on sale for nearly half off.
The Milwaukee M18 Cordless 10-Ounce Caulk and Adhesive Gun is on sale for $210 at Walmart, 45% off its normal $385 price tag. It’s a bare tool deal, so no battery or charger is included, but it is compatible with the same batteries that power your other Milwaukee M18 tools, starting at around $40.
Rare DealThis gun holds a standard 10-ounce tube of caulk at a time, and its all-metal gears help deliver industry-leading 950 pounds of dispensing force, enough to extrude the highest viscosity (read: most difficult to force through a tiny hole) materials. It has a variable-speed trigger for precise control of how fast the caulk or glue is coming out, constant flow technology that offers a steady flow rate, and an anti-drip mechanism that instantly stops dripping upon trigger release, ensuring your smooth, even caulk lines won’t be ruined by an ugly blob at the finish line.
One shopper wrote that this caulk gun “is a great tool” and “awesome.” It “caulks great, especially if you’re doing a big project” that necessitates a heavier-duty, grip-saving caulking solution.
Another customer liked that this caulk gun “arrived quickly” and “works fine.”

Milwaukee is a great tool company that’s been around for more than a century, so it’s no surprise that the Milwaukee M18 Cordless 10-Ounce Caulk and Adhesive Gun is a powerful, thoughtfully designed tool. For $210 at Walmart right now, it’s also a great deal, one you’ll be happy you snagged the next time you caulk for hours without making your hands sore for days afterward.
