When it comes to large caulking or adhesive jobs, the DeWalt cordless caulking gun might be the tool for the job. This caulking gun uses DeWalt’s 20-volt battery lineup to squeeze caulking tubes with consistent, repeatable results. And since the user needs only to hold down the trigger, there’s less likelihood of fatigue.

Our shortlisted WorkPro model includes 9:1 and 18:1 thrust ratios from the same trigger, while the OX has an adjustable screw that lets you apply more or less pressure depending on what’s required. Note that this feature is not exclusive to pricier products – our most expensive contender (the Everbuild) doesn’t offer this functionality.This caulking gun doesn’t have a plunger. Instead, it pressurizes the space behind the caulk to push it through the tube, allowing for consistent pressure. It comes with a regulator to adjust the pressure for optimal flow as well.

Less-expensive guns tend to have a lower thrust ratio than their more expensive counterparts. A 6:1 ratio is fine for latex caulks, but adhesives, butyl and silicone caulks have a higher viscosity and require at least a 10:1 thrust ratio for proper application. Urethane and cement products require a 12:1 ratio. 3. What is the difference between a rod and ratchet caulk gun? 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. Our first impression of the Bates was that it felt rather cheap. It did, however, accomplish something no other caulking gun in the comparison did: It didn’t drip at all. When we considered that alongside its affordable price, the Bates really stood out. We also liked that it had a built-in cutter as well as a puncture tool under the frame to make getting started easier. Pneumatic: Air-powered caulking guns are among the most popular powered options for home workshops because there’s no battery to charge and they interchange with other air-power tools, but an air compressor is needed. In addition to the gun’s finger trigger, dispensing pressure can be regulated by adjusting the pressure on an air compressor.Battery powered: This bad boy has removable batteries and a charger, so users can run a bead of caulk in locations where electricity isn’t available, typically running 2 to 3 hours per charge. If there is a lot of caulking to do, consider investing in an extra battery so the juice won’t run out before the job is done.
