10 Best Cordless Caulk Guns 2025 in the United States

The DEWALT 20V MAX Cordless Caulking Gun is designed for both DIY enthusiasts and professionals who need a reliable tool for applying adhesive. One of its standout features is the variable speed trigger, which allows users to control the flow of caulk with precision. This is particularly useful when working on detailed projects where accuracy is crucial. Additionally, the speed dial lets you set both maximum and minimum flow rates, offering flexibility for different applications.

The anti-drip feature is another significant advantage, as it automatically retracts the plunging rod when the trigger is released, preventing messy drips and waste. This makes it easier to work neatly, especially in tight spots. The quick-connect interchangeable canister trays add convenience, allowing users to switch between different cartridge sizes without hassle, which can save valuable time.

The built-in LED light is a great addition for working in dimly lit areas, ensuring visibility as you apply your adhesive. The hang hook for easy storage is also practical, making it a user-friendly option for both home projects and professional work.

The Milwaukee 2641-20 M18 10 oz Caulk Gun excels in ease of use and durability, making it a solid choice for both DIY enthusiasts and professionals looking for a reliable tool for their projects. Weighing in at 4.9 pounds, it strikes a balance between portability and sturdiness, which is beneficial for extended use without causing excessive fatigue. The cordless design adds to its convenience, allowing for unrestricted movement while applying caulk.

One of the standout features is its user-friendly design that simplifies handling, which can be especially helpful for those who may not have extensive experience with caulk guns. However, it’s worth noting that the product is sold as a tool only, meaning you'll need to invest in compatible batteries and chargers separately. This could be a drawback for users who are just starting and don’t already own Milwaukee M18 batteries.

The cartridge size compatibility is limited to 10 oz, which might be a constraint for those who use larger cartridges frequently. Also, while it boasts high durability, the actual longevity and performance under heavy use would require real-world testing to fully assess. The Milwaukee 2641-20 is likely a great fit for users who need a lightweight, durable caulk gun for occasional to moderate use, though those requiring larger capacities or already possessing other brands' batteries may want to weigh their options carefully.

The RYOBI 18V ONE+ 10 Oz. Caulk and Adhesive Gun (PCL901B) is a handy tool for those looking to tackle various caulking and adhesive projects without the hassle of cords. One of its standout features is the 18V battery power, which means it's cordless and offers better mobility. However, note that the batteries are not included, so you will need to purchase them separately if you don't already have a compatible RYOBI battery.

The thrust force is strong enough for most household and DIY applications, making it easy to apply adhesives and sealants smoothly. Speed control is another plus, allowing you to adjust the flow rate according to your needs, which is particularly useful for precise applications. The gun weighs 3.85 pounds, which is fairly lightweight, ensuring it is easy to handle and reduces arm fatigue during extended use. It is compatible with standard 10 oz cartridges, which is quite versatile for various caulking tasks.

Ease of use is further supported by a clear operator's manual, though some users might find initial setup a bit tricky if they are not familiar with cordless tools. Durability is decent, thanks to its metal construction, but some users have noted that it might feel less sturdy compared to more heavy-duty models. This caulk and adhesive gun is a solid choice for DIY enthusiasts and homeowners looking for a reliable, portable option for their caulking needs, though professionals might seek something more robust.
