When we talk about caulking guns, what comes to mind is applying huge amounts of pressure just to get the caulk out and (hopefully) not create a mess on your project. However, with cordless caulking guns, you don’t need to think about thrust ratios or wearing out your wrists during hours of work.
If you simply want a convenient way to perform caulking around the house or on a job site, a battery-operated caulking gun is for you. Check out my reviews below of the best cordless caulking guns for you to consider.
My top choice is the DeWalt DCE560D1 20V MAX Cordless Caulking Gun, which is equipped with a variable speed trigger, allowing you to adjust depending on the project at hand. This will prevent overflow and creating a mess so, in the long run, it will save you adhesive.
Moreover, it even has an anti-drip feature to prevent such accidents. This anti-drip feature retracts the plunging rod automatically so that the adhesive flow is completely controlled.
If you want to make a quick change between different canister sizes, it has a quick-connect design that allows better productivity and usability. The cordless caulking gun will take up to 10 ounces or 300 ml of any adhesive.
What I like about this cordless tool is that it has an LED light, which is useful when you’re working in difficult positions and low-light situations. As with most cordless tools, it has a hanging hook for convenient storage.
The tool has a max speed of 21 inches per minute and weighs just 4 pounds, so it’s not too heavy to carry around. The caulking gun comes ready to use with a 20V MAX lithium-ion battery and a charger. It is backed by a 3-year limited warranty.

Moreover, the all-metal gears on this caulking gun will deliver up to 950 pounds of dispensing force.

This portable caulking gun has a 1:1 mix ratio with 950-pound thrust and 167-psi pressure.

The Methodology: What I Considered When Picking the Cordless Caulking Guns Featured Above
Do you want to know how I came up with the list above? To choose the best cordless caulking guns, you should consider the following:
Tool Weight and Comfort
Usually, cordless caulking guns weigh somewhere between 3 and 4 pounds. Having a lightweight yet durable caulking gun is important because it will decrease your hand and wrist fatigue at the end of the day. No one likes working with achy hands and having a comfortable caulking gun will give you some relief from that.
Moreover, an ergonomic grip on the caulking gun will help you to keep a stable hand, reducing and even avoiding errors altogether when applying your adhesive or sealant.
The speed of a caulking gun is measured in inches per minute (IPM) wherein the norm is up to 21 IPM. It also helps that a cordless caulking gun has a variable speed feature to make it adaptable to any situation or project. In most cases, the variable speed will also affect the bead size of the caulking gun.
Usually, variable speed features are adjustable using an on-board dial. Typically, you’ll have five or six settings for the caulking gun. The Makita XGC01T1 18V Cordless Caulk Adhesive Gun Kit has up to 66 IPM so it’s more suitable for urgent or quick jobs.
Most battery-powered caulking guns will accept 10-ounce cartridges (300 ml). However, if you need a sausage barrel setup for bigger projects, you need a caulking gun that will take up to 20 ounces, or 600 ml. You should know first whether you’ll only need a 10-ounce caulking gun for casual use or if you’ll need to use a sausage barrel for heavy-duty tasks.
There are, however, some caulking guns that have a convertible design that allows you to use both typical sizes of caulk cartridges, such as the Albion E18T600 Cordless Multi-Component Cartridge Epoxy Adhesive Gun and the DeWalt DCE580B 20V MAX Cordless Caulking Gun. These models are recommended for when you’re working on a jobsite or if you have a business.
The dispensing force is measured in pounds and affects your productivity if you’re working with stubborn adhesives and sealants. You will get somewhere between 900 and 1,300 pounds of dispensing force for the average cordless caulking gun. If you know that your caulk is very high in viscosity, consider a higher dispensing force for that.
Usability should be a great consideration in any DIY tool – caulking guns with a simple variable speed trigger and easy setup will save you time and boost productivity. Even if you’ve never done caulking before, it should be hassle-free to load and aim versus a manual caulking gun.
The majority of cordless caulking guns on the market today have an anti-drip feature. One problem that occurs in manual caulking guns is the excessive mess. Battery-operated caulking guns, on the other hand, prevent this mess from happening due to the plunger’s automated design. This not only avoids the mess but also conserves adhesive to avoid wasting money and material.
As these caulking guns are battery-operated, I recommend getting a tool that’s powered by lithium-ion so it holds a charge longer and will have no “memory effect” that will slowly drain its charge when not in use. Not to mention, lithium-ion charges faster than traditional Ni-Cad batteries.
LED Work Light
An LED work light is useful for dim situations, whether you’re making repairs at home or doing work on the jobsite. Fortunately, many cordless caulking guns on the market have this work light as not to compromise accuracy when aiming your tool.
As a whole, the DeWalt DCE560D1 20V MAX Cordless Caulking Gun is my top choice due to its quick-change canister system, just-right weight, and LED work light. The second product on my list is the Milwaukee 2641-20 M18 Caulk Gun, which is sausage barrel-compatible. My budget pick is the Ryobi P310G 18V Pistol Grip Power Caulk and Adhesive Gun, which is lightweight and easy to hold for beginners and weekend warriors.
For those who want a convertible unit for different projects, especially heavy-duty needs, the Albion E18T600 Cordless Multi-Component Cartridge Epoxy Adhesive Gun, and the DeWalt DCE580B 20V MAX Cordless Caulking Gun are great picks for you.
If you want something with a strong dispensing force, the Makita XGC01T1 18V Cordless Caulk and Adhesive Gun Kit is a great choice (1,100 pounds), as well as the Dianamix 20V Cordless Caulking Gun (1,250 pounds). These will work best for heavy-duty jobs, especially if your adhesive or sealant is high in viscosity.
