The Best Electric Caulk Gun

By Walter J. Farrell | LIVING

With about a hundred hours used for research and hands-on testing, the Milwaukee 2441-21 M12 10 oz Caulk Gun Kit owned the top spot in this review. Even with the 12 volts battery power and a carry 12 oz in its barrel, this electric caulk gun stood from the rest for its speed, precision, and comfort. Its trigger mechanism is backed with a six-speed option pushing materials at 21 IPM. Users are kept safe with the auto-retract plunger preventing spills and drips.

Finding cracks at home can be alarming if you are not familiar with the science of building things.

You research what to do and found a sealant. Now, you did some do-it-yourself repairs only ending up with strained hands.

You found a gun-like tool that promises you easy and fast application.

The problem with this is that this is not a basic repair tool that you know or is familiar to you. It looks heavy and complicated.

True!

To those who are not professional workers, an electric caulk gun is a complex tool that looks a bit scary.

Today, we will not only get to know what is this electric caulk gun. We will also look into its uses and advantage and provide simplified guidelines on how to choose the tool that fits you.

We came up with the top five electric caulk guns that has undergone levels of research and full-day testing for each of the guns.

The testing and review are backed with pertinent data from experts and other users and put into test by different persons having varied backgrounds in relation to the product.


How Do Electric Caulk Gun Works?

The electric caulk gun is used to hold the canister or cartridge to easily and conveniently squeeze out a tube of caulk sealant or adhesive with more precision. Instead of pressing the tube with your bare hands, you can use the caulk gun which has more power, more speed and is more consistent.

Since this is an electronic tool, you need to connect it to an outlet or charge the batteries for it to work.

It works by first pulling out the plunger from the gun to fit in the tube. Next, insert the tube of the sealant or the adhesive into the barrel of the gun. Before starting the gun, make sure that you set the speed of the plunger according to how you want to use it.

Cut open the tip of the tube, point it to the cracks and start with the trigger to lay down the sealant.


​Buyer’s Guide

Advantages

For those who want comfort, speed, and accuracy when dealing with sealing repairs for your own home or for professional works and projects, the electric caulk gun can be a useful tool.

Squeezing out the adhesive from its container can cause pain and discomfort with your hands. With the caulk gun, it has a mechanism that pushes out the sealant with only the pull of the trigger.

Its output is also more accurate or precise because of the speed and power and consistent throughout.

Things To Consider Before Buying an Electric Caulk Gun

1. Batteries

Most of the guns we’ve had in our review are cordless, which means it is battery powered.

Among the characteristics of the battery that you need to consider is its discharge and charging time. You can check the capacity of the battery by the amount of sealant it can produce in a single charge.

To determine whether the time or capacity is enough depends on your usage. For home use, electric caulk gun that can finish 10 oz in a single charge is fine. But, for heavier work, it might need more than the 10 oz capacity.

2. Trigger, dials and buttons

Each electric caulk gun has a distinct trigger, dials, and button forms. A vital factor with these part of an electric caulk gun is its ease of use. That is, it should be easily adjustable, within the line of vision while on use and it can be understood immediately.

There are speed dials that are just symbols, while others are in numbers making it easier to understand. Also, the softness of these items should be considered to avoid hand strain from pulling too hard. 

3. Speed

Not all jobs require the same speed and not all users are comfortable with the single speed. Hence, you might consider getting an electric caulk gun with different speed options. It can help in doing quality work as it lets you have more control of the gun.

4. Safety

The overall function and the specific parts of the gun should be safety for both the users and the work. Among the parts that should be considered are the anti-drip feature, light indicators, reverses, and rotations. All these should be efficient in securing that user is safe by giving control and that the work would not be messed-up.


​How We Assessed & Evaluated These Electric Caulk Gun

There are two sections of our evaluation process: research and data gathering and the hands-on testing.

The first section includes online and offline research about the product, its background, and what experts and users say about it. Our researchers also looked into the promised features of each product.

To supplement the data we have gathered, we asked professionals, the local vendors and families, and friends who own an electric caulk gun. We interviewed them regarding the product and to give their recommendations.

The researchers then created a criteria list to help us when we rank the electric caulk guns that would be part of our top five.

There were not very many options, and there were also limited brand selections. However, it was difficult to choose which should be chosen since there is no hands-on testing yet and the features seem to be similar. We based our ranking on our criteria, which was formed from the date we have gathered.

After thorough deliberation, our researchers have selected the top five electric caulk gun. For five days, a team of five testers subjected the guns in hands-on testing all of them trying on the gun in different settings.

They tried in doing sealing of cracks in the roof, bathroom and other rooms in at home and in offices. This is to test the efficiency and convenience of using the gun in different places (indoors and outdoors; with many and limited people). 


​5 Electric Caulk Gun Product Reviews

The first in the list comes from a brand that that been around since the 1920s. Part of their growing tools includes the Milwaukee 2441-21 M12 10 oz Caulk Gun Kit.

It looks less intimidating compared to the other products on review maybe because it only has a 10 oz barrel. It is also among the lightweight products with about 4 lbs weight. From its weight and length alone, our testers deemed that this can be suitable for home use.

As to the batteries, the description said that it could dispense up to 10 oz before you need to charge it again. During the testing, the testers did not have to charge even after they’ve finished the 10 oz sealant. It may be because there are five of them who used it at different speeds. Hence, the depending on your speed this caulk gun might still have more than its estimated oz capacity.

What our testers also like about the Milwaukee 2441-21 M12 10 oz Caulk Gun Kit is its speed variable of up to six-speed options. Each option is quite precise to their levels, where No. 1 is really slow, and six is pretty fast.

Our testers are a diverse group of people that have different skill levels in using the gun. They agree that the speed selections allows them to align it with their capacities.

They also tested the anti-drip feature by hanging the tool while on standby. According to the product description, the pressure is halted to prevent drips. The testers were amazed that it worked.

The issue with the tool, however, is with the assembly of the product. The testers who tried assembling it was a first timer in using the caulk gun to check how the gun fairs with first-timer users.

She said that it was quite difficult and will require strength. With the assistance of other testers, she was able to assemble the gun. So, the testers are one in saying that the product is difficult to put together. 

What We Liked

  • Lightweight
  • Variable speed
  • Anti-drip feature

What We Didn't Like

  • Quite difficult to set-up

The DEWALT DCE570B 20V MAX 29oz Adhesive Gun is closely the same with the DEWALT DCE560B 20V MAX 10oz/300ml Adhesive Gun. What sets this gun from one under the same brand is the oz capacity of 29 oz, which almost triple that of the other.

The testers said that it is really big that is appropriate for the industrial type of projects. They said that home DIY enthusiast might shy from this tool and opt for the smaller ones. One issue, however, that testers observed during the testing is that the barrel looks and feels weak and thin.

Despite its large barrel, it weighs the same with some of the electric caulk guns having 10 oz capacities with and without the batteries. Thus, some of the testers think that although it has a big barrel, it can be painless to use.

This DEWALT DCE570B 20V MAX 29oz Adhesive Gun also has a 20 volts battery power for its 21 IPM and a variable speed dial. These features all-in-all can give users different work modes that can suit any work settings. Hence, the big barrel size can be considered a bonus because the features and controls still allow the users to have control over the gun.

Since it has 20 voltage power, it can consume the entire 29 oz and will still have more power to do more. Therefore, work will not be halted as it is also simple when you want to replace the sealant or adhesive canister.

Like the DEWALT DCE560B 20V MAX 10oz/300ml Adhesive Gun its anti-drip feature appears to be impressive. 

What We Liked

  • 29 oz barrel
  • Lightweight
  • Variable speed
  • Anti-drip feature

What We Didn't Like

  • exclamation-triangle
    Barrel seems weak

More than a hundred years in the tools industry, Mikata has produced another tool to make industrial work easier.

The Makita XGC01ZB 18V LXT Lithium-Ion Cordless Barrel Style Caulk and Adhesive Gun are the most unique from the five electric caulk guns in the review. Instead of an open barrel, it has a sausage like a barrel where you fill-in the sealant or adhesive.

It was challenging to load the sealant or the adhesive because you need to siphon it into the gun due to its sausage barrel. So, when refilling this method can be messy compared to just changing the canister. This can also be time-consuming.

However, the testers all assent that though it is hard to fill-in the barrel, it can contain 20 oz of material. Some of the testers believe that with the volume capacity, they don’t always have to deal with refilling. Meanwhile, others think that it can easily be consumed when the work is massive or when it is always used.

With its 18 volts power, the testers find it impressive that it can dispense sealant and adhesive from 0 to 66 IPM. The range is very wide and varied, which the users can choose the speed based on their needs and skills.

The testers who are professionals and experts think that the maximum speed makes their work fast and easy, especially if they are doing big projects.

It expected that an electric caulk gun is heavy. But, the Mikata XGC01ZB 18V LXT Lithium-Ion Cordless Barrel Style Caulk and Adhesive Gun is comparatively heavier a five pounds without the battery and can reach to six pounds with batteries on.

However, these batteries are fairly powerful with the Star trademark that is computer protected and among the fastest charging batteries.

This includes a special LED light as overload indicator and another to add visibility while working.
andi Rake is shaped like a comb. This made it stood out from the rest.

The rake, or should we say comb, has a great size. It is 12 x 2 x 3.5 inches. It can be carried anywhere and be used for other rugs or covers like that of your car. So the usage is not only limited to your carpets.

In relation to that, it is also handy, just as its name suggests. It also means that this product is only good for smaller spaces. You will take some time if you use this for a large room.

It is a good product that scrubs off spots and pet stains while also revitalizing the carpet. You can count that it can make your old carpets look like brand new.
Now for its downside, we find the bristles too flimsy to untangle the fibers. You also can’t use too much force with this.

And since it is comb-like, you will have to bend down when cleaning. This could be tiring for your back. It too cannot pick up the hairs.

What We Liked

  • Up to 66 IPM plunger speed
  • Battery seems safe and powerful
  • Includes LED lights and LED light indicators

What We Didn't Like

  • Heavy

From the five products in the review, this electric caulk gun is similar to the Milwaukee 2441-21 M12 10 oz Caulk Gun Kit and the Ryobi P310G 18v Pistol Grip Variable Discharge Rate Power Caulk and Adhesive Gun with regard to the oz capacity.

The most apparent difference from other guns is that it is quite heavy when the battery is inserted. It might be due because it is equipped with 20 voltage, which relatively higher than the 12 volts of Milwaukee and the 18 voltage of Ryobi.

Our testers, however, thinks that the weight is a bargain for the power allowing the users to go up to 21 inches per minute (IPM) speed of the plunger.

If you think this is too fast for you, it is not something to worry because the gun has slower settings. You can turn the half moon dial to set the speed you need.

Two of the testers think that the half moon design of the speed dial is not very effective because it is a little difficult to turn. Their fingers slip several times during the testing. They suppose that it might cause delay to ones work.

With its barrel adjustments, the DEWALT DCE560B 20V MAX 10oz/300ml Adhesive Gun has Quick Connect feature to change barrel sizes. Our testers find it easier to change barrel sizes compared to other guns. They also easier to insert and change the tube of sealant.

Similar to other products on our review, this electric caulk gun has an anti-drip feature to prevent waste of sealant or adhesive. The plunger retracts to ensure that it does not push the sealant out.

There are two buttons to where the trigger is. One is the actual trigger and the other to retract the plunger. For the untrained hands, the button functions can be confusing. One of the testers accidentally pushed the trigger instead of the retract button spewing out sealant unintentionally.

What We Liked

  • Easy change of barrel and tube
  • Fast plunger speed
  • Variable speed

What We Didn't Like

  • Confusing trigger and retract buttons
  • Quite heavy

Our testers’ first impression to the Ryobi P310G 18v Pistol Grip Variable Discharge Rate Power Caulk and Adhesive Gun is that it does not seem special.

However, this impression changed when they put the gun into action.

Beginning with the battery, it had 18 volts of power and promised to finish 200 tubes of caulk before it needs to be charged. Our testers were not able to reach 200 tubes, but they have consumed one 10 oz tube during the testing and tool still has more power.

It also has five variable speed, which our testers found to be precise and consistent. There are other testers who first thought that it was not consistent, but found out that it was because the speed was too much for them. When they adjusted it, the testers were able to control the gun.

The trigger is also smooth to operate. It is big enough to fit in with any users. The testers also liked that the speed button is big with clear indicators, although they were not using numerals like the other caulk guns. It is in half circle design, but unlike the DEWALT DCE560B 20V MAX 10oz/300ml Adhesive Gun, it is bigger making it simpler to operate.

A concern that the testers have is with the dripping. In contrast to the other guns in the review, this seems to produce material even when on standby. It can waste the seal or adhesive and may also be messy in the work area. 

What We Liked

  • Powerful battery
  • Variable speed
  • Simple buttons and trigger operations

What We Didn't Like

  • Seems to produce drip when not in use


Our Recommendations and How They Compare

Editor's Pick: Milwaukee 2441-21 M12 10 oz Caulk Gun Kit

Our Editor’s Choice for this review is the Milwaukee 2441-21 M12 10 oz Caulk Gun Kit. It may not have a large oz capacity, but its overall functions and operations can be used both for homes and for industrial work.

This tool only has a 12 volts battery, though small, can yield power to finish several tubes of sealant or adhesive.

Your work is made even easy with the variable speed option for different users, which are precise. Aside from ease, it is also safe as the plunger stops pressure when not using.

Runners Up: DEWALT DCE570B 20V MAX 29oz Adhesive Gun and Mikata XGC01ZB 18V LXT Lithium-Ion Cordless Barrel Style Caulk and Adhesive Gun.

The DEWALT DCE570B 20V MAX 29oz Adhesive Gun took the First Runner-up spot. Considering the 20 volts power, 29 oz barrel, anti-drip feature and variable speed, this could have been the Editor’s Choice.

However, after serious thoughts and discussions with the testers, we want a tool that caters to all and which would be safe and durable. This electric caulk gun is deemed too large for some users, and its barrel appears to be weak. 

Placing in Second Runner-up is the Mikata XGC01ZB 18V LXT Lithium-Ion Cordless Barrel Style Caulk and Adhesive Gun. It has powerful features from 20 volts battery, to 66 IPM variable speed, and the 20 oz barrel. This falls short in coveting the first two spots due to its complicated filling and refilling.
