Caulk tube is more or less useless without a caulk gun, you can’t have that continuity and uniformity any other way. Sometimes the thin barrier between calamity and serenity is by the virtue of these caulk guns. Am I blowing this out of proportions? No, leaks on the window during a stormy winter will bring hell.

Now, let’s simulate someone using a caulk gun with his bare hands. He’ll be creating beads of the caulk, everything will become a mess. Fingers will eventually drown in that caulk. Why go through all this sticky trouble for the sake of a couple of dollars. Keep your caulk tube in the safety of the best caulk gun.


Caulk Gun buying guide

Wait a second. Do you think choosing the perfect caulking gun is everyone’s piece of cake? No, dear! I’ve gone through those horrible experiences that I invited by choosing the wrong one. But you need not bite nails. I along with some fellow experts have researched this topic ‘n came up with solutions. Here’s a shortlist:


Ratchet or Dripless?

A ratchet-type caulking gun is less efficient than dripless guns as the former requires more energy and provides less control. In the case of ratchets, once you push the handle, the flow of the caulk tends to move on. This flow won’t stop unless you push the rod upside down. This surely depicts the inefficiency as you need to be flawless in stopping the process.

The standard thrust ratio you can have by this type is 5:1. This ratio is exactly half or even less than the dripless ones. But the only good thing about this type is the cost. Simply the ratchet ones are less costly than the dripless ones.

On the other hand, the use of a dripless caulking gun is more effective. They can apply caulk more efficiently because of the design. The mechanical advantage you can get is simply double or even more. Along with some additional features, they have proved more ergonomic. That’s why the dripless caulking guns are thriving currently.

Build Quality

If you encounter a caulking gun that is made of steel, it will be heavier. But if you find a gun, made of composite materials, it will be lighter. The steel ones are better options for heavy-duty caulking for a long period. But the composite material built may face some cracks.

Besides, the build quality will differ by the handle or by the barrel design. Full barrel design neither helps in lowering the weight nor eases caulk application procedure. So always go for half barrel design.


Suppose you need to do caulking at this moment but you don’t have any cutter with you. But the caulking tube is sealed tight. What will you do? The manufacturers have realized this fact and that’s why they have attached a spout cutter with the gun. Now you can cut the tip of the caulk and thus can get rid of the problem.

But there’s a problem. You can’t find this cutter in all guns. Some manufacturers cut off this feature because of cost-saving reasons. But if the budget is not a problem, you should go with a gun which has a spout cutter.

Wired rod

Another cool feature is the tiny attachment which is attached near the caulk-releasing end of the gun. This is basically a hardened wire to break the seal of the foil that is attached to the caulk tube. But, unfortunately, this is an extension that can only be found in high-end caulking guns.


Probably it’s the most important part while you’re applying pressure on the caulking gun. The handle will ensure that the caulking tube attached in the gun gets the proper pressure through the plunger that’s required to eject the right amount of caulks.

To make it comfortable enough the manufacturers choose to provide a soft grip on the handle. Having finger indents on the handle makes it more ergonomic. Besides, the handle itself should be lightweight. It’s preferable to use a handle that is made of using aluminum. Besides, aluminum will ensure further durability by preventing rust on its surface.

Best Caulk Guns reviewed

Buckle up! Now I am going to present before you the list that I have made after some rigorous tests I’ve conducted. As you can guess our combined experience has played the trump card while creating the list. I’ve jotted down the upsides along with the negatives of each product in the list so that you can get a clear conception about it. Let’s check out!

1. Newborn 930-GTD Caulking Gun

Why this?

To begin with, we’ve chosen a tool that can blow your mind. It’s a dripless caulking gun from the renowned manufacturer newborn. With sturdy construction and high build quality, it’s ready for the heavy push to pay under the tube of the caulk.

If you’re a hobbyist, or simply want a caulk gun for your next DIY project, you can go for the single pack. But if you own a shop or a heavy workstation, meant for industrial-grade operation, you can go for three or four packs. Good for your pocket!

You know, the standard cartridges of caulk are of 1/10-gallon. So, the manufacturer has made the gun fit to handle the standard options. This gun features a half-barrel construction (also known as a cradle). This part of the gun is made of steel for enduring excessive load and also for enhanced durability.

You got a thrust ratio of 10:1. That means whatever pressure you render as input, the output pressure will be 10 times higher. This construction is good for dealing with low viscosity material.

The pressure rod is also designed to work with less force and that’s why it is quieter than ratchet ones. Most importantly, the handle and trigger are covered with soft padding to ensure comfort.

What we didn’t like

  • The rod doesn’t rotate along the axis.
  • That’s why you may face difficulties to ensure a proper clean of the tool.

2. Dripless Inc. ETS2000 Ergo Caulk Gun

Why this?

At first, the sturdy construction of the mighty tool comes to play. The primary build material is composite materials. As you know, the manufacturers use plastic, nylon or even fiberglass to create a composite. That’s why the structure is so strong and can endure much pressure.

No difference for this caulking gun. You get a longer service life even if the tool has to face heavy loads.

This time the manufacturer has introduced its renowned and reverted grip in this caulk gun. They’ve put a great effort to make the grip more sophisticated to the user. That’s why you can see a superb grip on the handle. While applying the caulk into position, you’ll find it handy to have better control over the caulking gun.

The rotating barrel is introduced to put the caulk into the exact place. Another benefit of the feature is you can access hard-to-reach areas of the tool while cleaning it.

And who doesn’t know proper cleaning is the basis of the longevity of any tool? With the sharp precision cutter, you can open the caulk in moments. Above all, the caulking gun is 40 percent lighter than metal models. That’s why comfortable use is guaranteed.

What we didn’t like

  • If you need to hang the gun with the caulk tube loaded in a vertical position, you may experience that the caulk tube doesn’t stand still, rather slips.
  • Besides, the tip cutter is not perfect to render a flawless cut.

3. Dripless 10oz Caulk Gun

Why this?

Another great tool by Dripless, back to back! The manufacturer has made a wide range of caulking guns for different purposes. If you’re up to a heavy paint job, plumbing or anything like that, you can check out this sturdy tool.

This time the manufacturer has given the option for 2’s, 3’s or 5’s pack. Of course, if you purchase more than one, it’ll be more convenient for you to maintain a shop or industry level work as you can still have the same quality in different tools.

This tool is also constructed from composite material like the previous one. It means the manufacturer has chosen the same material made from nylon, plastic, and fiberglass to build the primary structure of the tool’s body. Lightweight with durability is ensured!

You can have an 18:1 thrust ratio. It means you get a massive force on the caulk tube for heavy-duty caulking. To handle this massive load, it has redesigned the rod and also the drive dog.

For this model, they have used metal powder reinforcement. That’s why increased durability is guaranteed. Besides, the handle is covered with a soft grip to ensure superior comfort.

What we didn’t like

  • The body is constructed with a so-called composite material. But the problem is this construction has a tendency to crack and that’s why you may experience minor cracks if you drop it from a certain height.

This design is essential for a professional-grade tool to sustain for a long period.

The manufacturer gives a scheme of money back. Suppose you purchase the product today and not be fully satisfied, you can give that product back to the manufacturer. You can enjoy this scheme for an entire year!

What we didn’t like

5. Edward Tools 10 oz Caulk Gun

Why this?

With its iconic half barrel design, it can hold the caulk tube up to 10 oz. If you are up to plumbing, painting or sealing, you can definitely have the benefit of this caulking gun through its better ergonomics ‘n solid build quality.

Let’s move towards the build quality of the tool. No wonder that the manufacturer has chosen steel as the primary build material for the tool. We know the power of steel as a material that can sustain the heavy load.

When you apply pressure on the rod, you actually make the body of the gun to endure the force. That’s why steel is a better choice as this construction will be helpful for longer life.

The manufacturer has designed the gun to be able to deliver more pressure, even in case of less input pressure. The dripless design has been introduced to ensure more output pressure. Besides, the rod will automatically retract after the use. That’s why you’ve to pay less effort to obtain a mighty trust.

Simplicity and better ergonomics are ensured while designing the tool. All the components are designed to encounter less friction and to give maximum pressure on the caulk tube. As the tool features better build quality and solid design aspects, you have a lifetime warranty for the tool.

6. Tajima CNV-100SP Convoy Rotary Caulk Gun

Why this?

Tajima has brought a caulking gun that can please you by its different features. You can get it in two different variants. One is 1/10-gallon and another is for its half capacity. That’s why you can get the same quality in different sizes!

To examine the body construction of the tool, we’ve checked the frame of the gun. The frame is built with steel. That’s why you get durability. But the coolest fact is, this caulk gun is lighter than other steel counterparts. This construction has enabled the tool to be a more effective performer as you can control the tool with ease.

If you’re a pro in this field, probably you’ve noticed how difficult it is to load the caulk tube inside the gun. Well, the main reason behind this is a design error. You know that the ratchet-style guns are oldies. Besides, the aging of the tool can also make it hard to load. But for this gun, simple loading is guaranteed.

A stronger aluminum handle has empowered this gun to create more thrust on the caulk tube. As aluminum is used, the handle itself is lightweight but strong enough to endure pressure for a long time. For ensuring the smooth flow, twin thrust plates are also introduced.

What we didn’t like

  • You won’t find any cutter in this gun. That’s why you’ll need to arrange a cutter all by yourself.
