2. Ryobi P310G 18V Pistol Grip Caulk Gun 


This model stands out thanks to its affordability, but it doesn’t disappoint in the performance department either since it has a powerful motor that delivers 500 lbs. of thrust force.

There’s no anti-drip feature, and once you let go of the trigger, the caulk in the tube will keep coming out.

Our Comprehensive Buying Guide


A caulking gun is an essential tool for all handy workers, but finding the best caulk gun is a challenge since there are so many options available on the market that knowing which one to choose can feel overwhelming.

To make the process easier for you, we have looked at numerous electric caulk gun reviews, specialized reports, and other resources to identify the key factors one ought to keep in mind when purchasing this type of product. Take a look below if you’re determined to get a high-quality electric caulk gun.

Caulk capacity

Selecting the right caulk capacity is fairly straightforward. The caulk capacity measures just how much materials the cartridges can carry in a single load. Most options on the market have a capacity of 10 oz. since this is more than enough for most applications.

However, if you are a professional that requires a sizable caulk gun, some models can carry more materials in a single go. Take into consideration the types of jobs that you plan to do with the electric powered caulk gun since while a small capacity model may be more comfortable to use, it may also need to be reloaded more often.

There are also certain models, such as the Milwaukee electric caulk gun, that can accept different cartridge configurations. For buyers who favor versatility, such a feature can prove very useful.


Thrusting force

The thrusting force is the pressure that the motor of the gun can generate to push the caulk and adhesives out of the tube. The force that an electric caulk gun Dewalt can deliver is measured in pounds.

Dense or very viscous sealants and adhesives require a higher force, while less viscous materials will be dispensed easily even by low-powered products. For slightly viscous materials, a gun that delivers around 400 lbs. of pushing force is more than enough.

Moderately viscous materials will require a Dewalt electric caulk gun that can deliver at least 500 lbs. of pushing force. Lastly, for highly viscous adhesives and sealants, customers should switch to a premium electric caulk gun Milwaukee or other reputable brands produce since for these tasks you’ll need at least 1,000 lbs. of pushing force.



The best electric caulk guns are those that can lay a straight bead of the same diameter, and for this to be achievable, a constant flow of material is needed. Even cheap electric caulk guns have the upper hand over a manual model in this department since the motor allows for a continuous output that facilitates a constant flow of caulk materials.

However, if you want to enjoy increased precision, you’ll need to invest in a product that comes equipped with a speed control feature. This is an essential feature since it lets the operator regulate the amount of caulk that comes out of the cartridge.

Different jobs require different outputs of sealant since, for example, when performing a precision joint, you only need a small amount of material. Having control over the caulk flow rate makes it possible to achieve accuracy and clean beads. Furthermore, it can also help prevent under and overconsumption of caulk materials.

This is a feature that often can’t be found on a cheap electric caulk gun, but most models from reputable brands such as Dewalt, Milwaukee, and Ryobi have it.


Sturdiness and durability

A cordless caulking gun should be constructed of high-quality materials so that it can still serve you for years to come without breaking. However, it can be difficult to judge the quality of a product just by looking at it, especially when purchasing online where your first contact with the product happens well after you’ve made the purchase.

Pay close attention to the product page to see what materials the unit is made of. The tool should ideally be made of light steel or aluminum since these materials offer increased strength and durability without adding too much extra weight.

It is possible to find affordable electric caulk guns made of plastic that can still deliver excellent durability, but if possible, it is always advisable to stick with a product that’s made of metal.

If the manufacturer doesn’t mention what types of materials its tool is made of, a good way to get an idea of the sturdiness and durability that the unit offers is to read an expert electric caulk gun review. You may also gain more information by taking a quick look at the customer feedback section.

Comfort and weight

A cordless caulking gun is perfect for prolonged use, but for a product to deliver improved comfort, it needs to come with a soft grip. Other features that can help improve comfort and make using the unit more convenient include having a trigger lock, a loading indicator, and an anti-drip guard.

The weight of the unit is important as well since compared to manual caulking guns, a Ryobi electric caulk gun will feel much heavier in the hand since the tool needs to accommodate a battery and a motor. Both of these components can be quite heavy.

This is why it is important to invest in a product from some of the reputable brands we’ve mentioned earlier since they have done a lot of research and experimentation to keep the weight of their products as low as possible.

If a tool is too heavy, it can become burdensome and slow you down. Weight shouldn’t be a disqualifying factor, but if you plan to do jobs that require you to operate the gun for long periods and in difficult positions, then you’ll need to take weight very seriously.



Frequently Asked Questions:


Q: Can a person with arthritis use electric caulk guns?

The main appeal that electric caulk guns have is the superior comfort and ease of use that they offer. This means that everyone can use them, including people with arthritis or users who find it difficult to grip a manual caulk gun. However, not all electric caulk guns offer the same level of comfort.

For starters, you need to consider the weight of the unit, and we recommend going with a product that boasts a compact and lightweight construction. To achieve optimum comfort for people with arthritis, the caulk gun should not weigh more than 4 lbs. with the batteries and all the other accessories attached.

The quality of the grip handle is important as well since it is the part of the unit that your hands will interact with the most. Look for models that feature a handle made of very soft materials. The gun also needs to be balanced properly so that its weight doesn’t cause your hand to shift from one direction to another.

Q: How do you stop caulking from coming out of a gun?

The easiest way to stop the caulking material from coming out of the gun once you release the trigger is to purchase a dripless option. Most electric caulking guns on the market have what’s usually referred to as a drip-free feature. This feature is designed to reduce the pressure on the cartridge once the user releases the trigger.

A drip-free tool can make the job easier for both professional and casual handypeople since it reduces excessive and messy dripping. If you have a Dewalt caulking gun, you probably already have this feature. However, if you’ve purchased a product that lacks this feature, you should make sure to press the release trigger quickly after applying the caulk.

For any excess caulking material, you can use a wet rag or a paper towel to clean and smooth out the caulk lines. Furthermore, the more that you use the tool, the easier it will become for you to develop a feel for the flow and achieve consistent and steady beads.


Q: Should you tape before caulking?

If you want to achieve professional results, then it is certainly advisable to prepare the area for caulking before you apply the material. This is even more important for indoor jobs, such as in the bathroom, where it is easier to notice imperfections. Start by purchasing painters or masking tape, both of them work for this purpose.

The next step is to take the time to look at the line that you want to caulk and apply a piece of tape on both below and above the line so that you have around one-eighth of an inch of space on both sides of the crack. This will help make your caulk lines more aesthetically pleasing, and it makes it easier to clean the workplace once you are done.

However, you shouldn’t remove the tapes immediately once you are done caulking, but rather you should wait until the caulking material has dried to the touch.
