This means it has limited functionality. Based on the material used for construction, the operational life is limited too.
Many models are labeled as dripless nowadays, but this caulking gun is truly dripless. But that’s not all, this model can accommodate both dripless and drip-only settings. Some people prefer the drip setting because it allows them to get the best bead orientation which is crucial when working around corners. On the other hand, some might prefer the non-drip setting.

5. 3 in 1 Caulking Gun (HEAVY DUTY CHROME PLATED) – Suitable For Big Repairs

It comes in industrial design, so the frame is made from rust-free heavy-duty plated chrome which ensures the durability and strength of this tool.

It is advertised as suitable for home and industrial use, but we can’t agree with that.

Key Factors To Consider When Choosing A Caulking Gun
Usually, the caulking gun is something that most of us infrequently use for small reparations or our DIY projects. If that is the case in your household, then you should not spend some serious amount of money on it. But, that does not mean you do not need to spend a little more time considering which model you will purchase since they can be convenient around the house. That is why we recommend you to read our buying guide.
1. The Rod
When using the manual caulking gun, the rod is something you must check first. When squeezing the hand trigger, the caulking gun forces a rod into a tube of caulk, which results in the caulk being pushed out the tip of the tube. There are two types of caulking gun rods.
- Ratchet rod – Caulking guns with ratchet rods are inexpensive and suitable for home use and light DIY projects. The problem with this type of rods is that the sealant will ooze out as long as you don’t twist the end of the rod and pull it back to release pressure and stop the flow. This way, the application is messy, and you will waste a significant amount of sealant.
- Smooth rod – This type of rod is a bit neater than the previous one. The models that are advertised as dripless come with a smooth rod. They are called dripless since the gun should stop the flow of the adhesive the moment you release the trigger. This works better in theory than in real life, but some do offer you a dripless application.
2. Thrust Ratio
- Thrust ratio expresses the amount of force you generate every time you squeeze the hand trigger. The higher the thrust ratio, the more force is used with each squeeze. This is crucial since different types of sealant have a different kind of viscosity.
- Thicker sealants require the use of the caulking gun with higher thrust ratio to be able to dispense the sealant like epoxy, or acrylic. A thrust ratio goes in the range from 3:1 to 28:1. Guns with lower thrust ratio are suitable for dispensing thin types of caulk, such as water-based caulk, latex caulk, silicone, and latex.
3. Revolving Frame
- Revolving frame is important since it will prevent forming lumps and bulges when running a bead of caulk, especially around the corners. It is very challenging to run a continuous bead around a corner considering you must change the hand position and the angle of the gun to match the direction of the sealant. The revolving frame will allow you to rotate only the frame instead of the whole gun; this way, you do not interrupt the flow of caulk.
4. Powered Or Manual Caulking Gun
A manual caulking gun is suitable for a smaller home and DIY projects. If the design is not ergonomic, you will experience hand fatigue very quickly. Also, they aren’t dripless so if a messy workplace annoys you, consider buying a powered caulking gun since they come with Anti-Drip feature.
A few years ago powered caulking guns were reserved for commercial and industrial projects only. Today, DIYers are discovering all the benefits of using a powered caulking gun. They dispense the sealant in a continuous stream, so they create a smooth bead. Also, there is no hand trigger, meaning there is no thrust ratio.
To regulate the dispensing pressure, all you need to do is lightly squeeze the finger trigger. Your hands will be grateful. You also must be aware that this type of caulking gun is a bit expensive. There are three different types of powered caulking guns.
- Electric – They come with a cord and require access to an electrical outlet, so they can be tricky to use outside. With light pressure on a finger trigger, you will dispense just the right amount of sealant every time.
- Battery Powered – This type of gun features a removable battery and a charger. They are suitable for use where the electric outlet isn’t available. Typically battery life is up to three hours per single charge. We recommend you to purchase an extra battery if you have a lot of caulking to do.
- Pneumatic – The most popular powered options for home and workshops are air-powered caulking guns. There’s no battery to charge, electric outlets and cords, but you will need an air compressor. Also, dispensing pressure can be regulated by adjusting the pressure on your air compressor, which can be very handy.
Which model is the best and the most affordable caulking gun, strictly depends on you and your budget. Today we have assembled a buying guide for you with some of the models that we liked the best. In the end, if none of these five models matches your requirements, you are free to continue searching.
