You wouldn’t suspect that there’s such a vast difference from one caulking gun to another but there really are a lot of things that can vary from one model to the next. Let’s take a look at some of the key things you should be aware of when shopping.
Obviously, the more durable the material, the longer the caulking gun will last. Most of these are made from strong materials like steel or aluminum, which are great because they will last a really long time.
This tells you how much caulk the gun can hold before you’ll need to reload. If you’re a professional who tackles grout a lot, it might be worth it to invest in a larger barreled caulking gun. That will mean less reloading and longer periods of being able to work uninterrupted.
In order to contain drips, caulking guns have to be able to pull back a little at the end of each trigger pull to stop extra caulk from coming out. Because of this, only smooth release caulking guns can be dripless. Ratcheting guns are designed to increase pressure with each click so there’s no real way for them to pull back.
Some caulking guns will claim to be dripless but keep in mind that drips can happen with any gun, at any time. A lot of things affect whether or not a gun will drip so just because you’re using one that says it’s dripless doesn’t mean you’re in the clear. Technique has a lot to do with it.
Thrust: Pressure Ratio
This is also referred to as “thrust ratio” or even just “thrust”. You’ll see this figure with manual caulking guns. (Battery powered guns are rated a little differently.) This ratio will be something like 12:1 or 26:1. What it’s telling you is the ratio of 1 pound of pressure applied by the user to how much pressure is applied by the caulking gun. So, a ration of 12:1 means that for every 1 pound of pressure you squeeze, 12 pounds will be applied. Or, 26:1 means for every 1 pound of pressure you apply, 26 pounds will be applied by the gun.
Here’s why this matters. Caulking guns that apply a lot of pressure can be used with thicker materials. Think about it this way. Say you have different materials you want to use in your caulking gun. One is the consistency of water and the other is like maple syrup. It’s going to take more pressure to push the maple syrup through the gun than the water. Now, imagine that instead of maple syrup, you have something the consistency of honey. You would need even more pressure.
Caulk can be made out of a lot of different things, from latex to silicone that have different viscosities. So, consider the kind of adhesives, sealants, and caulks you’ll be using and make sure to choose a gun with a pressure ratio that can handle it.
On battery-powered caulking guns, thrust is measure in Lbf or pounds of force. That’s because there is no manual force being applied, only what the motor is capable of. This figure varies a lot from model to model, too.
Manual or Battery?
Manual tools are usually enough for home use but if you’re a professional who does a lot of big jobs, a battery-powered caulking gun really makes life easy. They’re not only faster but they are often more consistent and provide better-looking uniform results.
One thing to keep in mind, though, is that battery-powered caulking guns are a lot heavier than manual ones. This is mostly due to the weight of the battery. If you’re planning to do a lot of overhead work, weight the pros and cons very carefully before making up your mind.
Also, keep in mind that some battery powered tools come without the battery or charger included. Major tool brands have battery systems that can be used interchangeably between different battery operated tools within the brand but this only comes in handy if you already have a battery and charger that works with that specific brand.
Some caulking guns come with some little extras. An integrated hook is a nice thing to have because it allows you to hang your caulking gun off the ladder when you need both hands to finish the job. This is particularly important if you’re working on a ladder, obviously, and it also comes in really handy when it comes time to store the tool.
Another convenient thing some caulking guns have is a puncture tool to open caulk easily. This is a really cool thing to have because it saves you from having to fumble with a pocket knife or other tool when you have to open a new container of caulk.
Now that you know a little bit more about the important features of caulking guns you can choose the one that best suits your needs. Remember, it helps to have an idea of what kind of material you’re going to be using so you can get a caulking gun with the right amount of thrust.
