What Makes Sealant Guns So Praise-worthy?
Sealant guns are specifically developed and designed to make things easier for you. There are numerous perks of having a sealant gun in your toolkit that will make your life a lot easier to deal with.
An even finishing touch
The best thing about using a caulking gun is that it keeps everything smooth and steady. The pressure that it applies to the caulk tube divides evenly, making it easy to repair your stuff without creating uneven bumps.
Mess is not an option
Have you ever been through a situation where you had to put manual pressure on a caulk tube to fix something? But instead of fixing, you ended up scattering all the caulk on the wall? Well, it's time to avoid all such accidents because using sealant guns will keep the mess away from you.
No more hand strain
Applying caulk or sealant without a gun puts a lot of pressure on the hand because you have to use a significant force. However, a sealant gun carries most of the burden itself and does not require you to make any extra effort or exert force. This saves your hand from unnecessary pain and pressure.
What Do You Need To Keep In Mind Before Choosing the Best Sealant Gun?
A Sealant gun is a simple tool, yet it is not easy to choose the best one because of so many options. However, if you keep some key points in mind while buying this gun, you will indeed find the best one.
Which rod suits you the best?
The first thing that you need to look for while buying a sealant gun is the rod. When you squeeze the trigger on a manual sealant gun, it forces a rod into the base of the caulk tube, which in turn pushes the caulk forward. There are two types of rods:
Ratchet Rod: Using a ratchet rod can be a tiresome task as the caulk will keep coming out of the tube unless you pull the rod back. However, it is a pocket-friendly and economical way of applying sealant. If you want the gun for light projects, a ratchet rod might be a good option.
Smooth Rod: A sealant gun with a smooth rod provides a more smooth and mess-free touch. When you are done with applying sealant, all you need to do is let go of the thumb lever, which will stop the rod from pushing the tube.
Fixing your home with sealant is a tiresome task that requires your attention and skill. When using a sealant gun, your hand may slip because of sweat or moisture.
What you need to make sure of before choosing the best caulking gun is that it must have an ergonomic design. This will help you hold the gun in your hands for an extended period.
Lastly, the thrust ratio is another important factor that you cannot ignore. A higher thrust ratio means the trigger will exert more force on the tube, while a lower thrust ratio means it will apply less force on the caulking tube. If you are going to use the caulk with a thicker viscosity, you would require a gun with a more thrust ratio.
If the caulk is thin and light in texture, then a sealant gun with a low thrust ratio will easily do the job.
How Many Categories of Sealant Guns Are There?
When it comes to the types of sealant guns available in the market, there are three main types. Each of these is significant in its own way.
Manual sealant gun
This type of gun requires you to exert physical force on the trigger or the lever. Manual sealant is the most commonly used gun type. It is not only readily available in shops but is also light on the pocket. Hence most people buy manual caulking guns when they have to deal with day-to-day filling issues. There are two types of manual sealant guns, as discussed above. These are:
Ratchet Rod Sealant Gun
Smooth Rod Sealant Gun
Electric sealant gun
This type of caulking gun requires electricity to work. Plus, you do not have to exert pressure on the trigger to squeeze out the caulk. Just a light push or press is enough. They are further divided into two categories.
Electric Cord Sealant Gun: With this type, you will need an electric outlet to run it.
Battery Powered Sealant Gun: This sealant gun comes with removable batteries charged separately and do not require the cord's continuous support.
Pneumatic sealant gun
Pneumatic Caulking Gun is basically an air-powered tool that does not require batteries to charge or electric cords to function. All you need is an air compressor to make it work. These are ideal for home workshops.
Is There Any Standard Cartridge Size for Sealant Guns?
When it comes to the cartridge or the caulk tube size, the standard one is 320 ml. However, different models of sealant guns can hold varying types of tubes or cartridges. That is why whenever you decide to buy a sealant gun, keep in mind the size of your cartridge. If the tube size and the gun compatibility do not match, it will only be a waste of money.
