A dispensing gun is useful for many reasons. It helps eliminate mess, inconsistency and hand fatigue when applying sealing and bonding agents for various repair projects in residential, commercial and industrial settings. Adhesives and sealants can be used independently, but a dispensing gun makes the process much easier. You can control how much of the material comes out through the dispensing equipment. It also allows you to apply the material precisely where you want it to be.
Using a sealant gun or caulking a gun takes little practice. Nevertheless, the basic steps of using it are easy to learn. Using a dispensing gun effectively is essential for DIY enthusiasts, especially if they are doing home repairs or improvements. It can fill in cracks or gaps around doors, windows and bathtubs.
Cartridge size determines the maximum capacity of the dispensing equipment. The majority of dispensing guns are typically capable of holding cartridges with a 320ml capacity. Depending on the model you decide to buy, your caulking gun or sealant gun might be able to accommodate a wide range of cartridges. Some of the most common sizes for cartridges are 310ml, 400ml and 600ml. Make sure to determine the right cartridge size for your project before purchasing a caulking gun. Since the frame size of each gun can differ, without careful consideration, you may end up buying dispensing equipment that does not meet your requirements.
Dispensing equipment comes in many types, such as the following:
A manual dispensing gun requires you to use your strength to expel the material out from the tube. This type of dispensing equipment is ideal for homeowners and small construction projects.
There are two types of manual dispensing guns: ratchet rod and smooth rod.
This type of manual dispensing gun is equipped with a push rod that dispenses the material. Some of its benefits are that it isn’t pricey, it can be found in almost any store and it offers basic functionality. However, it can take some effort to dispense sealant or caulk when you use it.
Visually, this type of dispensing gun resembles the ratchet rod gun. However, this one is easier to operate and allows you to dispense more material out with less effort. It also lets you work more precisely.
This type of dispensing equipment leverages a power source rather than springs and rods to squeeze out caulking or sealant. This is a much more efficient method of applying adhesives and filling in gaps. Examples of power dispensing guns are electric or battery-powered and pneumatic.
Battery-powered guns make sealant application quick and easy. Unlike manual guns where you have to press the trigger continuously to dispense sealant, you can simply hold down the trigger in a battery-powered gun, and the sealant will continue flowing out. Consequently, this reduces the strain on your hands. Their only downside is they’re more expensive than manual sealant guns. Battery-powered dispensing guns are the best choice for those who need to use sealant guns constantly. They’re also ideal for heavy-duty use and large projects.
Pneumatic guns pump the caulk out of the tube through the power of air pressure. The amount of caulking dispensed can be controlled by adjusting the pressure via an air compressor. It can dispense adhesives, caulks or sealants rapidly and in large quantities, making it perfect for large, professional projects.
There are so many dispensing guns available today that choosing the right one can be difficult. Here are some factors to consider.
Identify the purpose of the caulk gun, and ask yourself if you plan to use it often. For one-shot projects, a no-frills, low-priced gun would be appropriate. If you’re doing home repairs or long-term projects, a more robust gun usually works best.
Guns with full-body construction are typically heavier than those with open frames. Heavy guns are also more challenging to handle, especially if you’re going to use them for hours on end. Ideally, a caulk gun should be relatively light and comfortable to hold over an extended period.
Less expensive guns generally have lower thrust ratios than more expensive guns. The thrust ratio refers to the force produced when the hand trigger is pressed. When the ratio is higher, there’s more force exerted at every squeeze.
Features to look for include finger guards and adjustable thrust ratios.
After purchasing a sealant gun, you’ll need to load the tube before using it. So how do you unlock a new sealant gun? First, locate the metal lever through which the plunger rod goes. Push this with your thumb to release the metal plunger rod. Doing so will allow you to move on to the next step: loading the tube into the gun. Â
Start by trimming the tube’s tip. You can use a utility knife to cut the end of the tube. Once the tip has been cut, you need to break the seal inside the tube to open it up and let the sealant out. Using a nail or a long screw is a common method of accomplishing this. Afterwards, you can load the cartridge into the gun. Squeeze the trigger several times so that the plunger makes contact with the tube. You may need to squeeze the tip a couple of times more to fill it with the sealant or caulk.
After setting up the sealant gun, you can now start applying the sealant. Slowly press the trigger, and maintain even pressure while moving the dispensing equipment. Once done, let go of the trigger to stop the sealant flow. Then, use your finger to smooth out the sealant.
