Perfect for the application of any sealant or silicone, caulking guns, also known as silicone guns, are essential for the laying of linear sanitary joint or gluing in primary or lighter work. Manual or electric, the caulking guns dispenses sealant and silicone!
- Rachet Rod
What are the advantages and disadvantages of the rachet rod caulk gun?
Due to its mechanical operation, the rachet rod caulk gun is autonomous and will not leave you in short supply in the middle of a job. Its simple mechanism also assures a flawless reliability. Its low cost and robustness are also major positive factors.
A certain dexterity is needed when wielding it to produce a consistent line with roughly the same diameter. Since the consistency and the amount of discharged caulk is based on the pressure exerted on the gun, irregular pressure will result in a lopsided line! For this reason, it is sometimes difficult to properly judge the amount of sealant needed.
In case of low temperature, the sealant or silicone will expand, forcing you to exert even more pressure.
If your gun is of poor quality and you stubbornly continue to push on it, its cradle might bend or the rod could fall out. In this case, rather than continue any unfruitful attemps to force it, simply heat your sealant or silicon. It's a much better solution that damaging the gun and wearing out your arms!
What are the advantages and disadvantages of the electric caulking gun?
Three key words would qualify the electric caulking gun: precision, efficiency and comfort.
To succesfully lay joint in a straight line and of the same diameter, a constant flow of silicone is needed, so a lower or higher pressure must be exerted to alter the width of the line. The electric gun, allowing for a continuous and regularoutput, facilitates this type of implementation.
Only a small amount of sealant is needed to perform a precision joint or a low volume seal. The electric caulk gun, offering adjustableregulators, directly doses the amount of sealant or silicone output. No more under and over consumption.
The electric caulk gun is perfect for prolonged use or for those who have a soft grip! You can also add more handy features:
- A trigger lock ;
- A provided needle for unclogging cartridges;
- An anti-drip guard;
- A loading indicator.
How to choose the battery for your electric caulk gun?
There are three types of batteries.
Ni-cd: nickel cadmium
Nickel cadmium represents the old generation! This battery is heavy and takes a long time to charge - not every time, but often enough. This type of battery features the memory effect: if a load is prematurely stopped, the component believes that it has reached its maximum charge and defaults to this value on the next charge. When done repeatedly, you end up with a battery that can no longer hold a charge. The nickel cadmium is more often used in basic models. Recent trends show it disappearing in favor of Lithium-Ion batteries. It is also highly recommended to let these batteries discharge completely before recharging, and remove them from chargers once fully charged. These batteries have a large number of charge cycles.
Li Ion: Lithium-Ion
The ultimate choice! This battery is light, recharges quickly - in about an hour and a half - and has no memory effect. A Lithium-Ion battery will give everything it has - or almost - until its dying breath, which can be tricky if there is no charge indicators. Lithium-ion batteries are powering more and more tools, maximizing both efficiency and comfort for the user.
Stands for nickel metal hybrid. Behind this mouthful of a name hides a rather heavy battery - weighing more than the nickel cadmium battery - and with a slight memory effect. This type of battery has fewer charge cycles than nickel cadmium - 3 times as less.
The choice of any tool must first be based on its requirements and needs.
The electric caulk gun is so accurate that for this reason alone, its a solid choice, especially if your work requires it.
If, on the contrary, you only are laying down a rough caulk, and using your finger to smooth and seal the joint, you may only consume one cartridge or two a week, in which case a rachet rod caulk gun is sturdy and has less chance of breaking if it falls off a roof!
Keep in mind that electric caulk guns are electronic devices and are totally dependent on their battery and their craftmanship. They are also more fragile and will quickly be noticed if left behind on a building site.
The rachet rod caulk gun has little to be jealous over, it is inexpensive yet durable and will lead to impressive forearms with regular use!
When you're done, simply allow a bit of sililcone to seep through the nozzle, so as to avoid damaging it by having to unclog it with a sharp spike.
