Advantages of Using Pneumatic Caulking Guns

Applying caulk manually with the manual caulking gun is very tiring for your hand and wrist. And with cordless caulking guns, there is always a chance that you will forget to charge the battery beforehand. Pneumatic-powered models make placing a consistent bead easier without tiring your hands.

You can lay down a continuous uniform bead of caulk from the beginning of the tube to the end. You can control the rate of flow and the thickness of the flow with the control knobs. You only need an air compressor and not a large one at that. These guns don’t need a lot of pressure; 90 psi ought to be enough for most. You will also need a pneumatic regulator.

Price

They are a bit more expensive than the standard manual ones. But with fewer mechanical moving parts there is less wear and tear on the system and will last longer, hence reducing the total cost of ownership. And they obviously cost much less than the cordless ones.

Precision

Some parts of the project need more precision with caulking than the other. They need to airtight for heat insulation and watertight. You need no place caulk perfectly for this to be done right. Too little will not hold the leak and too much is a waste. Set the control flow on the gun on the right settings and go on with your job. You save time and money.

Less Wastage

Precision means less wastage. Most of the time, it depends on the workmanship. But if the equipment does not have the option for you to control the flow of the amount material the caulking gun will use, even the best expert will waste lots of materials. And most pneumatic guns do have that type of control – they have adjustable regulators. This will help eliminate drips and other wasted caulk.

Work Faster

With precision work, less wastage and continuous flow of air you are only restricted by the package size of the material used which may be about 8-14 ounce. You won’t be fatigued because you do not use any physical force. You don’t have to recharge the battery like with cordless one. Just replace the cartridge and continue working.

Pneumatic guns with the ability to change the air pressure and different tips, allow you to use a wide variety of applications. This means one tool will allow you to work on your car, boat, windows, bathroom, wood projects, and anything else that would require a caulk gun.
