What are the differences between manual, cordless, and air-powered caulk guns?

Manual caulk guns are the most basic type, requiring physical effort to operate. They consist of a trigger mechanism that pushes a rod forward, dispensing the caulk. These are cost-effective, lightweight, and suitable for small to medium projects. However, they can cause hand fatigue with prolonged use and may not provide consistent flow. Cordless caulk guns are battery-operated, offering more convenience and ease of use compared to manual ones. They provide a consistent flow of caulk with minimal effort, making them ideal for larger projects or professional use. The speed and pressure can often be adjusted, allowing for precise application. However, they are more expensive, heavier, and require battery maintenance. Air-powered caulk guns, also known as pneumatic caulk guns, use compressed air to dispense caulk. They are highly efficient and provide a smooth, consistent flow, making them suitable for industrial or large-scale applications. They require an air compressor, which adds to the cost and limits portability. These guns are less physically demanding but require some setup and maintenance of the air system.
