What is a caulking gun and what is it used for?

A caulking gun is a tool for the clean and controlled application of sealants, adhesives or silicone from standard cartridges. It is often used in the construction, sanitary and DIY sectors.

What types of cartridge guns are there?

There are manual, battery-powered and compressed air-powered cartridge guns. Manual models are the most common, while battery-powered and compressed air-powered models have been developed for professional use.

What does the power ratio of a cartridge press mean?

The force ratio describes the ratio of the manual force applied to the actual pressure force on the cartridge. A higher ratio makes it easier to work with viscous materials, as less force is required.

What advantages do high-quality cartridge guns offer?

High-quality models have a better force ratio, making it easier to process viscous materials. They enable even dosing and require less effort.

Which cartridge sizes fit into a cartridge gun?

Standard cartridge guns are designed for 310 ml cartridges. However, there are also models for larger or special cartridges.
