What is a paste gun?

A paste gun, also known as a caulking gun, is a tool used to dispense viscous materials such as caulk, sealant, adhesive, or grease. It consists of a cylindrical barrel, a plunger, a trigger mechanism, and a nozzle. The barrel is filled with the material to be dispensed, and the plunger is used to apply pressure to the material, forcing it out through the nozzle. The trigger mechanism controls the flow of the material, allowing the user to precisely apply it to the desired location. Paste guns come in various sizes and designs, depending on the type of material being dispensed and the desired application. They are commonly used in construction, home improvement, plumbing, automotive, and other industries.
