Caulk guns dispense caulk and other sealants into gaps and cracks to help in sealing out moisture, debris, and air. Most caulk guns operate with preloaded caulk tubes, but bulk loaders are also available. Each features an ergonomic, pistol-grip handle design with a trigger and ratcheting mechanism that applies pressure to the caulk tube in order to initiate dispensing. Dripless caulk guns stop applying pressure once the trigger is released to help in preventing waste.
