Caulk Guns


Dispense sealants from cartridges with ease and control.
Ratchet-action guns only apply pressure to the cartridge while you pull the trigger. They’re good for use with thin materials that require flow control. Smooth-action guns apply more consistent pressure to the cartridge, so flow continues between trigger pulls. These guns are often used with thick materials that require strength to dispense and maintain flow.
To choose a thrust ratio, consider the thickness of the material—thinner materials such as silicone and latex flow easily, so choose a low thrust ratio gun. Thick materials such as urethanes and epoxies require more power to dispense, so choose a high thrust ratio.
