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.
Guns with an adjustable thrust ratio let you use the same gun for sealants and caulks with different consistencies. Use a higher thrust ratio to evenly dispense thicker, more viscous sealants and a lower ratio for thinner sealants. Guns with a dual cartridge capacity give you more time between refills and let you mix two-part compounds.
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.

Drip-Free Caulk Guns
Minimize mess and waste—when you release the trigger on these guns, the rod retracts slightly to reduce pressure, which stops flow from the sealant cartridge.
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.

Adjustable-Flow Air-Powered Caulk Guns
Adjust air-flow for precise control and smooth material flow—these guns have a built-in pressure regulator with a control knob.
Bulk-load guns apply sealants from pails and drums. They work like syringes—immerse the nozzle in your sealant and pull back the rod to fill the gun.
