Caulk gun applicators dispense single-component sealants and adhesives that bond materials and fill gaps or joints between surfaces. They apply a smooth, continuous bead to minimize waste and form consistent seals. Manual caulk guns are lightweight and do not require power cords or batteries to operate. Cordless caulk guns dispense sealants with greater control and less effort than manual guns. They provide powered dispensing in areas without a compressed air supply and run on brand-specific batteries. Air-powered caulk guns run on compressed air and contain few moving parts, so they typically run cool, have a long lifespan, and weigh less than cordless guns. Accessories include components to assist with the application of caulk and support the maintenance and repair of caulk guns.
