ABSTRACT:
A heated caulk dispensing gun for dispensing sealant from conventional cylindrical refill cartridges in cold ambient temperature conditions includes an elongated semi-cylindrical base having a mating semi-cylindrical cover mounted for pivotal movement by a hinge. A ratchet mechanism actuates a plunger rod for incrementally dispensing contents from a refill cartridge upon manual activation of a pivotal trigger lever. An electrical resistance heating element lines the base and cover and is connected to a thermostatic control for maintaining a predetermined temperature level. A power cord is connected to the heating element for providing power from an external source.
