    Abstract: A heat gun quickly and efficiently dries joint compound. The heat gun includes an outer shroud defining an airflow chamber and a fan which drives airflow therethrough. A motor provides drive to the fan while a plurality of heating coils disposed within the airflow chamber heat the airflow between 1200 and 1700 .degree. Fahrenheit. A fan-shaped attachment is attached about an endcap of the heat gun. The fan-shaped attachment extends into a pair of sidewall surfaces terminating in an elongated port. The elongated port is preferably between 1/2 and 3 inches in diameter and between 8 and 12 inches in length. The endcap of the heat gun is between 1 and 3 inches in diameter. A plurality of ribs connect the pair of sidewall surfaces and extend longitudinally from the endcap of the heat gun to the elongated port of the fan-shaped attachment to define a plurality of longitudinal air passages which evenly distribute airflow along the fan-shaped attachment.
