ABSTRACT:
The present invention is a hand held tool for removing coatings from a substrate. The hand held tool includes a housing having a front section with an outlet, a mid section with an inlet, and a rear section, a heat source disposed within the front section of the housing for emitting heat through the outlet, and a vacuum source disposed within the mid section of the housing for providing suction through the inlet. The hand held coating remover further includes a power source disposed within the rear section for supplying power to the heat source and the vacuum source, a control panel having a heat controller for adjusting and controlling the heat emitted from the heat source through the outlet and a vacuum controller for adjusting and controlling the suction provided by the vacuum through the inlet, and a blade located adjacent to the inlet and resiliently coupled to the housing. The coating is safely removed from the substrate by first heating the coating, moving the blade across the heated coating to scape the coating, and vacuuming the coating as it is scraped or removed from the substrate. Also, any fumes that are created when the coating is heated is easily removed by the vacuum.
