ABSTRACT:
A mobile paint application and microwave drying apparatus has a downwardly open hollow frame forming a microwave cavity movable over a surface on rollers. The interior cavity of the frame is coated with microwave absorbent material, as are the rollers. The frame in the front and rear conforms to the rollers with a certain gap and ends above the surface at a certain distance. Treads extend between the front and rear rollers on each side and have a thickness which is greater than the gap and distance so as to create a circuitous path from the cavity which blocks microwave radiation. A paint spray nozzle is located in the cavity and applies paint to the surface. This paint is rapidly dried by a microwave generator which is positioned in the cavity and directs radiation onto the wet paint.
