Abstract
A spray box provides a portable enclosure through which trim, molding, and other boards may be passed for spraying with a liquid coating such as stain, paint, or varnish. A board enters a passage aperture at one end of the spray box, is sprayed by spray nozzles provided in the spray box, and then exits a passage aperture at an opposing end of the spray box. Rollers transport the board through the spray box, wherein excess spray is collected at a drain hole and recirculated back to the spray nozzles for reuse.

A portable spray box comprising:
- a. a box floor having opposing box floor sides spaced by opposing box entry and exit floor ends, the box floor having a drain hole therein;
- b. a pair of box sidewalls rising from the box floor sides, the box sidewalls being split along their height to define:
- (1) an upper spray box portion including the box roof, and
- (2) a lower spray box portion including the box floor;
- and wherein the upper and lower spray box portions are hinged together at one of the box sidewalls;
- c. a box roof extending between the box sidewalls above the box floor, the box roof having spray nozzle apertures defined therein;
- d. a board passage extending through the spray box between the box entry and exit floor ends and between the box floor sides, and below the box roof and above the box floor;
- e. support rollers situated along the board passage, the support rollers being placed and oriented to translatably support boards passing through the board passage;
- whereby spray nozzles may be situated in the spray nozzle apertures, and a board may be placed on the support rollers to roll through the board passage to receive spray from the spray nozzles.
