A powder coating booth containment structure including first and second canopy halves, each of which is a substantially nonconductive, seamless, structural composite to substantially reduce oversprayed powder particle adhesion to the booth inner surfaces. The composite canopy halves, when assembled into a spray booth additionally including either a floor or a utility base and one or a pair of end units in the form of aperture bulkheads, vestibules, or a combination of both, are structurally sufficiently strong that no external support frame is required. The composite canopy halves can each include sidewall and ceiling portions, in an embodiment, that can be connected to a floor. In another embodiment, the canopy halves each additionally include a floor portion such that they may be connected together at a floor edge and placed atop a utility base. They may be connected to the utility base. In another embodiment, the canopy halves may each further include an integral end or ends, comprising aperture bulkhead or vestibule-type end portions. Methods of assembling these embodiments are also provided that require less time than for known powder coating spray booth assembly. In another embodiment, a conductive material is incorporated into the composite structure to bleed off charge or repel like charged particles generated during or after a spraying operation.
