Abstract

A powder coating booth and a construction method therefor comprise a pair of inflatable polymer walls defining between them a booth inner space, a booth entry end and a booth exit end, and supporting the inflatable walls in spaced orientation to define between them the booth inner space. A mechanism is provided between the walls for recovery of powder which does not adhere to articles conveyed through the booth inner space. The polymer walls comprise one or more cells. The step of providing the polymer walls comprises inflating the cells. The method also includes the step of covering the cells with a sheet of polymer film forming an envelope for the cells. Illustratively, the cells comprise a layer of bubble packaging material. Alternatively, the polymer walls comprise thermoformed cores and a polymer film envelope enveloping each core and closed to provide suitable inflation of each wall. Illustratively, the inflatable walls are supported in spaced orientation by a conventional powder spray booth. The inflatable walls are mounted to inside walls of the conventional spray booth by, for example, synthetic hook and eyelet material.
