A spray coating booth for enclosing individual articles to be coated with a liquid spray while the articles are supported in closely spaced relation on an article conveyor for movement through the booth includes a rigid frame with fixed sidewalls and movable top and end walls which may be moved between a closed position completely enclosing an article supported on the conveyor and an open position to permit articles to be moved into and out of the booth. The movable top assures against coating liquid dripping onto and contaminating articles moving on the conveyor which are not to be coated. The end walls are supported for movement in substantially a transverse vertical plane to permit close spacing of articles on the conveyor without contact of the articles by the end walls.
