Abstract: A spray shield for use at both projecting corners and recessed corners, such as in a spray painting operation, comprises an angled sheet of rigid material having integral first and second legs. The sheet has a first free edge along the first and second legs for hugging a projecting corner. The sheet also has a second free edge along the first and second legs and opposite the first free edge for congruity with or projection into a recessed corner. The sheet is slanted throughout at least one of the legs to extend at an oblique angle two vicinal surfaces of hugged projecting and congruent recessed corners. The integral first and second legs of the spray shield preferably constitute two adjacent sides of a truncated right or oblique pyramid or prism having at least one of its sides extending at an oblique angle to its base.
