A paint shield to enable one operator to efficiently and effectively spray paint interior room corners. The paint shield includes two rigid sheets of material which are joined in a perpendicular orientation. The angle of this joint matches the angle of an interior room wall to wall corner. The paint shield also includes an elongated handle mounted between the sheets and angling away from the joint. The handle may have a telescopic capability. The handle may also be positioned closer to a particular wall. The angle of the handle allows ambidextrous use of the paint shield, while providing unhampered excess for spray painting the ceiling or floor corner. A painter may single handedly hold the shield against a wall corner, while spray painting the exposed ceiling or floor and effectively masking the protected wall surfaces.
