ABSTRACT:
Apparatus for isolating an area of a surface to be spray painted, and preventing the spray from coating adjacent areas thereof. A pair of inclined, diverging walls are supported near one end thereof by a transverse support, leaving an elongate slot between convergent edges of the sides. A resilient pad extends beneath each of the sides and adjacent the slot for contacting a surface to be painted. In a preferred embodiment, the transverse support is curved inwardly, and a hand grip is provided. When held against a surface and a paint spray applied to the region of the slot, the inclined walls deflect the spray adjacent the slot upward and away from nearby surfaces while the resilient pads serve to sealingly define the edges of the area to be coated. The curved support near one end of the slot forces overspray blown toward it to be deflected lengthwise along the slot, away from the area in which a spray apparatus may be positioned.
