A loop of elastic material adapted for removable placement about the handle body portion of the paint brush at the base of the bristles is U-shaped in cross section to define an outwardly open trough for catching excess paint which might otherwise flow down or drip from the brush handle. The elastic loop is provided, at opposed end portions where passing around the arcuate end portions of the brush body, with interior spacer strips maintaining mutual parallel spacing of the opposed legs or sidewalls of the elastic loop which define the trough.
