A surface-treating tool is configured for coupling to an extension pole with opposed proximal and distal pole ends. The tool comprises a tool head including a rigid tool support having mutually opposed tool-support upper and lower surfaces. A pole coupling configured for selectively coupling the tool support to the pole distal end is affixed to the tool-support upper surface such that a coupled extension pole is pivotable relative to the tool support about mutually orthogonal first and second pivot axes. A tool pad includes a rigid plate with plate top and bottom surfaces and a resilient layer permanently adhered the plate bottom surface. The resilient layer includes an attachment surface to which a working material may be removably attached without tools. A pad fastener introduced through the resilient layer attaches the tool pad to the tool-support lower surface with the rigid plate between the tool support and the resilient layer.
