A sanding attachment, for use in conjunction with an existing reciprocating power tool, for sanding a rough surface of an existing object. The sanding attachment comprises a main part being an elongated strip of metal having an attachment end for selective attachment to the power tool, and a sanding end. Attached to the sanding end is a sanding pad having a sanding surface for efficiently sanding an object. The sanding attachment has a twist which results in the attachment end and the sanding end being substantially mutually perpendicular to one another. After the sanding attachment has been selectively attached to the power tool, and the power tool is held within the hands of the user is the usual fashion, the sanding attachment is suitably positioned for efficiently sanding a substantially horizontal surface.
