Tape and method to mask a structure. The tape includes a base layer having length, width, outside surface, inside surface, and top edge spaced from bottom edge. A first portion of the width of the inside surface includes a first tacky adhesive layer connected to the inside surface and located adjacent the top edge. A second portion of the width of the inside surface includes a second tacky adhesive layer connected to the inside surface and located adjacent the bottom edge. At least a portion of the base layer includes a water impermeable area that prevents water adjacent the outside surface from reaching the inside surface by passing through the base layer. And, a third portion of the width of the inside surface of the base layer includes a non-tacky area located between the first tacky adhesive layer and the second tacky adhesive layer.
