ABSTRACT:
A pliable, resilient retaining means integrated with an area to be masked in an architectural structure, extending over and substantially covering a channel about the perimeter of the area. The retaining means is attached to the channel wall proximate the area to be masked and is inwardly displaceable, allowing for the insertion and retention of non-adhesive paper or plastic masking material. The resilience of the retaining means urges it from its displaced position outward towards the channel wall distal the area to be masked where it frictionally engages the masking sheet between the end of the retaining means and the channel wall. Placement of the masking sheet is accomplished by stuffing the edges of the sheet into the channel by running a tool along the perimeter of the channel structure, displacing the retaining means inwardly both substantially parallel and at an angle to the channel walls. The resilience of the retaining means causes it to close behind the tool, engaging the masking material and storing any excess material within the channel. After use, the material is removed and the retaining means remains in place for future applications.
