Abstract: A masking device for caulking, painting and similar operations includes a strip of material with multiple perforations. One side of the device may be provided with adhesive over desired areas. The adhesive may vary in strength along various regions of the surface. In use, the device is placed over the area to be caulked, painted or similarly treated. A desired portion of the masking device is peeled back and the desired operation is performed. The remaining portions of the masking device are then removed. In another embodiment of the invention, the device utilizes multiple strips, at least one of which partially overlaps another.
