Abstract
A self-adhering walkway pad (20) comprises an elastomeric pad having upper and lower surfaces (21, 22) and a 100 percent solids tape (25) pre-applied to the lower surface of the pad, prior to use in the field. A method for applying walkway pads to roofing membranes comprises, affixing a 100 percent solids tape to one flat surface of a walkway pad, prior to use in the field, the opposite side of the tape carrying a protective layer of release paper; stripping the release paper from the tape immediately prior to use; subsequently placing the exposed surface of the tape directly onto the upper surface of the roofing membrane and, applying force directly to the walkway pad to enhance the bond between the pad and the membrane, created by the tape.
