Patent ID: 7201820

Claim:
A method for protecting multiplanar structural substrate surfaces comprising at least a first substrate surface and a second substrate surface, wherein the first substrate surface comprises at least two surfaces defining at least one corner, and the second substrate surface is perpendicular to the first substrate surface, the method comprising: providing a tape strip comprising a pre-formed pressure-sensitive adhesive layer having first and second major faces, said adhesive layer having an average thickness no less than 5 mils and no greater than 100 mils; a backing layer attached to said adhesive layer first major face; and a non-perforated continuous plastic release sheet removably attached to said adhesive layer second major face; said plastic release sheet having a cross-direction (CD) tear resistance and machine direction (MD) tear resistance, whereby the ratio of tear resistances CD:MD is at least 2:1 and said MD tear resistance is no greater than 1 pound (all tear resistance values being determined in accordance with ASTM D1938); removing a first portion of said plastic release sheet by tearing said plastic release sheet in the machine direction, without using cutting string, thereby exposing a first portion of said adhesive layer; attaching said first exposed adhesive layer portion onto the first substrate surface, thereby affixing a portion of the tape strip into installation position; partially slitting a non-affixed portion of said tape strip along its length; removing the entire remaining portion of said plastic release sheet from said tape strip to expose a second portion of said adhesive layer; and attaching said exposed second adhesive layer portion to the second substrate surface, thereby affixing a second portion of the tape strip into installation position.
