Claim Text:
1. A method of manufacturing a dry adhesive backed flooring for being installed in a flat orientation on a subfloor, the method comprising the steps of: providing a roll of a sheet flooring material provided in a roll, the sheet flooring material having a first length, a first width, a decorative upper surface, and an opposite under surface; providing a roll of a double-sided dry sheet adhesive substantially free of volatile organic compounds, the sheet adhesive having a second length substantially corresponding to the first length, a second width slightly less than but substantially corresponding to the first width, and first and second adhesive surfaces, and contacting the first adhesive surface to the under surface of the sheet flooring material to marry the sheet flooring material and the sheet adhesive to yield the dry adhesive backed flooring, wherein the dry adhesive backed flooring is installable on a subfloor by contacting the second adhesive surface to the subfloor, to yield an installed dry adhesive backed flooring that is substantially free of bubbles and wrinkles and the second adhesive surface of the sheet adhesive will substantially permanently maintain the installed dry adhesive backed flooring adhered to the subfloor such that the installed dry adhesive backed flooring will remain substantially flat as initially installed and not significantly rise from the subfloor, bubble or otherwise detach from the subfloor under normal use conditions for the dry adhesive backed flooring.
