Abstract: The present invention is directed to a method of applying a rigid tile to a tiling substrate, particularly a vertical tiling substrate, such as a wall, by utilizing a double-sided pressure sensitive adhesive (psa) membrane comprising a polyolefin foam carrier coated on each side with a pressure sensitive adhesive and an associated apparatus. The polyolefin foam carrier preferably has a compression strength between 7 and 20 psi (48.3 and 137.9 kPa) @ 25%. The adhesive coated foam can be supplied in a roll form, pre-applied to the back of the tile, or pre-applied to the tiling substrate. Preferably the psa is an acrylic psa.
