        During the process of installation, the installer should
        never handle the tile by the corners, as shown in because
        the tile will take a set at the corner and will want to curl
        out of the adhesive. After an area has been dry fit, the
        installer will remove several rows of tile for application of
        adhesive. The installer must remember to place the tile
        face to face or back-to-back to prevent the sanded backs
        of the tile from being contaminated by the self-polishing
        waxy residual on the face of the tile.               3.  Urethane adhesive is remarkably like the epoxy in
