What is an acceptable amount of lippage (high corners) on a ceramic floor tile installation ?
Lippage is referring to the variance in plain from one piece of tile to the other and becomes particularly objectionable when it occurs in a corner. The most common reason for lippage is that the substrate has not met Tile Council of America standards and the tile contractor has failed to point this out prior to the installation. The larger the piece of tile, the more difficult it is to compensate for an uneven floor surface. This then becomes a particular problem on canterlevered floors. It would be desirable to keep it within 1/32 (approximately the thickness of one dime), with 1/16 (2/dimes) as maximum.
