Recommended minimum coverage (80% for dry areas and 95% for wet areas and exteriors). Back buttering may be necessary.
Note that mortar coverage does not include backbuttering tiles. When backbuttering, consider the tile underside pattern and depth to estimate thickness
and usage to add to your estimate.
Chart for estimating purposes. Coverage may vary based on installation practices and jobsite conditions. For more sizes, use the material calculator at
