6 WEIGHT LIMITS FOR WALL TILING
The following table offers general guidance for common types of backgrounds and the maximum recommended weights for tiling.
NOTE
Where multiple substrates are installed using only adhesives, e.g. tile backer board bonded to plaster, the substrate with the lowest value will determine the recommended maximum weight of tiling. Tiling is defined as a tile plus its bedding and grouting material.
*• Provided the rendering has sufficient composition and has been installed correctly to achieve high strength.
