I am not quite that inflexible but not far off. Everybody knows what you can do and what you can get away with and personal judgement etc but i just made a conscious decision to have a cut off point and that's mine nowadays. It just gives me an easy line to work with if i'm doing a rip out and don't know what's behind the current tiles, i quote the numbers to the customer and they either accept them or not before i even get the jobI have to admire your inflexibility but in my humble opinion it is OTT hardi backer has been tested and it will hold four ton but they set a limit of 100kg so with your inflexibility if the tile come in at 101kg you have to walk away.
