Which brings us back to the classic (and in my experience - increasingly regular) dilemma. Customer has bought 12mm thick travertine for their bathroom walls and wants you to fit them direct onto the plaster skimmed surface..... Do you point out the dangers, give a range of safe options, and then tile straight onto the plaster cos customer says they want that done without the fuss and expense of expensive over boarding? Or do you walk away from the job (knowing that another tiler with less scruples will take on the job)? I have to be honest and say I have accepted one such job (customer had recently skimmed walls did not want over boarding) and walked away from two others in the last two years (old walls customers did not want over boarding). However - I have found customers are increasingly willing to accept additional preparation costs to get best results (e.g. Ditra on floors and waterproof boarding options on walls).
Exceeding substrate weight limits.

Ive just text the customer asking for a decision as I have to keep my diary straight.
Customer want trav on plastered walls. Gulf stone on s&c screed insisting at 3 weeks down and at 100mm deep it was dry cos it had been hot 25°+ for a few days. Someone will do it for him but im not taking that chance.

evening men... was thinking to myself the other day,, about liquid and on the roll waterproof membrane and how they effect tile weight limits and does it make any difference to the limits... as you are tiling on to a membrane and not to surface stated it in weights and limits guide.. thanks
As far as weight goes itll only reallt need consideration if its going onto plasterboard. It would easily be less than 1Kg psm. Allow a kilo in your weights and you'll have it covered.
Always follow the manufacturers instructions when it comes to the prep of the substrate before applying your WPC.

Gypsum plasterboard will absorb moisture like a sponge if water creeps through the grout joints...

Ok i understand that... I just want to know if the 30kg psm weight limit applies to plasterboard even if it has a water proof membrane on it. Thanks

Is that a liquid membrane or the fleecy type...

Hi white beam.. It is just a theoretical question.. I would mind knowing your opinion on both materials. Much appreciated thanks
