Hi and welcome

Hi everyone, just wondered if any of you could help me out. I am going to look at a job tomorrow which is a shower cubicle that needs tiling the client has told me that 2 walls are sand and cement render with skim and the other wall is plasterboard(not skimmed) Tiles are B&Q travertine but dont know size yet she just says they are big, heavy and rectangular. can anybody tell me the maximum weight per m2 for the different substrates so I can explain to the client why I will be recommending using backer board at least for the plasterboarded wall.
Thanks
Ed

plaster board is about 30 kg, the render would have been fine if it was,nt skimmed , skimmed walls about 20 kg

I've had to over board a wall this week to straighten it up (dot and dabbed plaster board) and something occured to me, surely the weight limit for tiling is greatly reduced per square metre as the original substrate is supporting the dot and dabbed board and the tile/addy/grout. Am I wrong in thinking this?

What was the on the wall Bri? if you are back to brick or block work will be fine with plenty of dry wall adhesive, they may be a problem if its on plaster, regarding how strong the plaster is with all the extra weight.

Any chance of screwing throught? I dont like overboarding without screwing it back for that reason.

It was existing plaster board screwed to stud work, I screwed the bottom in but had to dab the top as the wall fell away as it went up to the ceiling, I suppose I could put long screws through the top now that the dabs have gone off. I have seen walls dot and dabbed over existing rendered and skimmed walls, so I guess this is not ideal.
