Exceeding substrate weight limits.

Tilers Forums Official Sponsors

Liquid would be next to nothing, the fleece would be about 1/2 kg m2 maximum including the adhesive used....plasterboard takes 32kg m2.
 
BAL state that their liquid kit (wp1) can hold up to 32kg per m2, it will be substrate dependant though, skimmed PB will still only be able to take 20kg tanking or not. So according to this data the wp1 kit won't be suitable for heavy stone even if it is fitted to a cement board, although the substrate can cope with the stone, the liquid membrane can't.

Neither Schlüter-KERDI or Durabase WP publish weight restrictions on their web sites. Assume that means that they don't have one.

Had a look at a job yesterday its a new build ,Bathroom and Shower en-suite about 50 m2 walls are all ply the tiles are 600 x 300 porcs,boxes stated the weight of 32 kg.I explained about the weight issue and he more or less said "if your'e not interested then there are other tilers that would do it" and he said "he never heard of this before and on his last two build's the tiler never mentioned this",now in a bit of a dilemma ? do I do it or walk,its a nice job and I really do not want to loose it there are another two tilers after it and I will not know until Monday if I have got the job.I am aware of the weight's what you can put on plasterboard/backer board just a bit unsure with ply always work on the same as plasterboard unskimmed,have been trolling the net is there a printable weight limit table for this so I can show customers what the limit is ?.I do believe that this house will be his home just cant understand why they dont listen.
