Not when I worked in Europe Alan , the screed companies always sanded their work it was recognised that this was their responsibility and if the tilers did it it was counter charged against the screed companyIm not aware of any legal cases where the tiler has been sued for not identifying the screed nor any where the screeder has failed to leave data etc.
in this instance if the floor was dry and anhydrite adhesive was used there is a good chance t will stay stuck. no guarantees though im afraid.
as for legal responsiblity on the screeder in europe its the other way round the tiler takes responsibility for the screed being right, the screeder takes it for the prep and insulation and so on through the contract chain. that siad there are probably as many failures if not more in europe than over here. that is testament at least to the work we have done in getting the correct info out there. and really it doesnt take a lot of finding.
